DITHERING SYSTEM FOR EXPRESSION OF GRAY SCALE IN PLASMA DISPLAY PANEL

摘要

to the invention the inverse gamma corrected signal according to the dithering system for the gradation expression in the plasma display decimal fraction part and integer divided by the separation unit ; Error diffusion unit that performs a dithering by using the error diffusion separated decimal ; Mask dithering unit for dithering the error diffusion to the input signal ; A first multiplexer for selecting as input to a carry signal outputted from the dither mask portion and the signal output from the error diffusion unit ; Decimal coupler and the error diffusion unit that combines the output signal and the integer portion separated in the separation section of the first multiplexer small number , a carry- select unit for controlling the dither mask portion and the first multiplexer .
