Problems solved by technology

However, when an object presses the upper cover of the resistive touch panel, the upper cover is deformed and takes a long time to return to its original shape, and the resistive touch panel can only detect single-touch
Although the capacitive touch panel does not have the defects of the above-mentioned resistive touch panel, since the capacitive touch panel detects the capacitance formed between the touch object such as a finger and the touch device, the touch object must be Conductor, if the touch object is an insulator, the touch device cannot detect the touch action

Embodiment Construction

[0020] Certain terms are used in the specification and subsequent claims to refer to particular elements. It should be understood by those skilled in the art that manufacturers may use different terms to refer to the same component. This description and subsequent patent applications do not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for distinction. The "comprising" mentioned in the entire specification and subsequent claims is an open-ended term, so it should be interpreted as "including but not limited to", which will be described here first.

[0021] Fig. 1 shows a schematic cross-sectional view of the structure of the first preferred embodiment of the present invention, please refer to Fig. 1 . Firstly, the touch device 100 includes a substrate 110 , which may be a planar or non-planar substrate, such as glass or a flexible transparent material. At least one touch area 120 is disposed on ...

Abstract

The invention discloses a touch device and a detection method of the touch device. The touch device comprises a plurality of piezoelectric induction units and a plurality of signal wires, wherein the piezoelectric induction units are arrayed in a touch control area of a substrate, and the signal wires are located on the substrate and electrically connected with the piezoelectric induction units. According to the touch device, mechanical deformation can be transformed to electrical signals, signals on the touch device can be detected without additional driving voltage, and therefore the touch device is low in energy consumption and capable of saving energy.

Description

technical field [0001] The invention provides a touch device and a detection method thereof, especially a piezoelectric touch device, which can detect the position of a single point or a multi-point touch by a plurality of piezoelectric sensing units arranged on a substrate. Background technique [0002] The requirements for the size of electronic products in the market are developing in the direction of thinner, lighter and smaller. Therefore, many electronic products no longer design keyboard input devices that take up a lot of space, but try to replace the keyboard with other input mechanisms, in which the touch device is integrated into the electronic product. The practice of touch is the most popular input technology at present, so touch devices are widely used in various electronic products, such as mobile phones, personal digital assistants and satellite positioning systems. [0003] At present, common touch panels are mainly capacitive for multi-touch and resistive f...
