Kateeva in Bloomberg: Your Next TV Might Roll Out of a Printer

Kateeva’s inkjet equip­ment promises to drive down prices for OLED sets

Mak­ers of elec­tron­ics hop­ing to win over con­sumers with sharper, more vivid dis­plays are turn­ing to a screen tech­nol­ogy called organic light-​​emitting diodes (OLEDs). Con­sum­ing less power than liquid-​​crystal dis­plays, or LCDs, OLEDs can also bend into all sorts of shapes. Sam­sung Elec­tron­ics uses them in its lat­est gen­er­a­tion of Galaxy smart­phones, and LG Elec­tron­ics fea­tures them in its top-​​of-​​the-​​line TVs.

The industry’s migra­tion away from LCDs has cre­ated an open­ing for Kateeva, a Newark, Calif., com­pany that’s devel­oped an inkjet-​​printing method to pro­duce OLED dis­plays. Kateeva, whose name comes from the Hebrew word for “writ­ing,” has raised more than $200 mil­lion in ven­ture cap­i­tal since it was spun off from an MIT lab in 2008. Investors include Sam­sung, Spark Cap­i­tal, and TCL Cap­i­tal, the ven­ture cap­i­tal arm of one of China’s lead­ing elec­tron­ics com­pa­nies. “We feel OLED is the future,” says Tong Xuesong, vice pres­i­dent of TCL.

Mak­ing OLED dis­plays large enough for TVs is dif­fi­cult, which is one rea­son a 65-​​inch 2016 model OLED TV from LG sells for $4,000, more than twice the price of a com­pa­ra­ble LCD set. The process starts with punch­ing tiny holes into a metal sten­cil called a mask; the mask is then placed over a back­plane and sprayed with the organic com­pounds that form the OLEDs. Slow and costly, it wastes a lot of mate­ri­als that end up on the sten­cil rather than the display.

Kateeva’s equip­ment, which isn’t com­mer­cially avail­able, can be more effi­cient, because it prints directly onto the back­plane. The startup has teamed up with DuPont and Sum­it­omo Chem­i­cal to develop OLED inks suit­able for its print­ers. The specs are exact­ing: The layer of mol­e­c­u­lar com­pounds deposited by the inkjet must be no more than 50 nanome­ters thick and able to dry within 90 sec­onds. With inkjet tech­nol­ogy, “there can be a printed OLED tele­vi­sion in the mar­ket for $1,000,” says David Flat­tery, dis­plays busi­ness man­ager for DuPont Elec­tron­ics & Com­mu­ni­ca­tions. “That’s what we’re targeting.”

Kateeva co-​​founder Conor Madi­gan dis­misses some of the OLED TV sets on the mar­ket today as “half-​​OLED” because they rely on a fil­ter to dis­play col­ors. That makes the screen thicker and dilutes the sharp­ness, he says, explain­ing that Kateeva’s inkjet can print red, green, and blue pix­els indi­vid­u­ally, which sim­pli­fies the pro­duc­tion process. “I can go from 20 machines and drop it down to 3,” Madi­gan says. In a state­ment, LG Dis­play said its OLED man­u­fac­tur­ing method cre­ates dis­plays that use less power and have bet­ter colors.

Tokyo Elec­tron, a semi­con­duc­tor equip­ment maker, also offers inkjet-​​printing tools for OLEDs. But Kateeva’s tech­nol­ogy is “more mature,” says TCL’s Tong. Alberto Moel, an ana­lyst with San­ford C. Bern­stein, agrees that Kateeva has an edge on rivals. Madi­gan and his team “have been pound­ing at it for years,” he says. “They are pretty far ahead.” Tokyo Elec­tron declined to comment.

Not everyone’s that bull­ish. OLED mate­ri­als are very sen­si­tive to mois­ture; fig­ur­ing out a way to put them into an ink that can work in a printer is a major chal­lenge, accord­ing to Jerry Kang, an ana­lyst at IHS Markit, an indus­try researcher. IHS projects that OLED sets will make up 2.3 per­cent of the TV mar­ket glob­ally by 2020, up from just 0.4 per­cent this year.

Kateeva will begin fill­ing some orders for its print­ing equip­ment next year, Madi­gan says, and expects to go into com­mer­cial pro­duc­tion by late 2018 or early 2019. “We are com­plet­ing the design work for the first gen­er­a­tion,” he says. “That’s our home­work over the next year and a half.”

The bot­tom line: Kateeva, a startup that counts Sam­sung among its back­ers, has devel­oped an inkjet-​​printing method for mak­ing OLED displays.
