Organic light emitting diode display device including segmented power lines

A display device, comprising:

• a display panel including:
• a plurality of pixel circuits disposed on an active area of the display panel for emitting light,
• at least two lines including a first line and a second line disposed on the active area, the first line coupled to a first group of pixel circuits of the plurality of pixel circuits, the second line coupled to a second group of pixel circuits of the plurality of pixel circuits, and
• a first switching circuit, the first switching circuit coupled to the first line, and configured to:
• (i) in a first state, supply power at a first power level to the first group of pixel circuits coupled to the first line, and
• (ii) in a second state, supply power at a second power level to the first group of pixel circuits coupled to the first line;
• and
• a second switching circuit, the second switching circuit coupled to the second line, and configured to:
• (i) in the first state, supply power at the first power level to the second group of pixel circuits coupled to the second line, and
• (ii) in the second state, supply power at the second power level to the second group of pixel circuits coupled to the second line;
• and
• wherein a pixel circuit of the plurality of pixel circuits is configured to receive at least a first pulse along a data line to program a value for the pixel circuit, and a second pulse corresponding to an emission control signal to enable the pixel circuit to emit light based upon the programmed value, wherein the first and second pulses are received during a time period when the corresponding switching circuit is operating in the first state.
