Embodiment Construction

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] figure 2 It is a schematic cross-sectional structure diagram of the touch display panel according to the first embodiment of the present invention. like figure 2 As shown, the touch display panel includes a display substrate 30 , a touch sensing layer 20 and an upper polarizer 10 .

[0031] The display substrate 30 includes a color filter (color filter, CF) substrate 301 , a thin film transistor (Thin Film Transistor, TFT) 302 substrate, and a liquid crystal molecule layer 303 located between the CF substrate 301 and the TFT substrate 302 . Wherein, a black matrix (not shown in the figure) is disposed on the CF substrate 301 .

[0032] The touch sensing layer 20 is located above the display substrate 30 , and the touch sens...

Abstract

The invention provides a touch control display panel. The touch control display panel comprises a display substrate, a touch control sensing layer and an upper polarizer. The touch control sensing layer is located at the upper part of the display substrate, and the touch control sensing layer is used for sensing the touch control position. The upper polarizer is located at the surface of a back display substrate of the touch sensing level, and comprises a haze pressure-sensitive adhesive layer. The invention further provides a touch control display device using the touch control display panel. The touch control display panel and the upper polarizer of the touch control display device comprise the haze pressure sensitive adhesive layer, so that the interference stripe between the touch control sensing layer and the display substrate is reduced, the display quality is improved; moreover, it is beneficial for light and thin design of a product.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device using the same. Background technique [0002] With the increasing development of science and technology, digital tools such as mobile phones, personal digital assistants, and notebook computers are developing in the direction of convenience, multi-function and beauty. Among them, the display screen is an indispensable human-machine communication interface in these devices. At present, Most mainstream display screens use liquid crystal display technology. At the same time, with the rapid development and application of information technology, wireless mobile communications and information home appliances, in order to achieve more convenient, lighter and more humanized purposes, many information products have been converted from traditional keyboard or mouse input to use Touch panels (Touch Panel) are used as input devi...
