What is the use of the VLCD?(a) Temperature Control(b) Heat Generation

1.	What is the use of the VLCD?(a) Temperature Control(b) Heat Generation(c) Shutting down the LCD(d) Starting up the LCDThis question was posed to me by my school teacher while I was bunking the class.Question is from Nokia 5110 Graphical Display Module in chapter Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» The correct choice is (a) Temperature Control Explanation: The LCD NEEDS a particular OPTIMUM temperature to be able to function properly, so we have the temperature control REGISTERS TC0 and TC1 for that purpose so that the VLCD or the LCD controlling Voltage is regulated to the right temperature for maximum IMAGE contrast on the display MODULE.
