Abstract

The invention provides a display panel and a display device. The display panel comprises a first pixel and a first reference line which are connected, and a second pixel and a second reference line which are connected, wherein the first pixel comprises a first light emitting diode and a pixel driving circuit, the second pixel comprises a second light emitting diode and a pixel driving circuit, andthe pixel driving circuit comprises a driving transistor and a compensation transistor; in the pixel driving circuit, a compensation transistor is used for detecting a threshold voltage of a drivingtransistor; in the first pixel, the pixel driving circuit is used for controlling the potential of the first reference line to be transmitted to the first electrode A of the first light emitting diode; in the second pixel, the pixel driving circuit is used for controlling the potential of the second reference line to be transmitted to the second A electrode of the second light emitting diode; theturn-on voltage of the first light emitting diode is smaller than that of the second light emitting diode, and the potential of the first reference line is smaller than that of the second reference line. According to the invention, the brightness of the display panel is uniform.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of display technology, in particular to a display panel and a display device. [0003] 【Background technique】 [0004] In the prior art, organic light emitting display panels are widely used in smartphones or similar devices; however, red organic light emitting diodes, green organic light emitting diodes, and blue organic light emitting diodes in organic light emitting display panels are different, and in organic light emitting display panels The unreasonable signal lines lead to uneven brightness of the organic light-emitting display panel.
