Touch display module and display device

Abstract

The invention discloses a touch display module and a display device. The display module comprises an upper substrate, a lower substrate arranged opposite to the upper substrate, a liquid crystal layer arranged between the upper substrate and the lower substrate, and a control chip, wherein one side, which faces the lower substrate, of the upper substrate is provided with a first strip-shaped electrode; one side, which faces the upper substrate, of the lower substrate is provided with a second strip-shaped electrode; the extension directions of the first strip-shaped electrode and the second strip-shaped electrode intersect with each other; the control chip is connected with the first strip-shaped electrode and the second strip-shaped electrode; during 3D (three-dimensional) display, the control chip is used for driving the first strip-shaped electrode and the second strip-shaped electrode in order to realize the function of a liquid crystal lens or a liquid crystal grating; during 2D (two-dimensional) display, the control chip is used for driving the first strip-shaped electrode and the second strip-shaped electrode in order to realize the function of positioning touch operation. By adopting the display module, 3D display can be performed. During 2D display, a touch positioning function can be realized without adding any touch layer, so that the transmittance and light and thin design of the display module are facilitated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch display module and a display device. Background technique [0002] At present, 3D display technology has attracted much attention. The basic principle of 3D display is to use the left and right eyes to receive different images, and then process the image information by the brain to form a three-dimensional effect. In order to realize 3D display, a layer of naked-eye 3D grating is added on the display screen in the prior art. There are two types of naked-eye 3D grating: slit grating and cylindrical lens grating. The process of grating realizing 3D is to add A liquid crystal box, the liquid crystal box includes a first substrate and a second substrate, and a liquid crystal layer filled in the middle of the two substrates, by adjusting the electric field formed by the first substrate and the second substrate, the liquid crystal is poured in a certain direction, forming a si...
