Black Screen for Sleep with Ambient Sound
OLED Sleep Mode
Sound: Muted Timer: Continuous (All Night)The Science of Black Screen & Sound Sleep Therapy
Artificial light at night disrupts melatonin synthesis and reduces REM sleep stages. By switching your laptop or phone to an OLED pure black screen, you eliminate optical blue-light emission while the synthesized brown or pink noise masks disruptive ambient traffic, barking dogs, or snoring for uninterrupted sleep.
Everything You Need to Know
Common questions about screen utilities, color temperature, dead pixels, and monitor care.
Why use an OLED black screen for sleep?
Unlike LCD screens that emit glowing background light even on black images, OLED and AMOLED displays completely shut down individual pixels when displaying pure black (#000000). This eliminates 100% of circadian-disrupting blue light, keeping your bedroom completely dark while playing soothing sleep audio.
Does the sound generator require internet streaming or downloads?
No! All soundscapes (White Noise, Pink Noise, Brown Noise, Soft Rain, Ocean Waves, and Midnight Fan) are mathematically synthesized in real time on your device using the browser's Web Audio API. It uses zero data, never buffers, and loops seamlessly all night.
Can I set a timer so it turns off automatically?
Yes. You can select preset sleep timers from 15 minutes up to 10 hours. When the timer expires, the audio gently fades out to save battery and ensure undisturbed deep sleep.
