Claims (1)

[Scope of utility model registration request] Provided in a display device using a color matrix panel in which the arrangement order of three primary color display elements arranged sequentially with the horizontal direction as the row direction is changed for each row, the primary color signals applied to each of the display elements are sequentially switched and derived. a presettable ternary first counter for counting drive clocks in the row direction of the panel; and a second counter for counting horizontal synchronizing pulses and presetting the count value in the first counter. and switching means for serially deriving one of the three primary color signals input in parallel in accordance with the output of the first counter.
