Embodiment Construction

[0016] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0017] The invention provides a touch device and a touch method thereof. And more specifically, it uses a capacitive touch panel with a gradually increasing cross-sectional area as a single trace, and only needs a single sensor to accurately sense the moving direction and amount of movement of the finger relative to the capacitive touch panel. and movement speed.

[0018] see Figure 2A and Figure 2B . Figure 2A It is a schematic diagram of the appearance of the touch device 3 according to the first preferred embodiment of the present invention. Figure 2B for Figure 2A A functional block diagram of the touch device 3 in . Such as Figure 2A As shown, the touch device 3 of the present invention can be used to provide input signals to the computer device 2 . ...

Abstract

The invention discloses a touch device and a touch method thereof used for providing an input signal to a computer device. The computer device executes an application program according to the input signal. The touch device comprises a touch pad and a processing module. The touch pad is molded along a trace in general. The section area of the touch pad is increased gradually from a first end of the trace to a second end thereof. The processing module is used for providing the input signal to the computer device. When a finger moves on the touch pad, the processing module generates the input signal related to the finger according to the variable quantity of the capacitance value of the touch pad. The invention uses a capacitor type touch pad with the appearance of gradually increased section area as a single trace line to lessen the quantity of the trace line of the prior capacitor type touch pad so as to reduce the cost and simplify the application circuit.

Description

technical field [0001] The present invention relates to a touch control device and a touch control method thereof, in particular to a touch control device and a touch control method using a capacitive touch panel with a gradually increasing cross-sectional area as a single trace. Background technique [0002] At present, the world's technology is changing with each passing day, which is different from the past era of industrial and commercial society and rural society. With the advent of the information age and the gradual popularization of computer applications, the Internet is even more ubiquitous. Through personal computers to surf the Internet, all kinds of information are readily available. And general electronic products, such as: personal computer (Personal Computer, PC), notebook computer (notebook computer) and personal digital assistant (Personal Digital Assistant, PDA), etc., due to cost reduction, function improvement, volume reduction, weight reduction and more ...
