Mini-LED display submodule and large-size naked-eye 3D display device

By employing a double-layer grating structure on the Mini-LED display panel, and using the first lens to collimate the light and the second grating layer to directionally refract it, the problems of uneven light intensity and crosstalk in LED screens are solved, achieving high-quality naked-eye 3D display, which is suitable for large-size display devices.

AI Technical Summary

Technical Problem

Existing naked-eye 3D display technology for LED screens suffers from uneven light intensity and crosstalk issues, which lead to a decline in the quality of 3D image display. This is especially true when displaying on large screens, where the light intensity attenuation is significant, affecting the viewer's viewing experience.

Method used

It adopts a double-layer grating structure, including a Mini-LED display panel, a first grating layer and a second grating layer. The first lens converts the light into collimated light, and the second grating layer is used for directional refraction, so that the light is projected to different viewpoints in space, avoiding uneven light intensity and crosstalk.

Benefits of technology

It improves the display quality of 3D images, ensures uniform light intensity distribution, reduces crosstalk, provides a clearer and more comfortable naked-eye 3D viewing experience, and supports large-size displays.

Abstract

The invention relates to a Mini-LED display submodule and a large-size naked-eye 3D display device. The Mini-LED display submodule comprises a display panel, a first grating layer and a second grating layer which are arranged in sequence. The display panel comprises a plurality of pixel units, the first grating layer comprises a plurality of first lenses, and the first lenses are used for converting emergent light rays emitted by the corresponding pixel units into collimated light rays; the focal points of the multiple first lenses are arranged in a coplanar mode, light rays passing through the first lenses can be converted into collimated light rays with unified parameters, the multiple pixel units and the multiple first lenses are arranged in a one-to-one correspondence mode, independent regulation and control of single emergent light rays can be achieved, and the problem of cross crosstalk of different emergent light rays is greatly solved in combination with collimation processing of the first lenses; by arranging the second grating layer, directional refraction can be carried out on the collimated light rays output by different first grating layers, the collimated light rays after refraction are respectively projected to different viewpoint positions in the space, and naked eye 3D display can be realized.
