Abstract: 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.

Abstract: A method for driving an LCD monitor is disclosed. The LCD monitor includes a voltage selection unit used for outputting a plurality of driving voltages according to display data, and a plurality of output buffers each electrically connected to the voltage selection circuit and a corresponding pixel. In the beginning, an output port of each output buffer approaches voltage at an input port. Then, the output ports of the driving units, which approach the same input voltage, are electrically connected to have an average voltage. In addition, the LCD monitor further includes a timing controller for controlling operation of the output buffers. When output ports of the output buffers, which approach the same input voltage, are electrically connected, the output buffers are turned off for saving power.
