The recent iPhone 7 camera components have been released. From the leaked picture we can find the difference between iPhone 7 and its predecessor. iPhone 7 camera use a kind of flexible cable and it is most likely to equip optical image stabilization system.
Talking about iPhone 6s optical image stabilization feature, this function is used for reducing blur image and providing better performances when in action scenes or in weak light environment. But this module required larger space to accommodate the motion compensation mechanism.
All recent leaks of the "iPhone 7" have shown an optical image stabilization system. The iPhone 7 Plus should actually have a dual-lens camera, though it's unclear what the second lens will do — while it could offer telephoto functions, or simply improve image quality.
Besides the camera, iPhone 7 design is concentrated on faster processors and pressure-sensitive home button, however, and 32 GB of default storage.
It is said that the new iPhone has 3 versions: 4.7”iPhone 7, 5.5” iPhone 7 Plus and 5.5” iPhone 7 Pro. But there is an argument about whether both iPhone 7 Plus and iPhone7 Pro have dual cameras. With the exposure of all videos, people seem to believe the news of 3 versions is true. But recently, some grapevines said only iPhone 7 and iPhone 7 Plus were reserved, and only 5.5”iPhone 7 Plus featured dual cameras.
In all iPhone 7 reports, the elements paid more attention are its outlook design and cameras. From the recently leaked photo, we can find iPhone A10 chip expose with unclear size and it is commonly recognized TSMC Company will monopolize A10 manufacture. As for the details of A10, it will still use dual-core and TSMC technology, and more outstanding in design. It is said that the performance of A10 is 20% better than that of A9. But for its specifications, maybe we will wait to know until the iPhone 7 teardown.
Not long ago, new iPhone 7/7Plus released online with color “navy blue”. This is the innovative color which iPhone has never used.
From this leaked photo, the rumors seem to be true in the design. The three spots on the casing is Smart Connector and it was firstly appeared at 12.9” iPad Pro, which is used for connecting the keypad protective cover. Although there are so many advantages for Smart Connector, it is still not certain whether it will be used in iPhone 7. What’s more, the dual cameras and 3.5mm earphone jack does not appear in this leaked photo, but all of them are still not confirmed and all the truth will be known until new iPhone release.
In the last article I have referred OCA is used for laminate the front glass with other layers when introduced lamination screen. (http://www.dbx.com.cn/NewsDetail/Knowledge-about-Lamination-Screen-You-May-not-Know-136) But what is OCA? OCA is an outstanding bonding macromolecule material which the feature is similar with optical components, and embraces excellent bonding performances. It is used for laminating two or more optical components into optical components to satisfy optical path configuration, or bonding the protective glasses such as optical verniers and filters. The quality and performance of OCA have a great relevance with the image quality and performance of optical instrument. The common adhesive are divided into solid OCA and liquid OCR. OCA is used for the lamination of soft-soft and soft-hard materials while OCR is used for the lamination of hard-hard. The main suppliers of OCA are Nitto and 3M. Famous suppliers of OCR are DuPont and 3M.
OCA is an important source of touch screen lamination. It is a double-sided adhesive tape which is made of acrylics base material with release film on its top and bottom.
1.Strong diaphaneity to improve LCD brightness and reduce energy consumption.
2.Strong adhesion and weather resistance to improve the intensity of touch screen joint face.
3.Water resistant, high-temperature resistant, uvioresistant.
4.Make each layer have a well-distributed space.
5.Avoid xanthation, stripping and denaturing after using for a long time.
The disadvantages of OCA
It will lead to bubbles, winding, uneven joint surface, forbidden re-processing and so on, and will also make automatic processing difficult and bring about low qualified rate.
Main use of OCA
Different OCA will be applied to different areas, but it is mainly used for the lamination of the following assemblings: Electronic Paper, transparent devices, projection screen, aviation optical devices, military optical devices, monitors, lenses, cell phone touch screens in G+F+F technology or F+F technology, touch panels, glasses and polycarbonate materials and so on. Usually we will add up some treatment agent to OCA to improve its optical performance or reduce its shrinkage rate after solidification.
Next time we will introduce something about OCR, please stay tuned!
