Peeling the LCD from the articulating bracket reveals a PCB packed with passives.

This little circuit board is probably a breakout board for the LCD, allowing for a thinner cable from the camera.

The capacitors probably reduce noise in the display; they're clearly visible as a little cluster of dark spots in this X-ray image, courtesy of our buds at Creative Electron.

Display technology is finally close to passing its Turing test: being indistinguishable from the mirror views in high-end cameras. This leap in tech has allowed for the viability of mirrorless cameras like the A7 series.

Apple bills these as Retina displays, but since a camera's display has to be much closer to your eye, the pixels have to be that much smaller to seem invisible.
