Vitex developed a moisture barrier film used for OLED encapsulation called Vacuum Polymer Technology (VPT). The company says that their barrier is equivalent to glass in terms of water or oxygen penetration and can be applied to flexible substrates or over a finished display.

Vitex has licensed its IP to several companies and in December 2008 said that Samsung, UDC, LG and other companies are all using VPT in OLED products and prototypes. In June 2006 we interviewed Vitex's sales & marketing director.

In 2010, Vitex was acquired by Samsung Mobile Display.

The latest Vitex news:

Vitex expands ANS agreement, Samsung SDI uses their systems

Vitex System today announced that it has expanded its license agreement with Korea-based Advanced Neotech Systems (ANS), granting ANS rights to develop and manufacture roll-to-roll coating equipment used in the production of Barix™ Barrier Film.



Vitex made the first agreement with ANS in 2006, allowing ANS to make Barix encapsulation equipment, the Guardian™ System. ANS has successfully sold eight Guardian systems to produce Vitex's proprietary Barix technology, including: a pilot system being used by Samsung SDI to make the world's first foldable OLED and the thinnest OLED display that was shown at FPD International 2008 in Yokohama; the first mass production system; and the first Gen 2 (370mm x 470mm) system. 

Over the past year, Vitex has made excellent progress demonstrating the unique capabilities of its Barix Barrier Film for encapsulation of thin-film photovoltaic cells. Multiple companies have been able to verify that, when protected by Vitex's Barix Barrier Film, their thin film photovoltaic (PV) cells fabricated using either CIGS or CdTe can pass the damp heat test required by the IEC 61646 standard. 

Vitex compiled a short video presentation with OLED displays that use their technology

Vitex has produced a nice video of several OLED products that use their thin film encapsulation technology. Among those products you can see the Samsung's flapping display, foldable phone and curved displays. Several UDC OLED prototypes are in there as well, including their flexible displays, developed together by LGDisplay.

Vitex told us that their tech is used on AMOLED and PMOLED displays, on glass, silicon or metal foil. Some of those products use direct encapsulation, and some use barrier substrate. A few of the photos seen show products that use flexible CIGS PV cells laminated with Vitex's barrier.

Vitex and Novaled Will Cooperate on OLED Thin Film Encapsulation

Vitex and Novaled are going to combine advantages of the Vitex Barix thin film technology with the Novaled doping technology and materials targeting very thin and high efficiency long lifetime OLED products.

The majority of OLEDs are currently processed on glass substrate and encapsulated with glass for protection against air and moisture. The glass represents more than 90% of the device thickness. Vitex has developed an innovative thin film encapsulation targeting ultra thin OLED devices.

Vitex Systems Signs Licensing Agreement With Sunic System

Vitex Systems announced that it has signed a licensing agreement with Sunic System. The agreement includes a technology transfer package from Vitex to Sunic, and gives Sunic the non-exclusive rights to make and sell Guardian(TM) thin-film encapsulation systems, which can be used to encapsulate various electronic components and devices, including organic light emitting diode (OLED) displays, thin film solar cells and thin film batteries. While the financial terms of agreement were not disclosed, the license includes an upfront fee and on-going royalty payments based on tool sales.

Vitex granted several new patents recently

Vitex was granted six new patents recently. These new patent grants bring Vitex's owned or controlled patents to a total of 127. This solidifies the company's IP portfolio following its successful reinvention as a licensing and technology development company-a move achieved by leveraging its leadership position in thin-film encapsulation for flexible substrates and organic light emitting diode (OLED) displays.

The recently granted patents are directed at protecting the unique technology Vitex has developed for edge sealing on OLED displays and other electronic devices, as well as for unique tool apparatus needed for the deposition of the proprietary thin-film encapsulation. The six patent wins comprise two each in Europe and China, and one each in the United States and Taiwan.

While the display market continues to be Vitex's primary focus, the company is applying parallel applications to the rapidly emerging thin-film photovoltaic market, which has a strong need for a superior low-cost, thin-film encapsulation.

Vitex's Barix Solution Maintains Superior Moisture and Oxygen Barrier Integrity at High Temperatures

Vitex Systems today announced its proprietary moisture and oxygen barrier solution demonstrated impressive reliability results when used for high-temperature applications. The company's revolutionary Barix(TM) thin-film barrier was continuously tested at 100 degrees C, 120 degrees C and as high as 140 degrees C for more than 500 hours without losing its barrier integrity. Moreover, results indicated that the barrier can maintain its integrity for more than 1,000 hours in this severe environment.

Vitex's Barix thin-film barrier uses an organic and inorganic multi-layer structure. To demonstrate product compatibility, it was used to create the world's first high-resolution AMOLED, which leverages an amorphous silicon backplane on a flexible metal foil. This flexible display -- jointly developed by Universal Display Corp. and LG. Philips LCD -- was showcased at last month's Society for Information Display (SID) conference in Long Beach, Calif. Similar encapsulation was shown by Samsung SDI on the world's first, and thinnest, full-color top emission AMOLED on a metal foil during last year's show.
