Display screen and virtual reality helmet

Abstract

The invention relates to the technical field of virtual reality, in particular to a display screen and a virtual reality helmet. The display screen includes a pixel matrix used for illuminating display and light shielding layers used for preventing mutual crosstalk of colored light between pixel units in the pixel matrix, light-emitting surfaces of the pixel matrix are provided with diffusion films used for weakening optical performance of the light-shielding layers, each diffusion film is of a mesh structure and is composed of a plurality of grid units, and at least one grid unit is disposedon the corresponding light-emitting surface of each pixel unit. Compared with the prior art, the provided display screen has the advantages of being simple in structure, convenient to use, low in production cost and the like, and can provide a better display effect.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a display screen and a virtual reality helmet. Background technique [0002] The LCD screen is based on the principle of transmissive imaging. The liquid crystal itself does not emit light. All the light comes from the light source behind the liquid crystal panel. The liquid crystal molecules have the unique function of changing the original direction of the light. When the light passes through, the intensity of the light can be controlled through the liquid crystal layer. . Since the liquid crystal itself has no color, people add a layer of color filter film in the direction where the liquid crystal is emitted. There are many red, green and blue primary color pixels on the film. Light is controlled by liquid crystal molecules, and the intensity of light passing through each pixel unit is also different. The three primary colors are mixed to get the color we need. [00...

Problems solved by technology

However, since the head-mounted display is relatively close to the human eye, and the picture usually needs to be enlarged by the optical system before entering the human eye, the light-shielding layer between the pixels of the display screen with conventional pixel density is easy to show, so that the display observed by the human eye The image is more grainy

[0005] In order to improve the grain effect of the display screen of the head-mounted display, the usual method is to increase the pixel density of the display panel of the display, but increasing the pixel density will increase the complexity and cost of the display screen manufacturing process
