Embodiment Construction

[0019] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0020] A liquid crystal display is mainly composed of a backlight, a liquid crystal panel and a driving circuit. The LCD panel itself does not emit light, and needs to rely on the light source provided by the backlight to achieve brightness display.

[0021] The imaging principle of the liquid crystal display is to place the liquid crystal between tw...

Abstract

Embodiments of the present application provide a display device and a display method thereof. The display device includes a display panel, an azimuth sensor for acquiring a viewing angle α of a target person relative to the display device, and a viewing angle α that is configured to receive the viewing angle α sent by the azimuth sensor. And compare the viewing angle α with the preset angle threshold to turn on or off the processor for improving the viewing angle of the display panel, so that when the target person looks directly at the display device, it avoids obvious grains of the image and visible jagged edges At the same time, it does not affect the improvement of the viewing angle when the user looks sideways, which can meet the actual application needs of the user and realize the dynamic balance between the loss of image quality and the viewing angle experience.

Description

technical field [0001] The embodiments of the present application relate to the field of display technology, and in particular, to a display device and a display method thereof. Background technique [0002] With the continuous development of science and technology, display technology has been developed rapidly, and the penetration rate of display devices is getting higher and higher. At the same time, people's requirements for display devices are also getting higher and higher. [0003] In the related art, the panel of the display device adopts a viewing angle improvement algorithm (Advance low colorwashout, referred to as ALCW) to improve the viewing angle. For example, the pixels are divided into main and sub, and different gamma values ​​are applied to the main and sub, using The overall effect after superimposition is to fit the normal gamma when viewing from the front, and display the image, thereby reducing the degree of whitening of the image when the user looks side...
