Depends on light pipe design, LED efficiency*, screen size and brightness. An 8" screen might use nearly twice the power at the same brightness as on a 6" screen.
[* White LEDs are really blue to violet (rarely UV) LEDs with a phosphor or phosphors. The cheapest and least good white ones are actually usually more efficient using a simple yellow phosphor on a blue LED. Some frontlights have also amber LEDs, or even R G B leds instead of "white"]
