Abstract: A cholesterol liquid crystal display device includes a liquid crystal display panel and a liquid crystal driving unit. The liquid crystal display panel has a plurality of pixels. The liquid crystal driving unit applies row driving voltages and column driving voltages to a designated pixel according to the input signal. After the input signal is transmitted, the liquid crystal driving unit activates the power-down signal within a certain period of time to reduce the row driving voltage and the column driving voltage applied to the specified pixel. Thereby, the crosstalk phenomenon on the cholesteric liquid crystal display device can be improved.

Abstract: The present invention relates to a driving method of a cholesteric liquid crystal display. It includes the steps in the following: driving each scan line by a dynamic driving scheme (DDS) including an Evolution phase; refreshing a frame of the cholesteric liquid crystal display by a full refresh mode, each scan line driven N times during the Evolution phase in the full refresh mode; and refreshing a part of the frame by a partial-refresh mode, each scan line driven M times in the Evolution phase in the partial-refresh mode, wherein M is greater than N.

Abstract: A miniature fluid transportation device is provided and includes a convergence component, a valve component, an outlet plate and a plurality of fluid transportation actuation components. The plurality of fluid transportation actuation components are disposed on the convergence component so as to transport the fluid to the convergence component. The convergence component guides the fluid transported by the fluid transportation actuation components to the outlet plate through the valve component. The outlet plate guides the fluid from different transportation actuation components back to the convergence component by a separation guiding block. The fluid is converged in a convergence central slot of the convergence component and is discharged out through a collection channel of the outlet plate. Consequently, the problem of interference owing to the convergence of the fluid transported by different fluid transportation actuation components can be avoided.

When the actuator is driven, through the structure of misalignment of the first orifices and the valve openings, the valve body is operated to open a flow path when an airflow is in a forward direction, and the valve body is operated to seal the flow path when the airflow is in a reverse direction.

Abstract: A micro pump having noise-reduced pressure-releasing structure includes a convergence plate, a valve sheet, a chamber plate, and a micro pump. The convergence plate has a convergence outlet and a discharge outlet. The valve sheet has a valve hole and a discharge recessed portion. The chamber plate has a recessed hole, a fluid determine hole, fluid through holes, and a receiving trough. The micro pump is in the receiving trough. During operation of the micro pump, the fluid is firstly transmitted to the fluid through hole and the fluid determine hole to push the valve sheet, and the fluid determine hole pushes the discharge recessed portion to block the discharge outlet. Then, since the pressure of the fluid at the fluid through hole pushes the valve sheet, the fluid flows through the valve hole so as to be discharged out from the convergence outlet.
