    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.

    Abstract translation: 有机发光显示装置包括具有多个子像素的显示面板; 存储器，被配置为累积和存储由每个子像素显示的数据; 以及面板驱动器，被配置为：基于存储在存储器中的每个子像素的累积数据，计算用于增加或减少每个子像素的亮度的劣化补偿增益值，通过调制输入数据生成每个子像素的调制数据 根据计算出的劣化补偿增益值将每个子像素转换为每个子像素，将调制数据转换为数据电压，并从相应子像素的累积数据累加调制数据，然后将数据存储在存储器中。
