Color image display apparatus.

摘要

A flat CRT type color image display apparatus comprises a number of horizontally disposed parallel line cathodes, vertical and horizontal deflection means and electron beams control means, wherein a clock pulse signal is produced by frequency-multiplying a pulse signal which is synchronized with color sub-carrier of the color TV signal, chrominance signal is A/D converted using the clock signal, therewith producing a PWM signal with which electron beams are controlled.
