Following debut half a year ago, Sony formally exhibits its CLEDIS (crystal LED integrated structure) display at CES 2017, fueling the interest in the emerging micro LED technology, which has become a hot topic in the industry.
As a self-illuminating display technology, micro LED is capable of light emission featuring disk-file addressing and single-point drive for every pixel, which entails the merits of high luminosity, low power consumption, and ultra-high resolution and color saturation. As a next-generation display technology, micro LED will facilitate micro-assembly technology being pushed by supply chain, which promises tremendous development potential, especially in the fields of wearables and indoor display. As a pioneer for the technology, Sony has rolled out CLEDIS display and is expected to start mass-producing the new product this year.
The achievement results from years of intensive R&D effort. Sony already unveiled crystal LED display technology back in CES 2012, which was still immature then, though, due to high production cost and inability for mass transfer, leading to low yield rate and extended manufacturing time. In 2016, the company altered its strategy focusing on the development of assembled-type CLEDIS display, which becomes an eye-catching exhibit during CES 2017 with its rich color and vivid image.
What Sony exhibits is a CLEDIS display with resolution up to 8K2K, featuring a giant 970cm x 270cm screen, assembled seamlessly with 144 40.3 cm x 45.3 cm micro LED modules. The assembly format facilitates the production of big-screen display and replacement of malfunctioned parts. The display, though, must be matched with contents with optimal resolution, in order to exhibit perfect images. Without the need of backlight and with black area accounting for 99% of the area surrounding pixels, CLEDIS screen is capable of displaying black images with contrast and purity even higher than OLED display, on top of better color exhibition. In addition, CLEDIS boasts wider viewing angle and wider color range.
Sony positions its CLEDIS display as a high-caliber large-sized commercial display, meant for application in movie theaters, large exhibition halls, and museums. Although Sony has yet to disclose price level, insiders note that asking price for a 220″ 8k display will top 120 million yen or US$1.03 million.
Should Sony CLEDIS large-sized displays enter mass production, demand for LED will spike, greatly alleviating existing oversupply problem. Meanwhile, Apple is expected to roll out micro LED wearables in 2018.
