Problems solved by technology

When the capacitive touch panel operates externally or electrically, excessive charges are easily accumulated at the two ends 151 and 152 of the bridge wire 150, causing the bridge wire 150 to be blown at the two ends 151 and 152.
The whole row of diamond-shaped electrodes located at the blown place is useless, thus reducing product reliability and sensing accuracy

Abstract

The invention discloses an electrode array of a touch panel. The electrode array of the touch panel comprises a plurality of rhombus electrodes, a plurality of dumb-bell-type electrodes and a plurality of bridging lines; the plurality of rhombus electrodes are ranked along a first direction, and are connected with one another at the first direction; the plurality of dumb-bell-type electrodes are ranked along a second direction, and each dumb-bell-type electrode is provided with a first expanding part, a second expanding part and a narrow part, wherein each rhombus electrode is arranged between two adjacent dumb-bell-type electrodes along the second direction; and the plurality of bridging lines are respectively used for being electrically connected with the two first expanding parts and the two second expanding parts of the two adjacent dumb-bell-type electrodes. According to the invention, through the dumb-bell-type electrodes, the product reliability is improved.

Description

technical field [0001] The present invention relates to a touch panel, in particular to an electrode array of a touch panel. [0002] Background technique [0003] In recent years, the application of capacitive touch panels in consumer electronics products has become the mainstream design in the market, and improving the sensing characteristics of touch panels is also one of the important development goals at this stage. Electrostatic discharge (ESD) is a problem that current touch panels need to improve. When a user operates a capacitive touch product, the function of the touch panel is damaged due to electrostatic discharge (ESD). This problem has become the focus of attention and improvement of various manufacturers. [0004] During the process or use of capacitive touch panels, static charges are often generated due to friction or other reasons. Excessive static charges can easily lead to electrostatic discharge and release electric energy. During the process, the touc...
