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 !!!
