ABSTRACT:
An n-bit digital image data is converted to (n+m)-bit data with a g-correction table, and displayed by the use of a (n+m)-bit D/A converter. A peripheral-driver logic section is driven with a low-voltage common power source and countermeasures to noise are taken. Data input to the D/A converter is not reversed and the power to the D/A converter is made alternating to apply an AC voltage to aligned crystal layer. A circuit is provided in order to compensate for a delay time in the driver. With this configuration, the image quality of a liquid crystal display apparatus in which the D/A converter is built is improved.
