35results about How to "Prevent charge leakage" patented technology

Display device and electronic device

An object of the invention is to provide a circuit technique which enables reduction in power consumption and high definition of a display device. A switch controlled by a start signal is provided to a gate electrode of a transistor, which is connected to a gate electrode of a bootstrap transistor. When the start signal is input, a potential is supplied to the gate electrode of the transistor through the switch, and the transistor is turned off. The transistor is turned off, so that leakage of a charge from the gate electrode of the bootstrap transistor can be prevented. Accordingly, time for storing a charge in the gate electrode of the bootstrap transistor can be shortened, and high-speed operation can be performed.

Micro-electro-mechanical module

A MEMS module that contains at least one integrated energy storage device whose discharge is minimized and controlled, so that power is available for system operation over longer periods of time. The MEMS module includes a device electrically coupled to the energy storage device for controlling charge transfers from the energy storage device while preventing charge leakage from the energy storage device. The controlling device includes a plurality of integrated MEMS switches that define open electrical paths that prevent charge leakage from the energy storage device through the MEMS switches, and are then operable to define closed electrical paths to allow charge transfers from the energy storage device, and preferably also allow charge transfers to the energy storage device, through the MEMS switches. The charge transfer can be utilized to power electronic circuits or store data in non-volatile digital memory.

Liquid crystal display panel, thin film transistor array and capacitor structure

A thin film transistor array comprising a plurality of common lines for providing the storage capacitance of pixels is provided. In particular, each of the common lines comprises a plurality of branches. Wherein, the common line and the branches thereof, and the pixel electrode constitute the storage capacitor. The branches are disposed at pixels where the luminance quality is bad. Therefore, the storage capacitance of the pixels can be enhanced without altering the aperture ratio of the pixels. Accordingly, the performance of the liquid crystal display panel can be improved.
