Small spacing LED display broad prospects for the development of three bottlenecks restricting

Small spacing LED display market has great potential, but the display effect, high resolution with load, splicing gap has been the bottleneck of high density small spacing LED display, limiting the application of small spacing LED display.

The small pitch LED display screen has the advantages of seamless splicing, modular maintenance, natural color reality, better display uniformity and wider color gamut space. However, the display effect, high resolution with load, splicing gap has been the bottleneck of high density small spacing LED display.

The image display shows the effect of small spacing effect by light, the first sweep dark, low ash and low ash redness, uneven brightness, afterglow phenomenon will cause image blur; first sweep dark led LED brightness dark gray color balance is low; low ash redness phenomenon. In addition, the causes of low gray brightness non-uniformity mainly come from the inconsistency of LED, and the difference of driving chip itself. These problems can be controlled by driving the IC with the control system. At present, there are high-end driver IC integrated processing functions and interface for the above problems. By using the control system to adjust the parameters, the display effect can be improved effectively.

High resolution loading is another problem. Small spacing display LED light dot spacing is small, in the same area with greater resolution. To improve the resolution, if still using a cassette receiving set, display performance indicators will be lower; and in the case of limited space, and cannot be installed a cassette carrying a receiving box. In order to solve the problem, the receiver can be customized according to the structure of the box body, so that the receiving card and the module can be matched with each other, and the utility model has the advantages of large carrying capacity and high performance.

The rapid development of the small screen display to the point by point correction technology challenges. At present, through the use of machine vision technology and human visual characteristics of the gap detection and correction technology, can solve the problem of stitching gap correction.
