Laser projector advantages:

1. Clear image

Ordinary projectors require us to put them in the right place to the screen as far as possible, but the laser projector 1080p does not have this problem. Even if the projector is placed in the corner, the projected picture does not have any distortion. Laser projection does not produce ambiguity anywhere.

2. High chroma

In terms of display effect, because laser projector 1080p simulates natural colors, the colors and layers are also more abundant. The wavelength of the light is fixed, so it looks comfortable, without the blinding discomfort of the bulb. More importantly, ultraviolet radiation without traditional light source makes the eyes relax when they look at the picture, which is incomparable with either projection device or active luminescence device.

3. Long service life

The lifetime of laser projector 1080p is four times longer than that of a traditional projector.

 Disadvantageof laser projector 1080p:

1. Relatively expensive

The unit price of laser projector 1080p is higher than that of an LED projector. Although the service life of the laser projector is longer, once the light source is damaged, the cost of laser projector 1080p is higher than that of a traditional projector.

1 Entry-level individual users

Generally speaking, we should first pay more attention to economic practicability and ease of use, instead of chasing too high resolution. Even for image processing enthusiasts, a resolution of 600dpi can meet the basic requirements. In terms of ease of use, attention should be paid to whether there is a detailed installation and use manual attached, whether the scanning software interface is easy to understand and to set various options, whether there are some convenient function keys designed, etc.When buying, see whether the color style of the scanner is suitable for one's own aesthetic habits. Choosing a satisfactory appearance, volume and style can well decorate the family environment.

2. Ordinary office users

If you are an ordinary office user, the purpose is very clear, that is to scan faster. Therefore, when purchasing, more attention should be paid to the scanning speed of the scanner and whether it is equipped with a paper feeder, which is conducive to the automatic continuous scanning of manuscripts. In terms of resolution, about 1200dpi can meet almost all the requirements. As for color, it is not as high as that of professional users because of the common color deviation of computer screens. In addition, the ease of use and intelligent design of the scanner are equally important to ordinary office users. Humanized design can save some complicated scanning steps, especially for users who often need batch scanning.

3. Professional users

Users who are engaged in professional image processing in graphic design, advertisement production, printing and typesetting and other fields have high-end requirements on all aspects of high speed ocr scanner performance, especially the scanning effect, which requires color restoration, clarity and level to be higher than that of ordinary scanners. When purchasing a scanner, in addition to paying attention to high hardware color bits and high resolution (generally above 1200dpi), you should also know another important parameter of the scanner: dynamic density (this parameter is generally less than 2.0 for ordinary scanners). The higher the dynamic density, the stronger the scanner's hierarchical performance. It is generally necessary to scan films, negatives and other transparent manuscripts. Since the storage space occupied by higher resolution scanning pictures is certain, if the scanner is equipped with a faster SCSI interface (or IEEE 1394), the data transmission time can be greatly shortened and the work efficiency can be improved. Thus the requirements for volume, weight and appearance characteristics are not important.

4. Comprehensive guidance

The restoration degree of an original image by a auto book scanner is not only related to the above resolution, but also affected by the color depth and gray scale. The scanning speed is closely related to system configuration, scan resolution setting, scanning size, magnification, etc. Fast scanner speed is important, but the image quality cannot be affected by improving the speed. Some scanners with very fast scanning speed will lose some image information during scanning. Therefore, you must try to scan it yourself before making a formal purchase. It is best to bring along some different scanned originals, such as photos, printed images, newspaper text, etc. At the same time, you can also try to scan some objects, such as keys and cigarettes, to see if the effect is satisfactory.

Mini projector is used more and more widely, not only in some business occasions, but also in many people's home film systems. But most people don't care much about how to use the projector correctly.

In fact, there will be many small problems in the use of the mini led projektor. In addition to the basic installation and maintenance, there will be some puzzling occasion in the use of the projector, which will make the user misunderstand the projector. Today, I'll explain the common problems that the projector occasionally has, so that users won't be too flustered in the use process.

The first is about sound.

Many users will be confused about the sound when using the projector. The speaker of the projector is very small. The main function of the projector itself is to show the perfect picture, and the loudspeaker takes up too much internal space, so the loudspeaker design of the projector will be relatively small, so it is better to cooperate with the external sound equipment when using the projector. At present, most of the projectors on the market are equipped with sound output terminals, which is also fully prepared for the external sound equipment.

Secondly, the brightness of the projector.

Many users responded that the projection screen was not as bright as before after the projector was used for a period of time. They asked if there was a quality problem with the projector. Actually not. At present, most projector products use the built-in bulb penetration projection mode, and the projection brightness is mainly determined by the bulb, while the display brightness of the projector's bulb is inversely proportional to its use time. Generally speaking, after 120 hours of use, the brightness of the bulb will drop by 20% - 30%. Therefore, users must pay attention to protecting the projector's bulb in normal use. Do not use it for a long time. Try to turn off the projector when not in use.

