Embodiment 1

[0029] like figure 1 As shown, this embodiment provides a touch display device 100 , including a display panel 1 , a touch panel 2 , a first adhesive layer 3 , a cover plate 4 and a microstructure layer 5 .

[0030] 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.

[0031] The touch panel 2 is arranged on the upper surface of the display panel 1; the shape and size of the touch panel 2 are the same as those of the display panel 1, thereby effectively ensuring that the touch panel 2 The operable area of ​​is consistent with the operable area of ​​the display panel 1 .

[0032] The first adhesive layer 3 is ring-shaped and arranged at the edge of the upper surface of the touch panel 2; the middle part of the first adhesive layer 3 is surrounded to form a vacuum chamber 31; specifically, the first adhesive layer 3 Set...

Embodiment 2

[0043] like image 3 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 touch panel 2 facing the cover plate 4 One side surface, instead of the microstructure layer 5 in the first embodiment, is disposed on the surface of the cover plate 4 facing the touch panel 2 . The microstructure layer 5 can effectively improve reflection visual interference.

[0044] like figure 2 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 presence of the base layer 52 enables the microstructure layer 5 to be attached to the touch panel 2 through the base layer 52 instead of just being formed on the touch panel 2 through atomization. The microstructure layer 5 . This is convenient and saves process time.

Embodiment 3

[0046] like Figure 4a , Figure 4b As shown, in order to further enhance the display effect, all the technical features in the first embodiment and the second embodiment are included in the third embodiment, the difference is that the third embodiment can also be separated from the cover plate 4 A layer of the microstructure layer 5 is provided on the surface of one side of the touch panel 2 .

[0047] like Figure 4a , Figure 4b Shown are two structural schematic diagrams in the third embodiment, and the difference is that Figure 4a The microstructure layer 5 is provided on the surface of the cover plate 4 facing the touch panel 2; Figure 4b The microstructure layer 5 is disposed on the surface of the touch panel 2 facing the cover plate 4 .

[0048] It is worth noting that, if Figure 4a , Figure 4b As shown, the microstructure layer 5 can be above and below the cover plate 4 at the same time. By setting two microstructure layers 5 above and below the cover plate...

Abstract

The invention provides a touch display device. The touch display device comprises a display panel, a touch panel, a first adhesive layer, a cover plate and a microstructure layer, wherein the touch panel is arranged on the display panel; wherein the first adhesive layer is annularly arranged at the edge of the touch panel; a vacuum cavity is formed in the middle of the first adhesive layer in a surrounding manner; the cover plate is arranged on the first adhesive layer; and the microstructure layer is arranged on one side surface of the cover plate, and the microstructure layer can play an anti-dazzle role. According to the touch display device, the microstructure layer is arranged between the cover plate and the touch panel, and the microstructure layer is provided with the concave-convexdiffuse reflection surface, so that the anti-dazzle effect can be achieved, the rainbow pattern phenomenon is improved, and the visual effect of the touch display device is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a touch display device. Background technique [0002] In recent years, in the field of display, the development of touch display devices has continued to grow. However, since the structure of touch display devices includes a display panel, a touch panel, and a cover plate that are stacked, after vacuum bonding, the cover plate and touch panel There is a vacuum chamber between them. Due to the negative pressure of the vacuum chamber, the cover plate is bent towards the side of the vacuum chamber, and the cover plate is stretched, resulting in uneven thickness of the cover plate. The position of the cover plate with different thickness forms a large difference in the light path. Or other factors cause the user to observe the rainbow pattern (rainbow mura) and affect the visual effect. [0003] Therefore, it is indeed necessary to develop a novel touch display device in order to overcom...
