    Abstract: A special mode processor drives a display panel to display an image. When the display panel is configured to operate in a special operation mode, the special operation mode processor determines a pixel block size for blocking the plurality of pixels into a plurality of pixel blocks and determines a first set of on-pixels and a first set of off-pixels. The first set of on-pixels is initially turned on and the first set of off-pixels is initially turned off. A drive history representative value is generated for the first group of pixels that represents a drive time and drive characteristic for the first group of pixels. The drive history representative value is compared with a threshold value. Responsive to the drive history representative value exceeding the threshold value, a second set of on-pixels and a second set of off-pixels are turned on and off respectively.

    Abstract: An organic light-emitting display device including a display panel, a power supply, a selective driver and a gamma change driver is disclosed. The display panel includes sub-pixels. The power supply is configured to output a drive voltage for driving the sub-pixels. The selective driver is configured to generate a control signal to enable selective drive between first and second driving schemes for a drive transistor in each sub-pixel, wherein the first and second schemes employ saturation and linear regions of the drive voltage curve respectively. The gamma change driver is configured to change a gamma based on the driving scheme selected by the selective driver.
