Abstract
Techniques for implementing and/or operating an electronic device, which includes a display pixel that emits light to facilitate displaying an image during an emission period and a data driver coupled to the display pixel via a data line. The data driver generates a data line voltage signal based on image data that indicates target luminance of the display pixel in the image and supplies the data line voltage signal to the data line during a non-emission period preceding the emission period to facilitate writing the image to the display pixel. Additionally, the data driver supplies an intermediate voltage greater than a ground voltage to the data line during the emission period in which the image is displayed to facilitate reducing luminance variation in the image resulting from a leakage current flowing between an internal node of the display pixel and the data line during the emission period.
