1. LCD(Liquid Crystal Display):

LCD vs LED: types of display.

  • It has a low power consumption and a high-quality image.

  • It is utilised in a cathode ray tube.
  • The pixel is the smallest element of an image displayed on an LCD. Each pixel is made up of a layer of molecules that are perfectly aligned.
  • Between two transparent electrodes and two polarising filters, it was perfectly aligned.
  • The crystals do not directly emit light because it is a flat panel display.
  • It’s used to reflect images in colour or monochrome LCDs, which can be turned on (+ve) or off (-ve) depending on the polarizer arrangement.
  • Liquid crystal displays are utilised in a variety of applications, including LCD televisions, computers, monitors, and indoor and outdoor signs.
  • Digital cameras, watches, calculators, mobile phones, and smartphones all use small LCD screens.

2. LED( Light-Emitting Diode ):

  • It’s similar to an LED display, except that instead of using a light source, they utilise an LED bulb.

  • It’s a flat panel display with a video display that uses an array of LEDs as pixels.
  • Store signage and billboards use this brightness.

3. OLED( Organic Light-Emitting Diode OLED display ):

  • It’s also known as an organic electroluminescent diode (organic EL), and it’s a light-emitting diode (LED) with an emissive EL layer that emits light in response to an electric current.
  • Between two electrodes, at least one of which is transparent, is an organic layer.
  • Because it emits visible light, the display functions without a backlight.
  • In comparison to an LCD, it has a high contrast ratio.
  • A passive-matrix (PMOLED) or active-matrix (AMOLED) control method can be used to drive this display.

4. AMOLED( Active-Matrix Organic Light-Emitting Diode ):

  • Laptops, smartwatches, mobile devices, televisions, and digital cameras all utilise this display device technology.

  • Organic chemicals are used to make the electroluminescent material in this thin film display method.
  • It consists of AMOLED pixels that emit light (luminescence) when electrically activated and are positioned or integrated into a thin-film transistor (TFT) array, which acts as a series of switches to control the current flowing to each individual pixel.
  • It has a low power consumption and cost, as well as scalability.

5. Super AMOLED( Super Active-Matrix Organic Light-Emitting Diode ):

  • This is an AMOLED display in essence, although the word was developed for marketing purposes.

  • Although the touch detection layer is built into the screen rather than being placed on top of it, it is no better than the AMOLED display.
  • According to Samsung, Super AMOLED displays reflect one-fifth as much sunlight as first-generation AMOLED panels.
  • Super AMOLED displays, which are part of the Pentile matrix family, are sometimes referred to as SAMOLED.

Other Variation Of SAMOLED:

  1. Advanced Super AMOLED

  2. AMOLED Plus (Super AMOLED).
  3. HD Super AMOLED (High Definition Super AMOLED).
  4. HD Super AMOLED Plus is a high-definition Super AMOLED display.
  5. Super AMOLED Full HD                


  • It consists of pure monochromatic red, green, and blue semiconductor nanocrystals.
  • In a QD layer, photo-emissive quantum dot particles transform the backlight to pure basic colours, which improves display brightness while reducing light loss and colour crosstalk in RGB colour filters.
  • It’s akin to an AMOLED display.
  • Flat-panel TVs, digital cameras, mobile phones, and handheld game consoles all use it.
