چکیده

A high-speed column driver IC with an area-efficient high-slew-rate buffer amplifier is proposed for use in a large-sized, high-resolution TFT-LCD panel application. In the architecture, explicit isolation switches have been embedded into resulting fast settling response. The also has structure that adjusts tail current of input stage using very compact adaptive biasing. IC, having driving 55-inch 4K ultra-high-definition (UHD) TV panel, was fabricated 0.18-?m 1.8-V low-voltage, 1.2-?m 9-V medium-voltage, and 1.6-?m 18-V high-voltage CMOS process. performance evaluation results indicated 90% 99.9% falling times were improved from 1.947 µs to 0.710 (63.5% improvement) 4.131 2.406 (41.7% improvement), respectively. They layout size reduced 5580 ?m2 4402 (21.1% reduction).

A Low Power High Speed Class-B Buffer Amplifier for Flat Panel Display Application

A low power, high speed, but with a large input dynamic range and output swing class-B output buffer circuit which is suitable for the flat-panel display application is proposed. The buffer draws little current during static but has a large driving capability during transients. It has been demonstrated with the TSMC 0.6μm CMOS technology.

High-speed temporal characterization and visualization of spatial light modulators and flat-panel displays.

An apparatus that can characterize and visualize temporal dynamics of spatial light modulators (SLM's) and flat-panel displays is constructed and evaluated by use of a commercially available SLM. The apparatus is based on the stroboscopic video sampling method and has a temporal resolution of the order of microseconds, permitting measurement of a long event (>100ms) with a high signal-to-noise ...

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...

Parallel Read-Out High-Speed Input Buffer ATM Switch Architectures

The prototype first in first out (FIFO) input buffer asynchronous transfer mode (ATM) switch is known as the architecture on which the transfer capacity is considerably limited, and is necessary to be given some improvement. In this paper, a novel parallel read-out structure is introduced to the input buffer ATM switch design to remove such the above limitation. Transfer performances of cell tr...
