Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0057]Existing OLED display panels are prone to luminance deviations, resulting in poor display effects of the OLED display panels. In the compensation method of the prior art, the compensation gray scale corresponding to multiple gray scales is usually stored in the display panel, and the interpolation operation is performed according to the stored compensation gray scale when the display panel displays the picture, and the compensation gray scale of each gray scale is obtained. brightness compensation in graysca...

Abstract

The embodiment of the invention discloses a compensation method, device and system of a display panel. The compensation method of the display panel comprises the following steps: determining compensation gray scales corresponding to a plurality of different display gray scales of sub-pixels, wherein the display panel comprises a plurality of sub-pixels; establishing a fitting function between the display gray scales and the compensation gray scales according to the plurality of display gray scales and the compensation gray scales; performing partial differential processing on the fitting function to determine a solution formula of each coefficient of the fitting function; determining a coefficient of the fitting function by adopting an iterative algorithm according to the solution formula and a set precision value; and storing the determined fitting function in a display panel, so that the display panel compensates each sub-pixel according to the fitting function. According to the scheme of the embodiment of the invention, the compensation precision of the display panel is improved, and the brightness deviation is reduced, so that the display effect of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to a compensation method, device and system for a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panel is a self-illuminating display panel. Compared with liquid crystal display panel (liquid crystal display, LCD), OLED display panel does not require a backlight source, so OLED display panel is lighter and thinner In addition, OLED display panels also have the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and are increasingly used in various high-performance display fields. [0003] However, the existing OLED display panels are prone to luminance deviations, resulting in poor display effects of the OLED display panels. Contents of the invention [0004] The present invention provides a compensation method, device and system for a display p...
