What Are AMOLED Display and Gorilla Glass of Smartphones?

AMOLED Display and Gorilla Glass Has Been Popular Out of Marketing by the Companies. What Are AMOLED Display and Gorilla Glass of Smartphones? In very short – AMOLED Display is a display technology like OLED, TFT-LCD are display technologies. Basic is any type of LED display is one multi color RGB LED controlled by a programmable micro-controller, multiple RGB LED controlled via multiplexing. Up to RGB LED display is what we can do with Arduino to built DIY color display unit. After that, the individual units become too small SMD components. As they many a times AMOLED Display and Gorilla Glass co-exist in advertisements for the display units of modern Android smartphones, we thought to discuss them together in one article divided in two sub-headers.

 

What Are AMOLED Display and Gorilla Glass of Smartphones : First Discuss Easy Gorilla Glass

 

Corning Inc is an 167 years old company who manufactures patented glass related things like yellow colored headlamp lenses of automobile. Today after 100 years, that yellow colored headlight seems ordinary. Corning is a glass expert company themselves with huge resources :

They have memberships too :

Those are for glass-making art like shown in Discovery Channel, National Geographic, History etc international television channels.

Gorilla Glass is a branded toughened or tempered glass. Tempered glass glasses upon fracture stress does not splinter into jagged shards plate glasses but cause the glass to crumble into small granular chunks. These glasses are most susceptible to breakage due if extra stress applied to the edge of the glass. But shattering can also occur in the event of a hard impact in the middle of the glass.

Gorilla Glass is simply a branded scratch resistant touchscreen glass. Corning is manufacturing similar tempered glass since 1960s, which are used for both industrial and commercial fields. In 2005, 2008 they introduced newer type of tempered glass. Gorilla Glass is an alkali-aluminosilicate thin glass designed to function as protective cover glass for smartphone display (in our current context). That Gorilla is made by a proprietary process named Corning’s fusion draw. Gorilla Glass does not interfere with Capacitive Touch Screen. Gorilla Glass has versions and Gorilla Glass 5 is towards latest version. Corning has full lists unless smartphone manufacturer not allowed to publish :

2.5D glass is kind of generic version of toughened glass for smartphones which can have edges like Gorilla Glass. There are 3D Curved Surface Tempered Glass for J7 Max with videos on YouTube. That will give you an idea of “curved edges”.

Samsung, LG are working on plastic screens which can be folded and are lighter than Corning’s products. Gorilla Glass is exactly like Corning’s yellow colored headlamp lenses of automobile. It is important now, sells well; may be outdated in future.

Corning is good company but smartphone companies probably questionable about honesty.

 

What is AMOLED Display?

 

AMOLED stands for active-matrix organic light-emitting diode. We discussed OLED on this website before. There are several types of OLED which are being developed for incorporation into OLED monitors like Passive-matrix OLED (PMOLED), Active-matrix OLED (AMOLED), Transparent OLED etc. QLED (Quantum dot Light Emitting Diode) refer to non-organic solution that use Quantum Dots in place of phosphors for LED backlight.

AMOLED display consists of an active matrix of OLED pixels generating luminescence. AMOLED displays are notoriously prone to screen burn-in leaving a permanent feel of overused colors.

Super AMOLED is an AMOLED display with a layer that detects touch is integrated into the screen. Super AMOLED Advanced is for describing higher resolution, brighter display than Super AMOLED display. Super AMOLED Plus is energy efficient than Super AMOLED. Other terminologies like Full HD Super AMOLED, Quad HD Super AMOLED are nothing but slightly better versions like understandable from Super AMOLED like terminology.

 

Conclusion

 

As you can see, the marketing gimmick is more than real radical advancement of technology. Samsung Galaxy Note 8 possibly the best smartphone on this earth at the time of writing this article. But sad fact is that color of Note 8 will appear faded after a decade.
