On the back of the LCD PCB, there are jumpers. What are they used for?

Many types of LCDs such as Character and monochrome graphic contain a PCB. On the PCB are jumper settings that are used to adjust the brightness of a LED backlight through a resistor, or to reverse polarity of a LED backlight and in some cases adjust the contrast of the display.
