Problems solved by technology

[0005] Common problems on touch panels are circuit damage or signal anomalies caused by Electrostatic Discharge (ESD), especially the bridge components located at signal intersections between different sensing pads are more susceptible to damage. Effects of Electrostatic Discharge
[0006] When an abnormal discharge current occurs on the touch panel, it is easy to accumulate a potential difference near the bridge, and the bridge component is narrow and long and cannot withstand high voltage or high current. Therefore, it is easy to leak on the bridge or nearby areas Electrostatic damage is likely to occur, resulting in an open circuit or short circuit of the sensing serial signal in the X-axis or Y-axis direction, resulting in abnormal function of the touch module

Embodiment Construction

[0023] see figure 1 , which shows a schematic top view of a touch panel 100 according to an embodiment of the disclosure. Such as figure 1 As shown, the touch panel 100 includes a substrate 120 and a plurality of sensor pads 140 distributed on different positions on the substrate 120 . In practical applications, the sensing pads 140 can be rhombus-shaped respectively, and the plurality of sensing pads 140 are independently maintained at a certain distance and arranged in different positions on the substrate 120 in a rhombus manner.

[0024] In addition, the sensing pads 140 can be connected in series along a vertical direction or a horizontal direction respectively to form a plurality of sensing series, such as figure 1 As shown, the sensing pads 140 can be connected in series in the horizontal direction to form the sensing series X1-X7, or can be connected in series in the vertical direction to form the sensing series Y1-Y7. When the user touches a specific position on the...

Abstract

The invention discloses a touch panel, which comprises a base plate, a plurality of sensor pads, a plurality of dummy components and a plurality of electrostatic discharge components, wherein the sensor pads are arranged on the base plate; the sensor pads are distributed at intervals, and an insulating gap area is reserved between two adjacent sensor pads; each sensor pad comprises a side edge part and a corner part; the dummy components are respectively arranged in the insulating gap areas and respectively adjacent to the side edge parts of the sensor pads; and the electrostatic discharge components are coupled to the side edge parts of the sensor pads and bridged to vertical corresponding positions of the dummy components.

Description

technical field [0001] The present disclosure relates to a touch panel, and more particularly to an electrostatic discharge protection mechanism on a touch panel. Background technique [0002] Touch display devices have the advantages of convenient operation, fast response and space saving, and can provide users with more intuitive and convenient control methods. Therefore, they have become important input interfaces and are widely used in various consumer electronic products. Such as e-books, personal digital assistants, smart mobile communication devices, notebook computers and sales management systems and other electronic products. [0003] Generally, the touch panel realizes both touch and display functions by laminating a transparent touch sensing module on the display panel. With the rapid development of the above-mentioned touch hardware and its sensing accuracy, novel touch input interfaces have gradually attracted people's attention, gradually replacing traditional...
