Difference Between LED vs. LCD


Main Difference

As modern technology has been providing number of novel tools and devices to facilitate lives of twenty-first centuries’ people, sometimes few items correlate to confuse the consumers. The same is the case with LED and LCD. Both are terms used for a display machine being used as an upgraded form of the Television. First of all, LCD is the precursor of LED. In other words, LCD is the predecessor of LED and both of them are the next generation devices to be used as televisions. LCD screen is developed with liquid-crystal gel sandwich heed. LED is not lit employing fluorescent tubes as number of light emitting diodes takes the responsibility. LCD is made with flat panel display to allow light either to pass or block. LED, on the other hand, is used to backlight LCD displays, resulting in a conspicuous image. LCD can’t generate its own light and this task is taken by additional lighting. Although LCD is a sort of tiny form of TV, it is still considered as bigger when compared with LED which is comparatively smaller than CCFL tunes, meaning LED can even be made smaller. Both these technologies are made to consume less energy but LED needs the least power to function. LCD utilizes the light-modulating properties of liquid crystals, which do not let the light to get out. There is a p-n junction diode in LED which works to let the light get activated. As appropriate voltage is applied to the leads, the electrons in LED start recombining with electron holes within the device and discharge energy in the form of photons. LCD is can be used in a vast array of appliances like computer monitor, television, instrument panel, aircraft cockpit display etc. Screen size for both these entities is the same but there is a difference of price as LED is cheap than LCD.

Definition of LED

LED is the abbreviation of Light Emitting Diode, which is a two-lead semiconductor light source. LED is the advanced form of its predecessor LCD and it is relatively small in size and may utilize integrated optical components to form its radiation pattern. LED can be available across the visible, ultraviolet and infrared wavelengths having extremely high brightness. LED has advantage over its precursor in that it consumes less energy and takes comparatively less space with best results.

Definition of LCD

LCD is basically the abbreviated form of Liquid-Crystal Display having a flat-panel or other electronic visual display that borrows light-modulating properties of liquid crystals. LCD works to display arbitrary images or goes to fix images with low information content. The technology works in vast array of applications and devices including computer, television, instrument panel, aircraft cockpit display etc. The screen of this gadget is more energy-efficient.


Differences in a Nutshell

  1. LCD is older than LED
  2. LCD is the predecessor to LED
  3. LED is thinner than LCD
  4. LED takes less space and consumes less energy as compared to LCD
  5. Dynamic Image Contrast is better in LED
