Display Device with External Light Source

Low-power flexible organic light-emitting diode display device.

Holographic head-mounted display with RGB light emitting diode light source.

A compact head-mounted holographic three-dimensional display with an RGB light-emitting diode (LED) light source is developed. Issues regarding full-color holographic image design and the quality associated with the use of an LED light source are investigated. The accommodation effect and background noise in the proposed system are discussed based on experimental observation.

High ambient-contrast-ratio display using tandem reflective liquid crystal display and organic light-emitting device.

A high ambient-contrast-ratio (A-CR) and large aperture-ratio display is conceptually demonstrated and experimentally validated by stacking a normally black reflective liquid crystal display (NB-RLCD) and an organic light-emitting device (OLED). Such a tandem device can be switched between the NB-RLCD mode and the OLED mode under bright and dark ambient light, respectively. The normally black c...

Insertion Device Controls at the Swiss Light Source

In the initial phase of the Swiss Light Source (SLS), four insertion devices (ID) will be installed for the first four beamlines. The control system for all the ID’s follows, where possible, a uniform concept to allow a rapid installation schedule, while at the same time allowing for a variety in operational requirements. The components of the control system include the gap drive system with en...

Flexible Display Device with Organic Composite Film

This study presents the fabrication process and display characteristics of a flexible organic polymer display device that consists of a thin substrate of Polyether Sulfone, a multilayer serpentine-type microheater array that is fabricated on the substrate, and a UV-sensitive polydiacetylene (PDA)-polyvinyl alcohol (PVA) composite film. A retention time of one second is achieved with cell sizes ...
