What people use a off black screen for
Off Black is dark enough that a off black screen gives off very little light — on an OLED or AMOLED phone the dim pixels also draw little power, which makes it a good always-on or bedside screen.
Off Black is a muted, low-saturation color, so it makes a calm, distraction-free background for focus, reading or a video call, and it does not cast a strong tint onto faces.
Black screens save power on OLED and AMOLED displays (each black pixel is switched off), reveal backlight bleed and IPS glow on LCDs, and cut glare and eye strain at night. A true-black field is also the go-to background for photography, cinema-style letterboxing, and hiding a screen that has to stay on. Mid-gray fields are the neutral reference for panel-uniformity and colour work.
As a test pattern, a dark off black field is best for spotting backlight bleed and IPS glow on an LCD, or stuck "always-on" pixels on an OLED.

How bright is a off black screen?
A off black screen gives off about 1% of the light of a white screen at the same brightness setting, so it stays very dark — useful when a screen has to stay on without lighting the room. About 33% of its light is blue (a white screen is 33%), which counts as moderate blue light.
What color text is easiest to read on a off black screen?
White text, with a contrast ratio of 17.2:1, which passes the WCAG guideline for normal text. Check any other pairing in the contrast checker.
Does a off black screen save battery?
On phones and laptops with an OLED or AMOLED display, yes — dark pixels use very little power and true black uses none, so a off black screen draws less than a bright one. On a normal LCD the backlight stays on regardless, so the saving is small.
