Problems solved by technology
Compared with the traditional 3D display device, the 3D touch display device with this structure has a larger overall thickness of the display device. Excessive box thickness not only affects the 3D display effect of the display device, but also makes the processing and manufacturing of the display device more complicated. , which increases the cost of production

Embodiment Construction
[0016] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] In order to further understand the present invention, the present invention will be described in detail below in conjunction with examples.
[0018] In the prior art, the touch electrodes in the 3D touch display device are usually double-layered, which will lead to the increase in thickness of the 3D touch display device and high manufacturing cost. In order to solve the problems in the prior art, the present invention proposes a 3D touch liquid crystal ...

The invention discloses a three-dimensional touch liquid crystal lens grating. The grating comprises a first substrate, a second substrate and a liquid crystal layer which is located between the firstsubstrate and the second substrate. The second substrate and the first substrate are oppositely arranged. The first substrate includes a first transparent substrate and at least one first strip electrode. The second substrate includes a second transparent substrate and at least one second strip electrode. The liquid crystal layer is located between the first strip electrodes and the second stripelectrodes. One or more adjacent touch electrodes are further arranged between the second transparent substrate and the second strip electrode. Transparent insulation cushion layers are arranged between the touch electrodes and the second strip electrodes. In the three-dimensional touch liquid crystal lens grating, the second strip electrodes and the first strip electrodes form the liquid crystallens grating, at the same time, the second strip electrodes driving liquid crystals to deflect to form the liquid crystal lens grating serve as drive electrodes of a touch screen meanwhile, thus, thethickness of a three-dimensional touch display device is reduced, the manufacturing procedure is simplified, and the production cost is reduced.
Description
technical field [0001] The invention relates to the field of display technology, and more specifically, to a 3D touch liquid crystal lens grating. Background technique [0002] With the development of display technology, 3D (Three Dimensions, three-dimensional graphics) display devices with stereoscopic display effects and touch screens supporting touch control are increasingly sought after by consumers. Integrated products with both 3D display and touch screen touch functions are attracting more and more people's attention. [0003] At present, display devices with both 3D display and touch screen support functions are usually obtained by superposition, that is, the double-layer electrodes for touch control are additionally processed on the 3D display device that has been formed into a box. Compared with the traditional 3D display device, the 3D touch display device with this structure has a larger overall thickness of the display device. Excessive box thickness not only a...
