Non-grid pixel light-emitting display device and display method thereof

Abstract

The invention discloses a non-grid pixel light-emitting display device and a display method thereof. The non-grid pixel light-emitting display device comprises a display screen and a projection module. The display screen is made of a fluorescent light-emitting material, is of a grid-removing and pixelated physical structure, and can carry out composite intensity spectrum processing on projection characteristic light and emit new display characteristic light; the projection module transmits a light beam towards the display screen, the light beam has discrete characteristics of light energy in a light beam cross section parallel to the display surface, and the display screen receives the light beam and inherits the discrete characteristics. According to the technical scheme, due to the fact that grids are removed and a physical structure is pixelated, transparency is improved, the manufacturing process of the display screen is simplified, and adjustment of the size of a large format and the size of a display format is easier to achieve; furthermore, from the aspects of a light-emitting mechanism and a display principle, the spectral intensity distribution of the projection excitation source focuses on an invisible light area, so that the contradiction between transparency and imaging brightness in traditional display equipment is overcome.

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned OLED display and LCD with LCD backlight are all screens with grids, in which the grid gaps and wire electrodes are opaque, and the light transmittance of this grid screen is limited

The holographic screen and diffusion film are screens with microstructures, which use the principle of diffuse reflection and scattering of projected light on the screen for imaging display. The scattered projected light becomes less, and the brightness of the display becomes lower
