[ To extend the life of the backlight bulbs , you can use the following method ] :
1 , the luminance of the backlight under the conditions to meet the requirements to reduce the operating voltage , can be greatly extended life.
2 , AC power supply 10 ~ 12V, series 10 Euro to 50 Euro limiting resistor , reducing the impact on the filament boot .
3 , the following figure voltage of 10V renderings
