<p>PURPOSE: A liquid crystal lens driving apparatus, a terminal device including the same, and a temperature control method thereof are provided to detect the accurate temperature of a liquid crystal lens, thereby maintaining stability of the apparatus. CONSTITUTION: A liquid crystal lens(131) controls a focal distance according to applied voltage. A lens drive part(121) applies voltage to the liquid crystal lens. A sensor drive part(123) detects the temperature of the liquid crystal lens. The sensor drive part compensates the detected temperature. The sensor drive part determines a state of the compensated temperature which is in a predetermined temperature range. A heater drive part(125) controls heat generation of the liquid crystal lens.</p> |
