12 touch screen displays.The full English name is Cover Glass Film Film . This is a bad technology that has been used. It is only a technology between full lamination and non-full lamination. Although the name is GFF full lamination technology, if it is more true In the strict sense, it is not a full-fit technology at all. GFF technology uses surface glass to bond the touch screen and ITO conductive film X , then touch screen and ITO conductive film Y , and then to the LCD layer, a total of 5 layers. Xiaomi 2s and Xiaomi 3 do use OGS full lamination, while Redmi , Xiaomi 2a and Redmi note use GFF full lamination. This technology has low cost and high yield, and is mostly used in low-end cottages. The gap between GFF technology and OGS technology can be seen at a glance. Take the most intuitive analogy. When youmanipulate the GFF screen , you will find that the screen display layer will be darker than the color using OGS technology. It is not so natural, and there is no OGS.The patterns and icons on the screen are like the tentacles that can be felt on the screen, and the middle is separated by glass like the non-full-fitting type ( ps : a 5- layer screen is better than a 2- layer screen OK, everyone understands).
