| Both of the technologies have their own pros and | | | | LCD televisions usually don't face this problem and are |

| Plasma TV has some important advantages. It has | | | | usually heavy than the LCD television and it is more |
| brilliant picture quality because it can display deep black | | | | difficult to install it. Heavier size makes it difficult to |
| color very accurately. This helps to produce pictures | | | | move from one place to another. |
| with very good contrast, hence improving its quality. | | | | Plasma television is available in screen size ranging |
| This property is very important while watching movie | | | | from 32" to 100". LCD television in screen size greater |
| especially darker scenes. In case of LCD, backlight is | | | | than 37" is generally not found because transistors |
| used to fall on compact arrangement of cells to | | | | show very poor results above this screen size. LCD |
