Biggest Display in the Galaxy

Koreans love competition and particularly, to claim the biggest and the best, (anyone remember the “worlds largest TV” CES wars between Samsung and LG?) Forget all that, Samsung is going for biggest display in the galaxy (ummm Galaxy S20 ultra smartphone that is…) with a new whopping 6.9-inch 3K high resolution OLED display that meets or exceeds twelve (count em, 12) display performance metrics.

Its size is 23% larger than the S10 predecessors and is even larger than the Note10, and claimed to be the largest display (in the Galaxy Note series). Stay tuned for detailed metrics from Dr. Ray Soneira’s latest DisplayMate technology shoot-out.

The Galaxy S20 Ultra’s 6.9 inch diagonal display is called “state-of-the-art” by Soneira. It’s a 3K (3200×1440) resolution OLED, a full curved flexible display mounted on a rigid backplane, that fills the front surface, edge-to-edge of the device. It has a unique front camera O-hole (3.9mm in dia.) at the very top center of the screen (front facing camera and sensors) consuming a mere 0.1% of the display area. The O-hole is implemented as a clear window opening within the OLED display, “…something that cannot be done with LCD technology because of its embedded Liquid Crystal,” Soneira notes.

The display now has the same overall shape as the entire phone, and to get there, Samsung developed a new form factor (taller height to width) aspect ratio of 20 : 9 2.22, making it taller in portrait mode and wider in Landscape mode, making it 25% larger than the 16 : 9 = 1.78 on most Smartphones (and widescreen TVs). Soneira writes, “This provides extra space for Notifications and for displaying multiple apps and content simultaneously on-screen side-by-side.”

Also, Its rounded corners with curves along both edges of the phone display, “…provides two additional user configurable edge screen areas that can be viewed from both the front or the sides, and even when the phone is placed face down. This is particularly helpful for status messages, notifications, memos, an edge clock, and a night clock in the ‘Always On’ display mode.”

But it’s the metrology that make this display shine…

In his DisplayMate Galaxy S20 Ultra OLED Display Technology Shoot-Out, Soneira states:

Based on our extensive Lab Tests and Measurements the Galaxy S20 Ultra has a Very Impressive Excellent Top Tier World Class Smartphone Display with close to Text Book Perfect Calibration Accuracy and Performance that is Visually Indistinguishable From Perfect. Based on our objective Lab Tests and Measurements the Galaxy S20 Ultra receives a DisplayMate Best Smartphone Display Award earning DisplayMate’s highest ever Display Performance Grade of A+ and setting or matching 12 Smartphone Display Performance Records.

Here’s a short list of the top twelve recorded breaking metrics identified in the DisplayMate Shoot-Out:

· Highest Absolute Color Accuracy (0.5 JNCD) – Visually Indistinguishable From Perfect.

· Highest Image Contrast Accuracy and Intensity Scale Accuracy (2.17 Gamma) – Visually Indistinguishable From Perfect.

· Smallest Shift in Color Accuracy and Intensity Scale with the Image Content APL (0.6 JNCD) – Visually Indistinguishable From Perfect.

· Smallest Shift in Image Contrast and Intensity Scale with the Image Content APL (0.03 Gamma) – Visually Indistinguishable From Perfect.

· Smallest Change in Peak Luminance with the Image Content Average Picture Level APL (1 percent) – Visually Indistinguishable From Perfect.

· Highest Full Screen Brightness for OLED Smartphones (828 nits at 100% APL).

· Highest Peak Display Brightness (1,342 nits for Low APL).

· Largest Native Color Gamut (110% DCI-P3 and 139% sRGB / Rec.709).

· Highest Contrast Ratio (Infinite).

· Lowest Screen Reflectance (4.4 percent).

· Highest Contrast Rating in Ambient Light (188 for 100% APL and 305 for Peak Brightness).

· Highest Visible Screen Resolution 3K (3200×1440) – 4K Does Not Appear Visually Sharper on a Smartphone.
