Abstract: An AMOLED display driving device is switchable among plural frame rates, and includes a timing control unit, a panel driving unit, and an emission duty ratio control unit. Based on an input frame rate, the timing control unit changes the display time and V-blanking time in the frame period corresponding to the frame rate by extending V-blanking time, so that the display time in the frame period corresponding to the frame rate is equal to a standard display time. Based on the input frame data and frame timing, the panel driving unit drives an AMOLED display panel to display the input frame on the AMOLED display panel according to the changed display time and V-blanking time in the frame period corresponding to the frame rate. During the frame period corresponding to the frame rate, the emission duty ratio control unit applies plural emission pulses to the AMOLED display panel.

Abstract: A filtering film structure includes a film, a conductive layer and a dielectric layer. The film includes a plurality of holes. The conductive layer is disposed on the inner surface of the holes, and the dielectric layer is disposed on the conductive layer. When applying a voltage to the conductive layer, an electrical charge layer forms on the surface of the dielectric layer.

Abstract: A working fluid in cooperation with a solar thermal system comprises a heat conduction medium and a plurality of metal nano-particles mixed in the heat conduction medium. Each of the metal nano-particles includes a metal particle and a protection layer, and the protection layer is an oxide and covers the metal particle. A manufacturing method of metal nano-particles is also disclosed.

Abstract: A switch panel with an indicator is disclosed. The switch panel has a transparent region. There is a light source disposed in the switch panel for emitting light when turning off a switch body. A shape of the transparent region is projected onto the wall for forming a large area of indicating pattern, and this can replace a night light. The drawback of a luminous region in prior art which is limited to be on the switch body or on the switch panel is solved.
