Embodiment Construction

[0034] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0035] see Figure 4 , the present invention firstly provides a pixel structure, including a plurality of pixel units arranged in an array, and each pixel unit includes: a red sub-pixel R, a green sub-pixel B, a first blue sub-pixel B 1 , and the second blue sub-pixel B 2 . The first blue sub-pixel B 1 has a chromaticity different from that of the second blue subpixel B 2 chromaticity, the first blue subpixel B 1 with the second blue subpixel B 2 Corresponding to different blue light bands.

[0036] Specifically, the first blue sub-pixel B 1 Corresponding to the blue light band with a wavelength between 400nm and 460nm, the second blue sub-pixel B 2 Corresponds to the blue light band with a wavelength between 440 and 500nm. The first ...

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...
