15.5L: Late‐News Paper: SVGA Full‐Color Bidirectional OLED Microdisplay

This paper describes a new bidirectional OLED microdisplay with an increased SVGA resolution. A bidirectional microdisplay means that the active area comprises of an OLED display with an additional nested image sensor. The paper shows latest results from the labs as well as first results in the field of capturing an eye scene.

14.3: A Novel Concept of a Vein Viewer Based on a Bidirectional OLED Microdisplay

AbstractBidirectional OLED based microdisplays offer interesting possibilities for new applications. A new optical concept of a veins viewer based on bidirectional OLED microdisplay will be presented. The veins viewer records an IR‐image of your veins and this image will be projected in the visible range onto your skin. This enables the visualization of the superficial blood vessels below human skin. Thereby, a simplified and not painful therapy of the patient is possible.

18.3: 3‐D Metrology System based on a Bi‐directional OLED Microdisplay

AbstractBi‐directional OLED based microdisplays offer interesting possibilities for new applications. Light emission and detection is included in one chip by using OLED‐on‐CMOS‐technology. Such device has been primary made for optocouplers or photoelectric barriers, but it offers interesting possibilities for other application fields, e.g. multimedia and metrology. A new optical concept of a 3‐D metrology sensor based on bi‐directional OLED microdisplay will be presented.

Aspects of a head-mounted eye-tracker based on a bidirectional OLED microdisplay

In today's mobile world, small and lightweight information systems are becoming increasingly important. Microdisplays are the base for several near-to-eye display devices. The addition of an integrated image sensor significantly boosts the range of applications. This paper describes the base-building block for these systems: the bidirectional organic light-emitting diode microdisplay. A small and lightweight optic design, an eye-tracking algorithm, and interaction concepts are also presented.

Simulation and System Design of a 3D Metrology Optical System Based on a Bidirectional OLED Microdisplay

Innovative display technologies enable a wide range of different system applications. specifically, in metrology, medical, and automotive applications microdisplays were increasingly used. In the last decades OLED microdisplays were in the focus of display development. A new class of OLED microdisplays with an integrated photodiode array is the latest development. The so-called bi-directional OLED microdisplays combine light-emitting devices (AM-OLED microdisplay) and photo sensitive detectors (photodiode matrix) on one single chip based on OLED-on-CMOS-technology. Currently this kind of display is still a prototype. Based on such a novel bidirectional OLED microdisplay, we present for the first time a system simulation and design of a 3D optical surface metrology system. The first step is the full characterization of the microdisplay. Depending on the characterization results the future system parameters are determined. Based on the characterization results and the application parameters the system design parameters are defined. The functionality of the system is simulated, and a theoretical proof of concept is presented. An example for our application on 3D optical surface metrology system is evaluated.
