Grating Light Valve Display Technology

The Cathode Ray Tube TV set has ruled the consumer electronics world for decades. Now a days every one wants big screens for their entertainment rooms. But bigger a CRT screen, the glass tube will be deeper and the set becomes impossibly heavy and unwieldy when the diagonal measurement of the screen goes beyond about 36 inches. Thus the CRT is destined for a slow but sure decline giving way to many new technologies.

All of us must have noted the red colour of the hero's suit in the movie 'spiderman', ....etc

In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, gratings are commonly used in monochromators and spectrometers.

For practical applications, gratings generally have ridges or rulings on their sur ....etc

INTRODUCTION
If you're thinking about assembling a home theatre system, you may be looking at large screen televisions as the heart of your system. Projection TV could give you the size that you want -- CRT screens generally top out at 40 (101 cm) or so, and at that size, they are huge and heavy. Plasma screens can be bigger than that and still manageable, but they can be extremely expensive. Projection TV technology can create large screen sizes at a reasonable price. Or maybe you need to equip a room, like ....etc

In a world of ubiquitous presence of electrons can you imagine any other field displacing it? It may seem peculiar, even absurd, but with the advent of spintronics it is turning into reality.

In our conventional electronic devices we use semi conducting materials for logical operation and magnetic materials for storage, but spintronics uses magnetic materials for both purposes. These spintronic devices are more versatile and faster than the present one. One such device is spin valve transistor.

Spin valve transistor is different from conv ....etc

GLV's basis technology




The GLV device is built on a silicon wafer and consists of parallel rows of highly reflective micro-ribbons ribbons of sizes of a few m with a top layer of aluminium suspended above an air gap that are configured such that alternate ribbons (active ribbons are interlaced with static ribbons) can be dynamically actuated. Individual electrical connections to each active ribbon electrode provide for independent actuation. The ribbons and the substrate are electrically ....etc
