(54) Display drive circuit and drive method for the same


(57) A display drive circuit and a drive method for the same are proposed. The drive circuit is alternately controlled by a first control signal and a second control signal in each frame time, and alternately performs storage or release of image data to a first maintaining capacitor and a second maintaining capacitor in an LCD panel according to scan signals. Frames stored in the first maintaining capacitor and the second maintaining capacitor in the LCD panel can therefore be continuously and alternately output for display.
