The 12" Retina display on the MacBook doesn't just have a high resolution, but it's also paper thin. In fact, it is just 0.03" (0.88mm). A specially developed automated manufacturing process forms the edge-to-edge glass that's only 0.02" (0.5mm) thick. And Apple reduced the space between display components for a tighter, more integrated design. The Retina display has a 2304 x 1440 native resolution and a 16:10 aspect ratio. It also has 178° viewing angles, thanks to its IPS panel.
To deliver the Macbook's Retina experience, Apple redesigned the pixels to create a larger aperture, allowing more light to pass through. This enabled them to use LED backlighting that's 30 percent more energy efficient than the Retina display on previous models while still achieving the same level of brightness.
Force Touch Trackpad
The Force Touch trackpad may look like other trackpads on the surface, but it's what is underneath that makes it distinct. Force sensors detect how much pressure you're applying, and the Taptic Engine provides a click sensation when you press anywhere on the surface. Now, the click that once was a single, mechanical function is just the start of what you can do with Force Touch.
The sensory capabilities of the Force Touch trackpad allow you to tell your MacBook what you want it to do based on subtle differences in the amount of pressure you apply. This makes it possible to perform a variety of different actions in different apps, all on the same surface. And it can respond with haptic feedback you can actually feel, making your MacBook more usable and personal.
