Samsung Reportedly Reached 350 PPI On Super HD Amoled Displays

Currently There are 3 devices utilising the Super HD Amoled displays which are the Galaxy Nexus, Galaxy Note, and the Galaxy S III. However there is one bad thing about this displays, they are pentile displays. Today a korean source reports that Samsung has found a solution to achieve higher pixel densities (350 PPI) on the amoled panels. Currently the amoled panels are  using the pentile matrix pixel arrangement. Futhermore FMM (Fine Metal Mask) production method only allowed for low pixel densities. These results low pixel densities on current generation of amoled panels. It is also reported that Samsung is test-running the Laser-Induced Thermal Imaging (LITI) production method for their amoled panels with very high pixel density. This process allows pixels to be laid out with much greater precision. But apparently LITI is much more cheaper than FMM. The  process couldn't be upscaled for mass production without issues. That's why the report that Samsung has managed to achieve 350ppi pixel densities with FMM for its small and medium AMOLED panels, such as those for smartphones and tablets. If the news is true then Samsung is able to use existing equipment to make these higher PPI displays. The next flagship panel could just be the Super HD Amoled Plus which will take away pentile displays. These newer panels could be in Samsung's next flagship phone and will take away the pentile displays and bring RGB matrix colors as well as higher pixel densities.
