OLED Displays and the Immersive Experience

Matching Techniques Ride to Rescue OLED Displays

Combinatorial optimization problems have recently emerged in the design of controllers for OLED displays. The objective is to decompose an image into subframes minimizing the addressing time and thereby also the amplitude of the electrical current through the diodes, which has a direct impact on the lifetime of such a display. To this end, we model this problem as an integer linear program. Sub...

Novel Electron-Transport Materials for OLED TVs and OLED Mobile Displays

With the market for mobile AMOLED displays still increasing, both Samsung Mobile Display and LG Display have announced that OLED TVs will be commercially available in 2012. OLED TVs have different requirements compared to mobile devices and especially the lifetime has to be significantly longer in TVs. Therefore, Novaled has developed new ETL materials that lead to much longer lifetime in monoc...

Ambient contrast ratio of LCDs and OLED displays

We systematically analyze the ambient contrast ratio (ACR) of liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays for smartphones, TVs, and public displays. The influencing factors such as display brightness, ambient light illuminance, and surface reflection are investigated in detail. At low ambient light conditions, high static contrast ratio plays a key role for A...

Low Image Distortion Constrained Power Saving for OLED Displays

Organic Light Emitting Diode (OLED) displays have matured into current smartphones. How to prolong the lifetime of displays while preserving the display quality becomes a primary issue. In this paper, we propose a low image distortion constrained power-saving approach for OLED displays based on gamma correction and saturation scaling. We first investigate the impact of gamma correction and satu...
