Embodiment 1

[0055] refer to figure 1 , figure 1 It is a schematic structural diagram of the auxiliary display device provided in Embodiment 1 of the present invention, the auxiliary display device includes a three-dimensional stereoscopic display function module and a touch function module superimposed on it, and the three-dimensional stereoscopic display function module is a switchable grating The liquid crystal light valve, the switchable grating liquid crystal light valve includes: a first glass substrate 1 and a second glass substrate 2 oppositely arranged; A polarizer 3, a first electrode 4, a liquid crystal layer 6, and a second electrode 5; wherein, the first electrode 4 and the second electrode 5 are a plurality of strip electrodes distributed in a network, such as figure 2 As shown, and the liquid crystal layer 6 is sealed by the surrounding frame glue 7 .

[0056] The touch function module may be a resistive touch function module or a capacitive touch function module. figure...

Embodiment 2

[0061] refer to image 3 , image 3 It is a schematic structural diagram of the auxiliary display device provided in Embodiment 2 of the present invention, and the auxiliary display device includes a three-dimensional stereoscopic display function module and a touch function module superimposed thereon. The difference between this embodiment and the previous embodiment is that the three-dimensional stereoscopic display function module is an active polarized liquid crystal light valve, which needs to cooperate with polarized glasses to realize stereoscopic display. The active polarized liquid crystal light valve includes: a first glass substrate 1 and a second glass substrate 2 oppositely arranged; a fourth electrode 13, a liquid crystal layer 6 and the fifth electrode 14, wherein the fourth electrode 13 and the fifth electrode 14 are a plurality of strip electrodes distributed in a network, and the liquid crystal layer 6 is sealed by the surrounding frame glue 7.

Abstract

The invention discloses an auxiliary display device and a stereo display device. The auxiliary display device comprises a three-dimensional stereo display function module and a touch-control function module, wherein the three-dimensional stereo display function module is a liquid crystal light valve, and the liquid crystal light valve comprises multiple strip-shaped electrodes which are in net-shaped arrangement. The touch-control function module is overlaid above the three-dimensional stereo display function module, and the same glass substrate is shared at the connecting position of the touch-control function module and the three-dimensional stereo display function module. The stereo display device comprises a liquid crystal display and the auxiliary display device which is overlaid with the liquid crystal display. The stereo display device is capable of achieving a simultaneous display of three-dimensional frames and two-dimensional frames, thin in thickness and less in assembling process.

Description

technical field [0001] The present invention relates to the field of three-dimensional display and touch technology, in particular to an auxiliary display device and a three-dimensional display device. Background technique [0002] With the rapid development of display technology, people can no longer be satisfied with two-dimensional (Two Dimension, 2D) display images, but need a three-dimensional (Three Dimension, 3D) stereoscopic display device to provide a sense of depth and more comprehensive Information. After more than ten years of development, 3D display technology has achieved very fruitful results. There have been devices capable of 3D imaging such as handheld observers, 3D stereoscopic glasses, and helmet displays. Up to now, the latest ones that do not need glasses Glasses-free 3D display using technical solutions such as prisms, lenses, gratings, and electronic switches. [0003] However, in real life, we don’t need all the pictures to be three-dimensional. So...