Finally, the problem of the picture.

Sometimes the projector has the state that image is unstable state, or the picture blurs and shakes. This is also not a problem with the projector function. Some tips are needed to solve it. First look at the image instability.

The output image of the projector is unstable and has stripe fluctuation, which is mostly due to the inconsistency between the power signal of the signal source and the power signal of the projector. The user needs to plug the power of the projector and the signal source into the same terminal block, which can basically solve this problem.

The condition of blurred and dithering picture. Generally speaking, if the projector is too far away from the signal source, it will weaken signal, and the performance projected on the screen can be blurred or dithered. So when using the projector, it is noted that the distance between the signal source and the projector can not be too large. If the distance between the two is large, it is recommended to use a signal amplifier to help the projector receive the signal from the signal source.

With the increasing popularity of mobile phones, taking pictures instead of cameras, music playback functions instead of MP3s, and various scanning apps are emerging. The parameters and technology of mobile phone camera and camera scanner are getting higher and higher. Is it still necessary for a clunky and complicated scanner?

Whenever a new technical solution comes into being, it always conflicts with the old one.

Will the popularity of WeChat replace SMS? It won't. Although most people receive SMS verification codes, their formal security and uniqueness prevent them from being completely replaced.

Will the mobile app replace the easy book scanner? It won't.

1) Scan quality. The scanning app solution is based on CMOS technology, which is the camera. The CMOS effect itself is not as good as the CCD, and the scanning effect of the App depends in part on the camera pixels of the mobile phone itself.

2) Professionalism. Many applications are now integrated on mobile phones, and a single mobile phone can meet many needs. However, we still consume cameras, MP3s, game consoles and other products to meet our more segmented needs. In more rigorous occasions, mobile phones cannot replace cameras, Meitu Xiuxiu cannot temporarily replace PS, and apps cannot replace scanners.

3) Application scenarios. In general, apps are mostly used by individuals. When we scan documents daily, such as small diaries, it is not necessary to purchase a scanner, and the App is sufficient. But the biggest market for scanners is at the corporate level. Can you imagine what it looks like to scan millions of documents with App in archives, libraries, banks, public security, procuratorates, courts, etc.? No matter how high my salary is, I've been holding my phone mechanically to scan, change files, and generate finished products ... I won't do it either.

The advantage of App is that it is portable and fast. It's great for personal use. However, it cannot always replace the scanner itself.

The size of space

The size of the space is the size of the living room, movie room, etc. where you use the projector. If your living room area is more than 20 square meters, you can consider buying a led home cinema projector; if not enough, it is not recommended.

Price

The price gap of mini home projector is large, generally from a few thousand yuan to about 50,000, or even higher. The prices of foreign brands are higher than domestic prices. Domestic projection prices are lower. The reason is not explained in detail. For most consumers, products below 30,000 yuan can meet household needs.

Brightness

Brightness is one of the most important indicators for purchasing a projector.

Noise

Those who have never used a projector do not know that the projector will make noise when used. The noise of some projectors can severely affect viewing and is unbearable. When purchasing a projector, considering low noise should be an important part of the purchase. At present, many manufacturers have launched low-noise projectors, and the price is not expensive. Generally speaking, products with a noise level below 40dB are acceptable, but when buying, you should listen and compare yourself in a quieter environment to see if it will interfere with yourself.

Choose DLP or LCD

Whether it is LCD or DLP is actually not so important. What we need to see is the effect of the projector. And the effect of a projector is inseparable from many things such as lenses, light bulbs, and circuits. In principle, LCD projectors are the most common and their prices are relatively low. The biggest advantage of LCD projectors is that the colors are great. The three primary colors of red, green and blue are completed by three separate LCD panels. The brightness and contrast of each color can be controlled individually. And three colors of light can reach the screen almost simultaneously, so various colors can be reproduced realistically. Although the color reproduction of DLP projectors is slightly worse, the three-color light of a single-chip DLP projector is reflected by the same micromirror to the same pixel, and there is no convergence problem, so the black area is truly black, and the edge of the pixel will not appear Some burrs and shadows in the LCD. Therefore, when showing some thin lines, DLP projectors are clearer and sharper than LCD projectors, black and white are more pure, and gray levels are richer. Of course, the biggest advantage of a single-chip DLP projector is its small size and light weight. Many products even have only 1-2 kg. Generally speaking, DLP projectors are slightly more expensive. Seeing is believing. Whether it is LCD or DLP, it is recommended to compare carefully at the time of purchase.

