Has the cathode ray tube fi nally earned the right to a comfy retirement? In the world of computers the answer is pretty much yes. Except for economy machines, or high end machines for graphics artists, new computers mostly come with liquid crystal displays. As the price of LCDs drops, its v i c - tory is l i k e l y to be complete. But video is another matter. Though most computer users favor brightness and (apparent) sharpness over all else, owners of home theatre systems are looking for much more. And new technologies — some already here and others on the horizon — will make the home theatre experience much more like watching a “real” movie. The cathode ray tube is a diffi cult act to follow, though. The CRT: still alive? It’s a vacuum tube, of course, one of the very last ones to survive in massmarket consumer products. It still works very well because it is a mature technology. The CRT has been refi ned to the point where it has been able to fend off a number of competitors. And fi rst in its list of advantages is price. Price is important, because TV sets have become a commodity. What we mean is that the choice is dictated far more by price and (to a lesser extent) features than by great technological advantages. However, the CRT has more than mere low cost to offer. Future Screens The most important of these is the range of brightness it can offer. If it were an audio component, we would call it dynamic range. A CRT can be very bright, but it must get very bright before it overloads and treats all brightness values the same. Of course the tube itself is not the only factor determining the range of tones, but at its best it can make more expensive d isplay s look washed out. A l o n g with the wide brightness range comes a vast range of colors, and it’s easy to see why. If a display doesn’t wash out in the bright scenes and doesn’t get murky in dark scenes, it can present a wider gamut of colors. That means a CRT-equipped TV set has less need to “translate” a color it can’t reproduce into one within its range. We don’t want to overstate this point, because no display can come close to matching the range of colors visible to the human eye…or even to photographic fi lm. If the CRT is so good, why would we want to replace it? Unfortunately the CRT also has a long list of drawbacks. The tube is large, and especially deep, it is fragile, it is heavy, and — like other vacuum tubes — it eats up energy. It is ill-suited to TV sets bigger than 36 inches (measured diagonally, about 91 cm). It is also Can you buy the perfect video screen? Perhaps not yet… ill-suited to the widescreen sets that are now the norm in home theatre. Let’s see why. A CRT is a big glass bottle, with an emitter of electrons in the “neck” at the rear. The face is coated with colored phosphor dots which glow when an electron beam strikes them. A complex set of magnetic control devices sweeps the electron beam across the face, making the appropriate dots glow to make up the image. The illustration shows an early CRT, with a neck much longer than the width of the screen. Those early CRTs were round, to avoid light falloff in the corners, and even many modern CRTs have rather rounded corners. As manufacturers began making larger screens (a 21” tube used to be the “big screen” norm), they were reluctant to increase the tube depth in proportion. The short-neck tube was born, and as tubes got even wider, the necks got proportionately shorter yet. The modern CRT is likely to be something like this. Notice that the electron beam going to the extreme edge of the screen is traveling a lot farther than the one ULTRA HIGH FIDELITY Magazine 19 Cinema
