The disclosure provides a driving method. The driving method includes following steps. During a normal scan period, a part of drivers provide first control signals generated according to a first clock frequency to target gate lines included in a part of gate line groups. During a high scanning period, the part of drivers provide second control signals generated according to a second clock frequency to residual gate lines included in the part of gate line groups.

Image sensor and driving method thereof

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.

Fingerprint detector

A stereoscopic display and a driving method are disclosed herein. The stereoscopic display includes a sensor, a barrier cell, and a control unit. The sensor is configured to detect a user to generate a sensing signal. The barrier cell is configured to generate a 3D image with a 2D image. The barrier cell includes barrier pitches disposed in parallel. Each of the barrier pitches includes switchable barrier units. The control unit is configured to generate control signals to adjust the switchable barrier units according to the sensing signal, so as to make at least one of the switchable barrier units of each of barrier pitches form a shading zone, to make the switchable barrier units disposed at the two adjacent sides of the shading zone form a gray level zone, and to make the rest of the switchable barrier units in the same barrier pitch form a photic zone.
