Plasma and LCD technology - what's the difference?
Despite the flat screen and thin profile, plasma and lcd screen are very different. Plasma screens uses a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens are made up of liquid crystal pushed, acting as light filterm in the space between two glass plates. Images are created by varying the amount electrical charge applied to the crystals.
Picture quality between flat screen and CRT tv's
Both plasma and LCD sets produce excellent pictures, although many home entertainment specialists and gamers still say CRTs produce the best overall images. In the flat screens galaxy, plasma screens have a slight edge over LCDs. This is because plasma screens can display blacks more accurately than LCDs can, which means better contrast and detail in dark-coloured television or movie scenes. The nature of LCD technology, where a backlight shines through the LCD layer, means it's hard for it to achieve true blacks because there's always some light leakage from between pixels.
Advantages of plasma screens are:
- better contrast due to its ability to show deeper blacks;
- better viewing angles;
- brighter colour;
- LCD screens have a tendency to blur images, particularly during fast moving scenes in movies or in sports;
Advantages of LCD screens are:
- price competitive;
- higher native resolution (more pixels on a screen);
- consume less power;
- lighter than similar sized plasmas;
- longer lifespan;
- plasmas suffer from screen burn in;
- definition : number of dots on a screen.
- size : length of the diagonal of the screen.
- resolution : number dots per inches.
- response time : amount of time a pixel takes to go from black to white and back to black again. It is measured in milliseconds (ms).
- Viewing Angle: how far you can sit on either side of a screen before the picture's quality is affected.
- minimal resolution: 1024x780;
- brightness:450 cd/m2;
- contrast rate: up to 1000:1;
- HDMI and SCART
- Response time minus than 16 ms
- HD Ready or Full HD
