Title: Display apparatus with color video control signal function

Abstract: A display apparatus for converting the analog video signals from a host into corresponding digital video data applied to an LCD panel, comprises a microprocessor for generating a video level control signal to control the level of the video data, a preamplifier for amplifying the analog video signals according to a given amplification factor control signal, an A/D converter for converting the amplified analog video signals of the preamplifier into corresponding digital video data based on the read clock signal from an input PLL, and an LCD driver for setting the value of the input video data based on the video level control signal to deliver the digital video data from the A/D converter to the LCD panel, wherein the LCD driver generates an amplification factor control signal applied to the preamplifier to reduce the value of the digital video data from the A/D converter when the value of the digital video data is greater than the set value of the input video data.
