Dual-mode touch input apparatus and mode-switching method for the same
First Claim
1. A dual-mode touch input apparatus, mounted in an electronic apparatus, having a 1-D input mode and a 2-D input mode, comprising:
- a touch pad as an interface between the dual-mode touch input apparatus and a user;
a flexible printed circuit board for detecting a position of a user touch and issuing a detection signal, further having a plurality of sensors and being located under said touch pad; and
a control chip for receiving the detection signal, determining whether the dual-mode touch input apparatus is at the 1-D input mode or the 2-D input mode, and producing a cursor signal in response to the user touch to control movement of a cursor on a screen of the electronic apparatus.

Abstract
A dual-mode touch input apparatus, mounted in an electronic apparatus and capable of arbitrarily switching around a 1-D input mode and a 2-D input mode, comprises a touch pad, a flexible printed circuit board (FPCB) and a control chip. The FPCB is used for detecting a position of a user touch and issuing a detection signal to the control chip. The control chip is used for determining whether the dual-mode touch input apparatus is at the 1-D input mode or the 2-D input mode and producing a cursor signal in response to the user touch to control movement of a cursor on a screen of the electronic apparatus.

5. A mode-switching method for a dual-mode touch input apparatus, the dual-mode touch input apparatus being mounted in an electronic apparatus and further having a touch pad, a flexible printed circuit board (FPCB) and a control chip for determining whether the dual-mode touch input apparatus is at a 1-D input mode or a 2-D input mode, the mode-switching method comprising the steps of:
-
(a) the FPCB detecting a detection signal and further forwarding the detection signal to the control chip; (b) the control chip receiving the detection signal and initiating the dual-mode touch input apparatus at the 2-D input mode; (c) the control chip receiving a switch signal and then switching the dual-mode touch input apparatus to the 1-D input mode; (d) detecting a direction signal and scrolling upward a screen of the electronic apparatus if the direction signal is a positive signal; and (e) scrolling downward the screen if the direction signal is a negative signal. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
