Problems solved by technology

Although this one-dimensional touchpad can clearly determine the positive and negative directions, it cannot provide a variety of functions like a two-dimensional touchpad, such as handwriting recognition. If you want to add additional functions, you must add additional buttons or other functions. input device, which will increase the cost

Embodiment Construction

[0054] image 3 It is a functional block diagram of the touch sensing device 200 supporting one-dimensional and two-dimensional modes of the present invention, Figure 4 is a schematic diagram of the operation. When the finger 214 touches the panel 212, the sensor 202 senses the position of the finger 214 on the panel 212 and sends a two-dimensional signal Sd to the two-dimensional coordinate processor 204 to generate two-dimensional coordinates (x, y). In the two-dimensional mode , the two-dimensional coordinates (x, y) are directly transmitted to the host computer 206, and the host computer 206 thus knows the current position of the finger 214. When the finger 214 moves on the panel 212, the two-dimensional coordinate processor 204 sends the front and rear coordinate difference to the host computer 206, It can sense the movement of the finger 214 and generate corresponding actions. In the one-dimensional mode, the two-dimensional coordinates (x, y) are sent to the coordina...

Abstract

The present invention relates to a touch sensing device capable of supporting one-dimensional and two-dimensional modes and its control method. It is characterized by that it utilizes an inductor with a first direction induction line and a second direction induction line to induct the position of an object on said touch sensing device and output a first signal; under said two-dimensional mode a two-dimensional coordinate processor can be used for outputting a two-dimensional coordinate according to said first signal; under said one-dimensional mode a coordinate converter can be used for producing a second signal according to said first signal or two-dimensional coordinate; and an one-dimensional coordinate processor can be used for outputting one-dimensional coordinate according to said second signal.

Description

technical field [0001] The present invention relates to a touch sensing device, in particular to a touch sensing device capable of supporting one-dimensional and two-dimensional modes and a control method thereof. Background technique [0002] Recently, due to the advantages of simplicity, portability and low cost, the touch panel has been widely used in various electronic products to replace the original input device. The current touchpad has two-dimensional mode and one-dimensional mode. Figure 1A and Figure 1B The sensors 100 and 101 are two common shapes of two-dimensional touch panels, which have a plurality of horizontal sensing lines 102 and vertical sensing lines 104 . When a finger touches the two-dimensional touch panel, the sensing lines 102 and 104 at the touched position transmit information to the host computer connected to the two-dimensional touch panel, thereby knowing the coordinates of the touched position. When moving on the two-dimensional touchpad, ...
