With every passing day, you get to hear about all sorts of developments about new and emerging technologies. These technologies are developed in all spheres like computers, gadgets, storage devices, cameras, etc. In this race of new technologies, the Flat Panel Display technologies are also making their mark and are not lagging behind in terms of innovation and ideas. These days, there is a lot of talk about active matrix organic LED displays (OLEDs), touch screens, flexible displays, and portable projectors. It is being widely said that OLED displays and touch screens are surely the next big thing in Flat Panel Technology.
But a question that stills looms is if and when OLEDs will become a big part of the large display market. Currently a lot of small OLED displays are being provided on cameras and similar products. Recent products like Kodak’s picture frame and OQO’s mini-notebook feature OLED displays. These however are small sized displays. The only device in the market to sport a large size OLD display is Sony’s 11-inch OLED TV. These OLED displays formed less than 1 percent of the total flat panel display revenue in 2008. It is being widely speculated that this figure will rise multiple folds in the days to come. Companies like Samsung has already announced its 31-inch display based on the OLED technology.
The OLEDs are extremely light in weight and offer low-power consumption, excellent color gamut, and fast response time. The best part is that they can be made very thin, bendable, and transparent. If this technology booms, the overall cost of OLEDs will prove to be lower than that for LCDs. As these displays are currently made on smaller-size production lines, their production cost is expensive. Companies like Universal Display Corp. have decided to go for making phosphorescent OLEDs instead of the currently made fluorescent OLEDs.
One more area of development in the Flat Panel Display technologies is the increasing use of touch screens in the devices. These days there are over a dozen technologies on touch screen feature that range from resistive to surface capacitive to electron magnetic resonance. The market is growing these days to an exceptionally good “projected capacitive touch,” which is used in the iPhone. These innovations are surely going to take the Flat Panel Display technology to the highest level.
