Abstract

The invention provides a method, a device and equipment for color compensation. The method comprises the following steps of obtaining existing current information of a light emitting source in a screen; determining compensation data of a component R, compensation data of a component B and compensation data of a component G of a pixel corresponding to the existing current information; according to the determined compensation data of the component R, component G and component B, respectively adjusting the component R, component G and component B, so as to compensate the display color of the screen. The method has the advantages that the display effect of the screen at different current is improved, and the defect of deviation of screen color along with the current change of the light emitting source is overcome.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a color compensation method, device and equipment. Background technique [0002] With the development of science and technology, electronic devices with display screens are more and more favored by users. For liquid crystal display (Liquid Crystal Display, LCD) screens, the liquid crystal display panel itself does not emit light, and light is often transmitted through the liquid crystal display panel through a backlight source to realize information display. Since LEDs (Light-Emitting Diodes, light-emitting diodes) have the advantages of long life, wide color gamut, environmental protection and energy saving, etc., LEDs are often used as backlight sources (backlights). For Organic Light-Emitting Diode (UIV OLED) display screens, OLED display technology has the advantage of self-illumination, OLED display screens do not require a backlight source, and RGB color signals...
