Display panel and display device thereof

1. A display panel, comprising

a substrate, comprising a plurality of display areas and a plurality of non-display areas surrounding the display areas, wherein each of the display areas is divided into at least two sub-display areas along a predetermined direction; a boundary between the sub-display areas is a straight line or a polyline; and a plurality of organic light emitting diodes is disposed in the sub-display areas;

a plurality of powerlines, disposed on the periphery of each of the sub-display areas, wherein the powerlines are located in the non-display areas; the powerlines on the periphery of display areas are independent from each other and a power voltage is applied on the organic light emitting diodes of each of the sub-display areas via the powerlines so that each of the organic light emitting diodes receives the same power voltage;

wherein the display area is divided into three sub-display areas comprising a first sub-display area, a second display area, and a third display area; the boundary between the first sub-display area and the second sub-display area is a straight line or a polyline; the boundary between the second sub-display area and the third sub-display area is a straight line or a polyline; the boundary of the first sub-display area and the third sub-display area is a straight line or a polyline; and the plurality of organic light emitting diodes are located on the first sub-display area, the second sub-display area, and the third sub-display area;

wherein a chip is disposed on the non-display area of the first sub-display area, a plurality of first powerlines are disposed on the non-display areas next to the right side and the left side of the first sub-display area respectively, and the first powerlines are connected with a first power source of the chip, used for receiving the first power voltage applied to all of the organic light emitting diodes in the first sub-display area;

wherein a plurality of second powerlines are disposed on the non-display areas next to the right side and the left side of the first sub-display area respectively; the second powerlines are connected with a second power source of the chip, used for receiving the second power voltage applied to all of the organic light emitting diodes in the second sub-display area; and

wherein a plurality of third powerlines are disposed on the non-display areas next to the right side and the left side of a third sub-display area respectively; the first powerlines, the second powerlines and the third powerlines are independent from each other and the third powerlines are connected with a third power source of a chip, used for receiving a second power voltage applied to all of the organic light emitting diodes in the third sub-display area, the first powerlines are connected to an anode of all the organic light emitting diode in the first sub-display area, the second powerlines are connected to an anode of all the organic light emitting diode in the second sub-display area, and the third powerlines are connected to an anode of all the organic light emitting diode in the third sub-display area.

2. The display panel according to claim 1 , wherein the polyline is selected from one of the following group of the rectangular zigzag line, the trapezoid zigzag line and the triangular zigzag line.

3. The display panel according to claim 1 , wherein the first power voltage, the second power voltage and the third power voltage are negative voltage.
