Abstract: The disclosure provides a control method of a display driver. The control method includes receiving address information and defining an IC address according to the address information. The IC address includes n bits representing k zones, and n and k are positive integers. The control method further includes receiving the IC address, a black frame data signal and a pulse-width modulation (PWM) signal, and turning on or off the plurality of LEDs in the corresponding zone according to toggle of bit in the black frame data signal. Each bit in the black frame data signal indicates that a plurality of LEDs in a zone among the k zones are turned on or off.

Abstract: The present disclosure is directed to a semiconductor device. The semiconductor device includes a substrate, an insulating layer disposed on the substrate, a first conductive feature disposed in the insulating layer, and a capacitor structure disposed on the insulating layer. The capacitor structure includes a first electrode, a first dielectric layer, a second electrode, a second dielectric layer, and a third electrode sequentially stacked. The semiconductor device also includes a first via connected to the first electrode and the third electrode, a second via connected to the second electrode, and a third via connected to the first conductive feature. A part of the first via is disposed in the insulating layer. A portion of the first conductive feature is directly under the capacitor structure.
