Problems solved by technology

[0003] In the Micro-LED display panel in the related art, because Micro-LEDs of different colors have different luminous efficiencies, the Micro-LEDs with low luminous efficiency need to heat for a long time to achieve the set display effect, so that the Micro-LEDs with low luminous efficiency The service life of the display panel is reduced, so it is difficult to achieve both the service life of the display panel and the luminous effect

Abstract

The invention discloses a display panel and a display device.The display panel comprises a plurality of pixel areas, each pixel area at least comprises a three-primary-color light-emitting unit, the display panel comprises an array substrate and a light-emitting device layer, the light-emitting device layer comprises at least one combined LED wafer distributed in the preset pixel area, each combined LED wafer comprises at least two light-emitting units, and the light-emitting units are arranged in the array substrate. At least one of the at least two light-emitting units is a red light-emitting unit, and the number of the green light-emitting units and the number of the blue light-emitting units in the preset pixel area are both smaller than the number of the red light-emitting units; wherein in one frame of time, the duty ratio of the light emitting stage of the red light emitting unit is less than 100%; in one frame time, the light emitting time periods of the different red light emitting units in the same preset pixel area are at least partially not overlapped, and the sum of the light emitting stage duty ratios of the multiple red light emitting units is larger than or equal to 100%. According to the display panel provided by the invention, the display effect and the service life can be realized at the same time.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background technique [0002] Micro-LED (miniature light-emitting diode) display technology has gradually become the mainstream product of the next-generation display due to its low power consumption, long life and high brightness. Like traditional light sources, Micro-LED will also generate heat during operation. Whether the Micro-LED works stably and its quality is very important is the temperature of the Micro-LED itself. If the temperature of the Micro-LED is high, its lifespan will also be reduced. Affected. [0003] In the Micro-LED display panel in the related art, due to the different luminous efficiencies of Micro-LEDs of different colors, the Micro-LEDs with low luminous efficiency need to generate heat for a long time to achieve the set display effect, thus making the Micro-LEDs with low luminous efficiency...
