    摘要: The present disclosure provides a signal collecting circuit, a signal collecting method and an electronic device. A signal collecting circuit includes: a bias voltage wire, multiple fingerprint pixel circuits and a photocurrent collecting module. Each fingerprint pixel circuit includes a photoelectric conversion unit connected to the bias voltage wire and configured to output a photocurrent signal to the bias voltage wire when light hits the photoelectric conversion unit. A photocurrent collecting module is connected to the bias voltage wire and configured to collect the photocurrent signals output by at least part of the photoelectric conversion unit through the bias voltage wire.

    摘要: A display panel includes a display region with a thin film transistor and a plurality of data lines and a non-display region. Thin film transistor includes a gate, a source region and a drain region, data lines include a plurality of first type data lines which are located at an edge of display region and close to a side of non-display region. First type data line includes a first sub-data line extending in a first direction, a conductive connection line extending in a second direction and a second sub-data line extending in a first direction. First sub-data line is connected with source region or drain region. A first insulating layer is between conductive connection line and first sub-data line. A second insulating layer is between second sub-data line and conductive connection line, and second sub-data line is closer to a central axis of display panel than first sub-data line.
