Apple sued over iPhone screen tech

Picsel Technologies alleges patent infringement for technology found in the iPhone and iPod Touch that lets people fluidly zoom and pan sites, documents, and images, according to reports.

Two related companies are suing Apple over screen rendering technology used in the iPhone and iPod Touch, according to reports.

Picsel Technologies and Picsel Research, based in Glasgow, Scotland, filed a patent-infringement lawsuit Friday in U.S. District Court in Delaware, Dow Jones reported. The suit alleges that Apple is violating a Picsel technology that accelerates the process of updating a device's display.

According to Macworld, the suit is focused on Picsel technology that people use to zoom and pan documents, sites, and images. Apple's devices wouldn't function as fluidly without the technology, alleges Picsel, which wants compensation for devices already sold.

Picsel's site says its customers include Motorola, Nokia, NTT DoCoMo, Palm, Samsung, Sony Ericsson, and Sharp. According to Dow Jones, Apple declined to comment.
