University of California, Los Angeles (UCLA) researchers say they have developed a device that could lead to a significant leap in the quality of images on smartphones, computer displays, TVs, and inkjet printers.
The device includes a new material and a new manufacturing process that are used to produce semiconductors essential to liquid crystal displays and organic light-emitting diode displays.
"Our semiconductor process is faster, less expensive, and more reliable than existing processes," says UCLA professor Yang Yang. "We strongly believe it can be used as a technology to replace existing processes and scale up production of thin-film transistors."
Yang notes the device offers mobility that is 10 to 20 times greater than that of an amorphous silicon-based thin-film transistor (TFT). The device, which is composed of indium gallium zinc oxide and indium tin zinc oxide, has channels that are designed differently than those in other TFTs. "Our device's performance is comparable to that of commercial TFTs, but it can be produced at a much lower cost," says UCLA researcher You Seung Rim.
