FIELD: control of liquid-crystalline color displays. ^ SUBSTANCE: in accordance to the invention, video signal of same size may be derived with lesser number of clock impulses. Device and method realize a block for controlling clock impulses, which provides clock impulses for operation of each module, interface block which receives 16-bit data for each clock impulse in accordance with control signal of block for controlling clock impulses, a pair of 18-bit RGB buffers, which preserve data transferred through interface block, graphic buffer, which preserves graphic data from a pair of RGB buffers, switch block, which preserves data signals from a pair of RGB buffers, in graphic buffer, and digital-analog converter which transforms digital R/G/B data, preserved in graphic buffer, to analog signal for output. ^ EFFECT: increased efficiency of data transmission due to reduced processing time of central processor unit. ^ 2 cl, 9 dwg
