Liquid crystal box, 3D touch control display device and control method thereof

Abstract

The invention discloses a liquid crystal box, a 3D touch control display device and a control method thereof. The liquid crystal box comprises a first baseplate, a second baseplate, a liquid crystal layer positioned between the first baseplate and the second baseplate, grating layers positioned on the first baseplate, a touch control electrode layer positioned on the second baseplate, as well as a second polarizer and a third polarizer positioned on one sides, opposite to the liquid crystal layer, of the first baseplate and the second baseplate respectively. Based on the structure, in a time-sharing period of a 3D display mode, driving voltage is applied to the touch control electrode layer and the grating layers in sequence, and touch driving and grating driving are performed in sequence; in the grating driving process, the touch control electrode layer performs ground connection by serving as the common electrode layer of the grating layers; in the process of touch driving, the grating performs ground connection, various electrodes of the touch control electrode layer serve as the touch control electrodes of the touch control module; one-step detection is performed to the touch control signal, the time of the process of touch driving is less than the retention time of liquid crystal molecules; when the 3D display is performed, the light splitting function and the touch control function of the grating are realized at the same time; and two layers of glass baseplates are saved.

Description

technical field [0001] The invention belongs to the field of 3D liquid crystal display, and in particular relates to a liquid crystal box, a 3D touch display device and a control method thereof. 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 three-dimensional (Three Dimension, 3D) stereoscopic display devices 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] The 3D display is mainly based on the principle of human vision to obtain two images of t...

Problems solved by technology

[0006] The structure of the existing 3D liquid crystal display device with integrated touch function includes: a liquid crystal display panel, a liquid crystal box positioned above the color filter substrate of the liquid crystal display panel, and a touch screen positioned above the liquid crystal box, wherein the liquid crystal display panel, the liquid crystal box and the touch screen each Including two layers of substrates, the substrates are generally glass substrates, that is to say, the existing 3D liquid crystal display device with touch function needs at least six layers of glass substrates to be bonded together. In modern society, thinner and more convenient display Under the demand conditions of the device, the above-mentioned 3D liquid crystal display device with touch function has a complicated structure, a large thickness, and high manufacturing cost, which cannot meet the needs of the modern society for a thinner and more convenient display device.
