Pixel structure and high-brightness wide-color-gamut long-life display method

Abstract

The invention provides a pixel structure and a high-brightness wide-color-gamut long-life display method. The pixel structure comprises a plurality of pixel units which are arranged in an array type. Each pixel unit comprises a red sub-pixel (R), a green sub-pixel (G), a first blue sub-pixel (B1) and a second blue sub-pixel (B2). A chroma of the first blue sub-pixel (B1) is different from a chroma of the second blue sub-pixel (B2). The chroma of the first blue sub-pixel (B1) and the second blue sub-pixel (B2) correspond to different blue bands. By using the display method, according to the color gamut and the brightness needed by actual display, lightening or closing of the first blue sub-pixel (B1) and lightening or closing of the second blue sub-pixel (B2) are selected. Effects of increasing display brightness, expanding the color gamut and prolonging a blue sub-pixel life are reached.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure and a display method with high brightness, wide color gamut and long service life. Background technique [0002] Flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Display (OLED) all include a plurality of pixels arranged in an array, and each pixel usually includes red, green, The sub-pixels of three colors of blue, each sub-pixel is controlled by a gate line and a data line, the gate line is used to control the opening and closing of the sub-pixel, and the data line applies different data voltage signals to the sub-pixel, Make the sub-pixels display different gray scales, so as to realize the display of full-color images. [0003] With the development of display technology, people are pursuing higher and higher display quality of display devices such as display brightness, color reproduction, and richness of screen col...

Problems solved by technology

[0008] However, the above three methods have their own shortcomings: figure 1 Although the shown RGBW pixel structure can increase the display brightness, it also deteriorates the color gamut; figure 2 Although the shown RGBY pixel structure effectively expands the color gamut, its blue sub-pixel B has the problems of insufficient brightness and short life; image 3 RGB shown b Although the pixel structure can increase the brightness of the blue sub-pixel and prolong the life of the blue sub-pixel, it cannot expand the color gamut. At the same time, the large-area dark blue sub-pixel B b Difficult to make
