Apple Testing Touchscreen Panels for Future iMac?

DigiTimes claims that Apple has recently received samples of new touch panels that would be used in a new touch-capable iMac. These touch panels are typically produced by placing touch sensors over the panel, and then a cover glass over the sensors. Such method does not require any extraordinary costs and manpower efforts, but affects display brightness. The new iMac is rumored to have a good vertical and horizontal viewing angle, and its projected capacitive touch panel will decrease dimensions of future iMac and reduce thickness and weight.

First rumors of a touchscreen iMac appeared in January, with claims of a 22-inch model set to debut sometime during 2010. A second rumor surfaced in June claiming that Apple would be holding a special event to introduce a touch-enabled iMac running both Mac OS X and iOS within the following two months. But both of them failed to take place.
