Mobile phone full-fit screen technology will become the mainstream

With the popularity of smartphones, the market competition is becoming more and more fierce. Many mobile phone manufacturers hope to highlight themselves through the differentiation of some product characteristics. For example, Apple's early retina screens, vivo's 2K screens and ClearBlack screen technology, etc. These new terms keep appearing, which makes the market competition more intense, but also makes many consumers overwhelmed. Sometimes, while we still do not understand the new technology, another new technology term comes into being. "Full-fit screen" can be said to be one of the hot topics of major mobile phone manufacturers in the past year. So, what characteristics of "Full-fit" technology, and what experience it can bring to users, I believe you are also very concerned about it. So let's take a look at Full-fit screen technology together.

First of all, let's get to know the structure of the screen. The composition of the mobile phone screen can be divided into three parts: protective glass, touch screen and display screen. These three parts need to be fitted. Generally speaking, they need to be fitted twice, once between the protective glass and the touch screen, and the other is between the display screen and the touch screen. According to the way of fit, it can be divided into two kinds: full fit and frame fit.

Frame pasting, also known as word-of-mouth glue bonding, is a simple way to fix the four sides of touch screen and display screen with double-sided glue. This is also the bonding method adopted by most display screens at present. Its advantages are simple technology and low cost. However, because there is an air layer between the display screen and touch screen, the discount of display effect caused by light refraction becomes the biggest defect of frame pasting.

Full gluing technology is to glue the panel and touch screen together seamlessly with water or optical glue. Compared with the box paste, it can provide better display effect.

Another advantage of full-fit technology is that the screen will never gray again. Touch module also increases the strength because of its close combination with the panel. In addition, the fully-fitted screen has a thinner feature than the traditional screen.

At present, the common full-fit screen in the market is mainly the OGS scheme dominated by the original touch screen manufacturer, and OnCell and InCell technology scheme dominated by the panel manufacturer.

OGS is a full-fit scheme adopted by most manufacturers, and it is also the most mainstream full-fit technology at present. OGS technology is to integrate touch screen with protective glass, coat ITO conductive layer on the inside of protective glass, and directly coat and lithography on protective glass. As a result of saving a piece of glass and a single fit, the touch screen can be made thinner and cheaper. At present, the domestic mobile phones using OGS fully-integrated technology are nubiaZ5mini, ZTE GEEK, Huawei Glory 3C and so on. Xiamen Ze Rui
