摘要： A display array driving circuit is provided. The circuit includes a first memory block, a second memory block, and a main circuit. The first memory block stores the most significant bit (MSB) of the data of one pixel. The second memory block is utilized to store non-MSB bits of the data of the pixel. The main circuit retrieves the MSB of the data of the pixel from the first memory block when the display array is in a predetermined mode, for displaying the pixel data on the display array. In the predetermined mode, the main circuit does not retrieve the non-MSB bits of the data of the pixel, and power consumption is subsequently reduced.

摘要： A power-on screen pattern correcting apparatus is for correcting start output data of output terminals of a source driver such that a power-on screen pattern of a display is substantially uniform. The correcting apparatus comprises a flip-flop, a first logic unit and a second logic unit. The flip-flop controls a level of an inner signal to be substantially equal to a low signal level in response to a low level of a power start signal. The first logic unit enables a first signal in response to the low level of the inner signal or a low level of a high-impedance control signal. The second logic unit enables a second signal such that the output terminals are coupled to a charge sharing line and the power-on screen pattern is uniform in response to the low level of the inner signal or a low level of a charge-sharing control signal.
