- Emit very little radiation harmful (some models have not emit any harmful radiation);
- Recent models have corrections of distortions, leaving the state harmonic images and more real, even in motion.
Disadvantages of LCD TV
- They have a limited view angle perpendicular (90 °), suffering from the problem of black light and white light , although this only occurs in older models. Currently, most LCD monitors reach 178 ° vision.
- The persistence of the logic state of the pixels LCD effects can lead to "drag" in the display of moving images.

- It has good definition sources SDTV , analog broadcast TV and cable, DVD, SKY SD (480i).
PLasma TV
Plasma TV: Advantages:
- Improved uniformity of light in all parts of the screen.
- Better viewing angle, suitable for larger sites.
Disadvantages:
- Increased rate of wear in the sources to excite the cells.
- Enhanced electromagnetic emission and incidence of ultraviolet light, which is bad for your health.
- Greater depth of the device and therefore heavier.
LED TV: Advantages
- Stay with Low Power Consumption - Increased uniformity of the backlight
- Best resolution component video and HDMI
- Depth further reduced - the LEDs occupy less space than the bulbs (back light)
Disadvantages
Also has a low resolution analog composite video - How is a new technology, the cost is still too high
