Abstract

The invention discloses an LED material for a multifunctional curved display screen and a manufacturing method thereof. The LED material is specifically composed of an LED chip and an LED packaging material, wherein the LED chip specifically uses silicon carbide as a substrate and gallium nitride as a core body, two electrodes are distributed on the surface of the device and an L-shaped electrode at the bottom, in which 2.5% silicon dioxide, 1.6% indium, 1.2% arsenic and 0.6% aluminum; LED packaging materials specifically: polymerize vinyl silicon and siloxane into vinyl silicon high polymers, polyhydrogen siloxane and vinyl hydrogen silicone resin into hydrogen-containing high polymers, and then A silicone resin synthesized from two high polymers under the action of an inhibitor and a platinum catalyst. The invention does not use sapphire as the substrate, can be applied to large curved surfaces, high toughness, anti-aging, good electrical performance, can emit light with different characteristics according to the nature of the output signal, and increase the focus degree through the curved surface display, and is used for multi-function LED display for home use.

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 (In) 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...
