Abstract:
A self-luminous display pixel is provided, including: a self-luminous circuit including a self-luminous device, the self-luminous device including a bottom electrode layer; wherein the bottom electrode layer includes a light blocking layer; and the self-luminous display pixel further includes an optical fingerprint sensing circuit, the optical fingerprint sensing circuit includes a first TFT device and a photosensitive device, and a channel layer of the first TFT device is disposed right under a portion of the bottom electrode layer. A fingerprint sensing function can be realized by the self-luminous display pixel, and an overall structure of the self-luminous display pixel can be optimized.
