Abstract

The invention provides a color compensation method and display device and the method comprises the steps: determining the offset of a color coordinate according to the change of a color coordinate influence factor and a preset first corresponding relation; wherein the color coordinate influence factors comprise at least one of the following factors: the temperature of the display device, backlightdriving current and color temperature; wherein the first corresponding relationship comprises a corresponding relationship between the change of the color coordinate influence factor and the offset of the color coordinate; determining a color compensation value according to the offset of the color coordinate, wherein the offset of the color coordinate comprises the initial offset of the x coordinate and the initial offset of the y coordinate; and compensating the color of the display device according to the color compensation value. According to the method provided by the embodiment of the invention, color compensation is carried out after the color coordinates of the display equipment deviate.

Description

technical field [0001] The invention relates to the technical field of display processing, in particular to a color compensation method and a display device. Background technique [0002] Since the excited emission wavelength of the quantum dot is only related to the energy level structure of the quantum dot (the size of the quantum dot), the half-wave width of the emitted wavelength is very narrow, and the luminous purity is very high. The display device using the quantum dot light-emitting material has a high color gamut, so quantum dot display devices have been widely used. [0003] In related technologies, in a quantum dot display device, when there is a local backlight partition control function, for a local area, when the driving current of the LED backlight and the temperature of the local area change, the excitation current of the quantum dot luminescent material changes, The color coordinates of the display device will change accordingly, resulting in a large shift...
