Metal Oxide Thin-Film Transistors Are Key Enabler for AMOLED Displays, Reports NanoMarkets15 Aug 2012 • by Natalie Aster
After years of rapid growth, the flat-panel display (FPDs) industry is slowing down. This is due to sluggish economies worldwide, in part. But another force is at work too; market saturation. When LCDs first reached the market at affordable prices – some 15 years ago or so now – there was a huge installed base of CRT monitors and televisions just ripe for the picking.
Today, the old CRTs are mostly gone. The display industry is looking for new strategies to restore growth. One of these is to bring to market new display technologies that offer something that LCD cannot. The hope is that with the next big display technology hitting the market, consumers will be willing to swap out their old LCDs for “what’s next.” This might revive the display industry’s flagging fortunes.
The new report "Metal Oxide Thin-Film Transistor Markets" by NanoMarkets states that a successful new display technology must offer a sufficient improvement over LCD and at an attractive enough price to incent consumers to behave as the display makers would like them to. This is not an easy goal to achieve when one considers that LCD can now boast a couple of decades of manufacturing and product engineering experience to its credit.

If AMOLEDs cannot be deployed for large-area applications, then, by definition, AMOLEDs cannot replace LCDs as a dominant display technology. Worse, if AMOLEDs are restricted to small mobile displays then economies of scale for both OLED material manufacture and the production of AMOLEDs themselves cannot kick in, again thwarting high hopes for AMOLED technology. NanoMarkets believes that the technology that will cut through this Gordian knot are backplanes that are based on metal oxide thin-film transistors (TFTs). Such TFTs will also be sold into the conventional LCD sector and will generate more revenues from LCD applications than for AMOLED applications. But in the AMOLED sector, they will be more essential and will prove a key enabling technology for AMOLEDs. Here’s what metal oxide TFTs can offer the AMOLED business.
- A high mobility, with big enough currents to drive AMOLED displays and respond to the higher refresh rates of next generation displays;
- Relatively cheap large-scale production, that is easily scalable to large substrates;
- Small pixel sizes and hence, high-resolution displays; and
- Larger aperture ratios compared to a-Si, allowing for higher transmission through the backplane which can increase the brightness of the display without an increase in power requirements.
