Touchscreen Innovations Drive Down Costs


When it comes to manufacturing a mobile device, the touchscreen is one of the most expensive components. The touch panel and display can represent up to 25 percent of the total manufacturing cost of a smartphone with a 3.7-inch screen—and up to 40 percent of the manufacturing cost of a high-end tablet with a 10.1-inch screen.


As demand grows for 4-inch and larger smartphone screens, smartphone vendors are more motivated than ever to reduce these costs, and component manufacturers are responding. Several screen makers are working on thinner, lighter, and more cost-effective screens using a one glass solution (OGS).


Traditional touchscreen displays feature touch sensors that are placed over the display panel and then covered with glass. This is a complex and expensive process that also affects the brightness of the display.


With OGS, indium tin oxide (ITO) is deposited in a thin film on the touchscreen glass, creating a transparent conductive coating. Several manufacturers have developed OGS products. Corning, maker of Gorilla Glass, has an OGS product called IOX-FS, and Taiwan-based Wintek has recently increased its production of OGS. HTC, Nokia, Samsung Electronics, and several Chinese ODM manufacturers use Wintek OGS displays.


Using OGS will not only help smartphone vendors reduce costs but will also allow them to put out thinner devices, even as the devices’ screen sizes increase. Another benefit of OGS is that it allows for wide viewing angles. Wintek has indicated that 20 percent of its 2012 touch panel shipments will be OGS-based.


Researchers continue to explore other alternatives to traditional touchscreen displays, including carbon nanotube conductive coatings.



Intel Gears Software Developers Up for Windows 8


Ahead of Microsoft Windows 8 general availability, Intel has updated 2 toolkits for application developers—Intel Media SDK 2012 R3 and Intel SDK for OpenCL Applications 2013 Beta.


In addition to Windows 8, Intel Media SDK also supports DirectX 11 with optimized access to hardware-accelerated video encoding, decoding, and transcoding for applications on 3rd Generation Intel Core™ processors.


The Intel SDK for OpenCL Applications Beta now supports OpenCL 1.2 API previews on CPU and other features such as a new kernel builder and GNU project debugger, which ease the creation of parallel and visual computing apps. Both kits support the new Intel HD Graphics Driver for Windows 8 and are available now as free downloads.​
