"Trouble Spots
There are still a few bugs that need to be sorted out. A major hurdle is the typically short life-span of OLEDs, compared to that of LCDs. At the current stage of evolution, OLEDs do not possess sufficient lifetime for 24-hour applications such as desktop computers and TV. But they are well suited for phones and PDAs, which are used on and off for several years.
Accordingly, companies are confining their OLED applications to devices that need low power consumption and high contrast ratio. Kodak, for instance, is mainly targeting small, portable electronic devices that require outstanding image quality, such as digital cameras, camcorders, advanced mobile phones, PDAs and portable entertainment devices.
Also, there are numerous problems with manufacturing and chronic color degradation. At this stage of its evolution, OLED technology still has to prove its viability in terms of quality.
In addition, OLEDs' much-touted advantage—low power consumption—scores only over backlit LCDs, like those used in laptops, and not displays lit by ambient light such as those in cell phones.
Rosy Picture
Owing to their faster response times, full color potential, and flexibility, OLEDs are likely to extensively permeate the communication segment. Demand for OLED displays will be driven by a surge in web-enabled cellular phone handsets, PDAs, portable entertainment devices, and automotive applications. In many of these devices, the display screen acts as a differentiating feature and constitutes the most expensive component. OLEDs are likely to bring down the cost of display screens thereby reducing the price of products and enabling wider market reach.
The potential market for LCDs is worth billions of dollars. Conservative estimates
project that OLEDs may capture 5 per cent of the FPD (Flat Panel Display) market by
2005. However, the industry is still at the stage of understanding the chemistry and
Physics of these materials and the growth of the OLED display market are going to be a long-drawn-out process.
