A luminance control method for OLED burn-in prevention using user information

Abstract

In this paper, we propose a novel luminance control method utilizing user information (UI) to prevent burn-in in organic light emitting diode (OLED) displays. To control the luminance on a burn-in potential region (BPR), we first calculate the visual angle of each pixel on display utilizing UI and design a visual acuity model based on the cortical magnification theory. Next, we generate a UI-based saliency map by combining the visual acuity model and an image saliency map. Finally, the luminance of the BPR is adjusted based on the UI-based saliency map and the local contrast of the BPR. Experimental results show that the proposed method not only controls the luminance of the BPR to a degree of which users barely notice the change but also greatly extends the lifetime of the OLED.
