The invention provides a compensation method of a display panel, the display panel and a display device. The method comprises the following steps: establishing a gray-scale value brightness mapping rule between an m-bit gray scale and an n-bit gray scale, wherein the gray-scale value brightness mapping rule comprises a brightness corresponding relation between an m-bit gray scale and an n-bit grayscale; wherein m bits are data bit widths corresponding to preset image data of single-color pixels in the display panel, the n-bit gray scale comprises 2n gray scale values, the m-bit gray scale comprises 2m gray scale values, the maximum brightness corresponding to the m-bit gray scale is the same as the maximum brightness corresponding to the n-bit gray scale, m and n are positive integers, and m is smaller than n; obtaining preset image data; determining a first gray scale value in m-bit gray scales corresponding to the preset image data; determining a second gray-scale value in the n-bitgray scale corresponding to the preset image data according to a gray-scale value brightness mapping rule; compensating a second gray scale value in the n-bit gray scale; and lightening the monochrome pixel according to the second gray scale value in the compensated n-bit gray scale.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to a compensation method for a display panel, a display panel and a display device. 【Background technique】 [0002] Organic Light Emitting Diode (OLED) is recognized by the industry as the successor to LCD due to its thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, and high and low temperature resistance. The third generation display technology after the display panel (Liquid Crystal Display, LCD). [0003] Figure 1A It is a structural schematic diagram of a display panel in the prior art; Figure 1B It is a schematic diagram of a screen of a display panel in the prior art. [0004] Such as Figure 1A , 1B As shown, in the prior art, the display panel P includes red pixels R, green pixels G, and blue pixels B in multiple rows and columns. A red pixel R, a green pixel G, or a blue pixel B is disp...
