Description

Technical Field

[0001] This utility model relates to the field of full-view VA technology, and in particular to a full-view VA display and a device with display function. Background Technology

[0002] Full-view VA displays are popular among users due to their high contrast ratio and wide viewing angle, and are widely used in the market. However, full-view VA displays also have high costs. In addition to the high costs of liquid crystal, PI, and mold making, the cost of polarizers is also quite high. At present, full-view VA displays on the market basically follow the application principle of "polarizer optical axis of 45° and -45°". However, due to the special design of full-view VA, simply changing the angle of the polarizer cannot achieve a high degree of matching with liquid crystal molecules, and cannot achieve efficient use of light, resulting in complete failure of display brightness and viewing angle, and reducing the utilization rate of polarizers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a novel design for a full-view VA display and a device with display functions, so as to reduce manufacturing costs and improve the light utilization rate of the first polarizer and the second polarizer.

[0004] The technical solution of this utility model for a full-view VA display is as follows:

[0005] It includes a first polarizer, a first ITO layer, a second ITO layer, and a second polarizer that are stacked in sequence;

[0006] Multiple parallel first trenches are opened on the first ITO layer, and multiple parallel second trenches are opened on the second ITO layer. Each first trench is parallel to each other, and the first trenches and second trenches are arranged alternately.

[0007] The angle between each first trench and the target line is 45°, and the angle between each second trench and the boundary line of the target line is 45°.

[0008] The optical axis of the first polarizer is at an angle of 0° to the preset plane, and the optical axis of the second polarizer is at an angle of 90° to the preset plane; or, the optical axis of the first polarizer is at an angle of 90° to the preset plane, and the optical axis of the second polarizer is at an angle of 0° to the preset plane.

After the first ITO layer and the second ITO layer are integrated, the first trenches and the second trenches are arranged alternately, and the angle between the optical axis of the first polarizer and the preset plane and the angle between the optical axis of the second polarizer and the preset plane are changed from 45° and -45° to 0° and 90°. Specifically, the angle between the optical axis of the first polarizer and the preset plane is 0°, and the angle between the optical axis of the second polarizer and the preset plane is 90°, or the angle between the optical axis of the first polarizer and the preset plane is 90°, and the angle between the optical axis of the second polarizer and the preset plane is 0°. Then, after energizing, the angle between the tilt direction of the liquid crystal molecules and the preset plane is 45°, which can effectively improve the light utilization rate of the first polarizer and the second polarizer.
