Same M9 OLED as Galaxy S10

Samsung Electronics’ Galaxy Note 10 was fitted with the M9 OLED screen, which was the same as the Galaxy S10 revealed in the first of this year.

The South Korean tech giant launched the Note 10 and the Galaxy Note 10+ on Aug. 7, US time. This means there is no big difference in terms of optical specs compared to the previous Note.

Samsung also stuck with the hole-punch “Infinity-O” display, but the latest phones have a single front-facing camera centered in the middle of the status bar area. Samsung said it moved the hole for better vision. The size of the hole was also reduced, to about a quarter the size of the one on the Galaxy S10.

Another difference is the pixel per inch (PPI), which is lower than the Galaxt S10 at around 400. The Galaxy Note 10 features a 6.3-inch (FHD+) display with an assumed definition of 2280X1080. The Note 10+ sports a 6.8-inch display (Quad HD+).

The Galaxy Note 8 and the Galaxy Note 9 each had PPIs of 521 and 516. The PPI for the Galaxy Note 10 Plus is calculated at around 495.

Meanwhile, the red host for the M9 was supplied by Dow Chemical in the US, while the green host was from NSCM, an affiliate of Nippon Steel – company that the South Korean Supreme Court ordered to compensate the South Koreans forced into labor in the past.

The blue host was from South Korea-based SFC, a joint venture in which Japan’s Hodogaya Chemical and Samsung Electronics each held a 54% and 33% stake, respectively.

Hosts facilitate the display’s light emission. The actual light comes from dopants. The red and greed dopants were from US-based UDC, as expected. For blue dopants, Japan’s Idemitsu Kosan was replaced by another Japanese supplier, JNC.

“Samsung Display had been looking to replace Idemitsu Kosan for a while now, due to its resistance to its requests,” said one source close to the matter.

One OLED expert said that JNC managed to reduce the spectrum FWHM by using both Boron and Nitrogen. “The color purity is so high that it’s become possible to express more colors without making the blue waves too deep,” he added.
