Long gone are the days of tiny 3 inch or 3.5 inch displays, even Apple have moved to bigger displays after years of trying to convince everyone that they aren’t needed. Samsung are leading this push to bigger, brighter and higher resolution panels and it looks like it has something special planned for the future. Somewhere in its product mix (probably the Galaxy S4 or maybe the Note 3) Samsung are trying to use a 4.99 inch display with a huge 441 pixel per inch density.  According to my calculations that means an almost 5 inch display with a 1920 x 1080 resolution. Impressive! Well it would be if Samsung could actually mass produce them!

Rumors are continuing to emerge that Samsung is having a hard time perfecting a mass production process for these panels. Samsung Display (SD), another arm of the electronic giant, is responsible for supplying the panels to the smartphone division and it is having some production hiccups. According to industry sources, Samsung Display does not have the technology to mass produce the parts due to issues with its evaporation process technology.

It has already been rumored that Samsung will switch away from AMOLED displays to LCD panels due to production problems. Current speculation is that Samsung is working with 3M to use its LITI technology which will enable OLED materials to be printed more smoothly on glass. But according to insider sources, that process still has problems too!

But clearly the technology exists and I am sure it won’t be long before Samsung work out all the kinks. What do you think about the prospect of a 5 inch full HD display in your next smartphone (when they can be mass produced correctly)?
