After some careful spudgering, the display assembly comes free without much of a fight.
The display assembly weighs in at a whopping 60 grams—a 15 gram increase over the one found in the iPhone 6. In fact, that's the same weight as the much larger display on last year's 6 Plus! The additional capacitive sensors that Apple integrated into the display backlight have really beefed this thing up.
Save for the reduction in cables, and a slightly different LCD shield plate design, the old and new display assemblies seem pretty visually similar.
