Organic LED system applications

Organic LED (OLED) technology promises superior performance in brightness and color resolution, wider viewing angles, lower power consumption, thin displays, and robust physical characteristics. These advantages make OLED displays attractive for next-generation flat panel displays. This paper describes the state-of-the-art in OLED technology and addresses some of the benefits and difficulties facing the integration of OLED devices into a range of imaging equipment applications. We will review OLED performance from a systems perspective and will compare it to OLED material and panel properties. We will also describe the competitive attributes of a flat panel display and recent work done at Kodak on interfacing to OLED devices.

Optical characterization of OLED displays with touch screens

Brightness and color resolution, wider viewing angles, lower power consumption, and a thin aspect ratio are all well understood physical characteristics of organic light emitting diode (OLED) displays, an up-and-coming flat panel displays. Increasing numbers of applications of flat panel displays are being commercialized with touch screens. This paper will describe the optical characteristics of mating a touch screen with a full-color active matrix OLED display. We will quantify the OLED optical properties with respect to touch screens with matte finishes and anti-reflective topcoats, and with and without the use of a polarizer on the OLEDs top glass.
