Abstract: An in-cell optical sensing display panel includes a pixel array, a plurality of first optical sensors and a plurality of second optical sensors. The pixel array is disposed in an active area of the in-cell optical sensing display panel, and the active area includes a first region and a second region which surrounds the first region. The sensor array is disposed in the first region of the active area and is configured to sense a fingerprint of a finger touching a surface of the in-cell optical sensing display panel. The second optical sensors are disposed in the second region of the active area and are configured to sense ambient light, and the second optical sensors are not to be used for fingerprint sensing.
