Effective burn‐in reduction of organic light‐emitting diode display using perceptual color difference between logo and background

The paper proposes a method to delay the burn‐in effect of an organic light‐emitting diode (OLED) display. Usually, the burn‐in occurs in broadcasting company logo regions. In previous studies, logos were compensated by reducing the logo luminance by a specific ratio. This paper proposes a novel logo‐compensation method regarding the perceptual color difference between a logo and background areas. The proposed method has the advantage of being less affected by changes in the surrounding area than the existing compensation method, minimizing the deterioration of the recognition of the logo, and delaying the burn‐in as much as possible. An effective reduction in burn‐in of organic light‐emitting diode (OLED) displays using perceptible color differences between logo and background was investigated. The method has the advantage of being less affected by changes in the environment than the existing compensation method, minimizing logo recognition degradation, and delaying burn‐in as much as possible.
