Sony demonstrated two of its Micro-LED Crystal-LED "CLEDIS" integrated displays at ISE 2018. Sony's main displays at ISE was a large 8K x 2K Crystal-LED display, that reportedly was very impressive. Sony also demonstrated a small "Baby" Crystal-LED display, about 120-inch in size, at its booth.

According to Sony employees at the booth, the large CLEDIS took around 50 hours to build, and the cost of such a display is around $1.8 million. The smaller CLEDIS at around 120" will cost bout $500,000. I wish to thank Omar Ayers for providing the photos and the information from ISE.

Researchers from Korea's KAIST developed flexible vertical micro-LEDs (f-VLEDs) using anisotropic conductive film (ACF)-based transfer and interconnection technology.

The researchers developed their own transfer equipment and used it to fabricate a 50x50 array of f-VLEDs using simultaneous transfer and interconnection through the precise alignment of ACF bonding process. The researchers report that the micro-LEDs achieved an optical power density of 30 mW/mm2 - which is three times higher than that of lateral micro LEDs. The LEDs offer improving thermal reliability and lifetime by reducing heat generation within the thin film LEDs.
