Organic light-emitting diode (OLED)
An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent.
OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs.
A major area of research is the development of white OLED devices for use in solid-state lighting applications.
There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.
An OLED display works without a backlight; thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD).
In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.

I use Plex on the Shield, but I have also tried it in the LG webOS Plex app, as well as Just Player. And it looks the same...

    Best 48” OLED TV for wall mounting in kitchen?

    Just had an extension and kitchen re-design. Looking to wall mount a 48” TV on the wall between 2 windows.

    How important is a warranty to you when buying an OLED tv?

    Considering a larger tv, and seen a few decently LG C2/C3/G2s on eBay and elsewhere at good prices, except they only offer the standard LG 1 year warranty. Some don't have a warranty at all. Obviously you would want to check the TV was working, had a uniform picture, no burn in/lines or...
