Problems solved by technology

However, this type of touch device is often easily broken when dropped due to insufficient strength, especially because the optical glue does not completely cover the edge of the touch panel, making the edge of the touch panel that is not glued by the optical glue more fragile. When falling, it is easy to cause glass to splash and cause harm to the human body
[0003] The aforementioned phenomenon of cracking of the touch device and splashing of glass due to insufficient strength also occurs in the structure of the touch panel and the display device

Embodiment 1

[0052] In the following, the touch display device of the present invention is compared with the drop test of the traditional touch display device. In order to ensure the reliability of the test results, the traditional touch display device uses ordinary optical glue, while the touch display device of the present invention uses this The optical glue of the invention has the same structure as other components. Among them, sample 1 and sample 2 are touch display devices of the present invention, and sample 3 and sample 4 are traditional touch display devices.

Embodiment 2

[0057] A comparison of the drop test of the traditional touch display device and the touch display device of the present invention, wherein the structure of the traditional touch display device is: a single-chip touch panel, a hard coating film, a traditional optical glue, and a liquid crystal display module stacked in sequence Plus, the touch display device of the present invention uses figure 2 The touch display device 100 corresponding to the embodiment is a test sample, wherein the touch panel is image 3 The single-chip touch panel 140 of the embodiment is taken as an example. The traditional touch display device (sample 4, sample 5) and the touch display device of the present invention (sample 1, sample 2, sample 3) were dropped and dropped with different steel ball weights (100g, 130g, 150g) respectively (ball height :100cm). The test results are shown in Table 3 below.

Abstract

The present invention provides a touch panel. The touch panel comprises: a substrate; a cover plate provided on the substrate; an optical glue disposed between the substrate and the cover plate, wherein an elastic modulus of the optical glue is between 1x10<7> Pa and 1x10<10> Pa; and a touch sensing layer disposed an upper surface or a low surface of the substrate or the upper surface and the low surface of the substrate. The present invention further provides a touch display device and a display device. The present invention further provides a touch display device and a display device, which both comprise an optical glue with a relatively great elastic modulus. Therefore, anti-drop strength of products can be effectively improved, the rupture of the edge of the cover plate or the touch panel is reduced so that the splinters are not easy to spread, and damage to the human body is reduced.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch panel with high strength and good explosion-proof performance, a touch display device and a display device. Background technique [0002] For the current touch device, in order to facilitate subsequent assembly, the size of the touch panel (TP for short) is generally slightly larger than that of the liquid crystal display module (LCM for short). The two are usually bonded with optical clear adhesive (OCA for short). However, this type of touch device is often easily broken when dropped due to insufficient strength, especially because the optical glue does not completely cover the edge of the touch panel, making the edge of the touch panel that is not glued by the optical glue more fragile. When falling, it is easy to cause glass to splash and cause harm to the human body. [0003] The aforementioned phenomenon of cracking of the touch device and splashing of glass...
