The next few years the small spacing LED screen will maintain high growth
Since the 2016 LED small pitch display market began to enter the real outbreak of the growth period, the major screen enterprises continue to increase this aspect of technology research and development and market layout. Led display products continue to achieve a breakthrough point spacing, pixel density increased dramatically, the resolution also will be greatly improved, the application of the market to accelerate the penetration of large-screen display areas. It can be seen, LED small pitch display market prospects are very impressive.
With the continuous improvement of led display technology, small distance led display more and more perfect. After the industry's precipitation, p2.5 are called the following small distance led display. According to the data that the current small spacing is the smallest p1.5, there are models including p2, p1.9 and so on. Small distance led display is the purpose of doing high-definition, into the home appliance industry. Now the led display are used for municipal, commercial media. If you do into the home appliance industry, the market will develop into a monopoly technology.
Even if the product is p1.5 or smaller specifications, to achieve full HD resolution (1920 × 1080), the screen size will reach 144 inches, which is very large space requirements, which does not include the size of the base size, To find one side can put it down the wall is not easy to find, this also does not include the construction space.
The price decline is also an important factor, compared to large-size LCD TV, small distance led display at least 40% cheaper. There are industry veterans believe that the LCD panel to do large size cost is too high. To 120-inch, for example, the cost of LCD panels in about 80-120 million, and use the led display screen to do only 50-60 million, the cost is obviously greatly reduced. In addition, the industry for small-pitch LED TV to replace the LCD TV mosaic wall seems confident, perhaps six months later we can buy LED TV as a home.
From the price side, the LED lamp beads as the pitch becomes smaller, we installed the LED lamp beads is more intensive, small distance led display requirements are very high, and cooling, circuit or power compared to other led display is more High, and now, the small distance led display technology is still in development, not very skilled, it caused a small distance led display price is not expensive, but with the small distance led display technology To more skilled, more and more high capacity, our prices will decline.
From the maintenance side, although the led display life is very long, but because the lamp beads are more, and the indoor requirements of the thickness of the outdoor high, resulting in cooling effect is not very good, prone to failure. This is for the small distance led display is relatively difficult to maintain, but now has a perfect technology, front maintenance led display.
Led display area of the bright area, is the luminous surface of each pixel and the proportion of the entire led display pixels. Led display is arranged by the discrete pixels, pixels and pixels between the Hengda different. Some distance near the visual effect is not very good to watch, and the brightness will be uneven grainy things, if the light source in a small pixel where a pixel brightness index will be very high, it will cause a strong The visual impact. Flat LED display is the industry recognized TCO'99 standard requirements, LED lights can not be less than 50% look, but now many of the market led display are not required. TV's low-pass filter cut-off characteristics also directly affect the filling factor of the different led display of the appropriate shooting distance. Fill the coefficient is much smaller than the filling factor, so the camera is far away. If the system low pass filter passband is 4MHz, high frequency attenuation characteristics of 12db / octave, then the filling factor of 25% of the shooting distance than the fill factor of 50% more attenuation 1.15db, shooting distance need to increase about 10%. Fill the coefficient is improved, is the application of a wider display screen, the color is more ideal, the perfect solution to the glare, and now the LED display to create conditions are getting better and better.
Led display market has been widely used in advertising media, sports venues, stage performances and other daily life in all areas, has become China's LED application of the most mature a market segment. When the general product margins become lower, the price melee to the public when the weak manufacturers, the power of the market segmentation should be a breakthrough in the effective way to break through the tight encirclement. At the same time, with the small distance led display is increasingly widely used, prices also will be further reduced, the application area also accelerated expansion, the future will be fully into the media, advertising, cinema and other commercial applications. And the relevant agencies are expected to 2018 small gap LED market size will be close to billions, the next three years to maintain high growth.
