Embodiment approach

[0107] It should be noted that, in the specific implementation process, when the above step S303 is performed, only the brightness value of the W sub-pixel of the first type of pixel can be modified, while the brightness value of the W sub-pixel of the second type of pixel can remain unchanged. That is to say, the brightness value of the W sub-pixel after modification of the second type of pixel is equal to the brightness value of the W sub-pixel before modification. In this implementation manner, it is also possible to improve the occurrence of stroke breaks and unclear display of characters, avoid the problem of graininess in the display screen, and improve the display effect of the display panel.

[0108] As an optional implementation, in the embodiment of the present application, the brightness value of white light obtained by mixing the modified W sub-pixel luminance value of the first type of pixel with the R, G, and B sub-pixels of the first type of pixel The value rang...

Abstract

The embodiment of the invention provides a display method and a display device of a display panel. The display method and the display device are used for solving the technical problem that an RGBW display panel in the prior art is poor in display effect. The method comprises the following steps: determining an R sub-pixel brightness value, a G sub-pixel brightness value, a B sub-pixel brightness value and a W sub-pixel brightness value of each pixel in a to-be-displayed picture; modifying a W sub-pixel brightness value of a first type of pixels to enable the modified W sub-pixel brightness value of the first type of pixels to be smaller than a W sub-pixel brightness value before modification, and obtaining a final brightness value of the first type of pixels, the first type of pixels beingpixels in a character display area in a to-be-displayed picture; and driving pixel units corresponding to the first type of pixels in a display screen to shine by adopting the driving voltage corresponding to the final brightness value of the first type of pixels.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a display method and a display device of a display panel. Background technique [0002] Currently, in order to increase the display brightness of liquid crystal display panels (Liquid Crystal Display, LCD), organic light emitting diodes (Organic Light Emitting Diode, OLED) and other display panels, white (White, W ) sub-pixel units, and four color sub-pixel units of red (Red, R), green (Green, G), blue (Blue, B) and W are formed in one pixel unit. Generally, such a display panel including sub-pixel units of four colors of R, G, B, and W is called an RGBW display panel. [0003] The addition of the W sub-pixel unit increases the difference between the pixel units of the display panel, resulting in a problem of graininess in the display screen. In particular, when a display panel with a low pixel density (Pixels Per Inch, PPI) displays a picture containing text,...
