Hydis launches new touchscreen technology: On-Cell Touch for LCD

Here is the press release:

-South Korea-based TFT-LCD panel maker Hydis Technologies, a subsidiary of Taiwan-based E Ink Holdings Inc., today announced that they will add on-cell touch screen panel (TSP) technology to their LCD portfolio of offerings.

“With on-cell touch, we are able to combine the best LCD in the world with a touch technology that offers better performance at lower cost.”

Hydis is able to offer the TSP technology with on-cell touch, which provides the customer a slim and lightweight form factor, with the added benefit of lower cost versus traditional touch technologies. The touch functionality is embedded within the display itself rather than as a separate component atop the display. This results in more precise touch with better optics due to reduction in parallax errors. In addition, LCDs with this touch technology consumes less power and can take advantage of cost reductions in manufacturing due to the reduction of a glass layer and the alleviation of the need for a separate touch panel supplier.

Hydis will begin offering the on-cell technology to the smartphone and tablet markets beginning this month. Hydis is perhaps best known as the inventors and providers of Fringe Field Switching (FFS) technology, which is featured in many smartphones and most tablets currently in the market. FFS LCD provides a wider viewing angle and color gamut, consumes less power and offers better high ambient readability than traditional LCDs. Hydis’ publicly announced customers include Dell, HP, Lenovo, Kobo & Siemens, among others.

“Hydis’ FFS technology is preferred by Tablet and Smart phone makers worldwide,” said Johnson Lee, Chairman of Hydis Technologies. “With on-cell touch, we are able to combine the best LCD in the world with a touch technology that offers better performance at lower cost.”

Is this new touch screen technology really better and cheaper than capacitive? Hydis's Fringe Field Switching (FFS) technology is already in use by for example the iPad and other popular LCD tablets. Does it support multi-touch? Does it support pen input? Is it really more precise than capacitive? I look forward to try it out. Perhaps Hydis will show it off at Computex next week? I'll be video-blogging 50 or more videos from Computex next week so check back for those.
