Abstract:
1. A display device which displays images corresponding to an input image signal in accordance with a sub-field method, comprising: (a) a first block which receives an image signal, varies the number of bits of the received image signal, and outputs the resulting image signal; (b) a second block which calculates an average picture level (APL) of an image defined by said image signal transmitted from said first block; (c) a third block which receives said image signal from said second block, converts the received image signal into sub-field coding data, and outputs said sub-field coding data to a display panel; and (d) a fourth block which receives said average picture level from said second block, converts the received average picture level to the number of sustaining pulses, transmits a sustaining pulse output signal representing said number of sustaining pulses to said display panel, and transmits said number of sustaining pulses to said third block, wherein said third block selects a number of bits of a signal to be input thereto, in accordance with said number of sustaining pulses received from said fourth block.
