Since cellphone repair community are still upset about the rising price of iPhone LCD screen assembly(no evidence that there will be any drop in the near feature), it won't be a bad choice to know copy iPhone LCDs’features and try some samples to test.
Furthermore, as far as we know, Apple is working on tightening their own supplying chains for after-sale service, OEM parts will be more strictly controlled by Apple. Additionally, since iPhone 5S is going to retire from the market, the OEM screens will disappear in market soon. Facing this situation, repair shops, distributors and suppliers should work together to find out the solution to meet terminal customers' demand. The copy iPhone LCDs will be a good substitute for customers who don't want to pay as much as Apple's official price.
Below are some results we got after comparing 3 main copy iPhone LCDs, including the technology, display, price, cover lens thickness and digitizers' functionality.
As we all know, the digitizer touch screen assembly in most smartphone is assembled by Glass Lens and digitizer touch screen. However, depending on the digitizer touch screen made of different material, such as glass and film, these different LCD screens have different features and performance.
TM LCD Screen
OEM iPhone manufacturers use In-cell technology to make the LCD screens, while 3rd party manufacturers have to choose other economic methods due to cost and risk. TM manufacturer adopt the G+F structure, which build the senor part on a film layer then assemble the film layer with the glass lens to be a whole digitizer touch screen. If you pay more attention to the corners of the LCD screen assembly, you can find out the film edge and rip it apart.
LT LCD Screen
As we mentioned in the previous blog, LT manufacturer use the OGS technology to make the digitizer touch screen. The touch sensor is embedded on the glass lens and the cover lens is made very thin to make sure the digitizer work as good as possible to receive the command from fingers. The LT LCD screen is so thin that we can see the dots and diamond textures beneath the cover lens.
JDF LCD screen
JDF manufacturer use the G+G structure for its LCDs. G+G means glass plus glass. The digitizer touch sensor is made on a glass lens then the glass assembled with the cover lens as a whole digitizer touch screen assembly. Apparently, this kind of structure will increase the thickness of the digitizer touch screen, but it makes it possible that when the screen break, the digitizer screen works as usual. In the opposite, once the LT OGS LCD screen breaks, the whole LCD screen assembly goes bad, and it can't be repaired except replacing the whole part. By the way, the G+F and G+G structures both help prevent the bad situation. The G+G structure also helps light to come across the screen so that we can feel the display more bright and transparent. As far as we know from our supply chain partners, Apple iPhone 7 may use G+G structure on the screen.
