    Abstract: Embodiments relate to selectively sensing device characteristics of pixels in a sensing period. Input image displayed on a display panel is analyzed to determine the complexity or gray level difference in different portions of the input image. Based on analysis, the portions of the display panel likely to result in significantly difference in device characteristics are selected with smaller intervals but portions of the display panel likely to experience the same or similar device characteristics are selected with larger intervals. The device characteristics of only the selected pixels are sensed in a sensing period while the remaining pixels are estimated based on the sensed device characteristics.

    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: Disclosed is an organic light emitting diode (OLED) display that includes a display panel including a plurality of gate lines and a plurality of data lines crossing each other to define a plurality of pixels, each pixel including a driving transistor, a switching transistor, an OLED and a storage capacitor; a timing controller that receives pixel data of an input image and timing signals and time-divides a period of one frame into at least a driving sub-frame and a compensation sub-frame based on one or more of the timing signals; and a display panel driver that converts the pixel data into data voltages and supplies the data voltages to the plurality of data lines during the driving sub-frame, and that adjusts compensation gray levels of the plurality of pixels or compensation duties of the plurality of pixels based on a luminance map, which contains information on a luminance deviation for each pixel with respect to a same gray level, during the compensation sub-frame.

    Abstract: A method of compensating for pixel data includes extending a side portion and a corner portion of a real screen to set an virtual screen, setting dimming values of the virtual screen using dimming values of the real screen, calculating an amount of light of each of pixels on the real screen using the dimming values of the virtual screen mapped to a predetermined analysis area, and multiplying the amount of light of each pixel by a gain of each pixel to modulate pixel data.
