Schematic Purportedly Shows Next-Generation iPhone Front Panel Design with 4-Inch Display

Earlier today the repair firm iLab Factory has posted what is claimed to be a design schematic for a next-generation iPhone front panel part. The schematic matches up closely with leaked part photos, showing a taller display and the FaceTime camera above the device's earpiece.

The "active area mask" corresponding to where the device's display will be attached measures 90.1 mm (3.55 in) high and 51.42 mm (2.02 in) wide. This corresponds to an opening measuring approximately 4.08 inches diagonally, but iPhone viewable display areas have historically measured slightly smaller than their corresponding front panel openings. Consequently, this part would seem to nicely accommodate a display measuring 4 inches diagonally at an aspect ratio of roughly 16:9, in line with rumors of and evidence for a taller screen that maintains the width of the current model.

The schematic does not show an exact total height for the part in question. However, iLab Factory  suggests that the overall height of the part is roughly 122 mm, approximately 7 mm taller than the overall height of the iPhone 4S.
