Embodiment 1

[0030] figure 2A schematic cross-sectional structure diagram of the touch-sensitive liquid crystal display panel in the first embodiment of the present invention is shown. Please refer to figure 2 , figure 2 The shown touch liquid crystal display panel includes: an array substrate 12, a color filter substrate 14, a lower polarizer 15 arranged below the array substrate 12, an upper polarizer 16 arranged above the color filter substrate 14, a set The cover plate 18 above the upper polarizer 16 and the liquid crystal layer 13 between the array substrate 12 and the color filter substrate 14 . The touch-sensitive liquid crystal display panel further includes a touch-control layer 101 , wherein, in this embodiment, the touch-control layer 101 is disposed on the color filter substrate 14 and faces one side of the upper polarizer 16 .

[0031] For the specific structure of the touch layer 101, please refer to image 3 , image 3 It is a schematic structural diagram of the touc...

Embodiment 2

[0049] Please refer to Figure 7 , Figure 7 A schematic cross-sectional structure diagram of the touch-sensitive liquid crystal display panel in the second embodiment of the present invention is shown. Figure 7 The structure shown is the same as figure 2 The touch-sensitive liquid crystal display panel shown is similar, and the difference is that a shielding layer 122 is arranged between the touch-control layer 101 and the upper polarizer 16, and the shielding layer 122 is made of opaque inorganic or organic materials, for example, The light reflected by the metal surface of the touch layer 101 is blocked to prevent light reflection on the touch layer 101 . Wherein, in the embodiment of the present invention, the wiring lines of the shielding layer 122 can be connected with Figure 4 The wiring lines of the sensing electrodes 201 and the driving electrodes 203 are exactly the same, and the width of the wiring lines of the shielding layer 122 is larger than the width of t...

Abstract

The invention provides a touch type liquid crystal display panel and a touch type liquid crystal display device. The touch type liquid crystal display panel comprises a color filter substrate, an array substrate, a plurality of gate lines, a plurality of data lines, a touch layer and a conductive layer. The data lines and the gate lines intersect mutually and are distributed by insulating mutually, and an area formed by enclosing of each two adjacent data lines and each two adjacent gate lines intersecting with the two adjacent data lines forms a pixel unit. The touch layer made of metal materials is positioned on the color filter substrate, and the conductive layer made of transparent conductive materials is positioned on the touch layer and contacts with the touch layer electrically. Inductive electrodes and drive electrodes are arranged on the touch layer, each of the inductive electrodes and the drive electrodes comprises a vertically-arranged wire and a horizontally-arranged wire, a perpendicular space is kept between each vertically-arranged wire and the corresponding data line, each vertically-arranged wire and the corresponding data line are in superposed arrangement in the perpendicular direction, a perpendicular space is kept between each horizontally-arranged wire and the corresponding gate line, each horizontally-arranged wire and the corresponding gate line are in superposed arrangement in the perpendicular direction, and one end of each horizontally-arranged wire is electrically connected with the corresponding vertically-arranged wire. Touch precision of the touch type liquid crystal display panel can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a touch-sensitive liquid crystal display panel and a device. 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. On the other hand, with the rapid development and application of information technology, wireless mobile communication and information home appliances, in order to achieve more convenient, lighter and more humanized purposes, many information products have been input from traditional keyboards or mice and other devices. In order to use a touch panel (Touch Panel) as an ...
