Embodiment Construction

[0084] figure 1 Shows the sub-pixel arrangement structure of the existing color display device, such as figure 1 As shown, the adjacent blue sub-pixels B and red sub-pixels R in the same row are alternately arranged, and the adjacent blue sub-pixels and red sub-pixels in the same column are alternately arranged to form red and blue sub-pixel columns. A green sub-pixel column is arranged between the red and blue sub-pixel columns, and each green sub-pixel G of the green sub-pixel column and each sub-pixel (blue sub-pixel B or red sub-pixel R) in the red and blue sub-pixel column are on the row side Staggered upwards. For this sub-pixel arrangement structure, through the dislocation arrangement of the red sub-pixel R and the blue sub-pixel B, the sub-pixel color can be borrowed in color display, and the sub-pixel color can be reduced without compromising the definition of the display panel. The overall number of pixels, so as to achieve the purpose of developing higher resolut...

Abstract

The invention discloses a monochromatic display method and a monochromatic display device. The display method of one embodiment is applied to the monochromatic display device, the monochromatic display device drives sub-pixels arranged in 2N rows * 2N columns to display according to received three-primary-color image data in N rows * N columns, and the sub-pixels located in even columns and the sub-pixels located in odd columns are arranged in a staggered mode in the row direction. The method comprises the following steps: converting the three-primary-color image data into gray image data of N rows * N columns; determining a gray-scale value of each sub-pixel corresponding to a preset driving mode according to the preset driving mode and the gray image data; and driving each sub-pixel to display according to the gray-scale value of each sub-pixel. According to the method, the gray image data can be effectively restored, color image data loss in the monochrome display process is avoided, the color image data can be well restored, and the method has the advantages of being good in display effect and high in monochrome display definition.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a monochrome display method and a monochrome display device. Background technique [0002] In the prior art, the pixel arrangement of a monochrome display device is generally the same as that of a color display device. When a monochrome display device performs monochrome display, it needs to convert the received color image data into the gray scale value of each sub-pixel in the monochrome display device, and the monochrome display device further drives each sub-pixel to display according to the gray scale value. However, in the monochrome display process of the monochrome display device, the loss of color image data is prone to occur, and the color image data cannot be fully restored, resulting in poor monochrome display effect. Contents of the invention [0003] The purpose of the present invention is to provide a display panel, a manufacturing method there...
