Mobile phone screen OCA bonding technology will become mainstream
With the Apple iPhone4 interview, the competition in the smart phone market has intensified, and many mobile phone manufacturers hope to highlight themselves through the differentiation of some product features. For example, Apple's early retina screen, BBK's first 2K screen and so on. The constant emergence of these new terms has made the market more competitive, and at the same time, many consumers are overwhelmed. Sometimes we have not understood the new technology, and another new technical term has been born. "Full fit screen" can be said to be one of the hot topics of major mobile phone manufacturers in the past year. What features of "full screen fit" technology, and what experience can be brought to users, I believe everyone also They are very concerned, so let's take a look at the full-fit screen technology.
Let us first understand the structure of the LCD screen. The screen of the mobile phone is divided into three parts, namely the glass cover, the touch screen and the LCD screen. These three parts need to be fitted together. Generally, it requires two fits, one fit between the protective glass and the touch screen, and the other fit between the display screen and the touch screen. According to the way of fitting, it can be divided into two types: full fit and frame stick. The frame sticker is also called double-sided tape, that is, the double-sided tape is used to fix the touch screen and the four sides of the display screen. This is also the bonding method adopted by most displays at present, which has the advantages of simple process and low cost, but because of the display. There is a space layer between the screen and the touch screen, and it is easy to get into the gray in addition to the display effect. The full-fit technology, OCA optical glue, completely closes the glass cover and the LCD screen in a seamless manner. Compared to the frame, it can provide a better display. Another benefit of the full-fit technology is that the screen is no longer worried about getting into the gray. The LCD screen is also lighter and thinner than traditional screens because of its tight integration with the glass cover.
