Problems solved by technology

Since the touch module and the 3D grating box are completely independent, in the production process of the display device, the touch module and the 3D grating box need to be combined to realize the 3D display and touch functions at the same time. Additional pasting process, high cost and long production time

Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 creative efforts fall within the protection scope of the present invention.

[0055] Such asfigure 1 As shown, the embodiment of the present invention provides a 3D grating box for a display device, comprising: a first substrate 1 and a second substrate 2, a first polarizer 11 is attached above the first substrate 1, and the second substrate 2 A second polarizer 21 is attached below. It should be noted that when the display panel in the display device is a liquid crystal panel, since the liquid crystal panel itself has a polariz...

Abstract

The invention discloses a 3D (three dimensional) raster box, a display device and a touch positioning method of the 3D raster box, and relates to the technical filed of touch. The touch function is added in the 3D raster box, and thereby the cost and the manufacturing time of the display device are reduced. The 3D raster box is characterized in that a plurality of strip-shaped electrodes are arranged in a first electrode layer, and a drive unit is connected with each strip-shaped electrode and is used for periodically inserting positioning signals which have opposite potential with drive signals into the drive signals of each strip-shaped electrode; a data acquisition layer and the first electrode layer are arranged at an interval, and the data acquisition layer comprises a plurality of parallel data acquisition lines; when a touch pressure is borne, the data acquisition lines at which the touch pressure is positioned are communicated with the strip-shaped electrodes at the intersection and acquire the positioning signals; and a positioning unit is used for determining the position at which the touch pressure is positioned at an inserting position in the same period according to the positioning signals acquired by the data acquisition lines.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a 3D grating box, a display device and a touch positioning method for the 3D grating box. Background technique [0002] With the development of mobile display devices such as mobile phones and MP4s, 3D display and touch functions have gradually become necessary functional modules of the display devices. In the existing display device, the touch function is realized by adding a touch module on the display screen, while for 3D display, a 3D grating box is installed in front of the display screen. Due to the shading of the light-shielding part in the 3D grating box, the user's left eye and active The eyes can see the picture with parallax respectively, so as to realize 3D display. Since the touch module and the 3D grating box are completely independent, in the production process of the display device, the touch module and the 3D grating box need to be combined to realize the 3D disp...
