US Patent 10573219 Display driver, electro-optical device, and electronic apparatus

A display driver includes a first digital-to-analog (D/A) converter circuit configured to convert upper-bit data of display data into a gradation voltage corresponding to the upper-bit data, a second digital-to-analog (D/A) converter circuit configured to output a reference voltage that is varied in accordance with lower-bit data of the display data, and an inverting amplifier circuit configured to amplify the gradation voltage with reference to the reference voltage and to drive a data line of an electro-optical panel.
