There are only some LEDs, i think. |
Yes, there's a high voltage generator (the inverter) to feed about 2kv to a cold cathode fluorescent lamp, that's basically a tiny neon sign tube...
Laptop computers usually have just one lamp, monitors and TVs usually have two.
LED backlights are used only in smaller LCD screens such as cellphones or digital cameras
