Abstract

The invention provides an electronic device. The touch display panel comprises a pixel array and a plurality of fingerprint sensing pixels. The fingerprint sensing pixel is embedded in the pixel array and located in a non-light-emitting area outside the position where the sub-display pixel is located. The display driving circuit is coupled to the plurality of display data lines through the first pins and drives the sub-display pixels to display the image picture. The fingerprint sensing circuit is coupled to the sensing data line through the second pin and receives a fingerprint sensing signal of the fingerprint sensing pixel.

Description

technical field [0001] The invention relates to a device, in particular to an electronic device with a fingerprint sensing function. Background technique [0002] In recent years, fingerprint recognition technology has been widely used in various electronic devices to provide various identity login or identity verification functions. At present, the existing technical principles of fingerprint recognition include optical, capacitive, thermal and ultrasonic. In this regard, since the above-mentioned fingerprint sensors are installed in the electronic device, the fingerprint sensor usually needs to occupy a part of the device volume of the electronic device, wherein a general fingerprint sensor can be installed or hung on the bottom of the screen, the Home button or the body of the electronic device, for example. back etc. In other words, the general fingerprint sensor will increase the overall device volume or thickness of the electronic device, and further increase the man...
