Ergonomic Aspects of Flat Panel Displays.

Ergonomic aspects of portable personal computers with flat panel displays (PC-FPDs): evaluation of posture, muscle activities, discomfort and performance.

The advent of compact and lightweight portable personal computers has offered its users mobility. Various sizes of PC-FPDs can now be seen in the occupational setting as an alternative to the desktop computers. However, the increasing popularity of this relatively new technology may not be without any accompanying problems. The present study was designed to evaluate the use of PC-FPDs in terms ...

Electromagnetic Eavesdropping Risks of Flat-Panel Displays

Electromagnetic eavesdropping of computer displays – first demonstrated to the general public by van Eck in 1985 – is not restricted to cathode-ray tubes. Modern flat-panel displays can be at least as vulnerable. They are equally driven by repetitive video signals in frequency ranges where even shielded cables leak detectable radio waves into the environment. Nearby eavesdroppers can pick up su...

Current Trends of Flat Panel Displays Viewed from Applications

With the rapid spread of broadband Internet and the improved infrastructure for wireless communication, we have substantially entered into the era of ubiquitous networks. FPDs are quickly gaining importance in this era, as they act as human-information interface and contribute to technological advances beneficial for our lives. The progress in LCD technology is lightning-fast, and LCD has becom...

Edge-Lit Coherent Backlight for Flat-Panel Holographic Displays

Coherent backlight is an essential component for holographic displays. In this paper, a compact design of edge-lit coherent backlight featuring two holographic optical elements for two-dimensional beam expansion is presented. In experiments, the input laser beam is magnified by a factor of 89 with a diffraction efficiency of 4.3%. More importantly, holographic images can be successfully reconst...
