Abstract
A fingerprint detector includes a driving circuit, a sensing array, a gate driving circuit, a reading circuit, a first light emitting structure and a second light emitting structure. The first and the second light emitting structures are isolated from one another. The driving circuit provides power to the first and the second light emitting structures. The sensing array includes a plurality of first light sensing elements disposed under the first light emitting structure and a plurality of second light sensing elements disposed under the second light emitting structure. Each of the light sensing elements generates a light sensing voltage according to scanning light received. The gate driving circuit drives a plurality of rows of the light sensing elements sequentially through a plurality of gate lines. The reading circuit sequentially or synchronously reads the light sensing voltages generated by light sensing elements in different columns of a same row driven by the gate driving circuit.
