Technology realization scheme of naked eye 2D and 3D display screen

Abstract

The invention provides a technology realization scheme of a naked eye 2D and 3D display screen. The scheme is characterized in that a lenticular grating of a 3D naked eye display screen is arranged between a liquid crystal panel and a liquid crystal back plate; then, an electronic light scattering plate is added between the lenticular grating and the liquid crystal panel; the work state of the electronic light scattering plate is controlled through a driving circuit in a machine and application software, so that the switching between 2D images and 3D images can be realized. The existing lenticular grating is combined for naked eye 3D display; through relevant technology and equipment, the 3D video playing can be realized; the 2D video playing can also be realized; the light transmission quantity of the display screen can be increased; the brightness of the 3D images can be effectively improved; the 3D image effect is improved; the 2D image display effect is not influenced. On the basis, the technology realization scheme has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of 3D display, in particular to a technical implementation scheme of naked-eye 2D and 3D display screens. Background technique [0002] The 3D naked-eye display screen can bring users an immersive video viewing effect during video playback, and is a technology with great development prospects. The existing 3D naked-eye display mainly adopts the technical method of using cylindrical lens grating or slit grating for naked-eye 3D display; due to the current technical constraints, although the use of cylindrical lens grating has high light transmittance and close to 0 light loss, the 3D picture The brightness is high, but the disadvantage is that 3D and 2D cannot be switched. After naked-eye 3D display, the display screen can only display 3D images, and can no longer display 2D images. The function is single; although the slit grating can switch between 2D and 3D , but in actual work, the light transmittance wi...

The existing 3D naked-eye display mainly adopts the technical method of using cylindrical lens grating or slit grating for naked-eye 3D display; due to the current technical constraints, although the use of cylindrical lens grating has high light transmittance and close to 0 light loss, the 3D picture The brightness is high, but the disadvantage is that 3D and 2D cannot be switched. After naked-eye 3D display, the display screen can only display 3D images, and can no longer display 2D images. The function is single; although the slit grating can switch between 2D and 3D , but in actual work, the light transmittance will be affected, making the 3D picture darker; in fact, due to the constraints of the existing 3D technology, some video pictures can not be played by 3D display to achieve the effect of 2D display. It cannot be selected according to needs, so users cannot get the best experience every time they watch a video, which restricts the promotion of 3D naked-eye display
