LED stands for light-emitting diode. It was invented by Shuji Nakamura, Nick HOLONYAK, OLEG LOSEV. LED screens are the most commonly used screens. They are available in different sizes, shapes. We normally measured the sized diagonally. The popular sizes are 32″, 43″,50″,55″,60″,65″,70″,75″,80″ and 85″.  According to their sizes, their prices increase or decrease. The screen not only used for computer screens or TV. It is also used as laptop screens.


LED screens are consisting of two parallel plates that are polarized. On one sheet there is a positive charge where the second sheet contains the positive charges.


LED works with the flow of electric current. When the screen comes in contact with the electricity, as current flows, the electrons start to collide, causes the image to display on the screen. In laptops, as we press the power button due to battery we can see the images or graphics on the screens.


Here some of the advantages of LED given below:

  1. LEDs are smaller in size.
  2. It is lighter in weight.
  3. It consumes less power.
  4. It consists of uniform lighting.
  5. It provides a higher resolution (maximum no.of pixels).
  6. It is environmentally friendly due to its mercury-free technology.
  7. In day and night, they provide optimal viewing.
  8. LEDs have a wider viewing angle means at larger distance we can see a clear image.
  9. LEDs have energy efficiency.
  10. LEDs are long-lasting ability.


Here are some of the disadvantages of the LED.

  1. LEDs are expensive.
  2. Due to age and temperature LEDs can shift colours. Shifting of colour occurs due to UV exposure.
  3. Spending more time in front of LEDs causes severe eye damage as it emits blue light.
  4. It is not good with a static picture. A long-lasting static picture causes black lines on the screen.
  5. Maximum use causes the overheating that reduce its life.
