Method and system for correcting brightness and chromaticity of LED display

Abstract

The invention provides a luminance-chrominance correction method of an LED (Light Emitting Diode) display screen and a luminance-chrominance correction system of the LED display screen. The method comprises obtaining the configuration file of a to-be-corrected LED cabinet of the LED display screen, wherein the configuration file comprises the batch information of lamp points of each batch on the to-be-corrected LED cabinet; according to the use time of the to-be-corrected LED cabinet and the batch information of the lamp points of each batch, calculating the correction coefficient of the lamp points of each batch; uploading the correction coefficient of the lamp points of each batch to the to-be-corrected LED cabinet for correction on the luminance and the chrominance of the lamp points of the to-be-corrected LED cabinet. According to the method and the system, as the correction coefficient of the lamp points of each batch is determined by using the batch information of the lamp points of each batch and the use time of the to-be-corrected LED cabinet, the correction coefficient can be conveniently and rapidly determined; moreover, image collection equipment is not needed to determine the correction coefficient of the lamp points; therefore the LED display screen has a better display effect, and the problem of luminance and chrominance differences between different batches of LEDs is effectively solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a chromaticity correction method and device after light emitting diode (Light Emitting Diode, LED) mixed lights. Background technique [0002] As we all know, LED display modules such as LED light panels, LED cabinets, and LED displays are composed of a large number of LED lights. In order to achieve the best display effect after combining LEDs of different colors and parameters, it is necessary to first Mix the LED lights evenly, in order to achieve a balanced distribution of the LED lights on the LED module in terms of brightness and wavelength light parameters. Among them, mixing LED lights evenly can be called mixed lights. [0003] Since the 21st century, the color display industry has developed unprecedentedly, and LED display screens have spread all over the central squares and commercial buildings of all cities. LED display is well received by people for its un...
