Points out that in cell phones, portable radios, GPS receivers and other portable systems, there is a need to compensate liquid crystal displays (LCDs) against the variation of contrast with temperature. Temperature-controlled crystal oscillator (TCXO), a voltage-controlled crystal oscillator with temperature compensation applied at the voltage control input; Predictable frequency shifts with temperature.
