DISPLAY DEVICE, IMAGING DEVICE AND GRAY LEVEL VOLTAGE GENERATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To perform gamma correction that permits high speed switching among a variety of gamma correction curves while at the same time keeping the increase in circuit area and power consumption to a minimum.SOLUTION: The display device includes: a voltage division circuit adapted to generate a plurality of voltages using a resistance division circuit; a gray level voltage generation unit adapted to generate a gray level voltage using the voltages generated at division points of the resistance division circuit; an amplification circuit adapted to amplify a given voltage and supply the amplified voltage to at least one of the division points of the resistance division circuit; and an adjustment unit adapted to adjust an amplification factor of the amplification circuit.
