Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] refer to Figure 1-2 , a method for realizing a pressure touch panel, including a realization device, the realization device includes a piezoresistive film 100, a data acquisition matrix 200 and a processor 300, the piezoresistive film 100 is divided into an outer surface layer 101 and an inner surface layer 102, and the outer surface layer 101 is in contact with the touch object. The piezoresistive film 100 uses an insulating substrate, which is a flex...

Abstract

The invention discloses a pressure touchpad implementation method which comprises the following steps: an inner surface layer of a piezoresistive film is tightly attached to the surface of a data acquisition matrix, and electrodes of the data acquisition matrix are respectively connected to a processor IO; the processor adds driving voltage through the driving electrodes, AD sampling is conductedon each set of electrodes through the sensing electrodes, and the resistance value between each electrode pair is derived from sampling data through operation. And the pressure of each point is calculated according to the characteristics of the piezoresistive material, and thus finally forming a frame of pressure matrix. The number and the positions of the contacts can be calculated according to the pressure matrix, pressure data are carried, and the moving condition and the pressure change condition of each contact can be calculated by combining the multi-frame pressure matrix, so that various gestures of the touchpad can be judged, and more rich gestures based on pressure can be realized. The pressure dimension information is added, operation is enriched, the using environment problem issolved, application in various extremely severe environments is met, and the cost of an existing pressure touch scheme is reduced.

Description

technical field [0001] The invention relates to the technical field of touch panels, in particular to a method for realizing a pressure touch panel. Background technique [0002] At present, the touchpad products on the market are mainly used for notebook computers, which are basically the standard configuration of notebook computers. At the same time, there are also some independent touchpad products, which can be used for products that do not have a touchpad but require touch operation. , such as tablets, etc., and groups that have higher requirements for touchpads. With the development of human-computer interaction technology, consumers are paying more and more attention to operating experience, among which multi-touch and pressure touch are the main technical development directions. [0003] At present, most touch panels are implemented with capacitive touch technology. Although they can support multi-touch, they cannot support pressure and cannot distinguish changes in...
