Before the introduction, we need to clarify two concepts: “screen material†and “image display technologyâ€, which are two very different concepts. TFT, IPS, SLCD, AMOLED, Super AMOLED, Super AMOLED Plus are screen materials, while ASV, CBD, NOVA, and ReTIna Display actually refer to screen image display technology. Usually these two concepts are more confusing and should be distinguished.
First, ASV technology
The first thing to say is the familiar ASV technology. This is the term that has been frequently mentioned since Meizu M8. Many users simply think that the Meizu M8, M9 and even MX phones use the ASV material screen, but it is not. ASV is called "Advanced Super View" and is a technology developed by Sharp to improve the image display quality, which can increase the brightness, viewing angle and contrast of the screen. It can be seen from this that Meizu actually promotes the concept of “ASV†and does not master the core technology.

In addition, the ASV display technology used in Sharp's original screen is based on the CPA panel, but this display technology may not be based on the CPA panel. At present, some domestic mobile phones use ASV technology, but they do not use CPA panels, and the display effect will be inferior.
Although the use of ASV display technology can improve the screen display effect to a certain extent, but the screen material, resolution and other factors often play a more important role. Take the current mainstream quad-core models (Samsung I9300, HTC One X, Meizu MX quad-core version), thanks to high resolution and advanced screen material, the display effect of Samsung I9300 and HTC One X will be Better than Meizu MX quad-core version. Therefore, ASV technology is not as magical as the legend, it only plays a certain display aid.
Second, CBD technology
The full name of the CBD is "Clear Black Display", which is a technology for outdoor enhanced screen display, which is mainly promoted by Nokia. In fact, CBD technology is not a revolutionary product or technology like AMOLED. It is just a way to improve the visual image effect by reducing the reflection of light from the screen, especially in outdoor light. In this way, the user can still use the mobile phone application normally in an environment with strong outdoor light.
In addition, CBD technology also helps to improve the viewing angle and contrast of the screen, making the screen color display more vivid and the screen look more vivid.
As a kind of screen display enhancement technology, CBD is essentially different from the screen material concept. For example, NOKIA Lumia 800 adopts the screen of Super AMOLED material, and also applies CBD technology to the screen, which makes the overall display effect even further. .

The application models of CBD technology are: Nokia C6-01, Nokia N8, Nokia N9, Nokia Lumia 800 and so on.
