Abstract

The invention discloses a display screen gesture control circuit and method based on capacitive sensing. The circuit includes a display screen and sensors arranged around the display screen. The sensors are arranged in strips, and a shielding layer is provided around each sensor. Multiple sensors output sensing signals to the detection circuit; the ground terminal of the display screen is disconnected from the ground, and the ground terminal of the display screen, the sensor and the shielding layer are all connected to the oscillating signal source. The method comprises the detection circuit detecting the signal output by the sensor, and determining the current working sensor; loading an oscillating voltage signal to the non-working sensor, so that the non-working sensor and the current working sensor are loaded with the voltage signal Synchronous oscillation; the detection circuit detects the signal output by the currently working sensor, and determines the gesture according to the change of the signal output by the currently working sensor. The invention can accurately detect the change of the gesture of the user, and the production cost is low.

Description

technical field [0001] The invention relates to the field of gesture recognition, in particular to a display gesture control circuit based on capacitive sensing and a control method realized by using the circuit. Background technique [0002] Today's electronic devices are becoming more and more intelligent. As people's requirements for electronic devices are getting higher and higher, the gesture recognition function of electronic devices is becoming more and more important. Most existing electronic devices recognize gestures by taking pictures of the user's gestures with a camera, and then recognizing the images to identify the changing process of the user's hand movements based on the images, thereby recognizing the user's gestures. [0003] However, the recognition of user gestures through images and videos captured by the camera device puts forward high requirements on the image processing and image recognition capabilities of electronic equipment, and when electronic e...
