Guangdong LED major scientific research achievements are about to enter the stage of industrialization

Recently, the LED industry released major LED research results at the Guangdong Science Center. Including "high-efficiency intelligent LCD TV development and industrialization based on the overall ultra-thin liquid crystal display backlight module technology", "LED epitaxial raw materials high-purity metal organic compounds (MO source)", "AC LED white light and phosphor technology", "go A number of projects such as the development of power-based high-voltage LED core technology and "high-power high-brightness and high-reliability flip-chip LED chip-level packaging technology" are in mass production or are about to enter the industrialization stage.

Among them, Zhongke Hongwei Company and Zhaoxin Group have successively developed domestic MOCVD prototypes, which broke through the bottleneck of major equipment subject to human beings; a new high-efficiency high-power LED chip based on zinc oxide epitaxial transparent electrode structure, and a batch of GaN homoepitaxial technology. Independent intellectual property rights technology fills the gap in Guangdong's industry, and a number of LED major scientific and technological achievements have entered the stage of industrialization;

“Development and industrialization of high-efficiency intelligent LCD TV based on overall ultra-thin liquid crystal display backlight module technology”, embedded enhanced dynamic backlight control technology, energy saving 30-50%, integrated design, saving 15% compared with traditional process;

"LED epitaxial raw material high-purity metal organic compound (MO source)" project, using rectification to purify trimethyl gallium, the production process is simple, safe, energy-saving and environmentally friendly, not only improve production stability, but also greatly improve production efficiency;

"AC LED white light and phosphor technology" uniquely proposed a technical solution combining AC LED phosphor and AC direct drive to effectively compensate for the illuminating fluctuation of AC power supply to LED and solve the stroboscopic problem of AC LED;

"Development and industrialization project of power supply high-voltage LED core technology", through the use of special high-voltage process LED driver chip, greatly reduce the cost and heat loss of the power supply part, extend the service life and simplify the production process;

"High-power, high-brightness and high-reliability flip-chip LED chip-level packaging technology" is expected to develop more than 4 high-power, high-brightness and high-reliability flip-chip LED chip-level light source products, and the light source mass production level reaches 140 lumens per watt or more. Achieve 40 million high-power LED chips per year.
