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

Embodiments of the present application provide a display method and a display device for a display panel, which are used to solve the technical problem of poor display effect of an RGBW display panel in the prior art. The method includes: determining the R sub-pixel brightness value, the G sub-pixel brightness value, the B sub-pixel brightness value and the W sub-pixel brightness value of each pixel in the image to be displayed; modifying the W sub-pixel brightness value of the first type of pixels, so that all The modified W sub-pixel luminance value of the first type of pixel is smaller than the W sub-pixel luminance value before modification, and the final brightness value of the first type of pixel is obtained, wherein the first type of pixel is the text in the picture to be displayed Pixels in the display area: using the driving voltage corresponding to the final brightness value of the first type of pixels to drive the pixel units corresponding to the first type of pixels in the display screen to light up.

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,...
