Abstract

The invention provides a piezoelectric type touch panel. The piezoelectric type touch panel comprises a plurality of piezoelectric induction units and a plurality of signal wires. The piezoelectric induction units are arranged on one side of a substrate. Each piezoelectric induction unit comprises a grounding layer, a signal layer and a piezoelectric material layer, wherein the piezoelectric material layer is arranged between the grounding layer and the signal layer, is electrically connected with the grounding layer and the signal layer and is made of a solid solution formed by doping 3d transition metal into zinc oxide. The signal wires are electrically connected with the signal layers of the piezoelectric induction units respectively.

Description

technical field [0001] The present invention relates to touch panels, and more particularly to piezoelectric touch panels. Background technique [0002] The size requirements of electronic products in the market are developing in the direction of thinner, lighter and smaller. Therefore, many electronic products, such as mobile phones, personal digital assistants and satellite positioning systems, no longer design keyboard input devices that take up a lot of space. Input devices are integrated into various electronic products. [0003] Currently, capacitive touch panels are the mainstream of touch panels capable of supporting multi-touch. However, what the capacitive touch panel detects is the capacitance between the two-axis sensing electrodes of the touch panel, or the capacitance between the two-axis sensing electrodes of the touch panel and the ground respectively. (such as a finger) the amount of capacitance change produced before and after the impact. Therefore, the ...
