Welcome to TuFang Store-Mobile Phone AccessoriesScreenThe phone screen, also called the display screen, is used to display images and colors. The screen size is calculated according to the diagonal of the screen, usually in inches (inch), which refers to the length of the diagonal of the screen. With the increasing popularity of mobile phone color screens, the material of mobile phone screens is becoming more and more important.The color screens of mobile phones vary due to different LCD quality and R & D technology, and their types are roughly TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture are richer.
According to the material of the screen, the current mainstream screens of smartphones can be divided into two categories, one is LCD (short for Liquid Crystal Display), that is, liquid crystal displays, such as TFT and SLCD screens; the other is OLED (Organic Abbreviation for Light-Emitting Diode) is organic light-emitting diodes, such as AMOLED series screens. The most fundamental difference between LCD and OLED is that OLED is self-luminous, while LCD needs to be illuminated by a backlight to display.According to the display technology of the screen, it can be divided into two categories: Passive Matrix and Active Matrix. The difference between a passive matrix and an active matrix is ​​how the current is driven. When the external current passes, the arrangement of the liquid crystal will change. After the current stops, if the arrangement of the liquid crystal does not return to its original position (with memory), it is called an active matrix; and once the current disappears, it will return to its original position and must be restored again. A matrix that can be arranged only by charging is called a passive matrix.
1. Embedded touch technologyWith the gradual improvement of users' requirements for the visual effect of mobile phone screens and the continuous extension of the product lines of touch and display companies, the development trend of full-fit touch display integration is obvious, and touch manufacturers such as Chenhong, Shenghua and Dahong are actively The layout of OGS, LG, Samsung, Sharp and other leading panel companies are accelerating the application of on/in-cell technology. Among them, the in-cell bonding technology is difficult to process and the cost is relatively high. It is still mainly used in high-end models. However, as traditional OGS, on-cell screen technology and production efficiency reach a bottleneck, in-cell technology will It is increasingly favored by mobile phone manufacturers, and the market is expected to be further expanded in the future. In 2016, nearly 50% of the global mobile phones used on/in-cell touch panels, and it is expected to increase to 62.5% by 2020.
2. OLED display technologyOLED is the most promising new display technology after CRT (cathode ray tube) and FPD (flat panel display). It has the advantages of ultra-thin, high brightness, large viewing angle, low power consumption, high Consumers have new demands for products with wide viewing angle, thinness, softness, and high color saturation, among which AMOLED is the most widely used. At present, Samsung, Gionee, ZTE and other brand manufacturers have released flagship models equipped with AMOLED screens. In the future, with the mass production of domestic AMOLED screens, the popularization of AMOLED screens will be accelerated.
3. 3D glass3D glass adopts curved design, which meets ergonomic requirements, and has the characteristics of strong heat dissipation, good elasticity, and not easy to break. Especially using 3D glass as the backplane of mobile phones can effectively solve the problem of shielding radio signals from traditional metal mobile phone cases. , and then provide the possibility for wireless charging and high-bandwidth, high-speed next-generation mobile communication technology applications, which have received extensive attention from mobile phone manufacturers in recent years. At present, many high-end models such as GALAXY S6edge, GALAXY S7, vivoXplay5 are equipped with 3D glass cover. Brand manufacturers such as Huawei and OPPO plan to develop 3D glass applications. In the future, 3D glass may usher in a period of rapid development.
4. Application of sapphire materialThe sapphire material has high hardness and high dielectric constant, and the glass cover made of it has the characteristics of good thermal conductivity, scratch resistance, sensitive fingerprint recognition, and beautiful appearance. At present, companies such as Lens Technology and Zhaoyuan have achieved mass production of sapphire mobile phone covers, which are widely used in electronic consumer fields such as smartphones and wearable devices. Huawei P7, vivoX5L, Gionee Tianjian W808 and other flagship models have been adopted sapphire screen. In the future, as the sapphire manufacturing process becomes more and more mature and the production cost continues to drop, the sapphire screen will accelerate its popularization.
