The invention relates to a signal driving system for a display. The signal driving system comprises: a signal controller, a flexible connector and a plurality of driving devices. The signal controller is used to produce a first control signal. The flexible connector is connected to the signal controller, and used to receive the first control signal. One of the driving devices is connected to the flexible connector. The driving devices connect in cascade. Each driving device comprises a data input port, a data output port and a driving signal output port. The data input port receives the first control signal or a second control signal. The data output port outputs the second control signal. According to the first control signal or the second control signal, the driving signal output port transmits a driving signal. The signal driving system of the invention can make the data output port of the driving device transmit the second control signal to the next driving device. Therefore, the signal driving system of the invention can resolve the problem between different control signals of different circuit interfaces. Besides, the signal driving system of the invention has the advantage of processing the first control signal in the signal controller and transmitting the second control signal between the driving devices.

Signal driving system for a display

A driving circuit for improving display quality of a liquid crystal display (LCD) device. The driving circuit is installed on a surface of a glass substrate of the LCD device and includes a bus line and a plurality of driving IC chips. The driving circuit also includes a plurality of impedance matchers between the bus line and each of the driving IC chips so as to make each driving IC chip obtain equal input voltage from the bus line.

Driving circuit of a liquid crystal display device

A driving circuit of a liquid crystal display device includes a substrate, at least two driver integrated circuit (IC) chips located on the substrate, and an impedance device electrically connected between the two driver IC chips for reducing a difference between respective input voltages being input into the two driver IC chips.

A display apparatus with a time domain multiplex driving circuit includes a first scan line, a first data line perpendicular to the first scan line, a first pixel and a second pixel which are set on different sides of the first data line and coupled to the same data line, a first switching device and a second switching device set in the first and second pixel respectively. The first switching device is for selectively transmitting a pixel signal from the data line to the first pixel and the second switching device is for selectively transmitting a pixel signal from the data line to the second pixel. When the pixel signals of equal magnitude are individually applied to the first and second pixels, the feed-through voltages of the first and second pixels are substantially equal.

A liquid crystal display (LCD) having reduced flicker includes a plurality of signal lines, a plurality of scanning lines, and a plurality of pixels. Each pixel includes a liquid crystal cell having a pixel electrode, a storage capacitor, and a switching transistor. The switching transistor includes a gate electrode connected to one of the scanning lines, a drain electrode connected to one of the signal lines, and a source electrode connected to the pixel electrode. An overlapping region is between the gate electrode and the source electrode. The area of the overlapping region increases by increasing the distance between an input end of the scanning line corresponding to the overlapping region and the pixel electrode corresponding to the overlapping region.
