Title: Image display apparatus
Inventor: KAWAHARA ISAO
IPC: G09G3/296
Filed: 2002-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an image display apparatus in which the occurrence of a moving image false edge can be suppressed rather than a conventional apparatus. SOLUTION: The initialization corresponding to erasure is performed just five times from R1 to R5. Namely, in the subfield group of subfields SF1-SF15, the initialization period R1 is provided just before the address period of the subfield SF1, and no initialization period is provided before the address periods of the subfields SF2-SF15. Because of such an encoding and driving method, the emission of light is started in the position of the top subfield according as the value of an input signal increases and further, such encoding that the subfield to emit light is drawn forwards as the value of the input signal increases is performed. Thus, since correlation between the size of the input signal and a light emitting pattern is guaranteed, the peculiar moving image false edge in so-called moving image display can be eliminated.
