Problems solved by technology

However, this design also has disadvantages: because the common electrodes of two adjacent pixels need to be connected by depositing a metal layer, and the deposited metal layer just corresponds to the position of the blue pixel, which leads to the gap ratio between different pixels. Inconsistency, resulting in color cast

Embodiment Construction

[0012] The present invention provides a display substrate, such as figure 1 As shown, the display substrate includes: a substrate 1, a black matrix 2, a color filter layer, and a transparent conductive layer 6; the color filter layer includes red pixels 3, green pixels 4, and blue pixels 5; wherein, the blue pixels 5 Doped with D-π-A structure dye molecules 7.

[0013] Another embodiment of the present invention provides another display substrate, that is, an array substrate formed by COA (Color Filteron Array) technology, that is, a color filter layer is formed on the array substrate. In an array substrate based on COA technology, the blue pixels of the color filter layer are doped with D-π-A structural dye molecules.

[0014] The display substrate provided by the present invention is applied to liquid crystal displays, OLED displays and the like.

[0015] The principle of D-π-A structure dye molecules for chromaticity compensation is explained below.

Abstract

The invention discloses a display substrate which comprises a color film; the color film contains red pixels, a green pixel and a blue pixel, wherein D-Phi-A structure dye molecules are doped in the blue pixels. With the adoption of the display substrate, a certain degree of color error compensation can be realized.

Description

Technical field [0001] The present invention relates to the field of display, in particular to a display substrate and a display device. Background technique [0002] Matrix-Vcom is a relatively common array design, which can increase the uniformity of the common voltage (Vcom) and reduce the occurrence of greenish. However, this design also has drawbacks: the metal layer is deposited to connect the common electrodes of two adjacent pixels, and the deposited metal layer corresponds to the position of the blue pixel, which leads to the aperture ratio between different pixels. Inconsistent, eventually produce color cast. Summary of the invention [0003] In view of this, the main purpose of the present invention is to provide a display substrate and a display device, which can compensate for the color shift phenomenon in the display device. [0004] In order to achieve the above objective, the technical solution of the present invention is achieved as follows: [0005] A display subs...
