A pixel structure, its driving method and display device

Abstract

The invention discloses a pixel structure, a driving method thereof and a display device. The pixel structure comprises: a plurality of closely arranged repeating groups; the repeating groups are composed of linearly arranged RGB square pixel units; each square pixel unit is composed of two Composed of sub-pixels of the same color and shape, the two sub-pixels of adjacent square pixel units are arranged in different ways; the positions of each repeated group on two parallel and adjacent straight lines are staggered by a half-square pixel unit, In this way, the brightness of the input information is redistributed and output to the corresponding actual physical position. For example, when a white pixel is displayed, the control pixel structure displays three adjacent RGB squares at the position of the square pixel unit that displays the white pixel. All sub-pixels in the pixel unit or three adjacent RGB sub-pixels are turned on to display white pixels, and the resolution of the displayed image is improved by selectively turning on the sub-pixels without reducing the pixel size.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure, its driving method and a display device. Background technique [0002] At present, the common pixel design of the display screen is RGB or RGBW design, that is, a pixel is composed of three sub-pixels or four sub-pixels for display, and its visual resolution is the physical resolution. However, with the increase of customers' requirements on display experience, panel manufacturers need to continuously increase the visual resolution (PPI) design of the display. At present, the physical resolution of the display screen is generally improved by reducing the pixel size. However, as the size of the pixel becomes smaller and smaller, the process of manufacturing the display screen will become more and more difficult, especially in the process of manufacturing the organic light emitting (Organic Light Emitting Diode, OLED) display screen, the difficulty of t...
