Embodiment Construction

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030] The invention discloses a finger touch positioning device and a positioning method, which realize precise finger touch positioning in a low-cost manner by making full use of the vibration wave generated by the contact between the finger and an object and the vibration wave sensor. Here, the present invention relates to a finger touch positioning device and method for a single finger.

[0031] The finger touch positioning device of the present invention includes a solid-state panel, at least three vibration wave sensors and a posit...

Abstract

The invention discloses a finger touch positioner and a method, belonging to the technical field of touch. The finger touch positioner comprises a solid panel, at least three oscillatory wave sensors and a positioning recognition and treatment unit, wherein the solid panel correspondingly generates and transmits oscillatory wave after contacting with fingers; the oscillatory wave sensors are respectively stuck on the solid panel so as to convert the oscillatory wave generated by contacting fingers with the solid panel into electric signals; and the positioning recognition and treatment unit calculates to obtain the contact position of the finger on the solid panel by receiving the electric signals of the oscillatory wave sensor and combining the physical position information of the oscillatory wave sensor. The invention fully utilizes the oscillatory wave generated by contacting fingers with the solid panel to realize precise positioning of fingers by low cost.

Description

technical field [0001] The invention belongs to the field of touch technology, in particular to a finger touch positioning device and method. Background technique [0002] With the wide application of touch technology, people feel the convenience of finger control more and more, especially the introduction of mobile phones and tablet computers by Apple in the United States, which promotes people's exploration of new technologies. [0003] The current popular capacitive touch screen can easily realize single-finger or multi-finger operation, but the cost is high, the positioning accuracy is easily affected by liquid, and the touch device must be placed in front of the display screen, which will affect the display brightness of the display screen. For the relatively cheap resistive touch screen, finger operation can also be realized, but it is easy to be damaged, and it is also necessary to arrange the touch device in front of the display screen to affect the display brightnes...
