Abstract
A liquid crystal display and a dummy-loading device thereof are provided. The dummy-loading device is suitable for a liquid crystal display having a plurality of pixel bands. The liquid crystal display comprises an input signal line to receive image data, and a plurality of horizontal switches and a plurality of shift registers connected in series. The shift registers sequentially shift and output a video control signal for conducting the input signal lines and the pixel bands. A dummy-loading device is disposed in the liquid crystal display, comprising a dummy pixel band, a dummy shift register and a dummy horizontal switch on one side of the liquid crystal display, for providing the edge band compensation to resolve unbalanced imaging.
