Abstract:
A method for controlling a display panel includes calculating an on-pixel ratio based on gamma information corresponding to image information, providing maximum current information based on a dimming level, calculating an average current of the display panel based on the on-pixel ratio and the maximum current information, and providing pixel average current information for each of a plurality of pixels in the display panel. The on-pixel ratio is based on the turned-on pixels of the pixels in the display panel. The pixel average current information is determined based on the average current of the display panel.
Abstract:
Provided is an organic light emitting display apparatus. The apparatus may include a substrate including a display region where an image is realized and a non-display region surrounding the display region. The apparatus includes an organic light emitting unit including a first electrode, an intermediate layer, and a second electrode, which are disposed in the display region and are sequentially stacked on the substrate. The apparatus also includes a first inorganic film including a first low temperature viscosity transition (LVT) inorganic material having a first viscosity transition temperature, and covering the organic light emitting unit; and a second inorganic film including a second LVT inorganic material having a second viscosity transition temperature lower than the first viscosity transition temperature, and formed in the non-display region.
Abstract:
A display panel driver includes an adjustment value generation part configured to generate a first adjustment value and/or a second adjustment value based on pre-adjustment luminance values associated with pixels of a display panel, the pixels including a first pixel. The display panel driver further includes an adjustment part configured to receive image data associated with the first pixel for providing a first data signal. The adjustment part may generate the first data signal by adjusting the image data based on the first adjustment value if an input grayscale value associated with the first image data is greater than a reference value. The adjustment part may provide the image data as the first data signal or generate the first data signal by adjusting the image data based on the second adjustment value if the input grayscale value is equal to or less than the reference value.
