Screen Brightness and Performance in High Ambient Lighting
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 or read the screen. To be usable in high ambient light a display needs a dual combination of high Screen Brightness and low screen Reflectance – the Galaxy S7 has both. For most image content the Galaxy S7 provides over 440 cd/m2 (Luminance, which is a measure of Brightness sometimes called nits), comparable or higher than most LCD displays in this size class. Its Screen Reflectance is 4.6 percent, close to the lowest that we have ever measured for a smartphone. Our Contrast Rating for High Ambient Light quantitatively measures screen visibility and image contrast under bright Ambient Lighting – the higher the better. As a result of its high Brightness and low Reflectance, the Galaxy S7 has a Contrast Rating for High Ambient Light that ranges from 88 to 118, among the highest that we have ever measured for a smartphone.
Higher Automatic Brightness
More importantly, on the Galaxy S7 the Maximum Brightness can go much higher when Automatic Brightness is turned On, so that users can’t permanently park the Manual Brightness slider to very high values, which would run down the battery quickly. High Screen Brightness is only needed for High Ambient Light, so turning Automatic Brightness On will provide better high ambient light screen visibility and also longer battery running time.
When Automatic Brightness is turned On, the Galaxy S7 produces up to an impressive 855 cd/m2 (nits) in High Ambient Light, where high Brightness is really needed – it is tied with the Galaxy Note 5 for the brightest mobile display that we have ever tested. As a result of its high Brightness and low Reflectance, the Galaxy S7 has a Contrast Rating for High Ambient Light that ranges from 119 to186, also the highest that we have ever measured for a Smartphone display.
