Television Technologies

Several types of TV receivers each with upchecks down and controls:

CRT

Cathode Ray Tube is the standard of the older generation grew up watching. It 's like a big light bulb, the screen will end with fluorescent pixels and the other with an "electron gun", which, charged with electricity, emits electrons coated; electrons to illuminate the pixels, the pixels. Old CRT having a curved screen, but more recentThe models are "flat screen TV '- not to be confused with' flat-screen TV", the TV all is fine. Upchecks: It is well known, it is more convenient to buy and repair. CRT design of a very deep black. Down Controls: larger and heavier than others. If you put something in the neighborhood with a large magnet (like a large speaker) can affect the situation.

DLP TV

Digital Light Processing Projection TVs are, shine light through a color wheel on aSemiconductor with small mirrors. The light is reflected through a projection lens onto a large screen. Upchecks: incredibly clear images with clarity seamlessly in any format, brilliant images with dark colors, light weigh, very durable, and the heat, humidity and vibration affected. Down Controls: Available only in the big screen. A flat screen DLP TV, but they need more space than CRTs, because they sit down and require good ventilation to getWall. For a DLP TV wall mounting is not possible and not crisp text. They have a very hot light source lamp needs to cool properly or does not last as long as it should. The viewing angles are not as wide as the other species.

LCD TV

Liquid Crystal Display or LCD televisions have been used as computer monitors. They have small crystals embedded in the screen glow red, green or blue when hit by an electrical charge. By varying the chargevarying the intensity of color and diversity in which charging crystals vary in color. Upchecks: Images can be very strong and very bright. If the unit near a window, LCD TVs are less against the glare. LCD TVs are great for TV wall brackets. Down Controls: LCDs do not just pitch black, and if you want a really big screen, you will not find on a LCD flat screen TV.

Plasma TV

Plasma TVs are like a neon sign is controlled by a computer. Two glass platesMicrobubbles have neon and xenon, with each pixel. If this gas is excited by electric charges, are formed, the distribution of photons, which bring to light the pixels phosphorus. Upchecks: high resolution, a smooth, uniform image across the screen, plasma televisions can display billions of colors for a truly realistic image, a distortion-free wide viewing angle, a plasma TV is also quite lightweight for a wall mount TV. Controls at the bottom: the black levels are just fine ifLeft on the same image for too long, you may experience screen burn, which is to see the image of a permanent 'ghost' is (biggest problem with video games or TV movies), plasma TVs are heavier and more sensitive than LCD TVs of comparable size.

TV Features

Proportions

Two numbers describe how the screen width to screen height applies. Standard screen is 4:3, ie a screen resolution of 480i is 640x480 pixels. Panoramico is 16:9, then a screen 1080th1920x1080 pixels. Go Wide Screen, if you can - you'll thank us later.

Cable or Dish TV

When you subscribe to satellite TV or cable, contact your service provider, you get a satellite dish and decoder to decode the signals.

Subtitling

The text appears at the bottom of the screen to help the hearing impaired - to learn a language useful for those people - it is an integrated feature of most TV and DVD series.

Contrast Ratio

The differencebetween darker and lighter colors in the set can be shown that the higher the ratio, the better the image - 5000:1 is good, 10.000:1 is fabulous; 15,000:1 is good, very expensive!

HDTV compared to HD-ready TV

An HD-ready or HD monitor can not display high definition images when the signal is processed through an external HD tuner, before it goes into the crowd. A true HD television has a factory-installed HDReceiver.

Picture in Picture

A second image appears in a small corner of the TV screen so viewers can watch two programs simultaneously. The wife can watch her reality show, and man can play, or look back.

Response Time

The amount of time a pixel from black to white and vice versa. It 'like a camera shutter speed, the lower the number the faster, the better the image.

If you will be sitting 5-7 meters away, go up to 41 inches, 8-9 feet, up to 44 inches, 10-11 meters,up to 50 inches; 11-13 meters, up to 60 inches; 13-14 meters, up to 70 inches, about 15 meters, about 70 cm. Of course, really have not seen the opening of the first Star Wars

Film until it is seen sitting in a 5-inch 50-inch TV!

Mountains

Ideal for decorative systems clean - TV wall mounts you can hang the set on the wall like a painting. A couple of sentences with a TV wall, but most must be purchased separately. If you go this route, get a TV with a wide viewing angleSo you can see from the side and straight. Be sure to bring the TV support that securely and directly to the studs - flat-screen TV is not all that light. A shelf TV is another option, the Great Wall.
