Problems solved by technology

[0005] In the driving process of the above-mentioned display panel, the timing of pixel input data, HRA processing data and pixel output data is separated. The register requirements are very high, and the register needs to have the ability to cache a large amount of pixel data information (several lines of pixel data or even several frames of pixel data) at the same time, which increases the capacity of the driver IC, and the power consumption of the driver IC also increases accordingly. The cost increases, which increases the delay of pixel output data (the pixel clock cycle delay of several lines to several frames)

Embodiment 1

[0035] This embodiment provides a display panel driving method and a display panel.

[0036] Wherein, the display panel includes a plurality of pixel structures arranged in an M*N matrix. In the display panel driving method, the display panel is driven cyclically by a driving group composed of adjacent i row / column pixel structures; in any driving group , the pixel data of adjacent two row / column pixel structures are output with a difference of one clock cycle in sequence, this driving method is used to realize the image display of pixel data with K*L resolution, wherein, K≥M or L≥N, i is positive integer multiple of 4.

[0037] In the display panel, the clock period is a very important timing signal, and the time interval between adjacent pixel clock signals is the clock period. The frequency of the pixel clock signal is related to the working mode of the display panel. The higher the resolution of the display panel, the higher the frequency of the pixel clock signal. In a ...

Embodiment 2

[0095] This embodiment provides a display device, including the display panel of Embodiment 1.

[0096] The display device can be any product or component with a display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0097] The display device adopts the display panel in Embodiment 1, because the display panel has a lower cost of the driver IC, and has a smaller delay in displaying images; correspondingly, the display device has a lower cost, and The real-time display effect is better.

Abstract

The invention belongs to the field of display techniques, and particularly relates to a display panel driving method as well as a display panel and a display device. According to the display panel driving method, the display panel comprises a plurality of pixel structures which are arrayed in an M*N matrix mode, and is driven by driving groups formed by pixel structures of adjacent i rows / columns in a circulating manner; in any driving group, pixel data of the pixel structures of each two adjacent rows / columns are sequentially output with the interval of a clock period; the driving method is used for achieving image display of the pixel data with a K*L resolution ratio, wherein K is more than or equal to M or L is more than or equal to N, and i refers to a positive integer multiple of 4. The driving method has a low requirement on the storage capability of a register; the time delay of display images is low; the real-time display effect is superior.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel driving method, a display panel, and a display device. Background technique [0002] In the existing flat panel display device, the structure of the display panel usually includes a plurality of pixel structures, and each pixel structure includes red, green and blue (RGB) three-primary color sub-pixel structures, and the color adjustment of each sub-pixel structure realizes the pixel structure as a whole. The grayscale adjustment of the structure, so as to realize the display of color images. Correspondingly, the software algorithm of the display panel is: buffer the RGB sub-pixel image data (including color components) of all pixels in a row into registers respectively, calculate the RGB sub-pixel data required for display and store them in the buffer register, and then The RGB sub-pixel data is output through the display driver module (that is, the...
