The new iPad screen features 264 pixels per inch, providing the best display ever on a mobile device, Apple executives said during a product presentation in San Francisco broadcast live to reporters in London.
The new iPad -- the third version of the touchscreen tablet computer introduced in April 2010 -- also features a five-megapixel camera, a faster processor and high-definition video recording.
It will go on sale on March 16 at the same price as the previous models, which start at $499 for the most basic iPad.
Apple said the new iPad will also feature faster 4G LTE connectivity.
"Apple has its feet firmly planted in the post-PC world," Apple chief executive Tim Cook said, adding that "the iPad is reinventing personal computing" and spearheading the "post-PC revolution."
The new Apple TV box, which Apple said features a streamlined new user interface, will sell for the same $99 price as the previous model.
Apple released the first version of Apple TV in 2007 but it has never really caught on with the public.
