A multi-view glasses-free 3D display area compensation method based on lenticular grating

Abstract

The invention relates to the field of naked eye 3D display, especially to a region compensation method of multi-view naked eye 3D display based on the cylindrical mirror grating. The region compensation method of the multi-view naked eye 3D display based on the cylindrical mirror grating comprises the following steps: dividing the screen into a plurality of regions according to the design parameter features of the naked eye 3D display device; and debugging each area as an independent sub-screen. The region compensation method of the multi-view naked eye 3D display based on the cylindrical mirror grating provided by the invention can reduce the deformation of the liquid crystal screen and the deformation of the grating, and can reduce the affect of the 3D effect caused by the unevenness generated by the lamination of the liquid crystal screen and the grating, therefore, the display effect of the naked eye 3D is improved.

Description

technical field [0001] The invention relates to the field of naked-eye 3D display, in particular to a method for area compensation of a multi-viewpoint naked-eye 3D display based on a lenticular grating. Background technique [0002] At present, the naked-eye 3D display device based on lenticular lens grating technology, its naked-eye 3D display screen is composed of a liquid crystal screen and a grating. Frame-mounted technology (the LCD screen and the grating are fixed together by mechanical components, and there is a gap of a certain width between the LCD screen and the grating), both the LCD screen and the grating will be deformed, resulting in relatively unevenness between the LCD screen and the grating, and light When the separation is not uniform after grating refraction, when the final debugging effect is achieved, the 3D effect will be obvious in some places on the display screen, and ghosting and blurring will appear in some places, which will affect the experience...

[0002] At present, the naked-eye 3D display device based on lenticular lens grating technology, its naked-eye 3D display screen is composed of a liquid crystal screen and a grating. Frame-mounted technology (the LCD screen and the grating are fixed together by mechanical components, and there is a gap of a certain width between the LCD screen and the grating), both the LCD screen and the grating will be deformed, resulting in relative unevenness between the LCD screen and the grating, and light The uneven separation after grating refraction leads to obvious 3D effect in some places on the display screen when the final debugging effect is achieved, and ghosting and blurring in some places, which affects the experience of 3D effect

[0003] However, it is extremely difficult to reduce the deformation of the LCD screen and the grating, as well as the unevenness of the bonding of the LCD screen and the grating, by improving the process, and it will also bring high costs to production.
