Description

Method for color coordinate offset compensation
Technical Field
The invention relates to the technical field of display, in particular to a method for compensating color coordinate offset.
Background
Liquid Crystal Display (LCD) panels have the characteristics of good brightness, high contrast, strong layering, bright color, light weight, and are widely used in display products such as mobile phones, tablet computers, notebook computers, and televisions. Most of the liquid crystal displays are backlight liquid crystal displays, which are composed of a liquid crystal display panel and a backlight module.
An Organic Light Emitting Diode (OLED) display panel has many advantages of self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, a viewing angle of approximately 180 degrees, a wide range of use temperature, and capability of realizing flexible display and large-area full-color display, and is considered as a display panel with the most potential development in the industry. The OLED display panel may be divided into two categories, i.e., a Passive Matrix OLED (PMOLED) and an Active Matrix OLED (AMOLED), according to a driving manner, wherein the AMOLED display panel has pixels arranged in an array, belongs to an Active display type, and has high luminous efficacy.
Liquid crystal display panels (LCDs) and Organic Light Emitting Diode (OLED) display panels each have a plurality of pixels arranged in a matrix form. A conventional pixel generally includes three sub-pixels of Red (R), Green (G) and Blue (B), each of which is controlled by a corresponding Thin Film Transistor (TFT). In the development of the flat panel display industry, the problem of energy consumption is always concerned; people begin to spread out from the thinking that traditional RGB sub-pixels constitute a complete pixel; now subpixel arrangements such as RGBG, RGBY, RGBW, etc. gradually appear; the RGBW arrangement is particularly obvious in the aspect of reducing energy consumption, and the efficiency of products can be greatly improved theoretically. However, the RGBW arrangement method also has the corresponding disadvantages: the W sub-pixel itself has color shift. Fig. 1 is a schematic diagram of a conventional RGB sub-pixel arrangement converted into an RGBW sub-pixel arrangement, wherein the W sub-pixel has color cast.

and S205, combining the compensation coefficient to obtain an RGBW data signal subjected to preliminary compensation.
In step S202, the color coordinates of the R, G, B, W sub-pixels are respectively converted into corresponding normalized tristimulus values by using the following formulas:
the actual sub-pixel normalized tristimulus values (RX, RY, RZ), (GX, GY, GZ), (BX, BY, BZ), (WX, WY, WZ), and the target white normalized tristimulus values (DX, DY, DZ) are obtained using the above equations.

Rc＝Ri*a0，
Gc＝Gi*b0，
Bc＝Bi*c0，
Wc＝Wod0, wherein at least one of a0, b0 and c0 is 0.
