Display panel and display device thereof

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.
