Abstract
A display driving device according to the present disclosure capable of changing image data at a different time for each color when the image data is changed includes: a first array composed of sampling latches configured to latch n-bit image data for each channel; a second array composed of holding latches configured to latch the image data latched in the sampling latches at a latch timing determined for each latch group; a signal generation circuit configured to generate a latch enable signal which causes the holding latches to perform a latch operation at the latch timing determined for each latch group; and a third array including level shifters configured to shift a voltage level of the image data output from the holding latches.
