The pixels on OLEDs inevitably lose their brightness over time. The longer an OLED pixel is used (illuminated), the dimmer it will appear next to a lesser-used pixel. [6] In the case of LCDs, the physics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels.
One major challenge for OLED displays is the formation of dark spots due to the ingress of oxygen and moisture, which degrades the organic material over time whether or not the display is powered. [ 131 ] [ 132 ] [ 133 ] In 2016, LG Electronics reported an expected lifetime of 100,000 hours, up from 36,000 hours in 2013. [ 134 ]
For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [40] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.

AMOLED (active-matrix organic light-emitting diode; / ˈæmoʊˌlɛd /) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.
Experimental, possibly virtual reality. Depends on system. Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED. Cancelled and now obsolete technologies are SED and FED.
Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers: Samsung. Sony. Konka. BOE Technology [ 30 ]
OLEDs. Number of employees. 590. Website. j-oled.com. JOLED Inc. (Japanese: 株式会社 JOLED, Kabushiki-gaisha JOLED) is a Japanese display technology company headquartered in Tokyo, Japan, incorporated in 2015 as the result of a consolidation of the OLED business units of Panasonic and Sony. Notable for pioneering an inkjet printing process ...
Thermally activated delayed fluorescence (TADF) is a process through which a molecular species in a non-emitting excited state can incorporate surrounding thermal energy to change states and only then undergo light emission. The TADF process usually involves an excited molecular species in a triplet state, which commonly has a forbidden ...
