Color and Brightness Screen Uniformity

Panel color uniformity

The thesis behind screen uniformity is how the image is distributed across the screen. A uniform screen displays an image that remains consistent in terms of clarity, color, and brightness at all points across the display area. We test at 50% and 67% brightness levels.

Above, the screen color uniformity (the same colors measured at nine different parts of the screen). This is an attractive result. 

Panel Luminance uniformity

A screen can be a non-uniform screen. On an all-white background, such a screen has a somewhat dirty appearance, with things like banding visible. However, as bad as this sounds it may not noticeably affect the image when looking at colored content like your desktop and/or gaming.

Panel luminance or brightness uniformity tells us how well the screen is lit up by the LEDs and where it is brighter compared to other spots. We measure at nine hotspots on the screen, with slightly varying results. Things are very consistent despite what you might think about the percentage values. For any result in this chapter, a value of under 20% is not noticeable to the untrained eye. Excellent results, albeit with OLED, we expected margins to be even smaller as the lower right side of the panel is deviating slightly.
