Samsung’s Super AMOLED display in the Galaxy S4 has received certification from UL (Underwriters Laboratories — a product compliance tester) for having some of the best colour reproductions on a mobile device. UL said that the display covers 97% of the Adobe RGB colour space which is 30% broader than the sRGB standard. The display has one of the best colour ratios and can be viewed better under sunlight than its competitors thanks to the Diamond Pixel structure.
