Abstract:
A drive unit of an active matrix type light-emitting display panel having a plurality of light-emitting elements which are disposed at a plurality of intersecting positions where a plurality of data electrode lines and a plurality of scan electrode lines intersect and the light emission of which light-emitting display panel is controlled by drive circuits, respectively, comprising:a data driver for supplying image data to the respective data electrode lines, a scan driver for sequentially supplying a scan signal to the respective scan electrode lines, and control means for stopping the operation of the data driver when a partial display drive for controlling the light emission of a part of the effective light-emitting elements in the display panel is executed and when the scan driver scans a non-display region; wherein said drive circuits include control transistors for transmitting image data supplied from the driver based on a scan signal supplied from the scan driver and drive transistors for supplying a drive current to the light-emitting elements based on the image data transmitted by the control transistors, at least one of said control transistors and at least one of said drive transistors being correspondent to each light-emitting element.
