METHOD AND AN APPARATUS FOR A DISPLAY DRIVING BASED ON AN OLED, CAPABLE OF CONTROLLING THE AMOUNT OF CURRENT BY ANALYZING A GRAY LEVEL

摘要

PURPOSE: A method and an apparatus for a display driving based on an OLED are provided to reduce power consumption by controlling a current supplied to an OLED module through analyzing data. ;CONSTITUTION: A display panel includes a plurality of pixels having an organic light-emitting diode. A reference voltage supply unit(160) supplies a reference voltage to the pixels forming the display panel. A data analysis part(200) analyzes image data inputted from outside. A current controller(190) controls the reference voltage according to the analyzed result of the data analysis part. The current controller controls the amount of current which is applied to the pixels.;COPYRIGHT KIPO 2011
