Patent attributes
There is disclosed a liquid crystal driving circuit configured to supply an analog voltage in accordance with digital grayscale data to each of a plurality of signal lines, said circuit comprising: a reference voltage generation circuit configured to output analog reference voltages corresponding to each of said digital grayscale data; a plurality of buffer amplifiers configured to individually perform buffering of said respective analog reference voltages; a grayscale mode circuit configured to determine a grayscale number of said digital grayscale data based on a grayscale mode signal supplied from the outside; and an amplifier enable circuit configured to set each of said plurality of buffer amplifiers to an enable state or a disable state based on an output signal of said grayscale mode circuit.
