Abstract
A fingerprint sensing display panel includes a flexible substrate, a light sensing layer, a thin film transistor layer, an organic light-emitting diode layer, and a thin film encapsulation layer. The light sensing layer is disposed on the flexible substrate. Sensitivity of the light sensing layer set at high sensitivity. The organic light-emitting layer is disposed on the thin film transistor layer and configured to generate light according to an emitting signal from the thin film transistor layer. The thin film encapsulation layer is disposed on the organic light-emitting layer and configured to protect the organic light-emitting layer. When a user puts a finger on the fingerprint sensing display panel, the light sensing layer detects light generated from the organic light-emitting layer and reflected by the finger. By utilizing the fingerprint sensing display panel of the present disclosure, fingerprint recognition can be achieved without installing extra fingerprint recognizing components.
