Objects that emit light are usually referred to as incandescent.
Atoms emit energy as light when electrons move to a lower energy level
light and heat
they emit heat when their is a recombination of electron and holes

OLED TV technology works on the self emission of the pixel itself. Every individual pixel can emit light by itself so there is no need for a separate back light.
OLED: Organic Light Emitting Diode.
OLED (Organic Light Emitting Diodes) is a flat display technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. Because OLEDs produce (emit) light they do not require a backlight. This means that OLEDs can be made very thin and very power efficient when compared to LCD (which do require a white backlight).
Oled TVs use Organic light-emitting diodes. They are supposed to be crystal clear.
An OLED screen is typically used in televisions that use a high definition display. The OLED light is what gives the high definition televisions a clear high definition picture.
OLED stands for organic light emitting diode. Like conventional LEDs, OLEDs emit light in a very controlled fashion. OLED technology allows high a density of LEDs to be produced and is likely to become a very common technology for television in the coming years. LCD televisions use a static light behind the LCD panel. The light remains on all the time and LCD shutters open and close to control the amount of light that is passed through. OLED displays do not use a separate light source as each LED emits light as required. Every pixel requires a red, green and blue LED which between them can produce any color at any brightness. Note: Many televisions are advertised as LED televisions. With a very few exceptions, the LED refers to the illumination, with LEDs replacing cold cathode tubes as the light source. The active display technology is still LCD so these are not true LED televisions in the way that OLED displays are.
Light bulbs emit light.
Technetium doesn't emit light.
Yes galaxies emit light
bulbs emit light
The Earth does not emit light, it like the moon reflects light
OLED is organic light emitting diode they let out less light then a typical LED tv which i believe is designed to save you more money buy not having to produce as much light
