With many high-end smartphones adopting 1080p Full HD display nowadays, it is only a matter of time before such a dense screen pixel technology becomes mainstream & common for most phones in the future. Personally, I am contented with 1080p displays for smartphones around 5.5" or less, & I don't think there's a need to further increase the pixel density of screens in the future. Some people have even gone to the extent of suggesting that smartphones will have 4K displays soon, which I think is unnecessary & unrealistic. Hence, I would like to hear the opinions of forumers here & what do you guys think about this. Do you think 1080p displays are sufficient or do you think it should be better? The only possible innovation in smartphone screen technology I can possibly think of is IGZO, within the next year or so, but that's about it. What do you guys think?
