Transparent OLED displays are among the subjects nowadays that are frequently undergoing the process of innovation. The integration of the OLED display technology started in mobile devices, including Smartphones and it did not take long before this technology was finally used on other gadgets and items that consumers now greatly appreciate, especially in TVs. Such technology is recognized for its featured thin, bright and efficient display. Generally, the materials used in OLED technology are transparent. From this, fabricating of transparent OLEDs or the TOLEDs became possible and is now already integrated in some products present on the market.
OLED technology’s use is not only focused on mobile phones, TVs and digital cameras. It can be used in creating transparent OLED lighting panel and simple lighting panels, but the most interesting use of this technology is that can make something look invisible when not being used. It is the exact thing that happens to OLED TVs applied with the technology. Unfortunately, the use of such transparent displays is still limited at this point and some of these few applications are:
Available Products on the Market that Use the Transparent OLED Displays
The first ever related product that used this technology was Samsung’s IceTouch media player. It is considered as the first TOLED device in the world, which the company planned on launching, but decided not to pursue. From there, the period of TOLED industry started and now, there are already two major players in this field: Neoview Kolon and Futaba. Remember S-800 by Lenovo? This product was the first TOLED product ever released in the market and it used the 2.4” QVGA TOLED panel by Futaba. The second product was the Indonesian Nexian Glaze M-9090, which used NeoView-Kolon’s 2.4” panel.
Right now, the major players in the industry of technology are working on innovating larger transparent AMOLED displays. These major players are LG and Samsung. Talking about LG, the company recently launched a new innovation in relation to this field. This is the:
LG’s Innovation – Transparent and Flexible OLED Displays said to be the Start of the E-Paper Revolution
LG had been long part of the transparent OLED displays industry. In fact, they started with the flexible E-ink display in 2012 followed by the G-Flex Smartphone, which used OLED display that was slightly flexible. Today, this line of innovations is now added with a new one on the list. This product is the massive 18 inches OLED display which can easily be rolled-up in a tight cylinder. It only features a three-centimeter radius or about 1.2 inches. This new innovation was just showcased last July 2014. It is simply a prototype, but it already boasts so many exciting features. These features include its 30% transmittance, which the company arrived with the use of their very own transparent pixel design technology.
LG is also proud to state that they have already succeeded in lowering the panel’s haze, which they did through utilizing film components that have about 2% level and circuit devices. In this development, the company not only succeeded in lowering the haze in the panel, but also in improving the transparent display’s technology level. When compared to other transparent OLED displays, it can be easily noticed that LG’s new innovation offers greatly improved transmittance. The main purpose of the company in arriving with this improvement is to offer transparent OLED displays that are ultra HD-flexible. Aside from this, the company also announced their highly transparent 18-inch OLED display. The company also thinks and aims to combine both of the prototypes’ primary features – transparent and flexible displays and present a prototype integrated with both by 2017.
What is this Newly Innovated Transparent OLED Display Developed by LG?
The innovations that LG recently unveiled features two convenient designs that consumers would certainly love and would soon become the trend in the modern times when it comes to the OLED technology. The first prototype it unveiled is an 18-inch OLED panel that features a transparent display and the second one is an 18-inch OLED panel display that can easily be rolled-up. The company believes that such panels can bring in a new a technology in TVs, one that can easily be rolled specifically those that measure about 50 inches and more.
It comes with many exciting new features as well. First one on the list, this transparent OLED display has a 30R changeable curvature, which further enables the rolling up of the panel into a cylinder. This can be enabled without even affecting its 1,200×810 pixel display. The company arrived at this level of flexibility with the use of a film that has a high molecular substance that is based in polymide for the backplane. This material is used instead of a conventional plastic, which effectively brought significant results in the form of reduced thickness in the panel. Hence, the panel’s featured flexibility. The polymide material is a type of flexible and strong plastic and is extensively used in today’s electronics industry.
Yes, it is still unlikely for consumers to find any commercial product that uses this kind of transparent OLED displays in the market. The company has already integrated part of this technology in the creation of the curved LG G-Flex. However, it will still be a long way before an appliance or any device that is completely flexible can be developed. LG has some good news for those people who wish to be kept updated with their developments in the field of transparent OLED display. They will have a taste of another related innovation after a few years, so they should be prepared of it.
LG’s Plans for the Future
The announced prototypes are already big steps forward, but that does not stop LG from taking more steps seeing that it already has a plan laid out for the coming 2017. This plan entails the creation of an OLED display that has a size of 60 inches. The company plans for the prototype to combine the recent features, which are the transparency and flexibility of the panels. They also aim to integrate UD resolution, about the 4k, 3840 x 2160 levels. From these innovations, LG can now take that step that will allow them to lead the display market in the future.
