Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0036] In the liquid crystal display panel, an electrode layer (ITO electrode layer) is added on the first substrate, and an alignment voltage is applied to the electrode layer during the liquid crystal alignment process, so that in the same domain area of ​​the sub-pixel, the corresponding branch electrodes There is a difference between the pretilt angle of the liquid crystal molecules in the liquid crystal layer and the pretilt angle of the liquid crystal molecule...

Abstract

The invention relates to a liquid crystal display panel, a liquid crystal alignment method and a mobile terminal. The liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer, a common electrode, a pixel layer and an electrode layer. In the liquid crystal alignment process, the electrode layer receives alignment voltage, and the pretilt angle of the liquid crystal molecules arranged opposite to the branch electrodes is smaller than that of the liquid crystal molecules arranged opposite to the slits. In the actual driving process of the liquid crystal display panel, due to the fact that the pretilt angles of the liquid crystal molecules in the liquid crystal layer are integrally increased and differentiation of the pretilt angles in the same domain of the sub-pixels is achieved, the response time of the liquid crystal display panel can be prolonged, and the viewing angle characteristics of medium and low gray scales can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel, a liquid crystal alignment method and a mobile terminal. Background technique [0002] Large-size TFT-LCD (Thin Film Transistor Liquid Crystal Display) is the mainstream technology used in TVs at present. With the continuous improvement of information technology and living standards, people have higher and higher requirements for display quality such as response time and viewing angle. In addition, compared with IPS-LCD (In-Plane Switching, IPS, In-Plane Switching, in-plane switching) and OLED displays, VA-LCD (Vertical Alignment Liquid Crystal Display) has a poor viewing angle. Therefore, the improvement of the viewing angle has been the focus of VA-LCD researchers. According to the principle of through liquid crystal alignment and the driving scheme, in order to improve the viewing angle, it is necessary to divide the pixel into multiple domain...
