Embodiment 1

[0032] Such as figure 1 As shown, this embodiment provides an infrared touch display device 100 , which includes a display panel 1 , an optical adhesive layer 2 , a cover plate 3 , an infrared touch panel 4 and a microstructure layer 5 stacked from bottom to top.

[0033] The display panel 1 is a liquid crystal display panel, an organic light-emitting diode display panel, an active matrix organic light-emitting diode display panel, or a polymer light-emitting diode display panel.

[0034] The optical adhesive layer 2 is annularly arranged on the periphery of the upper surface of the display panel 1; the optical adhesive layer 2 surrounds to form a vacuum chamber 21; specifically, the optical adhesive layer 2 is annularly arranged on the The periphery of the upper surface of the display panel 1 ; the area surrounded by the optical adhesive layer 2 forms a vacuum chamber 21 ; in this embodiment, the optical adhesive layer 2 is preferably a rectangular ring, and the center of the...

Embodiment 2

[0046] Such as Figure 5 As shown, the second embodiment includes all the technical features of the first embodiment, the difference is that the microstructure layer 5 in the second embodiment is arranged on the display panel 1 facing the optical adhesive layer 2 The surface on one side, instead of the microstructure layer 5 in the first embodiment, is disposed on the surface of the cover plate 3 facing the optical adhesive layer 2 .

[0047] In this embodiment, the anti-glare film 51 is formed by atomizing the surface of the display panel 1 facing the optical adhesive layer 2 . The atomization treatment includes forming the anti-glare film 51 by corroding the surface of the film layer, and the microstructure layer 5 can effectively improve reflection and visual interference.

[0048] Such as Figure 4 , Figure 5 As shown, the microstructure layer 5 includes the antiglare film 51 and the base layer 52 ; the antiglare film 51 is disposed on the base layer 52 . The existenc...

Embodiment 3

[0050] Such as Figure 6a , Figure 6b As shown, in order to further enhance the display effect, the third embodiment includes all the technical features of the first embodiment and the second embodiment, the difference is that the third embodiment is further provided with a second microstructure layer 5, which is arranged between the cover plate 3 and the infrared touch panel 4.

[0051] Such as Figure 6a , Figure 6b Shown are two structural schematic diagrams in the third embodiment, Figure 6a and figure 1 The difference is that in figure 1 A second layer of microstructure layer 5 is added to the surface of the cover plate 3 facing the side of the optical adhesive layer 2; Figure 6b and Figure 5 The difference is that in Figure 5 A second layer of microstructure layer 5 is added on the surface of the display panel 1 facing the side of the optical adhesive layer 2 on the basis of . By disposing the second microstructure layer 5 above the cover 3 and disposing t...

Abstract

The invention provides an infrared touch display device. The infrared touch display device comprises a display panel, an optical adhesive layer, a cover plate, an infrared touch panel and a microstructure layer which are stacked from bottom to top. The optical adhesive layer is annularly arranged on the periphery of the upper surface of the display panel; a vacuum cavity is formed in an area defined by the optical adhesive layer; the cover plate is arranged on the optical adhesive layer; the infrared touch panel is arranged on the cover plate; and the microstructure layer is arranged on one side surface of the cover plate and plays an anti-dazzle role. According to the infrared touch display device, the microstructure layer is arranged between the cover plate and the infrared touch panel,and the microstructure layer is provided with the concave-convex diffuse reflection surface, so that the anti-dazzle effect can be achieved, the rainbow pattern phenomenon is improved, and the visualeffect of the infrared touch display device is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to an infrared touch display device. Background technique [0002] In the field of display, infrared touch is currently occupying a large part of the market in the field of touch by virtue of mature technology, accurate touch precision, and relatively cost advantages. The principle of infrared touch is to analyze the touch position by blocking the infrared rays emitted by the infrared frame for positioning. [0003] In recent years, in the field of display, infrared touch display devices are used as educational whiteboards and high-end conference machines. In order to facilitate operation and demonstration, large-size touch technology is required. The current mainstream touch technology is infrared technology. However, since the structure of the infrared touch display device includes a stacked display panel, an infrared touch panel, and a cover plate, there is a vacuum cavity between th...
