Technology always evolving and going cheaper, including the display of smartphone. In late 2012, there are some smartphones with Ful HD display such as HTC Butterfly. The top smartphone manufacturers like Samsung, LG, HTC, and Sony will compete in Full HD smartphone era.
One of the rumored phones to come with Full HD display is LG Optimis G2. The latest rumor says that Optimus G2 will have a 5.5-inch Full HD display, doesn’t like the previous rumor that says the smartphone display is 5.0-inch.
With a size of 5.5-inch, the display pixel density is 400 ppi. Of course it’s lower than HTC Butterfly that has the same resolution but smaller display. The HTC handset has a pixel density of 440 ppi. However it’s very hard to differentiate that pixel density. Human eyes are only optimal for up to 300 ppi.
LG Optimus G2 is estimated to be available in market starting from the first half of 2013.
