The 7 Best Technologies Of The Colour Television

LCD TV vs Plasma TV Review

External looks are decidedly wrong when standing in the showroom looking for two secondary side. Both televisions is flat and thin, but use different techniques to bring you the same result.

How TV Works Plasma

Plasma engineering TV use the same basic technology as the fluorescent lamp. The screen is composed of cells. In each cell two glass panels are out with a thin gap filled with neon-xenon gas and then sealed in the form of plasma when it occurs. This gas is then electrically charged at specific intervals when the TV plasma is lit. The electrically charged gas then moves through the red phosphorus, green and blue (A phosphor is any substance which, when are exposed to radiation, emits visible light), the creation of the television image. These cells of phosphorus (red, green and blue phosphors) are called pixels.

Although Plasma television, eliminating the need for bulky picture tube and electron beam scanning of traditional televisions, and still employs the burning of phosphors to generate an image, Plasma televisions still suffer some drawbacks of traditional televisions, such as heat generation and screen-burn of static images.

How LCD TVs Work

LCD TVs use a different technology.

LCD panels are made from two sheets of transparent material, are so polarized and glued together. One of the layers is coated with a chemical compound that contains specific separate LCD. An electrical charge passes through the crystals, the crystals can let light through or block light, creating your image.

LCD glass not produce light on themselves, then a light source, a bit like fluorescent tubes needed LCD screen to produce a visible image.

Unlike of old-style TV or plasma screen, but not matches should be under tension, it takes less power and less heat is generated in a plasma or older CRT style TV. Furthermore, there is radiation emitted by the LCD.

LCD vs Plasma

LCD Plasma Plus BENEFITS:

1. Access the screen is big.
2. deeper blacks for improved contrast ratio.
3. Lighter colors and color saturation.
4. Good movement monitoring lag Motion little or nothing in particular, with fast moving images.

The disadvantages of Plasma vs LCD include:

1. Plasma TVs are more susceptible to burn due to static images. It's like when you see a bright light and then close your eyes and can still see the light. It is, but can be a pain in the thigh.
2. Plasma TVs generate more heat than LCDs, because the light of phosphors to create images.
3. Does not work well at high altitudes.
4. shorter screen life (about 30,000 hours, equivalent to 8 hours of listening per day for 9 years). The good news is that life is improving screen to achieve at least hours due to improvements 60,000.

The advantages of LCD over plasma are:

1. No burn-in effect of static images.
2. Use less energy than running at a cool temperature.
3. No problems using higher altitudes.
4. There is an increased brightness of the image.
5. Longer Life screen (approximately 60,000 hours – probably all you need do is replace light source, not all).
6. Less than a plasma TV so that Pesa is easier to mount on a wall.

DISADVANTAGES of LCD versus plasma televisions are:

1. Less than a hand, you do not get deep blacks a plasma for this image clear.
2. Do not follow the same motion (fast moving objects can be a little nervous) – However, better and better with the screen refresh rate design of the LCD 120Hz high end.
3. Hard to find the screen size bigger. But they are beginning to show in the market price high.
4. LCD TVs usually cost more than same size LCD TV, LCD, but prices are falling due to increased production.
