Example Embodiment
[0072] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0073] In the embodiment of the present invention, the driving electrode or / and the receiving electrode are grouped, and each group shares the same lead and is connected to the same bonding pad (PAD), thereby reducing the number of leads and bonding the number of PADs, thereby improving the single-layer mutual capacitance touch screen The bonding yield, linearity, accuracy, and reliability of the bonding pad, in addition, also reduce the area and cost of the flexible circuit board (FPC) connected to the bonding PAD.
[0074] In addition, the "second electrodes arranged in mirror symmetry" menti...
