2D/3D switching integrated imaging stereoscopic display device

Abstract

The invention discloses a 2D / 3D switching integrated imaging stereoscopic display device, and the device comprises a backlight unit which is used for generating backlight supporting 2D display; a side-light type guide plate which is used for generating a spot light source array supporting 3D display; a switching control unit which is used for switching and controlling the on / off states of the backlight unit and the side-light type guide plate, and enables only one of the backlight unit and the side-light type guide plate to be switched on at each time; and a transmission-type display panel which is used for displaying a corresponding 2D / 3D image according to the switching and controlling results of the switching control unit. The device is simple in structure, is low in cost, is high in utilization rate of optical energy, can be used for watching for a plurality of persons, and does not cause vision fatigue.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a 2D / 3D switchable integrated imaging stereoscopic display device. Background technique [0002] With the development of display technology, 3D display is developing towards popularization. Compared with ordinary 2D display, 3D display can provide depth information of objects, making viewing more realistic. [0003] The existing common 3D display technologies are as follows: (1) wearing polarized glasses, the left and right lenses of the glasses are a pair of orthogonal polarizers, and the parallax images of the left and right eyes are respectively displayed with orthogonal polarized light, so the left and right eyes are respectively obtained Corresponding to the parallax image, the brain fusion produces a three-dimensional effect. Due to the need to wear special glasses, the viewing comfort is greatly reduced. Due to the use of polarizers, the utilization of ligh...

AI Technical Summary

Problems solved by technology

This technology does not require special glasses, but the viewing position is fixed and it is difficult to meet the viewing needs of multiple people, so it is not very practical

Moreover, the above technologies will cause visual fatigue during viewing

[0004] The 2D / 3D switchable display has high practicability because it integrates 2D and 3D display functions at the same time; however, the current common 2D / 3D switchable display uses liquid crystal lens and liquid crystal grating technology, which are expensive and The viewing position is fixed and cannot be watched by multiple people at the same time