Trapezoidal correction

In the use of the projector, the position of the projector must be at right angles to the projection screen as far as possible to ensure the projection effect. If the verticality of the two cannot be guaranteed, the picture will be trapezoidal. If it is not on the ceiling, but on the table, it is difficult for us to guarantee "vertical". In this case, we need to use the "keystone correction function" to correct the keystone to ensure that the picture has a standard rectangle. Keystone correction usually has two methods: optical keystone correction and digital keystone correction. Optical keystone correction refers to adjusting the keystone by adjusting the physical position of the lens; another type of digital keystone correction is software to achieve keystone correction. At present, almost all projector manufacturers have adopted digital keystone correction technology, and most of the projectors using digital keystone correction support vertical keystone correction function, that is, the projector can adjust its height in the vertical direction. The resulting trapezoidal is trapezoidally corrected in the vertical direction by the projector. The picture can be made rectangular, which is convenient for users.

The minimum width of the projector is unlimited. For the same projector, the distance is longer , and the screen is larger. The distance is closer, and the screen is smaller. If the curtain is too small to buy, you can customize it, or you can brush the wall white.

If you hang, use a dlp mini projector hanger, with one power cable, one audio and video cable. If there are many video signal sources, a video switcher can be added to switch TV programs, video players, camera videos, etc. together. The camera is easy to connect, just switch the camera video signal to the video switcher. It ’s free to see what you want.

The most important thing to pay attention to is: when shutting down, use the remote control to softly shut down, and then cut off the power after the fan has completely stopped, so as to truly cool the protection bulb. In addition, take a while to remove the air filter and clean it. And don't look directly into the projection lens, because it hurts your eyes.

Use a fixed universal hanger to install the projector. If it is an electric hanger, generally the hanger is fixed on the house beam and then the projector is hung, and the height is generally about 30cm below the house.

When you turn on the power switch, the bulb should be on, and the fan will start rotating. If the fan does not turn off, immediately turn off the power and stop using it, and ask for the reason.

All the cables must be embedded in place (video cable, audio cable, socket ...), the location of the portable dlp projector must be considered in advance, and the size of the projection cloth must be accurate. It is best to choose a socket with a switch if you want to place the projector in the ceiling mount position. If it's an electric screen, you also need to put the power there. It is best to make a ceiling cassette in the place where the curtain is hoisted, and it is necessary to strengthen the place where the curtain and the projector are installed.

Many consumers are confused about the brightness parameters of the mini hd led projector when purchasing a projector. Perhaps in the eyes of laymen, evaluating the brightness of a projector can only be judged by the value. And as people gradually increase their expectations for high brightness and high resolution, many manufacturers will choose to use the concept of stealth to change the parameters in order to attract attention.

However, in fact, there is not an absolute positive relationship between the effect shown on the screen and the number of lumens marked. Not a projector with a higher lumen is better. So what exactly does a projector lumen do? Let's take a look at the mystery of lumens and learn to say no to false parameters.

Generally speaking, the lumen of a projector is divided into several units. There are only two of them in our daily life, one is the brightness of the light source, and the other is ANSI lumens.

The brightness of the light source refers to the "most original light-emitting brightness level" provided by the laser, light bulb, and LED light in the projector. In simple terms, the brightness of the light source is the brightness that has not been cut by the lens or other factors.

Another type, ANSI lumens is the international standard unit of 2500 lumens projector recognized by the world.

ANSI lumens is the brightness after layer after layer of reduction. Use the sun as a metaphor. The sun itself is the brightness of the light source, and the sunlight shining on us is the brightness that the projector projects on the wall after being cut. The brightness projected onto the wall is ANSI lumens.

According to relevant calculations, the light source brightness of 3500 is approximately equal to 1000-1200 ANSI lumens. Therefore, be sure to look for ANSI lumens when choosing a projector.

There may be consumers wondering what is the relationship between the level of lumens and the size and clarity of the picture?

As the brightness of the projector (lumens is the unit of brightness) increases, the picture projected at the same screen size will become brighter. So it looks clearer, but the resolution does not change; the increase in lumen has nothing to do with the screen size, but the brightness will change as the screen size changes. For example, the screen size is larger and the brightness is lower.

According to the size of the indoor space, in the space of 15-30 square meters, 100-800 ANSI lumens is recommended. In the space of 35-50㎡, it is recommended to be between 1500-2000 ANSI lumens. In the space of 60-100㎡, it is recommended to be between 3000-4000 ANSI lumens. In the space of 120-200 square meters, 4000 ANSI lumens or more is recommended. The two are well understood, because the lumen is proportional to the area of the house.

Although now we have entered the digital era, and e-books are gradually popular and popular, many organizations and individuals think it is necessary to convert paper materials into electronic documents for preservation.

According to media reports, Dai Nippon printing announced yesterday that it had launched the world's fastest 3D book scanner developed in collaboration with professors Masatoshi Ishikawa and Yoshihiro Watanabe of the University of Tokyo. The ocr book scanner scans up to 250 pages per minute at an amazing speed.

