A tablet PC is a tablet-sized computer that also has the key features of a full-sized personal computer. Tablets are much thinner, lighter, and more power-efficient than conventional notebook computers. They are equipped with a rotatable touchscreen as an additional input device, and run a standard PC operating system like iOS, Windows, or Android. The user interface generally does not include a conventional keyboard and uses the display as a multifunction input and output interface. The hardware architecture of tablet PCs is similar to that of notebook computers, except that it handles much less power and generally has height and size restrictions. High efficiency at various load conditions provides the ability to overcome thermal challenges to help achieve miniaturization. Vishay offers leading-edge technologies to help with this efficiency improvement, as well as help to improve battery life and overall system performance.
