Abstract:
1. A drive method for an EL display panel that has a display screen in which pixels are formed in a matrix state, the EL display panel comprising: EL elements arranged in a matrix; driver transistors which supply current to be passed through the EL elements; a first condenser having a first terminal and a second terminal; first switching elements placed in current paths of the EL elements; a switching transistor which is connected between a gate terminal and another terminal of said driver transistor; and a gate driver circuit which turns on and off the first switching elements for control; wherein: said first terminal of the condenser is connected to said gate terminal of the driver transistor, said second terminal of the first condenser is connected to an electrode to which a predetermined voltage is impressed, said switching transistor has a multi-gate structure, the gate driver circuit generates a plurality of stripe non-display areas on said display screen of the EL display panel by controlling the first switching elements in an off-state two or more times during one frame period, the gate driver circuit moves the plurality of stripe non-display areas in a scanning direction of the gate driver circuit at a cycle of one frame period, and an operation for retaining an image signal applied to each pixel is executed only once during the one frame period.
