摘要： A liquid crystal display (LCD) and circuit architecture thereof are proposed. Power signal lines, data signal lines, and control signal lines are mounted on a printed circuit board (PCB) and a thin film substrate. The thin film substrate is connected to a LCD panel by using a COF bonding. These circuits can be transferred onto a conductive glass of the panel and subsequently onto source driver chips of the thin film substrate of the COF. Therefore, a position which needs the least time for power signal lines, data signal lines, and control signal lines to transmit to all of the circuits of the panel on the PCB can be calculated in order to achieve the best design.

The LCD device includes a plurality of pixel units which are arranged in an array of rows, first scan lines, second scan lines, and switch units. The pixel units of each row are divided into first pixel units and second pixel units.

摘要： Disclosed are a LCD device and a driving method thereof. A counting control unit is used for outputting control signals periodically. A determining unit receives the video signal and the control signal and determines if it is necessary to determine the video signal of a current frame is identical with the video signal of a previous frame based on the control signal. If it is not necessary, the determining unit commands light sources to be turned on. If it is necessary, the determining unit commands the light sources to be turned on when the video signal of the current frame and the video signal of the previous frame are different, and to be turned off when the video signal of the current frame and the video signal of the previous frame are identical. Through the above mentioned mechanism, power consumption of the LCD is greatly reduced.
