3 ways, each pixel is made up of 3 LED (Light Emitting Diode) each a different color, red, green, and blue, that is if you were asking in reference to a LED flat panel TV! !
yes, but the light that it will produce is dim
Yes amps from Infinity, Sony and many others have led's built in.
LED spotlights are usually used outdoors. LED spotlights are usually used to light up porches and yards. LED spotlights are also used in Art Galleries to light up showcase displays.
light up when forward biased
LCD displays require an additional light source to light up in the dark. LED displays generate their own light.
Lemons don't usually produce electricity. It would be quite tricky to convert the small amount of energy available in a lemon to electricity. Nor would it be worthwhile; you would probably get a few seconds or minutes of electricity, at most. That is why lemons can produce enough electricity to light a small LED bulb. But a simple experiment can be done by taking a fresh lemon, a small LED bulb and a conducting wire. If you connect the lemon with the wires and the bulb, the bulb will light up for a few mnutes. This happens because lemon which has citric acid helps in electrolysis.
