Prototype 3D flat-panel displays without glasses.

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...

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...

Current Trends of Flat Panel Displays Viewed from Applications

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...

Proposed Diffuse Ambient Contrast Measurement Methods for Flat Panel Displays

Haptic Overlay Device for Flat Panel Touch Displays

In an effort to present users with an increasing amount of information, many industries including automotive and aerospace are adopting flat panel touch displays as a user interface. These interfaces are becoming popular due to their reconfigurability so that control and display functions can be embedded in multiple layers or menus. However, one of the disadvantages of this approach is the need...
