JOLED Start Production and Shipment of 22″, 27″ and 32″ Monitor OLED Panels

Share this content

JOLED an OLED display expert and manufacturer of OLED by printing method, has started product shipment of its “OLEDIO OLED” displays (let’s see how many times we can make it clear these are OLED?!). It is the first mass production of OLED displays by this new printing method, which is different from the conventional vapor deposition method. JOLED will produce 10″ to 32″, medium-sized high-performance and high-quality OLED displays under the OLEDIO brand, for high-end monitors, medical monitors, automotive displays, and so on their press release says. This will hopefully mark the arrival of further desktop monitors using OLED technology, with shipment of the current panels in 22″, 27″ and 32″ sizes now under way.

New Printing Method Helps Simplify Production

JOLED is producing OLED displays using their new “proprietary TRIPRINT technology that forms an EL layer by printing RGB EL materials”. While the printing method requires advanced technical capabilities, it is expected to represent a major innovation in OLED display production, because its production process is simple and efficient, and it is adapted for medium- to large-sized OLED production, which is difficult using the conventional RGB vapor deposition method. JOLED has been carrying out R&D of printed OLED and started production in the pilot line in 2017. It started operation of mass production line in 2019 and has been making trial products. Now as of March 2021 JOLED will move from trial to mass production and aim at expansion of sales.

With JOLED’s proprietary TRIPRINT technology, RGB sub pixels are formed at once by printing. It is processed under atmospheric pressure without vacuum chamber nor metal mask. There is no material waste because it puts necessary quantity of materials onto target points by printing. The technology has also scalability merit because panels in variety of sizes can be manufactured with the same print head.

In the monitor market we expect to see initially panels in sizes of 22″ – 32″ including those that will be featured in the already announced LG OLED displays including their UltraFine 32EP950 and 27EP950 models. The display supplier currently has three OLED panels listed on its website: 22, 27, and 32-inch panels all with 4K resolution, RGB OLED pixels, and 1,000,000:1 contrast ratio as well as peak luminance up to 540 cd/m2.

These are likely to be restricted for now to very high end and expensive professional grade displays, although if the production really is simplified and improved then this could drive production costs down and make OLED a more viable panel option for other future monitors.

On Monday, March 29, 2021, JOLED held a product shipment ceremony at its Chiba site in commemoration of the product shipment from the mass production line. At the ceremony, Tadashi Ishibashi, Representative Director and President of JOLED, said: “We are so delighted to ship our brand-new OLED display OLEDIO from the world’s first printed OLED mass production line, which is full of our technology and expertise. I am filled with deep emotion when I reflect upon our journey from the establishment as a R&D company to today, overcoming several challenges, and finally reaching mass production. We will produce high-performance and high-quality OLED displays using the groundbreaking printing method and will provide innovations to the medium-sized category in the world OLED market.”
