Abstract: A apparatus and method for driving a liquid crystal display that minimizes the generation of electromagnetic interference (EMI) in a cost effective manner includes a gate control signal generator that generates a gate control signal using a externally inputted synchronizing signal, a data control signal generator that generates a data control signal using the synchronizing signal, a data aligner that re-aligns externally inputted video data, a plurality of buffers at output terminals of the gate control signal generator, the data control signal generator and the data aligner, and a control unit that applies control signals to the buffers to control current values of signals outputted by the buffers.
Abstract: A method for automatically adjusting pictures on a display device, by which a plurality of reference points and the corresponding slope values are stored in a memory of the display device. The reference points and the corresponding slope values, as well as the synchronous frequency and the image timing, set by a user are used by a microprocessor within the display to determine whether to adjust the picture frame and the display position of the pictures, so as to fit the preset display values by the user.
