Types of TVs
Direct View - Tube A tube television is what we (over 40) are accustomed to, before all this fast-changing technology. The picture device is a cathode ray tube. These tubes come in various sizes up to about 40-inches. They dont cost as much as other TVs. As you know, they can be bulky but last a long time. Digital Light Processing (DLP) Digital Light Processing was invented in 1987. Over fifty manufacturers produce at least one model of a DLP television. They come in rear and front projection. Liquid Crystal Display (LCD) They come in either flat panel or rear projection. Flat panel displays are a lot more popular because they are thin and lightweight. You can use your LCD as a TV and also a computer monitor. The average lifespan of one of these displays is 60,000 hours. If you watch TV 8 hour per day, it would take about 20 years to wear out the LCD display. (FYI-Because of the LCD technology, there is no radiation emitted from the screen, unlike traditional televisions). Plasma Display Panels (PDP) Plasma television technology is based loosely on the fluorescent lightbulb Plasma is associated with high end home electronics. All plasma televisions come in flat panels and most are sized in the 40-49" range. They should last anywhere from 10-20 years. Consider when buying A TV 1. THE SIZE. How far away from the TV will you be sitting? For 20 to 27-inch TVs, you should be from 2.5 to 5 feet away. For 32 to 37-inch TVs, you should be from 6 to 8 feet away. For 42 to 46-inch TVs, you should be from 10 to 14 feet away. For 50-inch TVs, you should be from 12 to 16 feet away. 2. Determine how youre going to install the LCD TV. There are more options than simply TV Stands. Here are the options: Flat Screen TV Wall Mounts This LCD wall mount option is generally the least expensive, and it adds just under two inches to the monitor's total depth. Tilt Wall Mounts enable you to place your TV above eye level, keeping it out of the way. This option is typically used to install LCD monitors above fireplaces and in bedrooms. The tilt wall mount adds from 4 to 6 inches to the depth of the mounted display. Plasma Table Stands are another popular way to display LCD units. Realize, though, that these units are not one-size-fits-all appliances. Each display has its own custom-fitted table stand. Articulating Wall Mounts make use of swivel arms to render the LCD unit flush with the wall-and out of the way-when not in use. Pulled out, this mounting device allows you to turn the display 120° to either side and as much as 10° up or down. Ceiling Mounts enable you to mount your TV where you want it-in the event that a wall isn't handy. This option is generally coupled with a tilt mount, so that the display can be adjusted downward for easier viewing. Lengths of ceiling mount poles vary according to customer needs, though the standard lengths are from 24 to 43 inches.
