For smartphones, panels in the past two years has been the market speculation hot spots, with 2016 years as an example, from the first half to the end of the beginning, mainly include two major points: a panel is out of stock prices, while the other is the OLED panel. According to the mobile phone online observation, starting from 2016, especially to the early 2017, the "comprehensive screen" concept suddenly caught in the market hot, like airborne generally. So what are the reasons behind it?
On this issue, according to JDI Shanghai Co., Ltd. chairman and general manager Nashikian to the author, in his view, the current comprehensive screen concept of an outbreak of a very important reason lies in the promotion and guidance of JDI, early in October 2016, JDI with large customers to negotiate a comprehensive screen use.
Although the concept of the current comprehensive screen is very hot, but the real use of a comprehensive screen of the smartphone is not much, according to incomplete statistics, there are mainly millet MIX, lg G6, Samsung S8, where xiaomi MIX screen accounted for the ratio of 17:9, while LG G6 screen accounted for 18:9, Samsung S8 is 18.5:9, from the three mobile phone, its screen height compared with the previous 16 improved. This has also led to a message in the market in recent months that 18:9 will be a standard for high-end flagship machines this year. As for the reasons behind it, JDI gives the explanation: "First, 18:9 of the screen accounted for the best time, and secondly, this is the trend."
In addition, according to the mobile phone online, the biggest role of a comprehensive screen phone is to promote the PPI, in the same hand-held handy design, can plug into more display content. In structural design, the overall design of the mobile phone can be more streamlined, through the on-screen UI of virtual tools to replace the cost is not low, the use of a shorter life of the physical capacitance keys.
Although from now on, the emergence of a comprehensive screen is not just needed, but undoubtedly has become the market's new darling, but now the full screen of the smartphone only the above-mentioned several, although some mobile phone brands are claiming to be able to do a comprehensive screen phone, but from today's view is also "Rayson"!
As previously stated, JDI presented its comprehensive screen (full active) concept as early as 2016. Recently, JDI again announced the release of a comprehensive screen (full active), according to its expression, through the "full active" technology to truly achieve a wide range of extremely narrow border screen, and use this technology to develop a smart phone for the 5.5-inch full-HD LCD LCD screen, and has been measured in the second quarter of 2017, and the domestic handset manufacturers, plans to market in the third quarter. So how is this comprehensive screen (full active) implemented? Where is the difficulty?
For these problems, according to JDI simple explanation: "Full active LCD screen through high-density wiring scheme, as well as new processing technology and modular assembly techniques, the most important bottom border to minimize to and the other three sides of the same size." Thus realizing the maximum screen ratio of LCD. ”
And its difficult point is mainly embodied in three aspects: first is the need to achieve a narrow border, followed by the backlight, the third is the actual installation technology; The whole process needs JDI and other LCD panel vendors to develop together. we can see that a comprehensive screen compared with the original screen, mainly in the light import part of the improvement, the use of led to display part of the most rationalization of optical design of the import part of the minimum.
Interestingly, JDI, in addition to releasing full active comprehensive screens, also released full active flex flexible and comprehensive screens, while the three major difficulties in the flexible comprehensive screen are substrate, panel technology and TFT technology.
The reason why it achieves "flexibility" is mainly because its substrate is not the traditional glass, but the use of plastic substrate development, which requires that the plastic material with high temperature resistance, penetration strength, high toughness characteristics! In addition to the high requirements of plastic substrate, it also changed the previous LTPS process to LTOS process, so that the lower problem in the PI substrate to form TFT.
From now on, the adoption of a comprehensive screen will undoubtedly lead to changes in the internal structure of smartphones, the most obvious is the front-mounted camera and fingerprint identification, handset, and so on, to fingerprint identification as an example, it has become the standard of smart phones, smart phone manufacturers once the use of a comprehensive screen, then how to place fingerprint identification is a key, such as Samsung S8 will fingerprint identification after the replacement, of course, if the fingerprint Identification UnderGlass program, Even future UnderDisplay or InDisplay programmes mature, the problem can certainly be solved. Overall, the adoption of a comprehensive screen will lead to a great change in the internal structure of the smartphone, while fingerprint identification and the former camera is only one of the tip of the iceberg!
