Abstract

The present invention belongs to the field of display devices, and provides a display device and a preparation method thereof. The display device comprises a substrate, a light-emitting device, a first package layer and a second package layer, the first package layer comprises a carbon material layer and first metal nanoparticles/second metal nanowire layer. The carbon material layer is high in light transmission and good in thermal conductivity can effectively absorb the heat emitted by the device; the first metal nanoparticles and the second metal nanowire layer have good electrical conductivity, the first metal nanoparticles are diffused and attach to the surface of the second metal nanowire to allow the surface of the second metal nanowire layer to be rough to block the light refraction so that the first metal nanoparticles and the second metal nanowire layer have high light transmission and heat stability and can ensue the continuous stability of the first package layer light transmission thermal conductivity; through combination of the advantages of the two, the first package layer can ensure the continuous stability of the light transmission thermal conductivity of the device while timely emit the heat emitted by the device so as to improve the device life.

Description

technical field [0001] The invention belongs to the field of display devices, in particular to a display device and a preparation method thereof. Background technique [0002] Quantum dots (Quantum dots, QDs) have the characteristics of tunable luminescence, narrow luminescence line width, high photoluminescence efficiency and thermal stability, so the quantum dot light-emitting diode (QLED) with quantum dots as the light-emitting layer is very Potential next-generation display and solid-state lighting sources. [0003] Quantum dot light-emitting diodes have received extensive attention and research in the fields of lighting and display in recent years due to their advantages such as high brightness, low power consumption, wide color gamut, and easy processing. However, due to the poor waterproof and oxygen performance of the existing QLED devices, water and oxygen in the air can easily penetrate into the QLED devices and affect the performance of the devices. Therefore, t...
