How it's Made: iPhone Displays

How it’s Made: iPhone Display

Displays are the most common component to fail on an phone. They are the cutting edge of technology, the gateway to our world, and very fragile. To the layman it is one unit, to the technician it is many, and to the manufacturer it is hundreds. We are going to break some of these components down and learn more about what they do!

Cover Glass:

The first layer is the cover lens. A clear piece of glass that allows light, and electrical impulses through while protecting our expensive LCD panels underneath. It starts as a single block of glass the size of a container. Often made in Germany or in the United states these are shipped by ocean liner to cutting facilities in China where they are cut into large sheets and then stamped into their respective sizes. After they are sized properly the coating and polishing processes are started. what we are left with is the corner stone of our repair industry.

For Corning glass specifically it undergoes some proprietary chemical treatments to strengthen the glass. One of these commonly known as a ION Exchange bath uses a molten alkaline potassium salt.

OCA:

OCA is the adhesive used to bond the cover glass to the LCD panel. Optical bonding (vs No bond like the 3GS) improves the contrast ratio by reducing the amount of reflected light, thus improving view-ability  It also improves the durability of the cover lens.



 

Polarizer:

“Light is made of particles called photons, which travel through space like a wave, zig-zagging back and forth on their way to your eye. Natural, unpolarized light

consists of photons bouncing in many directions at once. But as soon as they strike certain types of reflective surfaces—like a body of water or an asphalt road—those waves will all begin vibrating in one direction, usually horizontally. This is what causes the intense glare that hurts your eyes when you look at sunlight on a lake.
