Abstract

The invention relates to a display panel and a preparation method thereof. The display panel comprises a light-emitting substrate, a color conversion substrate and an attaching structure attached between the light-emitting substrate and the color conversion substrate. The attaching structure comprises an adhesive layer, liquid crystal molecules and quantum rods, wherein the liquid crystal molecules and the quantum rods are doped in the adhesive layer and are arranged in a directional mode, wherein the long axis directions of the liquid crystal molecules and the quantum rods are parallel to the light-emitting substrate. According to the display panel and the preparation method thereof, the color crosstalk of the high PPI display panel can be improved, so that the display effect of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] Micro-Light Emitting Diode (Micro-LED) display panels have broad applications in outdoor fields such as wearable devices and vehicle-mounted devices due to their advantages such as high brightness, high contrast, wide color gamut and wider viewing angle display. application. [0003] At present, based on the red Micro-LED in Micro-LED display panels, there are some problems, such as low luminous efficiency, high temperature attenuation, large driving current, and inconsistent light patterns, etc. Micro-LED display panels mostly use blue Micro-LED The light-emitting substrate is combined with the structure of Quantum Dot Color Conversion (QDCC) to avoid the limitation of red Micro-LED. However, since the light emitted by the blue Micro-LED light-emitting substrate is non-collimated light, it is easy...
