Mobile phone screen materials


If there is no Apple iPhone 4, IPS screen in the phone is not expected to be so high attention, Hitachi led a display technology, LCD is a wide-angle technology, in the current home appliance market is very well-known, can effectively improve the chromatic aberration and enhance the visual angle, and Apple iPhone4 will IPS and Retina fused together, improve the iPhone 4x960 screen resolution of the current mobile phone, which is not the highest resolution of the iPhone 4x960 pixels. The Apple iPhone 4 has a sleek and slim look, a 9.3mm body thickness is the thinnest smartphone available, it has a 3.5-inch IPS touchscreen, supports multi-touch, achieves a stunning 640x960 pixel resolution, displays finely tuned and finely tuned, and features a powerful new iPhone 4x4 smartphone.


SLCD full name is Splice Liquid Crystal Display, that is, splicing dedicated LCD screen, LCD is a high-end derivative of the variety, its screen performance in warm tones, with high contrast, high color reproduction and other characteristics, and SLCD is the most significant feature of its service life, 50,000 hours of service life for a mobile phone, with a 15 years of LED screen is not a problem, but not used as the average outdoor power SLTC LCD is used as a mobile phone. The price cut of a few hundred yuan is a bit of a consolation, though. The HTC Desire features a 3.7-inch capacitive touchscreen with a high resolution of 480x800 pixels, a stunning display, a touch-sensitive touch, and a powerful third-party operating system, Android OS v2.1s, and an expansive 1GHz microprocessor. Built-in a 5 megapixel camera, support for autofocus and dual LED flash, imaging quality is also very good, no problem with daily on-camera, and Bluetooth, WIFI, GPS and other commonly used features are also supported, the performance is very comprehensive.


ASV full name is Advance Super View, is also a very good screen, one of the most well-known Sharp, through Sharp ASV technology can increase the screen brightness, perspective and contrast, we often see the Sharp ASV screen is in fact the use of Sharp ASV technology CPA panel, but subject to Sharp's patents and monopoly, ASV screen is almost all used as a phantom phone display M930. Yes, Sharp has become synonymous with high quality screens thanks to its technological advantages on LCD panels. Sharp's ASV screen display technology is well known on mobile phone screens. Sharp's ASV technology is not a panel type, but a technique used to improve image quality. ASV technology is mainly used to reduce the overall brightness of the LCD panel and increase the contrast between the particles on the LCD panel. This gives us a clear, translucent display. Cellphones with ASV technology are mostly larger than 3.0-inch screens, but many of the products currently on the market do not support touch. It looks a bit dated now. But the excellent screen display still attracts a lot of friends.


Textured screens came into view in 2009. The phones from Samsung's made screens are also stunning. So what's the mystery of SuperAMOLED screens? SuperAMOLED (Super Active Matrix / Organic Light Emitting Diode) is known as the Magic Arena, a more sensitive display than the traditional AMO-controlled layers, and eliminates the need for touch-sensitive displays. At the same time, SuperAMOLED is equipped with mDNIe (mobile digital natural image engine) technology that can be viewed from any angle and react quickly. Pure black does not emit light, which makes these screens extremely high in contrast and of course more energy-efficient and power-saving. Simply put, Magic Huan is an upgrade to AMOLED, and today's touch-enabled phones are still very attractive to consumers.


AMOLED is a derivative of OLED, compared to the traditional TFT screen, AMOLED has a fast reaction, higher contrast, wide viewing angle and other characteristics, and as a touch screen, AMOLED display its excellent touch performance, whether precision or reaction speed, are higher than the ordinary screen, power consumption is far higher than the ordinary screen, but the AMOLED screen is the most intuitive, so the screen is equipped with LED screen is the most expensive to the screen, the screen is the price is not high. What are the characteristics of AMOLED screens? AMOLED (Active Matrix / Organic Light Emitting Diode) is an active matrix organic light-emitting diode panel. Compared to traditional LCD panels, AMOLED has the characteristics of faster response speed, higher contrast and wider viewing angle. As just mentioned above, AMOLED screens in the display of black, so that the visual effect is greatly improved. AMOLED screen in the mobile phone, so that the mobile phone can get a very realistic display effect, let people see the real things on the phone to restore the possibility, of course, in the era of large screen to make the phone more power-saving is the significance of this screen after the launch of the Nokia N8 is the straight-panel full-touch design, 12.9 mm body thickness of the Nokia touch screen is currently the most delicate display of a mobile phone resolution of 360x3.5 pixels, the front screen is very clear. It features a new Symbian ^ 3 operating system, a 680MHz processor and 512MB ROM + 256MB RAM of body memory. On the back of the aircraft is a Carl Zeiss certified 12MP camera with a powerful image quality comparable to that of a card digital camera, as well as a full range of Bluetooth and WIFI functions.

