L.E.D. Stands for Light Emitting Diode so it is a Diode that makes light...
its to do with circuits,and it flows the electricity to the LEDS
The LEDs are positioned around the edge of the screen and shine behind the LCD layer, providing illumination.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Yes, LEDs are dimmable.
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
No.
red, green, yellow, blue leds
There are several types of LEDs, including standard (through-hole and surface mount) LEDs, which are commonly used for indicators and displays; high-power LEDs, designed for applications like lighting; and RGB LEDs, which can emit multiple colors by combining red, green, and blue light. Additionally, there are specialized LEDs such as organic LEDs (OLEDs) for displays, and ultraviolet (UV) LEDs for applications like sterilization and curing. Each type has unique properties suited to specific applications in electronics, lighting, and displays.
It depend on what the rating voltage of the LEDs are.
SemiLEDS Corporation (LEDS) had its IPO in 2010.
Most modern torches have LEDs in them, several newer models of Audis do too.
Resistors don't light up LEDs. They're required in a circuit along with LEDs in order to prevent excessive current through the LEDs when the LEDs are forward biased. The correct resistance value depends on the supply voltage and the desired (rated) current through the LEDs, and there's typically one resistor in series with each LED.
