Embodiment Construction

[0032] The embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] For the OLED display panel, the pixel unit includes a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B. Among them, the OLED display panel uses OLED elements as sub-pixels for image display. In order to improve the display effect, pixel rendering is generally used for display driving. Adjacent pixel units have shared sub-pixels, the driving circuit is in a row, and RGBG is alternately arranged, so the display brightness of RGB cannot...

Abstract

The invention discloses a display driving method, a display driver and a display device, and the method can select an adaptive compensation mode based on the to-be-displayed gray scale of a to-be-displayed sub-pixel, so as to provide a data voltage for the to-be-displayed sub-pixel. The compensation mode comprises a first compensation mode and a second compensation mode; if the to-be-displayed gray scale is 0 gray scale, selecting a first compensation mode, and if the to-be-displayed gray scale is greater than 0 gray scale, selecting a second compensation mode; wherein the first compensation mode is used for reducing the difference value of the light emitting efficiency of the sub-pixels with different light emitting colors under the same gray scale. According to the invention, display compensation can be carried out on the to-be-displayed sub-pixel at the zero gray scale in the first compensation mode, and display compensation can also be carried out on the to-be-displayed sub-pixel at the non-zero gray scale greater than the zero gray scale in the second compensation mode; the problem of display color cast caused by different light-emitting efficiency attenuation speeds when sub-pixels with different light-emitting colors are in low gray scales can be solved.

Description

technical field [0001] The present application relates to the technical field of image display, and more particularly, to a display driving method, a display driver and a display device. Background technique [0002] With the continuous development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable and important part of today's people. tool. [0003] The main component of the display device to realize the display function is the display panel. OLED (Organic Light Emitting Diode) display panels display images through OLED elements with self-luminous function, and have the advantages of no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, and wide operating temperature range. , simple structure and process, and many other excellent characteristics, become one of the current mai...
