摘要：
A driver for a matrix display successively stores digital data codes. During a first time interval, the driver charges a capacitor coupled to its output to a voltage level represented by the most-significant bits of a stored data code. During a second time interval, the driver shifts the voltage on the capacitor by a magnitude represented by the least significant bits of the stored data code.
