<P>PROBLEM TO BE SOLVED: To solve a problem of occurrence of pseudo contour in a display device in which one frame is divided into a plurality of subframes and a gray scale is expressed by a time gray scale method. <P>SOLUTION: The gray scale is expressed by sequentially adding a weight of each subframe (light emission period, the number of light emission times, and the like). Further, an erasing diode is provided in a pixel. By turning this erasing diode on, the signal stored in the pixel is erased, thereby a non-light emission period is provided. Accordingly, subframes with different light emission periods can be easily formed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
