Abstract

The invention relates to an image display method and device, and belongs to the technical field of electronics. The method comprises the steps: obtaining the total lighting time length of a display device, wherein the total lighting time length is the accumulated lighting time length of the display device from primary lighting; determining a first compensation voltage corresponding to the total lighting duration of the display device according to a pre-stored corresponding relation between the total lighting duration and the compensation voltage, wherein the compensation voltage comprises a compensation sub-voltage corresponding to each color channel; and adjusting the driving voltage of each pixel point based on the first compensation voltage when an image is displayed. According to the invention, the color distortion of the display image can be reduced.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to an image display method and device. Background technique [0002] With the development of electronic technology, LEDs (Light Emitting Diodes, light emitting diodes) are widely used in various fields, such as traffic lights, automobile lights, street lights, LED displays, liquid crystal displays, and the like. LED is mainly composed of chip, phosphor and shell. When the LED emits light, the chip excites blue light, and the phosphor is excited by the blue light to produce red light and green light. The three colors are mixed in different proportions to obtain different colors. This ratio can be controlled by the amount of phosphor. [0003] The liquid crystal display uses LEDs as a backlight to emit light, and the light passes through the polarizing layer, liquid crystal layer, color film layer, etc. to display images. The light emitted by the LED as a backlight is ...
