Led display is constantly developing, and more and more production companies. Because the display technology is generally consistent, the competitiveness will be extremely fierce, and the future LED display will tend to be thinner and higher. And other products. As the field of application of led displays becomes wider and wider, people's understanding of it has also deepened. From a technical point of view, Shi Juguang said that there are four major problems in China's LED display technology:
First, led display control chip problem
Led electronic display as a new high-definition display media, with its clear image and high-performance playback capabilities, more and more people pay attention. For the LED display unit, the three-primary LED die is the core device. Therefore, high-quality dies with small wavelength difference and good luminescence intensity should be used, and this technology is mainly in the hands of internationally renowned large enterprises.
Second, the problem of heat dissipation
Because the outdoor environment temperature changes greatly, plus the display itself will generate a certain amount of heat. If the ambient temperature is too high and the heat is not good, it will most likely cause the integrated circuit to work abnormally or even be burned, which will make the display system not work properly.
Third, the problem of insufficient brightness
Led display in a variety of outdoor environment, must be able to ensure sufficient brightness to transmit information, so brightness is particularly important, and due to the lack of brightness of led lights, so that the current led lights in the lighting industry can only serve as a supporting role, mainly For decoration, this will be a huge challenge for the comprehensive application of tens of thousands of led lights.
Fourth, led lamp chromatic aberration problem
The application of a single led lamp bead basically has no chromatic aberration problem, but if a plurality of led lamp beads are used in combination, the chromatic aberration problem will be highlighted. Although there are techniques to improve this problem, due to the limitations of domestic technology and production level, there are still differences in the same batch of led lamp beads in the same color zone, and this difference is difficult to escape the naked eye review, thus it is difficult to ensure the LED display. Color reproduction and realism.
In order to become a leader in the industry, led companies must first break through these four major problems in order to be invincible in a highly competitive market.
