Abstract: An organic light-emitting display that includes a substrate comprising a pixel area, a thin film transistor arranged within the pixel area, a wiring electrically connected to the a thin film transistor, an insulating layer covering the thin film transistor and the wiring, a pixel electrode arranged over the insulating layer, a pixel-defining layer having an opening that exposes the pixel electrode, an opposite electrode facing the pixel electrode and an organic emission layer interposed between the pixel electrode and the opposite electrode, the insulating layer having a first region that is overlapped by the pixel electrode and a second region that is not overlapped by the pixel electrode, the second region being thicker than the first region to reduce parasitic capacitance between the opposite electrode and the wiring.

Abstract: A display apparatus includes a power generation unit, a control unit, a source driver, and a display panel. The control unit configured to receive image data, determine a reference grayscale value of the image data, and convert the image data to corrected data according to the reference grayscale value. The power generation unit configured to generate a first pixel driving voltage, a second pixel driving voltage corresponding to the reference grayscale value, and an analog driving voltage corresponding to the reference grayscale value. The source driver configured to generate grayscale voltages by using the analog driving voltage and output, as an image signal, a grayscale voltage corresponding to the corrected data from among the grayscale voltages. The display panel configured to receive the image signal and display an image corresponding to the image signal using the first pixel driving voltage and the second pixel driving voltage.

Abstract: An organic light-emitting display apparatus includes a substrate divided into a display area and a peripheral area that is around the display area. Pixels are formed over the display area. For each pixel, a thin film transistor is provided. An insulation film covers the thin film transistor. Each pixel includes a pixel electrode disposed on the insulation film and electrically connected to the thin film transistor, a pixel defining layer covering an edge area of the pixel electrode, an opposite electrode facing the pixel electrode, and an organic light-emitting layer disposed between the pixel electrode and the opposite electrode. The pixel defining layer includes an opening to expose a center area of the pixel electrode, a first inclination portion, and a second inclination portion. An end of the pixel electrode is disposed between the insulation film and the second inclination portion.
