Samsung’s Galaxy S7 and S7 Edge were unveiled last month with significant refinements over their predecessors, making them highly desirable to many consumers. Popular upgrades include an external memory card slot, waterproof construction and one of the finest smartphone displays in the world.
The OLED (organic light emitting diode) displays on the Galaxy S7 and the Galaxy S7 Edge deliver especially vivid colors, sharp images and a high resolution under ambient light, as well as an improved grip and an AOD (Always-On Display) function. Due to all of these features, along with the curved nature of the OLED display panel itself, the Galaxy S7 Edge display is in the spotlight as a trendsetter in particularly innovative and practical display design.
Excellence in Mobile Design: Quad Edge Display
The display that comes on every Galaxy S7 Edge is the world’s first Quad Edge Display. Samsung Display Company created it by adopting special curved display technology that varies the radius for the curvature of the OLED display panel from a 35 radius to a 3.8 radius. This enables the Galaxy S7 Edge to attain extremely fine contours and a more comfortable grip. To make a naturally appearing curved edge, a four-step radius (35R, 9.4R, 5.4R, 3.8R) design process was applied on the left and right edges and also a 25R radius was applied at the top and on the bottom. The four-step process provides smoother curvature for an excellent grip on the sides of the display panel.
Mobile displays are often used under relatively bright ambient lighting, which washes out the image color saturation and contrast, reducing picture quality and making it harder to view the screen. To be usable in high ambient light a display needs a combination of high screen brightness and low screen reflectance.
The picture quality and screen readability of the Galaxy S7 have also been significantly improved with a screen reflectance of just 4.6% and an automatic brightness level up to a highly impressive 855 nits* under high ambient light. That’s about 10 percent higher brightness than its predecessor. So, the Galaxy S7 provides better screen visibility in high ambient light. Further, the Galaxy S7 has a Super Dimming Mode that allows the minimum screen brightness to be set way down to just two nits using a Brightness Slider control. This is ideal for night use or a bedside table, and useful for working quietly without eye strain in dark environments.
Always-On & Power-Savings
What’s more, a new “Always On” Display (AOD) mode will show personalized clock, calendar, status messages, notifications and a variety of other images on the main screen whenever the phone is off (in standby), day and night, while consuming very little power. In fact, because most of the image pixels are black, the AOD feature typically requires only 3 to 5 percent of the maximum display power. Also, the Galaxy S7 Edge is equipped with an Ultra Power Saving Mode that lowers the screen brightness and automatically sets the background to black, both actions further reducing display power and combining to double the battery life. The Always On Display mode uses only 50 to 90 milliwatts.
What do You Think?
Clearly, our finest displays are evolving with greater user functionality, while becoming more visually attractive. Let us know what you think are the best features on the Quad Edge Display and what other features you might like to see on future Samsung displays.

*Definition: A nit is a unit of measurement of luminance, or the intensity of visible light, where one nit is equal to one candela per square meter. Nits are used to describe the brightness of LCD and OLED displays. The higher the number of nits, the brighter the intensity of the visible light.Tags: Galaxy S7, Galaxy S7 Edge, quad edge display, Samsung, Samsung Display
