PCs a white backlight or sidelight is required for a homogeneous illumination of the LCD colors. The white LED seems to be a good choice for backlight since it requires less power and space compared to the commonly used CCFL (Cold Cathode Fluorescent Light) backlight. The typical forward voltage of a white LED is in the range of 3V to 5V. Since the best choice to power white LEDs is a constant current source and the input voltage range of a Li-Ion battery is below or equal to the LED forward voltage a new power supply solution is required.
