OLED
Organic light-emitting diode display technology in which each pixel emits light independently. It offers high contrast, true blacks, saturated colors, thin panels, and low power consumption, and is widely used in smartphones and wearable devices.
Core Facts
Timeline (last 90 days)
OLED and Mini-LED panels have become widespread in laptops priced above $1,000, and brightness and color gamut are no longer scarce resources.
OLED stands for Organic Light Emitting Diode.
Samsung is the world's largest OLED screen manufacturer and employs strategies such as pixel shifting, automatic brightness reduction, and timeout screen-off to slow burn-in.
The crease problem in foldable screens stems from the slight permanent deformation that occurs in the central area of OLED flexible screens after repeated bending, due to different bending radii.
Each pixel of an OLED screen emits its own light; when a pixel is turned off it emits no light at all and is visually indistinguishable from physical black — this is the technical foundation for implementing Dynamic Island.
Each OLED pixel emits its own light, and when a pixel is turned off the area emits no light at all, making it visually indistinguishable from physical black; LCD requires a backlight module and cannot achieve true pure black.
Apple adopted OLED screens across its flagship models starting with the iPhone X.
The lifespan of blue subpixels in OLED displays is significantly shorter than that of red and green subpixels, so manufacturers such as Samsung make blue subpixels larger (with an area approximately twice that of green subpixels).
The blue light peak wavelength of LCD screens is concentrated in the 430–450 nm range, and the PWM flicker frequency of some OLED panels is as low as 240 Hz
Color e-ink screens have better readability than OLED in strong light because they rely on reflected ambient light rather than self-emission.
