Small pitch LED display will lead revolutionary changes Published：2018-09-04
LED full color display has been integrated into all aspects of our lives, especially the rapid development of technology in recent years, as well as the advent of small-pitch LED displays. Some experts predict that a revolutionary change will occur in the field of LED displays. In the next 10 years, LCD monitors will likely exit the mainstream stage like CRT monitors and will be completely replaced by small-pitch LED displays.
At present, energy-saving, lightweight, small, high-confidence LED products occupy the mainstream position, and LEDs just meet these requirements. LEDs are all-solid cold light sources that are smaller, lighter, and more rugged. They operate at only two volts and last for more than a decade. Although the luminous efficiency of the LED is not high, since the spectrum of the LED is almost entirely concentrated in the visible light band, the efficiency can reach 80-90%.
The LED can be almost infinitely spliced according to the demand without visual seams, the picture is complete and freely divided; secondly, the color and brightness consistency are good. Compared with LCD and other splicing screens, the color and brightness consistency of small-pitch LEDs is obvious, and can be corrected point by point on the spot after installation, so that each pixel emits light uniformly. Liquid crystal splicing also has dark edges, black corners, etc., and it is irreversible and cannot be repaired; again, the LED can be adjusted from 2500K to 10000K color temperature and wide area, wide color gamut, restore true color, can be used for color requirements. Accurate industry; in addition, high gray levels, high contrast and high refresh rate make LEDs perform better with better color performance, faster response speed and zero heat dissipation.
With the rise and growth of the emerging civilian commercial market, products such as small-pitch LED TVs have been quickly recognized, which will accelerate the development of small pitch LED display. The small spacing is not limited to the control room. The space in the high-end indoor display market is huge, especially in the high-end conference and command and control markets where high-brightness DLP professional engineering projections are applied. It is easily broken by small-pitch LED displays. In addition, for applications that do not require high-resolution maps or engineering drawings, such as various image projects, the background wall of the broadcasting industry, commercial brand display, public information display, intelligent transportation and other application fields, these are also the driving force for the continuous development of small distances. .
On the other hand, small-pitch LED displays do not have the ability to completely replace LCD TVs. On the one hand, with the increase of resolution, the dot pitch is reduced, and higher requirements are placed on heat dissipation, life, color consistency, maintenance, etc., and it is not easy to solve. On the other hand, "low-bright high-gray" has become a threshold that LED manufacturers must enter to enter high-end display applications. Small-pitch LED screens must solve the problem of reducing brightness without losing grayscale and image quality. At the same time, the cost is too high to limit the development of small spacing to a certain extent. It takes a certain amount of time for LCD TVs to dominate the market.
