Abstract

The invention relates to the technical field of display, in particular to a display panel, a driving method of the display panel and a display device. The display panel comprises a pixel circuit and a driving circuit, the pixel circuit comprises at least one light-emitting element, and the light-emitting element comprises a multi-layer quantum well structure; the driving circuit is used for adjusting the driving current input into the light-emitting element, so that the light-emitting element emits light in corresponding colors according to the driving current. The display panel can control the light-emitting element to display different colors and display brightness through a simple pixel circuit, and the display performance of the display panel and the display device is improved.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. 【Background technique】 [0002] Full-color LED displays are favored by the market for their rich colors, high saturation, and high definition. However, the existing full-color LED display often adopts the integration of multiple single-color LEDs, or uses short-wavelength LEDs plus fluorescence through secondary light emission. These technical solutions to realize LED full-color display, the structure and technological process of the full-color display LED produced are complicated, and the high PPI (Pixels Per Inch, pixels per inch) of LED full-color display is limited, which cannot realize the market's high demand for display panels. PPI display requirements. [0003] Therefore, how to reduce the structural and process complexity of full-color LED display and realize high PPI display is a technical pro...
