Laser Annealing Technique for Next-generation Flat Panel Displays

Development of IGZO TFTs and Their Applications to Next-Generation Flat-Panel Displays

Organic light-emitting devices (OLEDs) have shown superior characteristics and are expected to dominate the nextgeneration flat-panel displays. Active-matrix organic light-emitting diode (AMOLED) displays, however, have stringent demands on the performance of the backplane. In this paper, the development of thin-film transistors (TFTs) based on indium gallium zinc oxide (IGZO) on both Gen 1 and...

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...

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...
