Benefits of technology

The present invention is an adaptive touch panel system and method that can automatically adjust the settings of the panel based on the current operating environment. This results in a good touch function in various operating environments.

Problems solved by technology

Or, when an environmental temperature of the operating environment of the touch panel is excessively high or excessively low, noises may easily occur in the touch panel to cause poor touch quality.
Or, when there is liquid (for example, water) on a surface of the touch panel, since the liquid is conductive, the touch panel is likely to falsely report a touch point.
One of conventional solutions is to increase a sensing threshold, but the sensitivity may be decreased to bring troubles in use.

Abstract

An adaptive touch panel system and an adaptive method thereof are provided. The adaptive touch panel system includes a touch panel and an environment sensing device. The touch panel includes a touch sensor and a control device. The touch sensor senses a touch event and correspondingly outputs touch raw data. The control device includes a plurality of setting modes. The plurality of setting modes include a general setting mode and at least one special setting mode. The environment sensing device senses a current operating environment of the touch panel and generates at least one environmental physical parameter. The control device is configured to correspondingly select one of the plurality of setting modes according to the at least one environmental physical parameter, set the touch sensor according to the selected setting mode, and analyze the touch raw data to generate touch data.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 108127080, filed on Jul. 30, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDField of the Invention[0002]The present invention generally relates to a touch panel system, in particular, to a touch panel system adapted to an environmental change and an adaptive method thereof.Description of Related Art[0003]Along with improvement, development and cost reduction of touch technologies, touch panels have been quite popularized and usually integrated into various electronic products such that users may intuitively control and operate the electronic products. Existing common touch panels include capacitive touch panels, resistive touch panels and optical touch panels. For example, in a capacitive touch panel, since a position of a touch point is determined by sensing ...
