Jan 2, 2018: Korean LED manufacturer Lumens has started producing small- and large-sized micro-LED display prototypes, which it plans to showcase at CES 2018.
The company states that it has been granted technologies that facilitates mass production of micro-LED. It has also setup micro-LED product lines, and has started producing samples. It would target the global market of automotive head-up display (HUD) and digital signage display. It is a transparent display that present information in front of drivers so that they can be aware of both road conditions and status of their vehicles.
Jung Tae-hong, President of Lumens, told Korea Herald that by the end of 2017 the company would launch the world’s first high-definition, automotive head-up display using micro-LED technology.
Lumen would partner with the Korea Institute of Machinery and Materials (KIMM), which invented the roll-to-plate transfer technology for micro-LED production.
Lumens plans to manufacture two types of micro LED products—a 0.57-inch mini display and a large, over 100-inch, digital signage display. Both these will integrate micro-LEDs. The 0.57-inch mini display adopts chips in a size of 8μm, while the large signage display consists of chips that are 300μm long and 100μm wide.
Lumens will first unveil the combiner type of HUD for the automotive aftermarket this year and expand into the windshield or built-in type in cars in two to three years, said Jung.
Lumens reveals that the 0.57-inch display would use 921,600 micro-LED chips, and states that the process for large amount of chips is very critical.
