Method of driving organic light emitting display device

An organic light emitting display device comprising:

• a display panel including a plurality of pixels arranged in ‘n’ horizontal sensing lines, a driving circuit for driving the plurality of pixels, the plurality of pixels arranged in the ‘n’ (n is an integer greater than 3) horizontal sensing lines are divided into a plurality of blocks, and each block has pixels arranged in ‘m’ (m is an integer equal to or greater than 1 and smaller than n) sensing lines;
• a driving circuit to drive the display panel, the driving circuit configured to:
• sense pixels arranged in one sensing line of the ‘m’ sensing lines in one block of the plurality of blocks;
• and
• sense pixels arranged in one sensing line of ‘m’ sensing lines in another block of the plurality of blocks.
