The single-layer mutual-capacitance touch panel has the advantages that the problem of floating can be effectively solved by the aid of the single-layer mutual-capacitance touch panel, and the single-layer mutual-capacitance touch panel is simple in structure, is integrally lightened and thinned and has good touch hand feel.

Description

[technical field] [0001] The invention relates to a touch panel, in particular to a single-layer mutual-capacitance touch panel with high touch accuracy and better solution to the levitation problem. [Background technique] [0002] The technology development of the touch panel is very diverse. At present, the more common technologies include resistive, capacitive and optical. Among them, the capacitive touch panel has high accuracy, multi-touch, high durability and high touch control. Resolution and other characteristics have become the mainstream touch technology used in mid-to-high-end consumer electronics products. [0003] The operation principle of the capacitive touch panel is to use the sensing electrodes to detect the capacitance change of the touch point, and use the connecting wires connecting the electrodes in different directions to transmit the signal back to complete the positioning. In recent years, with the touch sensing With the rapid development of technol...

Problems solved by technology

[0004] With the rapid development of the touchpad, there have been some unacceptable problems, such as the floating problem of the touchpad, when the finger is close to the touchpad, multiple touch points are generated, which affects The normal touch function reduces the user experience. The conventional solution is to increase the coupling capacitance between the driving and sensing electrodes. In this case, the production cost and operating power will be increased, which is not conducive to normal technological development. It is the normal development direction of the touch panel to reduce the inherent capacitance between the finger and the sensing and driving without affecting the mutual capacitance between the electrodes, and finally realize normal touch without generating multiple touch points. Based on this, this field The technicians have carried out a lot of research and development work, and have also achieved outstanding results