As we all know, the speed of general scanning products is not very fast. Among the all-in-one products we tested, the product with the fastest scanning function also takes more than 10 seconds to scan a piece of A4 paper. Then the number of pages scanned per minute is 6. Compared with this high-speed scanner, it's snail speed.

This multi page scanner is different from the traditional one. When scanning, it turns pages at high speed through a mechanical device, takes 3D pictures of pages through two powerful cameras, and uses real-time stereo image identification technology and high-speed aberration correction algorithm to realize fast and high-quality book scanning. In addition, the book scanner overcomes the disadvantage that the traditional scanner must open the book and lay it flat, without disassembling the book.

According to reports, in order to achieve the best printing state, the device has built-in software, which can scan and analyze, correct errors and synthesize two pictures. Finally, it can scan the pictures with the output pixel of 400 PPI, and convert the high-quality output results into e-books, PDF and other formats

iCODIS Megascan X9 scanner could also deliver promising results with its high-pofile performace.

Most users will pay attention to the performance of the hd mobile projector in color when they purchase the projector. When you buy a hd dlp projector, you need to pay attention to several key parameters, such as brightness, resolution and contrast. These parameters largely determine the image performance ability of the projector. However, many friends realized that although the parameters of different brands of projectors are basically the same, most of them are quite different in color performance. So what influences the color of the projector?

First, the problem of light sources. Light bulbs are used in traditional projectors. The principle of light source of bulb is to electrify the bulb filled with rare gas, which can ionize the rare gas and generate visible light by high voltage discharge. This kind of high intensity gas discharge light source is not pure. There are a lot of messy light, which affects the color of the projection picture.

The impure light from the traditional light source affects the color performance of the projector.

Now there are many monochromatic light sources on the market. The principle is to mix the blue light source (LED or laser) with the Fluorescent Pink wheel to form "white light". But the performance of this white light is not as good as that of the three primary color light source. In addition, in order to improve performance, there are also two-color light sources, such as red laser plus blue laser. The color effect is much better than monochrome light source. Generally speaking, tricolor light source is the best, but the cost of monochromatic and bicolor light source is low.

With different color wheel structures, the color effect of projection image is different

Second, the problem of color wheel. Now, six segment color wheels are mostly used in the projectors on the market. Compared with the early three segment color wheel, the image color will be better. Although different projector products all adopt six segment color wheel, the color of the remaining three segment color wheel is different except RGB three segment. For example, some projectors add white segments to RGB tricolor wheel in order to improve the brightness of projection picture. In order to present a better color effect, some projectors use rgbrgb cycle color segment. What's more, the proportion of each color segment on the color wheel of different projector products is also different, and the image color presented when using is also different.

Adjustment method of color temperature and the brightness of the light source affects the color of the projector

Third, the adjustment of the projector's later software, such as the adjustment of color temperature and color accuracy. The color temperature of the projector is generally 6500k, because such a color temperature will not make the screen have too much color trend. If it is lower than 6500k, the color of the screen will be warmer, otherwise the screen will be cooler. In fact, the brightness of a projector light source has a great impact on the later adjustment of color temperature of the projector. The higher the brightness, the larger and more flexible the adjustable range of color temperature. For example, for the projector with traditional light source, it is easy to adjust the color temperature to 6500k for a brightness of 3000 lumens; for the projector with LED light source with lower brightness, the maximum brightness is 1000 lumens. For the effect of the picture, the color temperature usually reaches 890k or even higher.

Most users will pay attention to the performance of the hd mobile projector in color when they purchase the projector.

For the effect of the picture, the color temperature usually reaches 890k or even higher.

At present, there are a variety of media publicity methods, among which outdoor advertising is not to be underestimated. In this filed, many advertisers and advertisers want to catch people's attention by shining bright lights, and this form of advertising also causes serious light pollution. Light pollution continues to harm human health, and many countries have begun to regulate it. With the flattening of the outdoor advertising market and the increasingly developed media industry, and the increasing demand of such users, the indoor advertising multimedia under the application of new media is quietly growing.

Among them, the indoor new media application covers the fields of high-speed railway, airport, subway, shopping mall, underground parking garage, hotel lobby... Laser multimedia projector plays and important role in this form of advertising. With the technical innovation of projector products, the current life of laser projectors can reach 20,000 hours. The light source has the advantages of pure, environmentally friendly, not dazzling and so on. At the same time, the laser projector also has a more stable system, which fits the current long-term uninterrupted advertising. Comparing with other forms of advertising in indoor advertising are more cost-effective, and the cost reduction is also an important reason for new media to speed up the rise.

DHN, as one of the most professional laser projector manufacturers in the multi-brand field, must be the first choice in the new media industry. In order to solve the technical problems arising from the promotion of the new media industry, DHN should solve the difficulties in the market from the source of research and development, so as to better serve the new media industry.
