Abstract: PROBLEM TO BE SOLVED: To enhance the image quality of a liquid crystal display device with a built-in D/A (Digital-to-Analog) converter. SOLUTION: Digital image data of n-bit is converted to n+m-bit by a γ compensation table and is displayed by using the D/A converter of n+m-bit. A logic section of a peripheral driver is driven by a low-voltage common power source to undergo noise preventing measures. The data of the D/A converter is not inverted and the power source of the D/A converter is made into alternating current. Also, a circuit for compensating the delay time in the driver is provided.
