Abstract: An infinitely expandable display apparatus and a driving method thereof are disclosed. An infinitely expandable display apparatus includes a cabinet including a plurality of display units each having an application specific integrated circuit (ASIC) embedded therein, a set board generating a driving command signal needed for driving of the cabinet, and a set interface circuit connecting the set board to the cabinet. The plurality of display units are connected to one another through a unidirectional interface circuit, and at least one of the plurality of display units transfers the driving command signal and an execution result signal based thereon to a neighbor display unit on the basis of a cascading scheme.

Abstract: An organic light emitting display device includes a display panel having a plurality of sub-pixels; a memory configured to accumulate and store data displayed by each sub-pixel; and a panel driver configured to: calculate a degradation compensation gain value for increasing or decreasing a luminance of each sub-pixel based on accumulated data of each sub-pixel stored in the memory, generate modulated data of each sub-pixel by modulating input data to each sub-pixel according to the calculated degradation compensation gain value, convert the modulated data into a data voltage, and accumulate the modulated data from the accumulated data of the corresponding sub-pixel and then store the data in the memory.
