Embodiment 1

[0024] The method for preparing a multi-domain display panel includes the following steps:

[0025] S1. Coating a layer of polyimide (PI) film 1 on the first substrate (array substrate) covered by ITO on the top layer, and at the same time, coating a layer on the second substrate (color filter substrate) covered by ITO on the top layer Polyimide (PI) film 1; then pre-baked at 80°C for 3min;

[0026] S2. Utilize patterned mask 2 to block, divide into irradiation area 4 and shielding area 3; use low-illuminance UV light (4-10mw / cm 2 ) to irradiate PI film 1, the ultraviolet light intensity is , and the irradiation time is about 5 minutes; in the irradiation area 4 (the part not covered by the mask 2), the polyimide will decompose under the irradiation of ultraviolet light, thereby reducing the alignment of the irradiation area 4 The surface anchoring energy of the membrane;

[0027] S3. Heat the alignment film on the irradiated first substrate and the second substrate to cure ...

Abstract

The invention discloses a method for preparing a display panel. The method includes the following steps that S1, a first substrate and a second substrate are coated with alignment films respectively, and the alignment films are preheated; S2, the first substrate and the second substrate coated with the alignment films are each divided into an irradiation region and a shielding region; the first substrate and the second substrate coated with the alignment films are irradiated by ultraviolet light, and polymers in the alignment films in the irradiation regions are degraded; S3, the alignment films on the irradiated first substrate and second substrate are heated, and the alignment films are cured; S4, the cured alignment films on the first substrate and the second substrate are subjected to directional friction treatment, and grooves are formed; S5, the first substrate and the second substrate obtained after directional friction treatment are paired, liquid crystal molecules are injected, a liquid crystal box is formed, and finally the display panel is prepared. The display panel can achieve multi-domain display.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and relates to a method for preparing a display panel and the prepared display panel. Background technique [0002] Currently, the two most commonly used display modes of liquid crystal display devices are vertical alignment (VA) mode and in-plane switching (IPS) mode. VA display has become a common display mode for large-size TV TFT-LCDs due to its advantages of high contrast and no need for frictional alignment. As a common feature of VA display, the phenomenon of color shift under different viewing angles is a major issue that VA product design must face. The so-called color shift means that when the same display panel displays the same color, the brightness and color seen at different viewing angles will also be different. In order to solve the problem of color shift under different viewing angles, people have developed the MVA technology that implants protrusions on the alignment film...