CBD(Clear Black Display)

CBD Screen Display is an acronym for Claear Black Display. As the name suggests, this technology is designed to make the screen appear darker than black. This greatly improves the contrast of the screen so that we can see the other color areas of the phone screen more clearly. On the other hand, it can prevent other light from interfering with the way you view the screen and is more conducive to screen color reproduction. The application of this technology in mobile phones can greatly improve the display of mobile phones when used in outdoor environments, allowing us to have the best mobile phone display both indoors and outside.The Nokia E7, C7 and C6-01 screens released at Nokia 2010 feature screens with various technologies such as CBD. However, these three phones are not yet on the market and we expect to see several of them in the fourth quarter.


OLED full name is the Organization Light Emitting Display, meaning organic light-emitting diode, it works with the traditional LCD is not the same, it does not need backlight to display the screen, so the material screen is the biggest feature of power saving, in contrast and color reproduction, visual angle is better than ordinary TFT screen, and the back of the Super LED screen is also a high-end OLED OLED OLED mobile phone. OLED screen mobile phones are not many, but in the era of the main TFT screen, this type of screen is still relatively advanced. So what are the characteristics of such screens? OLED, or Organic Light-Emitting Diode, also known as electro-mechanical laser display (Organization Electronic Display), since the beginning of the era of the mobile phone in 2003, the use of this kind of light screen, so that a lot of the device in MP3. The advent of such screens, first of all to make the phone's fuselage can be thinner, a variety of different styles of mobile phones to meet the needs of different consumers. And the reduction in power consumption, so that the phone screen at the same time can have a more reasonable life. OLED screen mobile phone number has been very small, like the early Nokia 8800 series, Nokia N85, N86 screen is gradually used this kind of the stage of LED screen materials in the field of mobile phone OLEDs out of the history. The Nokia N86 is styled with a bidirectional slide cover with a slightly textured metal border around the fuselage. It is equipped with a 2.6-inch OLED display with a resolution of 240x320 pixels at the QVGA level. The system is still equipped with the classic Symbian S60 3rd Edition intelligent operating system, with extensive third-party software resources and a powerful 369Hz processor. A powerful 8-megapixel camera certified by Carl Zeiss is built into the machine, providing excellent imaging, while Bluetooth, WIFI and GPS are also available in a comprehensive range.


TFT screen is currently the most common screen on the market, its full name is Thin Film Transistor, meaning thin-film field-effect transistor, display principle I do not repeat here, it is currently the most widely used in mobile phones screen, color saturation, restore ability and contrast are good, manufacturing process is mature, high output, low price, but the disadvantage is more power consumption, and touch sensitivity is not a great mobile phone. Most of Motorola's handsets feature ordinary TFT screens, from the flagship ME811 down to XT301, and the Motorola XT702 is a licensed version of Motorola Mile Stone, featuring a regular TFT screen, a fiery Android smartphone system and a sideslip full-keyboard styling. The Motorola XT702 is styled with a popular 3.7-inch, full-screen with a sleek, full-screen capacitive touch-sensitive display and a 3.7-inch, full-screen. The system is equipped with Android OS v2.1 intelligent operating system, not only has a wealth of third-party software resources, 550MHz processor frequency and 512MB ROM + 256MB RAM body memory match, performance is relatively strong enough to ensure the operation of the system, software loading speed is very fast.


LCD full name is Liquid Crystal Display, in fact, from a technical point of view, LCD is a TFT screen derivative, the most widely used in mobile phones is the TFT-LCD screen, its most important features are good performance, mass production features, high automation, low cost, and from the overall display effect of mobile phones, LCD than the traditional TFT screen as a number of the main screen applications, but also higher than the screen on the mobile phone screen. LCD screens, which were so popular during the transition from black and white to color, have been replaced by SLCDs, but an LG Optimus 3D reuses the LCD screen and incorporates parallax barrier 3D display technology to create a new 3D-LCD screen that may continue to be used in future bare-eyed 3D phones. LG Optimus 3D uses a straight touch design, equipped with a 4.3-inch 3D-LCD screen, parallax barrier 3D display technology, with a resolution of 480x800 pixels, the machine is equipped with Android OS V2.3 smart operating system, hardware is equipped with a TI OMAP 44XX series dual-core processor, providing two GRAM and bluetooth RAM function of 1125Mb, the main video camera is also capable of 5Mb.

To sum up, seemingly simple mobile phone screen has a lot of distinction, in fact, from the technical point of view of screen evolution, the above eight kinds of screen materials and technology are very close to each other, especially OLED, AMOLED, Super AMOLED These three can be said to be upgraded, upgraded, re-upgraded relationship, and from the overall effect to compare the words, Super AMOLED, ASIAV is the best of the three kinds of the current screen, Super AMOLED ranks first in color brightness, power saving, viewing angle, fineness and so on. Judging from the development trend of mobile phone screen technology, thinner and more power-saving will be the main direction of mobile phone screen development in the future.
