Embodiment Construction

[0031] A specific embodiment according to the present invention is a self-capacitive touch system, the electrode configuration of which is as follows Figure 4A shown. A plurality of electrodes whose planar shapes are approximately right triangles are divided into upper and lower groups in the Y direction to form two different sensing areas 410 , 420 . In this embodiment, each electrode is connected to a sensor for detecting the change in capacitance. In other words, each of the sensing areas 410, 420 is monitored by a plurality of sensors. In order to keep the drawing clear, Figure 4A Only sensors 43A-43D and 44A-44D to which electrodes 41A-41D and electrodes 42A-42D are connected are shown.

[0032] The monitoring results generated by these sensors will be transmitted to the control module 45 for the control module 45 to determine the location where the user touches. When a receiving contact is formed in the first sensing area 410 , the control module 45 first determine...

Abstract

The invention provides a touch system and a signal processing method thereof. The signal processing method is used for matching a touch panel. The touch panel comprises a first sending area and a second sensing area. The first sensing area is monitored by at least one first sensor for generating a first monitoring result, and the second sensing area is monitored by at least one second sensor for generating a second monitoring result. The signal processing method comprises that whether a touched point formed in the first sensing area is adjacent to the second sensing area is judged. If the touched point is adjacent to the second sensing area, position information of the touched point is generated according to the first monitoring result and the second monitoring result.

Description

technical field [0001] The invention is related to touch systems, and is especially suitable for touch systems including multiple sensing areas. Background technique [0002] With the advancement of technology, the operation interfaces of various electronic products have become more and more user-friendly in recent years. For example, through a touch screen, users can directly operate programs and input messages / texts / patterns on the screen with their fingers or a stylus, saving the trouble of using input devices such as keyboards or keys. Actually, the touch screen is usually composed of a sensing panel and a display disposed behind the sensing panel. The electronic device judges the meaning of the touch according to the position touched by the user on the sensing panel and the picture displayed on the display at that time, and executes the corresponding operation result. [0003] Existing capacitive touch technologies can be classified into two types: self-capacitance an...
