Problems solved by technology

Although the system and method described in this application can accurately adjust the LED display, the processing speed is slow, and the central control module has a large amount of calculation, so it is necessary to adjust each light point in the LED display one by one.
Moreover, if it is a large-scale planar light-emitting device assembled by multiple LED displays, if it is adjusted, the application cannot balance the brightness between the light-emitting modules, and the efficiency is low and the speed is slow.

Description

technical field [0001] The invention belongs to the technical field of LED display screen adjustment, and in particular relates to a system and method for uniformity adjustment of a plane light-emitting device. Background technique [0002] The large-scale LED display cabinet is composed of multiple LED display modules, each of which contains a large number of light-emitting diodes. Various factors such as different optical characteristics of LED light spots, component aging, driving error, inconsistency of the light point itself, dust on the light point, and shielding of the hat brim to protect the light point will cause the brightness of the screen light point to be uneven. [0003] At present, the main ways to solve this uneven phenomenon are as follows: one is to improve the consistency of the optical characteristics of LED lights. In this way, it is necessary to ensure that the light-emitting diodes in the entire cabinet have almost similar optical characteristics. In ...
