Abstract

The invention belongs to the technical field of preparation of a display screen, and particularly relates to a cross-linked fluorescent display screen and a preparation method and application thereof.The display screen comprises a substrate, a red fluorescent material layer, a first isolation layer, a green fluorescent material layer, a second isolation layer, a blue fluorescent material layer and a protection layer which are sequentially overlaid; arrangement of the isolation layers enables fluorescent materials not to be interfered mutually; and when materials of the isolation layers contain a light absorption group or a light absorption dye, high-energy laser in the front has no interference to the rear layers. The display screen is made of a super-flat transparent material; the adopted fluorescent materials have anisotropism, so that problems of diffuse reflection and specular reflection can be avoided; and particularly, the cross-linked fluorescent materials are adopted, so thatthermal stability is higher, and when laser is used as a light source, resolution reaches 10k. The display screen is simple in preparation method, low in cost, reliable in technology, long in servicelife and lightweight, can be folded and expanded, is waterproof, does not need to be driven by electricity, and is economic and durable, and thus, the display screen can be applied in various fields.

Description

technical field [0001] The invention belongs to the technical field of display screen preparation, and in particular relates to a cross-linked fluorescent display screen and a preparation method and application thereof. Background technique [0002] With the rise of VR technology, ultra-high-resolution head-mounted displays will become one of the mainstream wearable devices in the future. Projection display technology is the first choice for VR display technology due to its relatively mature and reliable products. Projection display is a method or device in which the light source is controlled by planar image information, and the image is enlarged and displayed on the projection screen by using the optical system and projection space. However, the low resolution of current projection display limits its application in high-resolution VR devices. [0003] The reason for the low resolution of the projection display is that the viewing angle of the specular reflection is very s...
