To create a continuous surface, where nothing comes between you and your experience with the device, we replace the start button with new intuitive gestures. Just slide your finger up from the bottom to go to the home screen. True Depth camera allows you to take amazing photos and use Face ID. This miniature module only occupies a small space at the top of the screen, but it contains some of the most advanced technologies that we have developed. The OLED panel of the Super Retina HD screen is much more than a simple OLED. It is made to measure following our most rigorous standards to be able to create an HDR screen with a contrast ratio of 1,000,000: 1, high resolution and brightness, compatibility with a wide range of colors and the highest color accuracy in the entire industry. The iPhone X has a high dynamic range (HDR) screen. You can watch movies and series in Dolby Vision and HDR10. Your HDR photos will look even more incredible.
