From green and black blocks of liquid crystals , cell phone displays traveled a long path forward, and trying to reach new heights. Super AMOLED,Retina Display,Gorilla Glasses...the list is going on. Which is the best display among that? It is a difficult question to answer .Each one has its own pros and cons.

Super AMOLED or  Super Active Matrix Organic Light Emitting Diode used in PDAs has a major feature. This display has no separate layer to  detects touch. That is touch sensitive layer is integrated to screen. This display is used in Samsung smart phones such as Galaxy S series,Wave, Omnia etc. Super AMOLED display is characterized bye brighter screen,less power consumption and less sunlight reflection.

When we come to Apple iPhone4, you may wonder how much display is improved from iPhone3. iPhone4 make use of display technology namely Retina display.It is characterized by high pixel density, so it is almost impossible to distinguish individual pixels!! In these technology curved edges are more and more smooth compared predecessors. It  also have some catchy characteristics like improved contrast ratio,In Plane Switching (IPS) technology which improve viewing angle and chemically treated glass over the screen which improve the quality of image.

 Another innovation is Gorilla glasses. Actually it is a protection for screen, this glasses are unscratchable and unshatterable. It is already present in wide variety of products from PDA to laptops.We can find it on the devices such as Dell Streak,LG Optimus7 and upcoming Sony Bravia TVs.

This is the present scenario.What about future? Definitely there will be a long list!! Out of which quantum dot display sounds promising. These displays are formed by semiconductor nano crystals and somewhat similar to OLED displays but it has a lot of exciting features.Improved color range, clarity, low power consumption..etc.We can expect iPhone5 or Android4 running on quantum dot display !!!

As tech going green , you may wonder how can be a cell phone become green !! Many manufactures are planing to release their green phones soon. What about having a disposable phone or phone made of wood? Can you imagine mobile phone made of paper?? It is the future of cell phones.

 As number of consumers increases, mobile phones made of plastics and other materials which are not eco-friendly become a threat to nature. That is why the green phone concept becomes more and more important.
Even paper can used to make a phone. Origami phone is a concept phone made of paper,  which can be disposed without threatening environment. 

Another innovation in this field is OLED cell phones. In which the entire phone is filmed in to a cylinder. Main advantage of OLED screen is that which will massively reduce the energy consumption, which can be useful reaching eco-friendliness objective.

You must be familiar about photosynthesis. Green Bracelet cell phone works on this concept. You can wear the phone like a bracelet. That is phone is always exposed to sun light. Phone has solar cells which  charge it.Sounds great ,right? But main draw back is that this phone has only basic features like calling and messaging.

Apart from concept phones it is good to see that a lot of manufactures already came with green phones. Best example is Samsung Reclaim. Reclaim is made of bio degradable plastic made from corn.

Manufactures like Sony Ericsson already going through a program called Green Heart,which will help to bring out eco-friendly phones.The challenge involved here is to build green phones without compromising the quality and fun. Let us hope soon such a future will come.

Finally Nokia is ready to try an operating system other than Symbian. It may come with all new Windows Phone 7 soon.Nokia and Microsoft announced extensive collaboration and the concept Nokia Windows Phone 7 is out. The joining of two technological giants looks promising in the modern smartphone era.
Nokia is struggling to survive with Android and other all new platforms with its Symbian platform. And finally it rethinks to try platfrom other than Symbian to meet the competitive requirements. HTC and Samsung are performing well with Android and Windows platforms recent time. Sony Ericsson has also moved to android. Wait and see what difference Nokia Windows Phone 7 makes!!!
