Abstract

The invention discloses a scanning circuit and a display panel. The scanning circuit includes: a plurality of scanning circuit units, including a plurality of first scanning circuit units and a plurality of second scanning circuit units; a plurality of multiplexing circuit units; The first scanning circuit units are sequentially cascaded; the multiplexing circuit unit and the second scanning circuit unit are arranged alternately in sequence, and the control signal input terminal is used for outputting the shift signal output terminal of the first scanning circuit unit at the N-1 stage At the same time as the effective signal, the control selection signal output terminal is turned on with the third input terminal, and when the shift signal output terminal of the first scanning circuit unit of the N-1 stage outputs a valid signal, the control selection signal output terminal is connected to the first input terminal. The terminal is turned on, and N is an integer greater than or equal to 2. The present invention can solve the problem of wasted scanning time and power consumption of the scanning circuit.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a scanning circuit and a display panel. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. In the existing display device with fingerprint identification function, the fingerprint identification module generally detects the light irradiated to the fingerprint identification unit through the touch body (such as a finger), that is, the ridges and valleys o...
