Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] see figure 1 , which provides a touch display panel 90 , the touch display panel 90 includes a cover plate 901 , a touch sensing layer 902 and a display module 120 sequentially arranged from top to bottom. Wherein, the touch sensing layer 902 is used to detect the touch position, and the touch sensing layer 902 can be bonded to the cover plate 901 through an optical glue (not shown), or can directly use photolithography The process is used to form the surface of the cover plate 901, which is not limited by this embodiment. Afterwards, the cover plate 901 integrated with th...

Abstract

The invention provides a touch display system with a pressure sensing function. The touch display system comprises a touch sensing layer and a display module, wherein the display module further comprises a conductive shielding layer; the touch sensing layer is arranged on the display module and insulated from the conductive shielding layer; and the conductive shielding layer is used for providing the pressure sensing function at a first time sequence and is used for providing a ground connection for the display module at a second time sequence. By adopting the touch display system with the pressure sensing function, provided by the invention, the pressure sensing function can be realized in the touch display system without arranging a pressure sensing layer, so that the pressure sensing structure can be simplified and the cost can be reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of touch display, in particular to a touch display system with pressure sensing. [0003] 【Background technique】 [0004] Touch display panels are widely used in various consumer electronic devices, such as portable electronic products such as smart phones, tablet computers, cameras, e-books, and MP3 players, or display screens for operating control devices. In recent years, a touch display panel capable of sensing pressing force (also known as three-dimensional touch sensing) has attracted extensive attention. [0005] In order to realize the pressure sensing method in the prior art, it is generally necessary to add an additional pressure sensor to the structure to achieve the pressure sensing function. However, the pressure sensor generally includes a carrier substrate and a pressure sensing electrode layer formed on the carrier substrate, and the pressure sensor is then bonded to the touch display panel by...
