Problems solved by technology

[0004] However, in the prior art, the touch electrodes and the controller are generally connected together through a single wire, such as figure 1 As shown, the touch electrodes 101 and the controller 102 are connected together through a wire 103. However, during the manufacturing process of the touch screen, it generally needs to go through an exposure process, and in the exposure process, dust and foreign matter will be generated. Such as tiny particles or a large amount of static electricity will cause the wire to be disconnected, causing the touch electrode to fail due to the disconnection of the signal wire
And there is no effective method for checking the failure of touch electrodes, which undoubtedly brings hidden dangers to users

Embodiment Construction

[0023] see figure 2 , figure 2 It is a schematic structural diagram of an embodiment of the touch panel of the present invention. The touch panel of this embodiment is an in-cell self-capacitive touch panel. The touch panel in this embodiment includes a plurality of touch electrodes 201 and a controller 202 arranged in a matrix. In this embodiment, the touch electrodes 201 are nano-indium tin metal oxide ITO electrodes.

[0024] Wherein, each touch electrode 201 and the controller 202 are connected by at least two wires. like figure 2 As shown, in this embodiment, each touch electrode 201 and the controller 202 are connected through two wires 203 and 204 .

[0025] In order to make the entire touch panel more concise and the circuit clearer, in a preferred embodiment, the wires 203 and the wires 204 are respectively on different layers of the circuit board where the touch electrodes 201 are located, as shown in the touch electrodes 201 . The circuit board here is a 4-...

Abstract

The invention discloses a touch panel and a touch type display device. The touch panel comprises a controller and a plurality of arrayed touch electrodes, and each touch electrode is electrically connected with the same pin of the controller through at least two leads. By the mode, the problem of disconnection of the leads among the touch electrodes and the controller can be effectively improved, defective rate is decreased, and the service life of the touch panel is prolonged.

Description

technical field [0001] The present invention relates to the field of touch control, and in particular, to a touch panel and a touch display device. Background technique [0002] The touch screen, also known as the touch panel, is an inductive liquid crystal display device that can receive input signals such as finger touches. , determine the position of the touch action, further determine the button of the clicked graphic, and determine the instruction type. Compared with the mechanical button panel in the prior art, the touch screen is more convenient, so it has been widely used. [0003] There are many commonly used touch screens, such as vector pressure sensing technology touch screens, infrared technology touch screens, surface acoustic wave technology touch screens, resistive technology touch screens, etc., but capacitive technology touch screens are more commonly used in the prior art. Capacitive touch technology is a touch technology that utilizes changes in capacit...
