Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel of the present invention includes: a substrate, an active switch, formed on the substrate; a color resistance layer, formed on the active switch; a first electrode layer, formed on the color resistance layer; a light emitting diode, formed on the first electrode layer the second electrode layer, formed on the light-emitting diode; the encapsulation layer, formed on the second electrode layer; the driving circuit, electrically connected to the first electrode layer and the second electrode layer; the light-emitting diode includes a red light-emitting layer, a green A light-emitting layer and a blue light-emitting layer, the blue light-emitting layer includes germanium-silicon quantum dot materials; the proportion of silicon in the red light-emitting layer is 10%-35%, and the proportion of germanium is 65%-90% The proportion range of silicon element in the green light-emitting layer is 45%-65%, the proportion range of germanium element is 35%-50%; the proportion range of silicon element in the blue light-emitting layer is 65%-95%, The proportion range of germanium element is 5%‑35%. The invention can improve the recombination performance of the light emitting diode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Existing displays are generally controlled based on active switches, which have many advantages such as thin body, power saving, and no radiation, and have been widely used, mainly including liquid crystal displays, OLED (Organic Light-Emitting Diode) displays, QLED (Quantum Dot Light Emitting Diodes) displays, plasma displays, etc. From the perspective of appearance and structure, there are both flat-panel displays and curved-surface displays. [0003] For liquid crystal displays, including two parts of the liquid crystal panel and the backlight module (Backlight Module), the working principle of the liquid crystal display is to place liquid crystal molecules in two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the liquid crystal. The direction of r...
