Problems solved by technology

Display devices in the prior art usually use lens imaging to expand the viewing angle of the human eye, but the resolution of the display screen used in this display device cannot be greatly improved, resulting in a decrease in viewing angle resolution and poor image quality The phenomenon, this phenomenon is mainly manifested as the screen door effect of the black matrix (BM)
[0003] In order to solve this problem, the technical means of adding microlenses arranged in an array on the light-emitting side of the display panel is usually adopted in the prior art, so that the spot area becomes larger, thereby reducing the spacing between pixels, but the production cost of using microlenses High, it also needs to be accurately aligned with the display, the process is difficult, and the product yield rate is reduced

Abstract

The invention discloses a display device, comprising a display panel, wherein the display panel comprises a light emitting side, a birefringent structure is disposed on the light emitting side of thedisplay panel, a plane where the birefringent structure is located is parallel to the plane where the display panel is located, and when the display device is in a display phase, on the plane parallelto the birefringent structure, the birefringent structure and the display panel generate relative rotation. In the display device disclosed by the invention, by setting the relative rotation of the birefringent structure and the display panel, the light emitting area of each pixel of the display device is expanded from the vision, the screen window effect existing in the display device in the prior art is weakened, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] At present, with the development of science and technology, the design of display devices is constantly pursuing smooth user experience, and at the same time, more and more sensory experience for users, such as: wide viewing angle, high resolution, narrow frame, high screen-to-body ratio, etc. Performance becomes the selling point of each display device. Display devices in the prior art usually use lens imaging to expand the viewing angle of the human eye, but the resolution of the display screen used in this display device cannot be greatly improved, resulting in a decrease in viewing angle resolution and poor image quality This phenomenon is mainly manifested as the screen door effect of the black matrix (BM). [0003] In order to solve this problem, the technical means of adding microlenses arranged in an arra...
