Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] In the embodiment of the present invention, the position detection sensing electrode layer and the pressure detection sensing electrode layer are arranged on the touch sensor at the same time, and the position and number information of the touch point is detected through the position detection sensing electrode layer, and the touch point is detected through the pressure detection sensing electrode layer The force size information of the touch detection system can not only detect the pressure, but also accurately detect the position of the key.

Abstract

The invention is suitable for the technical field of touch sensors and provides a touch detection system and a detection method thereof. A position detection sensing electrode layer and a pressure detection sensing electrode layer are simultaneously arranged on the touch sensor, and position and quantity information of a touch point is detected through the position detection sensing electrode layer and stress information of the touch point is detected through the pressure detection sensing electrode layer, thus the touch detection system can not only be used for detecting the pressure but also used for detecting the position of a key accurately, realizes the effect of multi-finger pressure detection, and can be suitable for the technology of touch screen keyboards.

Description

technical field [0001] The invention belongs to the technical field of touch sensors, and in particular relates to a touch detection system and a detection method thereof. Background technique [0002] The feature of the multi-finger pressure detection technology is that the user puts multiple fingers on the keys of the mechanical keyboard at the same time during operation, and the keyboard responds only when a certain finger presses the key with force. In the same way, if there are multiple fingers touching a touch screen keyboard, the chip will detect all the touching fingers, and only when a certain finger exerts force, it is considered that there is a key operation. [0003] However, due to the unsatisfactory response of the current touch detection technology to the key pressure, the touch screen keyboard can only recognize the touching finger, but cannot distinguish the pressure used by the finger. Therefore, when two or more keys exist, the current The technology is n...
