Abstract
A display element drive unit is provided with a power-on time display section which separately presets grayscale display digital data to output a grayscale display level voltage different from a grayscale display level voltage based on incoming display data signal to the display elements during a given period between power-on of the display panel and output of the grayscale display level voltage based on the incoming display data signal. With this arrangement, the present invention provides a display element drive unit capable of easing an instantaneous display of distorted image that occurs in a given period at power-on of the panel while minimizing increase of a circuit scale; a display device including the display element drive unit; and a display element drive method.
