Problems solved by technology

However, since the diffuse reflection screen is still used, the rough surface of the screen reflects the laser light to the audience's eyes more uniformly. Laser speckle phenomenon, so projection display type VR eyes cannot obtain high resolution in principle, which can no longer meet the needs of customers
At present, the resolution of VR glasses is required to reach above 4K, so the early projection display VR glasses have been replaced by organic light-emitting diode (OLED) display, but OLED technology has a high threshold, low yield rate, limited service life, and low price. stay high

Embodiment 1

[0042] This embodiment provides a high-resolution fluorescent display screen and a manufacturing method thereof.

[0043] A high-resolution fluorescent display:

[0044] Such as figure 1 As shown, the high-resolution fluorescent display screen in this embodiment consists of a substrate (1), a red fluorescent material layer (2), a first isolation layer (3), a green fluorescent material layer (4), a second isolation layer (5) , the blue fluorescent material layer (6) and the protective layer (7) are sequentially stacked.

[0045] The substrate is made of glass;

[0046] The structural formula of the material of the red fluorescent material layer is as follows:

[0047]

[0048] The structural formula of the material of the green fluorescent material layer is as follows:

[0049]

[0050] The structural formula of the material of the blue fluorescent material layer is as follows:

[0051]

[0052] Among them, R is C 8 h 17 ;

[0053] The material of the first iso...

Embodiment 2

[0060] This embodiment provides a high-resolution fluorescent display screen and a manufacturing method thereof.

[0061] The structure and preparation method of the high-resolution fluorescent display screen in this embodiment are the same as those in Embodiment 1, the difference lies in the materials of the fluorescent material layer and the isolation layer, and the curing process of each layer.

[0062] Wherein, the material of the fluorescent material layer is a small molecule fluorescent material, specifically as follows:

[0063] The red fluorescent material adopts rhodamine series alcohol-soluble dyes, and the red fluorescent material is dispersed in the heat-crosslinkable acrylic alcohol solution during spin coating. After spin coating, it was cured at 120°C for 10 minutes.

[0064] The green fluorescent material adopts coumarin dye, and the green fluorescent material is dispersed in the heat-crosslinkable polyurethane prepolymer during spin coating. After spin coati...

Embodiment 3

[0068] This embodiment provides a high-resolution fluorescent display screen and a manufacturing method thereof.

[0069] The structure and composition of the high-resolution fluorescent display screen in this embodiment are the same as those in Embodiment 1, the difference is that each layer is prepared by a film-forming method by pulling.

Abstract

The invention belongs to the technical field of preparation of a display screen, and particularly relates to a high-resolution 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 layerand a protection layer which are sequentially overlaid; and arrangement of the isolation layers enable fluorescent materials not to interfere each other. The display screen is made of a super-flat transparent material, and can avoid a problem of diffuse reflection caused by a conventional rough surface; moreover, the fluorescent materials have anisotropism and do not generate interference, and thus, a mirror reflection phenomenon can be avoided; and when laser is used as a light source, resolution can reach 10k. The display screen is simple in preparation method, low in cost, reliable in technology and long in service life. The high-resolution fluorescent display screen can be used for VR and small-medium-size high-resolution display. The high-resolution fluorescent display screen is lightweight, can be folded and unfolded, is waterproof, does not need to be driven by electric power and is economic and durable, and thus, the high-resolution fluorescent display screen can be applied invarious fields.

Description

technical field [0001] The invention belongs to the technical field of display screen preparation, and in particular relates to a high-resolution fluorescent display screen and its preparation method and application. Background technique [0002] 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. The advantages of projection display are large display area, small projector size, light weight, simple operation, and low cost. The disadvantage is that the light utilization rate is low, and it is difficult to use under strong light conditions; The principle of diffuse reflection is used. Laser projectors are currently on the market, and lasers effectively increase the resolution of images. Especially with the rise of VR technology, laser projectors have been applied in wearable devices such as head displays...
