Abstract:
1. A light emitting display device comprising: a substrate comprising a display area and a peripheral area external to the display area; a plurality of data lines in the display area for transmitting data signals for displaying images; a plurality of pixel circuits in the display area and coupled to the data lines; a plurality of pixel power lines in a first direction in the display area, for supplying a power supply voltage to the pixel circuits; a plurality of first signal lines in the peripheral area; a data driver coupled to the first signal lines for time-dividing first signals corresponding to the data signals and for transmitting time-divided first signals to the first signal lines; a demultiplex unit, including a plurality of demultiplexers in the peripheral area for respectively receiving the time-divided first signals from the first signal lines; a first power cable in a second direction crossing the first direction in the peripheral area and coupled to first terminals of the pixel power lines; and a second power cable in the second direction in the peripheral area and coupled to second terminals of the pixel power lines, wherein each demultiplexer receives a time-divided first signal from the first signal line and transmits the data signals to at least two data lines.
