Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate and multiple pixel units located on the substrate, each pixel unit comprises a driving circuit anda light-emitting element, and each driving circuit is located between the substrate and the corresponding light-emitting element and used for driving the corresponding light-emitting element to emitlight; one or more light-emitting elements are micro LEDs; for the pixel units with the light-emitting elements as the micro LEDs, each driving circuit at least comprises a first thin film transistor,a source electrode and a drain electrode of each first thin film transistor are located on a corresponding source and drain electrode layer, and a first electrode of each micro LED is electrically connected with the source electrode or the drain electrode of the corresponding first thin film transistor; each pixel unit with the light-emitting element as the micro LED further comprises a metal structure, each metal structure is located between the substrate and the corresponding source and drain electrode layer, and the source electrode or the drain electrode of each first thin film transistorelectrically connected with the first electrode of the corresponding micro LED is electrically connected with the corresponding metal structure. According to the technical scheme, the temperature ofthe micro LEDs is effectively lowered, and the problem is solved that the light-emitting efficiency of the micro LEDs is lowered.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, micro LED (Micro Light Emitting Diode, micro light-emitting diode) has been gradually applied to the display field due to its small size, high luminous efficiency and low energy consumption. To install optical and electronic components such as the front camera, it is necessary to set a hollowed-out area in the middle of the upper end of the display screen of the mobile phone, and to install optical and electronic components in the hollowed-out area, resulting in the reduction of the display area of ​​the display panel. The size of the LED is much smaller than the size of the organic light-emitting element. In the area where the optical and electronic elements are installed in the display panel, micro LEDs are used to achieve high-t...
