The best type of backlights to make brighter are LEDs since they are DC driven.

A few ways to make them brighrer.

1. increase current. The down side to this is that they burn out sooner.
2. Use PWM to make them brighter without effecting their half-life
3. Use a transmissive polarizer instead of a transfleive. No extra current is needed, but the display cannot be read when the backlight is off.
