There are reasons why Apple has made such huge impact on global smartphone market. The iPhones of Apple are designed with excellence and finesse. The architecture of the iPhone LCD screens will simply blow your mind. There are some genius idea and very hard labor behind these special LCD screens. After reading this article, you will understand why the iPhone LCD screens are so expansive. If you have broken your iPhone 6s LCD screen and thinking about buying a replacement, , then it is compulsory for you to have sound knowledge about iPhone LCD screens. At present, there are so many fraud sellers in the market.
That’s why you should wisely choose your wholesale supplier. GTELCD is a great online store to buy iPhone LCD screens from. Their replacement screens work as well as the original iPhone screens. However, proper knowledge about iPhone screen can definitely enable you to detect the fraud sources.

The iPhone screen is presented on the diagram in a simplified manner. The iPhone LCD screen has a bar/sandwich like structure. The main structure can be divided into 3 parts i.e.
The glass/display
Digitizer panel
Liquid Crystal Module
The glass is the uppermost portion of the LCD. It is the exposed portion which you can see from outside. Under this glass, there exists a Digitizer panel. It is divided into 7 bands. The 1st, 4th and 7th layers are the OCA layers. OCA means Optically Clear Adhesives. It is otherwise known as the glue. The 2nd and the 5th layer are the conductive coating layer. The 2nd conductive coating layer is known as X Channel and the 5th conductive coating layer is known as the Y Channel. Finally, the 3rd and 5th layers are the PET Film layers. PET is the short form of polyethylene terephthalate.
That was the P-N-P junction structure of iPhone LCD screen. If you learn about the physical structure of the iPhone LCD screen, the whole concept will be clearer to you.

There are 6 distinct sheets assembled together to form the iPhone LCD screen.
The first sheet is the Backlight Unit. Backlight unit is a form of illumination used
in liquid crystal displays (LCDs). As LCDs do not produce light by themselves,
they need illumination (ambient light or a special light source) to produce a visible image. Backlight unit illuminates the LCD from the back of the display panel.
Above the Backlight Unit, there is a Polarizer sheet. A polarizer is an optical filter
that lets light of a specific polarization pass and blocks waves of other
polarizations. It can convert a beam of light of undefined or mixed polarization
into a beam of well-defined polarization, that is polarized light. Above the
polarizer sheet there is a ‘TFT Array’ sheet. A thin-film transistor (TFT) Array is a
special kind of field-effect transistor made by depositing thin films of an active
semiconductor layer as well as the dielectric layer and metallic contacts over a
supporting (but non-conducting) substrate. Above this layer there is a layer of
liquid crystal substance. Liquid crystal substance flows like a liquid but has some
degree of ordering in the arrangement of its molecules. The next layer is the Color Filter layer. Color filter layer is needed because the typical photo sensors detect light intensity with little or no wavelength specificity, and therefore cannot
separate color information. The last layer which lies above the Color Filter layer is another Polarizer layer.

Those two structures above make the iPhone structure very clear but it is also
imperative to learn about iPhone’s self healing structure. The self healing structure is a unique characteristic of iPhone. There are 6 special features of this structure which enables the process of self healing. The first feature is the Anti-Stain Coating. This coating prevents stain on the screen; It is placed on the top of the screen because the exposed layer needs this anti-stain feature. Under this layer there is a layer called ‘Auto-Healing Coating’. This coating is made of self-healing materials. Self-healing materials are a class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. The next layer is the Polyester Film. It is made of polyethylene
terephthalate. The fourth layer is the printing layer. Under this layer there is a very important layer which is made of adhesives. The layer is called the OCA layer. The last self-healing layer is the Silicon Adhesive layer. Based on elastomeric technology, silicone adhesives offer unparalleled flexibility and exceptionally high heat resistance.
