Yesterday Apple announced two new devices - the iPhone 7 (and 7 Plus) and the new Watch Series 2. The new Watch is Apple's 2nd-Generation smartwatch that has several improvements over the first generation - including a built-in GPS, waterproofing and better hardware.
We're mostly interested in the display, of course, and the Watch 2 display features the same size and resolution as the first generation - either 272x340 38mm or 312x390 42mm. The main improvement in the new display is that it is twice as bright at 1,000 nits (the original Watch's display had 450 nits).
For the first time ever, Apple finally admits that this is an OLED display. This is great, and hopefully it means that Apple is ready to admit that OLED displays are better than LCDs. It is likely that the new display is again a flexible AMOLED made by LG Display.
The new iPhone has many upgrades compared to the iPhone 6, but the iPhone 7 and 7 Plus still use LCD displays, unsurprisingly. The iPhone 7 has a 4.7" 1334x750 (326 PPI) IPS LCD and the 7 Plus has a 5.5" FHD (401 PPI) display. Hopefully the next iPhone iteration in 2017 will finally adopt an OLED display - even if only at a new premium edition.
