JOLED ships 21.6-inch 4K OLED display

Japanese display firm JOLED introduced its first product, the company started shipping a 21.6-inch OLED panel with a 3840 x 2160 pixels resolution. The 4K panel has a 204ppi pixel density, 350 nits brightness, and a 1,000,000:1 contrast ratio.

Reuters reports the first panels were shipped to Sony for use in medical screens. The special thing about this OLED panel is how it was manufactured, JOLED makes its screens using a lower-cost printing process. The firm claims this saves 20-30 percent in costs versus traditional OLED manufacturing methods:

JOLED is the world’s first OLED maker to market screens which use a lower-cost printing process, where organic color materials are deposited onto glass substrates in a way similar to ink-jet printing.

The printing method can produce OLED screens 20 percent to 30 percent cheaper than the current evaporation process as it doesn’t need vacuum chambers and metal masks for depositing colors, Yoneharu Takubo, JOLED’s technology chief, said at a news briefing.

“We eventually want to make the printing method a de facto standard” for producing OLED panels, Takubo said.
