摘要： A display driving method drives a display to make a gradation display on a screen of the display depending on a length of a light emission time in each of subfields forming 1 field, where 1 field is a time in which an image is displayed, N sub fields SF1 throuh SFN form 1 field, and each sub field includes an address display-time in which a wall charge is formed with respect to all pixels which are to emit light within the sub field and a sustain time which is equal to the light emission time and determines a luminance level. The display driving method includes the steps of setting the sustain times of each of the sub fields approximately constant within 1 field, and displaying image data on the display using N+1 gradation levels from a luminance level 0 to a luminance level N.

摘要： An image processing device has an error distribution unit, and a multiplier. The error distribution unit carries out an error distribution operation to artificially increase the number of shades to be displayed on a display. The multiplier multiplies an input signal by a multiplication coefficient, so that the input signal is separated into display data and error data along a bit boundary and the error distribution operation is carried out on the input signal. Further, a semiconductor integrated circuit has a dither pattern generator, an adder, and an error distribution unit. The dither pattern generator stores a plurality of dither patterns in advance and receives an input image signal, the adder receives the input image signal and a pattern signal from the dither pattern generator, and the error distribution unit carries out an error distribution operation on the output of the adder. Therefore, the image processing device can realize a smooth display characteristic for the entire range of input shades.
