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: An outsole for shoes includes a top part and a bottom part, the top toe portion of the top part and the bottom toe portion are glued to each other and a chamber is defined between the top and bottom heel portions of the top and bottom part. The top heel portion has multiple top protrusions extending from underside thereof and the bottom heel portion has multiple bottom protrusions extending from a top surface thereof. The top and bottom protrusions are located in the chamber. The respective distal ends of the top and bottom protrusions are glued to each other. The deformation of the top and bottom protrusions absorbs shocks from the ground.
