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 Is a functional block diagram of the touch sensing device 200 capable of supporting one-dimensional and two-dimensional modes according to 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 206, and the host 206 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 back coordinate difference to the host 206. It can sense the movement of the finger 214 to produce a corresponding action. In the one-dimensional mode, the two-dimensional coordinates (x, y) are transmitted to the coordinate converter ...

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, lightness, and low cost, touch panels have been widely used in various electronic products to replace the original input devices. The current touchpad has a two-dimensional mode and a one-dimensional mode. Figure 1A and Figure 1B The sensors 100 and 101 of the two-dimensional touch panel of two common shapes have a plurality of horizontal direction sensing lines 102 and vertical direction sensing lines 104. When a finger touches the two-dimensional touchpad, the sensing lines 102 and 104 of the touched position transmit information to the host connected to the two-dimensional touchpad, so that the coordinates of the touched position are known. When the two-dimensional touchpad moves, the host...
