Abstract:
1. A memory managing method for display data of a light emitting display device, wherein a plurality of pixels each includes at least two sub-pixels for emitting different color light, each of a plurality of fields is divided into a plurality of subfields including a first subfield and a second subfield, at least two data signals corresponding to sub-pixels for emitting the same color light are time-divided and are applied to a data line in the fields having the plurality of subfields, and selecting signals are sequentially applied to each of a plurality of scan lines in the first subfield and are then sequentially applied to each of the plurality of scan lines in the second subfield, the method comprising: a) dividing the display data of a display image into data for the first and second subfields, wherein for each of the plurality of fields, data for the first subfield is applied to only some of the sub-pixels and data for the second subfield is applied to the sub-pixels to which data for the first subfield was not applied, and the display data includes data corresponding to the at least two data signals; b) arranging the data for the first and second subfields according to a sequence of light-emitting driving; and c) storing the arranged data as pixel-based data.
