Jiwei.com reported that on April 15, Shenzhen Konka said in an institutional survey that the company is actively promoting the industrialization of its semiconductor business. At present, the company has built a full-process R&D and production line for Micro LED. The self-developed hybrid mass transfer technology has greatly improved the transfer efficiency and yield, and has successfully transferred a large number of wearable displays; the Micro LED chip developed by the company has been completed. Trial production of small and medium batches.
In September 2019, Konka Group invested 1.5 billion yuan to jointly establish Chongqing Konka Semiconductor Optoelectronics Research Institute with Chongqing Liangshan Industrial Investment Co., Ltd. Micro LED related product development, production and sales.
In October of that year, Konka released the Smart Wall future screen using Micro LED technology. The product adopts ultra-high-precision mass transfer technology to realize the transfer and bonding of nearly 100 million micron-level Micro LED chips, and point-to-point driving to achieve precise control of each pixel, and the dot pitch between LEDs can be reduced to P0 .68mm.
In 2021, Shenzhen Konka will make breakthroughs in chip miniaturization, mass transfer and other technical aspects, independently design and produce 15*30 micron-level Micro LED display chips, and the transfer yield rate of the self-developed “hybrid mass transfer technology” will reach 99.9 %, providing a solid foundation for industrial entry and rapid development for further expansion of application markets such as wearable display, vehicle display, and immersive display.
