2D/3D (Two-dimensional/three-dimensional) switchable auto-stereoscopic display device based on blue phase liquid crystal lens

Abstract

The invention discloses a 2D / 3D (Two-dimensional / three-dimensional) switchable auto-stereoscopic display device based on a blue phase liquid crystal lens. The device comprises a blue phase liquid crystal lens and a 2D display screen; and the blue phase liquid crystal lens is arranged right above the 2D display screen. The blue phase liquid crystal lens comprises an upper substrate glass layer, an upper substrate ITO (Indium Tin Oxide) transparent arc-shaped electrode, an upper substrate polymer layer, a blue phase liquid crystal layer, a lower substrate ITO transparent planar electrode and a lower substrate glass layer. The 2D / 3D switchable auto-stereoscopic display device based on the blue phase liquid crystal lens provided by the invention realizes the switching of a 2D mode and a 3D mode in the auto-stereoscopic display through the control of voltage; when the voltage does not exist between the upper substrate ITO transparent arc-shaped electrode and the lower substrate ITO transparent planar electrode, a 2D display screen displays 2D images without parallax errors, and at the moment, the device works in the 2D mode; and when the voltage is applied between the upper substrate ITO transparent arc-shaped electrode and the lower substrate ITO transparent planar electrode, the 2D display screen displays the 2D images with left and right parallax errors, and at the moment, the device works in the 3D mode.

Description

technical field [0001] The present invention relates to the field of display, and more particularly, to the field of autostereoscopic display, in particular to a 2D / 3D (two-dimensional / three-dimensional) switchable autostereoscopic display device based on a blue phase liquid crystal lens. Background technique [0002] Autostereoscopic display technology is a naked-view 3D display technology. Based on the principle of binocular parallax, it sends the left and right parallax images displayed on the 2D display screen to the left and right eyes of the viewer respectively through the slit grating or cylindrical lens grating installed in front of the 2D display screen. Stereoscopic perception is obtained after brain fusion. The slit grating is composed of a certain size of light-transmitting strips and light-blocking strips arranged alternately, and the separation of the parallax image is obtained through its light transmission and blocking effect; the cylindrical lens grating is...

Problems solved by technology

The use of liquid crystal lenses will not significantly reduce the brightness of image display, but because the liquid crystal lens uses traditional liquid crystal materials, its response speed is slow, and it only works on incident light of a specific polarization state
