Problems solved by technology

Therefore, the current point-by-point calibration method of LED display screens has disadvantages such as inability to correct due to environmental reasons, low calibration efficiency, and large calibration errors. At the same time, this calibration method requires a lot of manpower, material resources and time, and has low economic benefits.
[0005] For the current problems of large-screen calibration and on-site calibration that are difficult in engineering, no effective solution has been proposed so far

Abstract

The invention discloses an LED display correction system, including an optical collection system, an LED display control system and a main control computer. The optical collection system comprises an enclosed case, a module installation unit and an optical collection unit. The module installation unit is arranged at one end of the enclosed case and is used for holding a to-be-corrected LED display unit. The optical collection unit is arranged at the other end of the enclosed case and is used for collecting display information of the LED display unit. The LED display control system is connected to the to-be-corrected LED display unit to control the to-be-corrected LED display unit to emit light. The main control computer is connected to an optical sensor, and is used for receiving the display information collected by the optical collection system and sending the display information to an image processing system for image processing, so as to obtain correction data.

Description

technical field [0001] The invention relates to the field of LED correction, in particular to an LED display correction system. Background technique [0002] Usually, a large LED display is spliced ​​by multiple LED display modules. Due to the manufacturing process and other reasons, the performance of each LED chip has certain differences. For example, there may be a 20% difference in the brightness of the LED chip, that is, the three channels of red, green, and blue have a 20% difference in brightness; at the same time, due to the pressure of manufacturing costs, LED chips with a wavelength difference within 5nm are generally regarded as qualified. , so there is also a certain color difference. When the display modules made of these different LED chips are integrated into an LED display, if these differences are not sufficiently compensated, there will be differences in the brightness and color of the LED display visible to the naked eye. In addition, during the use of ...
