Abstract

The invention discloses an LED panel pixel correction method and apparatus. The method comprises the following steps: receiving single-frame video data, wherein the single-frame video data is one frame of data in a video to be corrected; storing the single-frame video data to a dynamic memory; reading a correction data set and the single-frame video data from the dynamic memory, wherein the dynamic memory stores the correction data set in advance, and the correction data set comprises multiple correction arrays correcting multiple pixel points on an LED panel; and correcting the single-frame video data according to the correction data set. Through the LED panel pixel correction method and apparatus, the problem of incapability of performing pixel correction on a large-size high-density LED panel in related arts is solved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a light emitting diode (LED) panel pixel correction method and device. Background technique [0002] The LED panel is encapsulated by a single LED lamp particle, and each LED lamp can emit light in three colors of red, green and blue, constituting a light-emitting pixel in the LED panel. Due to the differences in the particles of each LED lamp, such as differences in brightness and chromaticity, the brightness uniformity and chromaticity uniformity displayed on the entire panel are affected, thereby affecting the display quality of the image. In order to reduce the difference in the luminescence of LED lamp particles, a single-point pixel correction algorithm is introduced. Through the single-point pixel correction algorithm, the consistency of the luminance and chromaticity of each LED lamp particle is improved. Due to the large pixel pitch of the traditional LED display module,...
