Abstract

The invention provides an electronic device with a fingerprint sensing function. The electronic device comprises a touch display panel and an integrated chip. The touch display panel comprises a pixelarray. The integrated chip is electrically connected to the touch pixel array. The integrated chip comprises a fingerprint sensing circuit and a display driving circuit. The fingerprint sensing circuit and the display driving circuit are electrically connected to the plurality of display data lines and the sensing data lines through the same pin. The plurality of display data lines are electrically connected to the plurality of color sub-pixels of the pixel array respectively. The sensing data lines are electrically connected to a plurality of fingerprint sensing pixels of the pixel array. The plurality of color sub-pixels are a plurality of liquid crystal display pixels.

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 identification 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 ...
