METHOD AND APPARATUS FOR BATTERY GAGING IN A PORTABLE TERMINAL USING AMOLED DISPLAY

摘要

PURPOSE: a kind of portable terminal of battery gauge method and apparatus includes that displayer provides, and includes control device to accurately carry out battery gauge using ADC, without individual batter metering device. ;CONSTITUTION: the voltage of control unit measurement battery determines the buffering frame buffer (S202) of image data at predetermined amount of time (S201), and has determined RGB information by the image data (S203) of pixel. Control unit calculates the corrected values (S205) that backup corrected value passes through all each pixels of backup that add up corresponding to the RGB information calculating correction of a final proof value of each pixel (S204). Control unit determines that correction corresponds to correction of a final proof value (S206) and determines that the surplus of battery passes through the voltage measured and battery and confirmation correction voltage (S207) of summing. Control unit notifies corresponding information, judges that residual capacity of battery gives user (S208). ;The 2013 of copyright KIPO submissions;[Reference numerals] (AA) starts; (BB) terminate; (S201) for measuring the battery of voltage; (S202) frame buffer of caching image data is determined; (S203) determine that RGB information determines the image data of each pixel; (S204) determine that backup corrected value corresponds to RGB information to each pixel; (S205) it calculates correction of a final proof value and passes through all backup corrected value pixels that add up; (S206) confirmation correction voltage value corresponds to correction of a final proof value; (S207) determine that the battery of dump power passes through the measured voltage value of summation and above-mentioned correction voltage value; (S208) information is notified to correspond to the dump power of battery
