Abstract:
An active-matrix LCD (AM-LCD) device comprising a pixel array including a plurality of pixels arranged in a matrix, each of said pixels having a pixel transistor, a pixel electrode connected to a source of said pixel transistor and a common electrode, a plurality of data lines each connected to a drain of each pixel transistor arranged in a column of said pixel array, a plurality of gate lines each connected to a gate of each pixel transistor arranged in a row of said pixel array, a data driver block for driving said data lines, a gate driver block for driving said gate lines, a switching section for switching power source for said pixel array, a control section for controlling said data driver block, said gate driver block and said switching section to drive said pixel array in a reversible driving scheme, wherein said control section controls a mode switching so that a potential difference between said pixel electrode and said common electrode in each pixel has a uniform polarity among said pixels during a switching period after image data for said data line is switched off and before the power source for said pixel array is switched on for said mode switching.
