Abstract: A display device is provided and includes a display panel, a light source, a light source controller, and a timing controller. The light source is adjacent to the display panel. The light source controller is electrically connected to the light source. The timing controller is electrically connected to the light source controller and the display panel. The timing controller includes a decoding unit and first and second processing units. The first processing unit is electrically connected to the decoding unit and the display panel. The second processing unit is electrically connected to the decoding unit and the light source controller. The decoding unit provides a refresh signal to the first and second processing units so that the display panel refreshes displayed content in a first refresh sequence according to first refresh rates, and the light source refreshes brightness in a second refresh sequence according to second refresh rates.

Abstract: An ice shaver structure includes a worm shaft, an ice pressing tray installed at the bottom of the worm shaft for controlling ice block, a thread section formed on the worm shaft and engaged with a worm gear, a resisting mechanism installed on the worm gear and having a stopper fixed to an ice shaver and abutted against an axial surface of the worm gear, and a resilient device abutted against the stopper. The resilient device has a position-adjusting fixing element for determining an elastic force produced by the resilient device after being compressed, and the elastic force is acted on the stopper to push the stopper to press against the worm gear, such that the resilient device becomes a relative fixed end which is difficult to turn, so that the worm shaft can be driven by a motor to produced up-and-down displacements.
