In a display device, one field is divided into two groups of subfields. Light-emitting cells are selected by a selective write process in a first group of subfields and a gray scale is represented by a combination of weights of subfields. Light-emitting cells are selected by the selective write process in a first subfield (SF11) of a second group of subfields, and non-light-emitting cells are selected from the light-emitting cells by a selective erase process in the remaining subfields (SF12,SF13,SF1L) of the second group of subfields. In the second group of subfields, a gray scale is represented by the sum of weights of subfields from when the light-emitting cell is selected in the first subfield to when the non-light-emitting cell is selected. In this manner, a gray scale of one field may be represented by a combination of the first and second groups of subfields. |
