A 2D and glasses-free 3D split-screen playback display based on a special-shaped screen

Abstract

The invention discloses a naked-eye 2D and 3D split-screen display based on a special-shaped screen; the naked-eye 2D and 3D split-screen display comprises the special-shaped screen formed by cutting a standard liquid crystal screen in a partial clock signal removal manner as well as a corresponding backlight module; the special-shaped screen is provided with naked-eye 3D and 2D frequency-division display areas, wherein a bearing material is attached to the front part of the naked-eye 3D area and an optical grating is attached on the bearing material of the naked-eye 3D area; the optical grating attached at the joint of the naked-eye 3D area and the naked-eye 2D area is thicker and the bevel edge of this optical grating has an angle Alpha with the surface of the bearing material; the angle Alpha is taken as proper when the light from the surface of the special-shaped screen is parallel with the screen surface and then is refracted. With adoption of the above scheme, the naked-eye 2D and 3D multi-area display is realized on hardware and the original programs and software are simplified; because videos do not need to be subjected to compression and reduction of resolution ratios, the naked-eye 2D and 3D split-screen display is more reliable and pictures are better and more comfortable; with the processing of the critical edge (joint) of the 3D and 2D display, the display is uniform in the whole transition and stronger in zoning property.

Description

technical field [0001] The invention relates to the field of vehicle-mounted multimedia video playback systems, in particular to a 2D and naked-eye 3D split-screen playback display based on a special-shaped screen. Background technique [0002] The content played on the special-shaped screen is currently limited to 2D pictures, videos, and mixed video and pictures. No 3D and 2D video mixed playback or naked-eye 3D and 2D mixed playback modes have been found on the special-shaped screen. [0003] The main reasons for the above phenomena are: [0004] 1. The requirements for processing standard screens into special-shaped screens are very strict (not all standard screens are available), and the larger the size, the more difficult it is to cut; [0005] 2. The displayable size of the screen directly affects the effect of 3D video playback; [0006] The above two points are a contradictory relationship; [0007] 3. Glasses-free 3D and 2D videos are played in split screens on ...

AI Technical Summary

Problems solved by technology

[0007] 3. Glasses-free 3D and 2D videos are played in split screens on special-shaped screens. Compared with playing 2D content alone, the design of structure, heat dissipation, hardware, software and other aspects will be more complicated;

[0008] 4. Most of the scenes used for special-shaped screens are environments with limited space, vibration, and harsh convection conditions
