Embodiment 1

[0037] The grating structure is a parallax barrier grating structure to realize a 3D display with a touch function.

[0038] see Figure 5 The 3D touch display provided by the embodiment of the present invention includes: a display device 1, a grating structure 2 on the display device 1, a touch sensing circuit 3 on the body of the grating structure 2, and a protective layer 7 on the touch sensing circuit 3 . The touch sensing circuit 3 is located on a side of the grating structure 2 that is not in contact with the display device 1 .

[0039] The display device 1 may be a liquid crystal display device or other 2D display devices; Figure 5 The display device 1 shown in is a liquid crystal display device, including an array substrate 11, a color filter substrate 12, and a liquid crystal between the array substrate 11 and the color filter substrate 12 ( Figure 5 not shown in ). Since liquid crystal molecules have light selectivity, polarizers 5 are provided on the outer sid...

Embodiment 2

[0051] The grating structure provided by the embodiment of the present invention is a liquid crystal grating structure, and a 3D display with a touch function is realized through the liquid crystal grating structure.

[0052] The liquid crystal grating structure may be a light-transmitting and light-impermeable grating structure realized by TN liquid crystals.

[0053] see Image 6 , the 3D display with touch function includes: a display device 1, a liquid crystal grating structure 2 located on the display device 1, and a touch sensing circuit 3 formed on the liquid crystal grating structure 2; specifically, the touch sensing circuit 3 is formed on the liquid crystal grating structure 2 on the side of the upper substrate that is not in contact with the liquid crystal or the side that is in contact with the liquid crystal ( Image 6 The shown touch sensing circuit 3 is formed on the side of the liquid crystal grating structure 2 not in contact with the liquid crystal).

Abstract

The invention discloses a three-dimensional display and particularly relates to the three-dimensional touch display with a simple and compact structure. The three-dimensional touch display comprises a display device, a grating structure positioned above the display and a touch sensing circuit, wherein the touch sensing circuit is formed on a grating structure body.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a three-dimensional (3D) touch display. Background technique [0002] 3D stereoscopic display technology has become an important cutting-edge technology field in the display field. 3D stereoscopic display technology includes vision-aided 3D display and naked-eye 3D display. Among them, the naked-eye 3D display is a display that does not require any visual aid device to view the 3D effect. In the naked-eye 3D display technology, the 3D display based on the grating structure has attracted much attention due to its simple structure and good performance. Grating structure. [0003] With the development of 3D stereoscopic display technology and the increase of people's demand for products, there are still few 3D displays with touch function. Generally speaking, the method for realizing touch of 3D touch display is: directly set the touch screen above the 3D display, ...
