Abstract

The present invention discloses an LED material used for a multifunctional curved display screen and a manufacturing method thereof. The LED material is concretely composed of an LED chip and an LED packaging material, wherein the LED chip concretely takes the silicon carbide as a substrate and the gallium nitride as the core body, two L-shaped electrodes are distributed on the surface and at thebottom of a device, and 2.5% of silicon dioxide, 1.6% of indium, 1.2% of arsenic and 0.6% of aluminum are added in the gallium nitride core body according to the total mass of the gallium nitride. TheLED packaging material is characterized by polymerizing the vinyl silicone and the siloxane into the vinyl silicon high polymer, polymerizing the polyhydric siloxane and the vinyl hydroxy silicone resin into the hydrogen containing high polymer, and synthesizing the two high polymers into the organic silicon resin under the action of an inhibitor and a platinum catalyst. The present invention provides the LED material that does not adopt the sapphire as the substrate and can be suitable for the multifunctional household LED display screen which has a large curved surface, is anti-aging, is high in toughness and good in electrical performance, can emit the light rays of different characteristics according to the output signals of different properties and increases the focusing degree by the curved display.

Description

technical field [0001] The invention relates to the field of display materials, in particular to an LED material for a multifunctional curved display screen and a manufacturing method thereof. Background technique [0002] LED display (LED display) is a flat-panel display, which is composed of small LED module panels and is used to display various information such as text, images, videos, and video signals. [0003] LED, Light Emitting Diode (light emitting diode abbreviation). It is a diode made of a compound made of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), and indium (ln) by controlling the display mode of a semiconductor light-emitting diode. When electrons and holes Visible light can be radiated when recombined, so it can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, sili...
