Recently, a user exposed a new Nokia phone called Lumia 825 on his microblog, which is an upgraded product of Lumia 820. It is said that it will be upgraded from the ClearBlack OLED screen to the same PureMotion technology IPS screen as Lumia 920. After the birth of Lumia, Nokia has made great efforts on the screen. What's the difference between these concepts?
First of all, ClearBlack and PureMotion refer to screen display technology, while OLED and IPS refer to screen materials. There is no direct relationship between display technology and screen materials.
ClearBlack technology
ClearBlack refers to "Clear Black Display", or "CBD" for short. It is a technology used to enhance the display effect of the screen outdoors, and is mainly promoted by Nokia. In fact, ClearBlack is just a way to improve the visual image effect by reducing the reflection of screen light, especially the display effect under outdoor light. In this way, users can still use mobile applications normally in the outdoor environment with strong light. In addition, CBD technology can also help improve the visual angle and contrast of the screen, making the screen color display more vivid and the screen looks more bright.
As a screen display enhancement technology, ClearBlack is fundamentally different from the concept of screen materials. For example, NOKIA Lumia 800 uses a screen made of Super AMOLED materials. At the same time, it also applies CBD technology on the screen, which makes the overall display effect further.
The application models of ClearBlack technology include: Nokia C6-01, Nokia N8, Nokia N9, Nokia Lumia 800, etc.
PureMotion technology
PureMotion technology has brought Lumia 920 the most important leap in screen touch experience since the large-scale popularization of capacitive touch screen smart phones in 2007. Nokia combines super sensing technology with the best touch screen, making the Lumia 920's screen sensing ability surpass all other smart phone screens. In winter, you don't need to take off gloves to touch the cold screen, nor put your nose close to the screen to answer the phone. You can wear gloves and operate the screen directly with your fingers. Not only that, you can directly click on the Lumia 920 screen even if you use an ordinary ball point pen or water pen, or have very long nails.
In addition, IPS LCD screen using PureMotion technology provides a higher voltage difference to drive each pixel when the display state changes, thus ensuring a cleaner transition between picture frames. In this way, the screen can stably display 60FPS images.
OLED
OLED， That is organic light-emitting diode. The OLED display mode is different from the traditional LCD display mode. It does not need backlight and has the characteristics of self illumination. It uses a very thin organic material coating and glass substrate. When there is current, these organic materials will emit light. Moreover, OLED display screens can be made lighter and thinner, and OLED technology development has a larger visual angle, and can significantly save power.
Samsung AMOLED screen, the most typical representative of OLED screen, has the following characteristics: high brightness, excellent display effect even in the sun; In addition, the color contrast of this screen is very high, which even causes color deviation. Some users are disgusted with this. This can be said to be an advantage or a disadvantage, but each has its own advantages. At present, the AMOLED screen has roughly developed into three generations: AMOLED Super AMOLED、Super AMOLED Plus。
IPS
IPS screen is commonly known as "Super TFT". IPS screen has the advantages of transparent and bright display effect, large viewing angle, and a viewing angle of nearly 180 °. In practical application, the most typical case of IPS screen is Apple iPhone series, such as iPhone 4S, iPhone 5, etc. It is also Apple's iPhone that has carried forward the application of IPS screen in mobile phones. At present, there are a lot of products using IPS screens in the market, but the quality is also uneven. The display effect of IPS screens from different manufacturers will be different. There is a big difference between domestic screens and large factory screens. Consumers need to choose according to the actual situation when purchasing..
Summary:
Nokia has added many distinctive features and highlights to the new Lumia phone, which can be seen as the core of Nokia's differentiation. With regard to the PureMotion technology of the screen, Nokia has once again opened the gap with its rivals with a humanized design concept, and has good selling points. At present, the flagship model Lumia 920 has been sold, and the market is in good condition. We may wish to continue to look forward to the future performance.
