Embodiment Construction

[0030] This embodiment proposes an anti-static touch display device, which includes a touch panel and a display device arranged in parallel. A transparent shielding layer is provided between the touch panel and the display device, and a low-impedance material connected to the common ground is provided on the periphery of the transparent shielding layer, so that the touch-sensitive display device not only has display and touch operation, but also improves noise suppression and Static protection effect.

[0031] Please refer to figure 1 , which is a schematic diagram of an anti-static touch display device according to a preferred embodiment of the present invention. Such as figure 1 As shown, the touch display device 1 includes a touch panel 10 , an active matrix substrate 12 , a transparent shielding layer 14 and a low impedance material layer 16 . The active array substrate 12 is disposed parallel to the touch panel 10 and is, for example, a thin film transistor array subst...

Abstract

The invention discloses a touch display device, which comprises a display device, a touch panel and a transparent shielding layer, wherein the touch panel is arranged on the display device and comprises a substrate and a touch element. The transparent shielding layer is arranged between the display device and the touch element and comprises a peripheral region and a central region, wherein the resistance of the peripheral region is smaller than or equal to the resistance of the central region.

Description

technical field [0001] The present invention relates to a display device, and in particular to an anti-static touch display device. Background technique [0002] Since the development of touch panel technology, touch panels have occupied a very high market share in consumer electronic products. At present, products such as communication mobile phones, notebook computers, PDAs, and digital cameras integrated with touch panels can be seen in the market. [0003] Since the touch panel is operated by a finger or a stylus, it is very prone to electrostatic interference or external noise, which directly or indirectly affects the electronic operation signals of other electronic components in the product. For example, a general touch panel can be applied to a liquid crystal display device. When electrostatic discharge occurs, static electricity may be introduced into the liquid crystal panel through the common electrode (Vcom) of the liquid crystal display device, or even damage th...
