DisplayMate: OLED Display on Galaxy S9 Takes Best Smartphone Display Title from iPhone X
March 05, 2018
Dr. Ray Soneira gave the best display title to the S9, which replaced the iPhone X, which replaced the Note 8, which replaced the S8… You get it. Each time Samsung produces a new OLED display, they improve it. To get the entire report see:
What we concentrate on is the power consumption. Ray said, “Since 2013 the Display Power Efficiency of the Galaxy series of Smartphones has improved by a very impressive 60%. The Galaxy S9 has approximately the same high Display Power Efficiency as the Galaxy S8 and Galaxy Note8.” LCDs do have some power consumption advantages for primarily white images
OLEDs are more power efficient for typical mixed image content because their power varies with the Average Picture Level (average Brightness) of the image content over the entire screen.
Ray also indicated that “the Galaxy S9 has 4 user adjustable Performance Modes and 3 adjustable Power Saving Modes that reduce the Display Power by lowering the screen Brightness and setting the background to Black, which can significantly reduce display power and more than double the running time on battery.
What is the point? The last time Samsung changed material was for the S8, We use power consumption as a proxy for determining whether Samsung is using new phosphorescent compounds. If the power consumption does not change than its likely that red and green for the S8, Note 8, S9 and probably the Note 9 are all subject to the same volume discount, which means that if Samsung uses the same amount of material in 2018 as it did in 2017, UDC would see lower material revenues.
