DEVICE FOR COMPENSATING FOR BATTERY POWER FOR COLORS AND A METHOD THEREOF BY USING A LIQUID CRYSTAL DISPLAY INTEGRATED CIRCUIT INCLUDED IN A PORTABLE TERMINAL

摘要

PURPOSE: A device for compensating for battery power in a portable terminal and a method thereof are provided to compensate battery power for colors without using a dedicated gauge integrated circuit.;CONSTITUTION: A display unit(105) includes an AMOLED(Active Matrix Organic Light-Emitting Diode) displaying an image. The display unit calculates the color rate of the image. A battery(109) outputs a current battery voltage value in a predetermined period. When the image is displayed, a control unit(101) receives the current battery voltage value and the color rate of the image. The control unit compensates the battery voltage value by using the color rate of the image and the voltage value of the current battery. The control unit changes a battery remaining capacity icon indicating the battery remaining capacity according to the compensated battery voltage value.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Control unit; (103) Power management unit; (105) Display unit; (107) Key input unit; (109) Battery; (111) Memory unit; (113) RF unit; (115) Data processing unit; (117) Audio processing unit
