  • Patent number: 10103215
    Abstract: The present disclosure provides a display panel and a display device including the display panel. The display panel includes a display area and a peripheral area outside the display area. The display area is provided with OLEDs, first and second power lines. The peripheral area is provided with at least one driving chip. OLEDs are distributed in a matrix. First power lines extend in a first direction, second power lines extend in a second direction, and first power lines are intersected and connected with second power lines to form a grid structure electrically connected with anodes of OLEDs. The driving chip is electrically connected with the grid structure. The grid structure includes grids defined by first power lines being intersected with second power lines, and has a larger grid density at one position than that at another position closer to the driving chip.

  • Patent number: 10032412
    Abstract: An organic light emitting diode pixel driving circuit includes a pixel capacitor for storing a received voltage and coupling a change valve of the voltage at a first electrode thereof to a second electrode thereof; a first transistor for providing a reference voltage to the first electrode of the pixel capacitor under the control of a first light emitting signal; a third transistor for transmitting a data voltage to second electrode of the pixel capacitor under the control of the first scanning signal; and a fourth transistor; thereby overcoming the uneven display of the entire image, which is caused by the drift of the threshold voltage of the driving transistor and the different driving current driving the different OLEDs to emit light when the different OLEDs receive the same image data signal, the different driving current is caused by the difference the high-level power supply voltages.
