Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, pixel circuits arranged on one side of the substrate, a first connecting part, a compensation part and a power line, the multiple pixel circuits are distributed in an array mode in the first direction and the second direction, and the first direction and the second direction intersect; the pixel circuit comprises a driving transistor and a storage capacitor, the driving transistor comprises a gate part, the storage capacitor comprises a first pole plate and a second pole plate, the gate part is multiplexed as the first pole plate, and the second pole plate is connected with a power line; and the first connecting part and the compensation part are both connected with the gate part, the orthographic projection of the compensation part on the substrate and the orthographic projection of the second polar plate on the substrate are overlapped, and the compensation part and the power line both extend in the second direction and are located on the same film layer. According to the embodiment of the invention, the stability of the grid potential of the driving transistor can be improved, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is one of the hot spots in the field of display research today. Compared with Liquid Crystal Display (LCD), OLED display has low energy consumption, low production cost, self-illumination, and wide viewing angle. And the advantages of fast response speed, etc. At present, OLED array substrates have begun to replace traditional LCD array substrates in display fields such as mobile phones, PDAs, and digital cameras. [0003] A pixel circuit is provided in the OLED display panel to drive the OLED light-emitting element, and the pixel circuit includes a driving transistor. However, the gate potential of the driving transistor is unstable, which affects the display effect. Contents of the invention [0004] The present application provides a display panel and a display...
