Embodiment Construction

[0046] Exemplary embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown.

[0047] It will be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions , layer and / or section should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the spirit and scope of the inventive concept.

[0048] In addition, it will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or one or more intervening layers m...

Abstract

Disclosed are an organic light emitting display device and a method for driving the same. The organic light emitting display device including a display panel including a plurality of scan lines, first through (M)th data lines crossing the scan lines, and a plurality of pixels, where M is an integer greater than 1, a scan driver configured to provide scan signals to the pixels through the plurality of scan lines, a data driver configured to provide data signals to the pixels through the first through (M)th data lines, and a porch data generator configured to generate porch data based on an average value of at least a portion of frame data, and to provide the porch data to the data driver, wherein the data driver is configured to generate the data signals based on the porch data during a porch period, and to generate the data signals based on the frame data during an active period.

Description

technical field [0001] Aspects of embodiments of the inventive concepts relate to display devices. More particularly, aspects of embodiments of the inventive concepts relate to organic light emitting display devices and methods for driving the organic light emitting display devices. Background technique [0002] An organic light emitting diode (OLED) comprises an organic emissive layer between two electrodes, an anode and a cathode. Positive holes from the anode combine with electrons from the cathode in the organic emissive layer between the anode and cathode to emit light. OLEDs have various advantages such as wide viewing angles, fast response speed, relatively thin thickness, and low power consumption. [0003] An organic light emitting display device includes a display panel and a driver. The display panel includes multiple scan lines, multiple data lines and multiple pixels. The drivers include a scan driver supplying scan signals to the scan lines and a data drive...
