Abstract
The present invention relates a time-sharing multiplexing driving method and framework for image signals. By means of a plurality of wiring paths, the turned-on orders of the signal switches of the pixel units in a liquid crystal panel (LCD) are sequentially controlled so that the pixel units of two adjacent phases in the panel can have the same turned-on order. This not only can avoid the situation where the switch control signal serial connecting path in the panel is so long that the control signal of the end switch will be seriously distorted for the excessively great load, but also make the variation amounts of the adjacent pixel data voltages the same. Therefore, the objective of the invention can be achieved. Namely, no joint space is generated during the image signal time-sharing multiplexing driving.
