Remove a couple screws and pull the headphone jack out of the rear case.

As with most portable devices, the headphone jack is very well fastened to the case.

The microphone's right next to the headphone jack and goes through the same data cable as the headphone jack.

Like the iPhone, it appears that the iPad features a liquid sensor in its headphone jack. If you get your iPad wet, don't expect Apple to fix it under warranty for you.

Ants on parade? Nope, just the T4 Torx screws holding each tab to the display assembly.

• Each clip holding the display assembly to the rear case is fastened down with its own T4 Torx screw.

Luckily, the home button is a digital switch with its own circuit board, making replacement that much easier.

Disassembling the display assembly.

A thin ribbon cable connects the LED driver board to the LED backlights.

The LED driver circuitry and the interconnects between the actual LCD and the display data cable connector are contained within the same circuit board.

The ambient light sensor lives in a compartment that a camera would love to call home.

We suspect that this compartment was intended for the ambient light sensor all along, and the rumors of a camera that would fit here were overzealous. The layout does look very similar to the camera's view ports on the MacBook Pro 13" Unibody.

The display seems to be glued around its perimeter but can still be removed from the plastic framework.

The display assembly weighs in at:

• 153g for the LCD
• 193g for the front glass

The glass seems quite thick (~1.18 mm), which is not a huge surprise considering the size of the iPad. Compare that to about 1.02 mm for the iPhone.

• The iPad would require thicker glass due to the increased "lever arm" caused by pressing down at the center of the screen. This is analogous to the difficulty of bending a one inch section of a ruler compared to bending the entire twelve inch ruler.

Some front glass/digitizer part numbers.

The part number on the display frame reads:

• HIA097NRFE0XA

On the digitizer cable:

• 821-0757-A

Peel back the sticker, and more part numbers can be seen near the bottom of the LCD.

The numbers read:

• A01327200 EP001A
• 10 1 25 S NE M213

We don't know who made this particular LCD. Do you? Another iPad we opened contained a LCD panel that was manufactured by LG.
