Claim Text:
1. An organic light emitting display device, comprising: a display panel including first to (n)th pixel blocks, each of the first to (n)th pixel blocks having a plurality of pixels and where n>1; first to (n)th current measuring circuits respectively connected to the first to nth pixel blocks, the first to (n)th current measuring circuits to measure driving currents of the pixels in the first to (n)th pixel blocks, respectively; and a timing controller to adjust data signals applied to the pixels based on values measured by the first to (n)th current measuring circuits, wherein a (k)th current measuring circuit among the first to (n)th current measuring circuits is to measure driving currents of the pixels in a (k)th pixel block among the first to (n)th pixel blocks, and is to measure a driving current of at least one overlapped pixel among the pixels in a (k+1)th pixel block that is adjacent to the (k)th pixel block, where 0<k<n.
