Abstract
A tone display method is provided that can prevent image quality deterioration of the dynamic image and can avoid a cost increase. When an image with 256 tones is displayed, one field is divided into 37 subfields for one color. Among the 8 bits corresponding to the 256 tones, the six high-order bits from the third bit are displayed by means of time width modulation using 35 subfields SF3-SF37 having weights of ''4' and '8'. The two low-order bits are displayed on a binary base using two subfields SF1 and SF2 whose weights are ''1' and '2', respectively.
