What is a DISADVANTAGE of LCD displays?

What is a DISADVANTAGE of LCD displays? Correct Answer They require an additional light source

Mechanism of LCD:

  • The LCD consists of a large number of pixels, or picture elements, consisting of liquid crystal molecules held between two sets of transparent electrodes.
  • The liquid crystals react in predictable ways when the electrical charge running between those electrodes is changed — meaning they twist and move in ways that let different amounts (and colors) of light through the crystals. 
  • When compared to the other type of flat-panel display (plasma), LCDs tend to be found on the smaller size of the spectrum.

 

Advantages of LCD

 

Disadvantages of LCD

 

Extremely high resolution

 

In high-temperature environments, there is a loss of contrast

It has no geometric distortion

Limited viewing angle and brightness

It is very compact, thin, and light CRT displays

 

It requires an additional light source

It does not affect by the magnetic fields

 

It consumes a lot of electricity which produces a lot of heat

Due to low power consumption, small heated emitted during operation

It has individually liquid crystals which can’t complete all block of the backlight
