Array substrate and display

Abstract

The invention discloses a display, which comprises a first substrate, a transistor array substrate and a shading layer, wherein the first substrate comprises a first electrode; the transistor array substrate comprises a plurality of pixels which are arranged in an array; each pixel comprises a transistor and a pixel electrode which is electrically connected with the transistor; a display medium is positioned between the first electrode and the pixel electrode; and the shading layer is positioned between the first substrate and the transistor. In the display, the shading layer can protect the transistor from generating light leakage current, so that displaying quality is enhanced.

Description

technical field [0001] The present invention relates to a display device, in particular to a high-contrast display. Background technique [0002] Figure 1A is a schematic top view of the cell structure in the above-mentioned conventional electrophoretic display, and Figure 1B for Figure 1A A partially enlarged perspective view of an existing electrophoretic display. Please refer to Figure 1A and Figure 1B , the material of the partition wall structure 130 in the conventional electrophoretic display 100 is a transparent material, and the display medium 140 filled in the microcellular structure 150 is composed of a black fluid 140b and a plurality of white particles 140a dispersed in the black fluid 140b constitute. like Figure 1B As shown, when the electric field between the pixel electrode 122 on the transistor array substrate 120 and the common electrode 112 on the electrophoretic substrate 110 changes, the white particles 140a will move up or down relative to the...

Problems solved by technology

In this way, since the partition wall structure 130 is made of a transparent material, the light L passing through the transparent partition wall structure 130 will be incident on the transistor array substrate 120, which will cause light leakage and reflection of each metal film layer in the transistor array substrate, thereby reducing the display contrast. And the transistor 124 within its projection range will cause the carriers in the channel region of the transistor 124 to absorb the energy of the light L to generate a leakage current, resulting in abnormal screen display

If it is more serious, the instantaneous large leakage current will cause the data line electrically connected to it to be burned, resulting in line defects. Therefore, the existing electrophoretic display has the disadvantage that the transistor is susceptible to leakage current due to the influence of ambient light

[0004] From the above, it can be seen that the existing electrophoretic display cannot avoid the problems of leakage and reflection of external light and the leakage current of transistors affected by external light.
