ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE

摘要

An organic electroluminescence display device is provided in which circuit components can be installed at a high density and which can reduce power consumption. The organic electroluminescence display device of the present invention comprises a display part including a first display area including a plurality of first pixels and a second display area including a plurality of second pixels, and a switch unit formed from a plurality of transistors and switching between display in the first display area and display in the second display area. The switch unit does not drive the plurality of second pixels during a frame time period for driving the plurality of first pixels in the display part and drives the plurality of second pixels during a vertical retrace time period in which the plurality of first pixels are not driven in the display part.
