The original IPS technology became a foundation for several improvements: Super-IPS (S-IPS) , Dual Domain IPS (DD-IPS), and Advanced Coplanar Electrode (ACE). The latter two technologies belong to IBM (DD-IPS) and Samsung (ACE) and are in fact unavailable in shops. The manufacture of ACE panels is halted, while DD-IPS panels are coming from IDTech, the joint venture of IBM and Chi Mei Optoelectronics – these expensive models with high resolutions occupy their own niche, which but slightly overlaps with the common consumer market. NEC is also manufacturing IPS panels under such brands as A-SFT, A-AFT, SA-SFT and SA-AFT , but they are in fact nothing more than variations and further developments of the S-IPS technology. In 1998 production started for Super-IPS panels, and were mostly produced by LG.Philips (now LG.Display). They have gone through several generations since their inception. Initially S-IPS built upon the strengths of IPS by employing an advanced “multi-domain” liquid cry...

For different model of iPhone, some suppliers are different. But the main suppliers are almost the same for all models of iPhone. Anyway, let's take iPhone 6s for example.

Now so many mobile phone screen technology, I'd like to introduce various display panel and screen technology, to make everybody can distinguish them easily. At present there are only two mobile phone screen classification, TFT - LCD and OLED, They respectively represent the passive and active display screen.Passive panel need the support of the back light, Active panel can self-illuminate and need no back light. OLED mainly represented by Samsung Super AMOLED（Super Active Matrix Organic Light Emitting Diode. TFT-LCD include: TN、VA、IPS、CPA（AVS） TN(Twisted Nematic)-- Low-cost make it is one of the most widely used screen. but the disadvantage is that small visual Angle, color reduction ability is limited VA(Vertical Alignment)-- It doesn't suitable for touch panel of mobile phone because it will have ripple of pressing. IPS(In-Plane Switching)-- With advantages of wide visual angle and good performance of color reduction. CPA(Continuous Pinwheel Alignment)--...

The DIY option works for many different kinds of phone problem, although some are beyond the skill of the average layperson. Here is a guide to some of the most common problems and basic advice on fixing them. Shattered Screen The touchscreen of a smartphone consists of three different layers: a glass layer and a digitiser, which are always stuck together, and an LCD screen, which is separate. One of the most common problems is when the glass screen shatters. This is possible for even inexperienced phone owners to replace, although it is a fiddly job and may take up to two hours. It's possible to tell whether it's just the glass that's broken or the LCD too, because if it's just the glass the phone will still work, but if it's the LCD, it won't. Replacing the LCD is not normally something that can be done by an amateur. Water damage Getting the phone splashed or - worse - submerged in water is...

Screwdrivers A good mobile phone repair kit will contain a selection of different screwdrivers of different types and sizes. Most mobile phone screws are either 'Phillips' (that is their head is a cross-shape) or 'Pentalobe' (for which the head is a five-pointed star). If the kit is required for a particular model of phone, then it's a good idea to research the kind of screws it contains before getting a kit to ensure the correct screwdrivers are included. One useful feature on the more expensive screwdrivers is a built-in light. This can make it much easier to see inside the phone. Opening Tool There are lots of tools available specifically designed for opening mobile phones. It's not a good idea to use any kind of metal implement for this purpose (for example, don't be tempted to use a screwdriver), so most of them are made out of some form of plastic. One popular design is the shape of a guitar plectrum, but others are more stick-like. It...

Liquid optically clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. Primary advantages of LOCA compared to other adhesives are its: ·Re-workablility ·Adhesion to non-even surfaces ·Superior optical properties ·Durability LOCA follows traditional die-cut film adhesives, also known as optically clear adhesives (OCA tape). LOCA also allows for thinner designs and new technologies, such as the use of silicone, improve the properties of the final product. Feature: 1. Peeling caused by outgas from plastic is restrained. 2. Heat and humidity resistance (prevents haze increase). 3. Excellent adhesion to difficult-to-adhesive surface (such as hard coated surface). 4. Gap-filling ability to fill the printing gap.

TFT stands for "thin-film transistor." LCD stands for "liquid crystal display." Both terms refer to the flat-panel display, or screen, of a computer monitor or television set. TFT v. LCD LCD is a generic term. A TFT display is one kind of LCD. Differences TFT displays are made using large sheets of transistors, each one of which is controlled independently. A TFT screen is an "active-matrix" screen where each pixel of the display is illuminated individually. Sharpness and Speed A TFT display is sharper and brighter than a common LCD display. It refreshes more quickly than a regular LCD display and shows motion more smoothly. Power Usage TFT displays use more electricity than regular LCD screens, so they not only cost more in the first place, but they are also more expensive to operate. Conclusion A TFT display is much higher quality than a regular LCD display. It is a better display in every way, except that it is more ex...
