Chinese display panel and home appliance makers are upping the ante in next-generation solid-state display technologies, which have huge application potential in large commercial displays, mounted devices on-vehicle as well as virtual and augmented reality, industry experts said.

TV maker Konka Group Co Ltd has announced that its optoelectronic semiconductor industrial park in Chongqing has officially started operations, with several micro light-emitting diodes and mini LED assembly lines beginning production.

Li Hongtao, president of the Chongqing Konka Optoelectronics Technology Research Institute, said the company will promote scientific and technological innovation, strengthen cooperation with enterprises in the upstream and downstream segments of industrial chains, and create an ecosystem. of the next generation display industry spanning R&D, manufacturing and application. .

The Shenzhen, Guangdong province-based company has invested heavily in the solid-state display sector – one of the country’s strategic emerging industries – and increased its R&D investment in micro LED display technologies and mini LEDs.

The operation of the new semiconductor optoelectronic industrial park is conducive to ensuring the security and stability of the industrial and supply chain, achieving self-reliance in science and technology, and gaining a competitive advantage in the global industry. next-generation solid-state displays, experts said.

In 2019, Konka announced plans to invest 1.5 billion yuan ($207.6 million) to establish a micro-LED research institute with Chongqing Liangshan Industrial Investment Co Ltd for R&D, production and the sale of micro-LEDs.

The company and Chongqing Bishan District Investment Platform jointly established Chongqing Kangxin Semiconductor Industry Equity Investment Fund in 2020 to invest in new semiconductor materials, equipment, chips , IC designs, packaging and testing.

Compared with liquid crystal display and organic light-emitting diode technology, micro LED display technology has super fast response time, high brightness, wide viewing angles and longer service life. Mini LEDs are considered millimeter LEDs, while micro LEDs are micrometer LEDs.

According to a report by LEDinside, a research institute of technology research firm TrendForce, the global market value of micro-LEDs and mini-LEDs is expected to reach $1.38 billion by the end of this year.

Sun Jian, senior analyst in the TV department of market research firm Sigmaintell Consulting, said, “Major panel and appliance manufacturers have entered the mini LED space to improve their competitiveness in the LED segment. high-end televisions and improve their profitability in a context of increasing pressure. oversupply in the field of panels.”

Sun said global shipments of mini LED TVs are expected to reach 3.7 million units this year, a year-on-year increase of 135 percent, and that figure will rise to 9 million units in 2025.

Micro-LEDs have many applications in large commercial displays, but they still take longer to reach mass production, Sun added.

Roger Chu, research director at LEDinside, said micro-LEDs have a lot of potential and could find many applications, including virtual reality devices, augmented reality projections, optical sensors and fingerprint recognition. .

Since this year, the transaction volume of next-generation display products, including mini LEDs, lasers, OLED and 8K TVs, has seen robust growth, said Jie Meijuan, general manager of electronics department. general public at All View Cloud, a consulting firm based in Beijing. specializing in the home appliance sector.

TV manufacturers are attaching greater importance to product added value and leveraging innovative display technologies to launch high-end products, Jie said, adding that technological innovation has become an important force to enhance the high-end and more intelligent development of the television industry.
