OLED
A self-emissive display in which each pixel produces its own light and can switch fully off, giving perfect black and per-pixel contrast.
In an OLED panel each pixel is an organic light-emitting diode that makes its own light. With no backlight to leak, a black pixel is truly off and there is no blooming. Response is near instant and contrast holds from wide viewing angles.
In a dark room it behaves like a good projector but with far higher peak brightness, so HDR highlights strike hard against real black. The trade-offs are lower full-screen brightness than a bright LCD and some risk of image retention from static content.
Peak brightness on small highlights runs several hundred to over 1,000 nits, while full-screen white is limited to roughly 150 to 300 nits by power management. Vary content and use the built-in pixel refresh routines, and permanent burn-in is rare in normal use.
