Abstract
In a self-luminous display panel driving system, one field of a composite video signal is divided into N sub-fields, luminance of each pixel is set by a pixel data. The pixel data comprises N bits corresponding to the number of the sub-field. A present pixel data of a pixel is compared with a prior pixel data of a same pixel and a change between a data of a highest luminance and a data of a luminance of a one digit lower is detected. An inter-frame change signal is produced when a change is detected. In response to the inter-frame change signal, the present pixel data is corrected so as to change the sub-field of the present pixel data.
