Owners of the iPhone 4 and 4S know just how stunning the Retina Display technology can be. Turns out it’s also hard to copy. A recent report says that Samsung is struggling to come up with its own ultra high-resolution solution.
According to Korea IT News, “Samsung Display succeeded in boosting the screen resolution of AMOLED by means of fine metal mask (FMM) technology. In doing so, the display panel manufacturer veered from laser-induced thermal imaging (LITI), an alternative technology it had focused its R&D efforts on. Experts are paying attention to whether the new technique will be able to fully resolve AMOLED’s resolution problem, its weakest point compared with the Retina Display of the iPhone.”
According to industry sources, Samsung has raised the RGB stripe AM OLED resolution up to 350ppi in a lab test by using FMM technology. The 350ppi figure is higher than that of the iPhone 4’s screen which comes in at 326ppi.
FMM technology is used to deposit pixels on a substrate. A metal mask with small grooves is placed on the substrate and then sprayed with an organic substance.
The Patently Apple article also contains some good information on avoiding eyestrain while using a device such as an iPad or a computer screen for long periods of time. It suggests taking frequent breaks away from the screen, sit as far away from the screen as possible, and use glare protectors to reduce the amount of light focused into the eye.
Since a glare protector would defeat the purpose of the Retina Display, the author suggest turning down the brightness of the display when using the iPad for a long period of time.
