Four led display technology problems

Time:2018-11-30 Views:143

Led display is developing continuously, and more and more manufacturers are engaged in it. Since the improvement direction of display technology is generally the same, the competitiveness will be extremely fierce. In the future, led display will tend to be thin and high-power products.With the application of led screen more and more extensive, people‘s understanding of it is also deepening.In terms of technology, drenser believes that there are four major problems in led display technology in China:

First, led display control chip problem

Led electronic display, as a new display medium of true color and high resolution, has been paid more and more attention by people for its clear image and high performance.As for the led display unit, three-color led core is its core device, so it should use high-quality core with small wavelength difference and consistent luminous intensity, and this technology is mainly in the hands of internationally renowned large enterprises.

Second, the problem of heat dissipation

Because outdoor environment temperature changes greatly, plus the display screen itself will produce a certain amount of heat.If the environment temperature is too high and coupled with poor heat dissipation, it is likely to lead to the integrated circuit is not working properly, or even burned down, so that the display system can not work properly.

Third, insufficient brightness

Led display in variety of outdoor environment, must be able to guarantee enough brightness to convey information, so the brightness is particularly important due to the led lamp bead brightness is not enough, make the led lamp bead can only act as a supporting role in the lighting industry, mainly used for decoration, the integrated use of for the tens of thousands of led lights bead will is a huge challenge.

Fourth, led beads color difference

In the application of single led beads, there is basically no color difference problem, but the comprehensive application of many led beads, the color difference problem will be highlighted.Although existing technologies have been used to improve this problem, due to the limitations of domestic technology and production level, there are still differences in the same batch of led beads in the same color area, and such differences are difficult to escape the inspection of the naked eye, so as to ensure the color reductivity and verisimilitude of led display screen.

Led enterprises to become the leader of the industry, must first break through the above four problems, in order to be invincible in the competitive market.
