Apple has won US rights to a pair of potentially important patents, reports observe. The first -- Touch screen liquid crystal display -- describes what is better known as an in-cell touchscreen, embedding touch sensors into an LCD instead of a separate layer. Most screens continue to sandwich multiple layers, including those used on Apple devices like the iPhone 4S and third-generation iPad. Apple has, however, been rumored as switching to in-cell tech for the next iPhone, which could ship in late September.
