1. An in-cell optical sensing display panel, comprising:
a pixel array disposed in an active area of the in-cell optical sensing display panel, wherein the active area comprises a first region and a second region, and the second region surrounds the first region;
a sensor array, disposed in the first region of the active area, comprising a plurality of first optical sensors and configured to sense a fingerprint of a finger touching a surface of the in-cell optical sensing display panel; and
a plurality of second optical sensors, disposed in the second region of the active area and configured to sense ambient light and not to be used for fingerprint sensing.
