LCD vs. LED: What’s the Difference Between the Displays?

Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between LED & LCD. The basic difference between LED and LCD is that in LED there is PN junction diode that releases light when current flow through it. While for the emission of light in LED liquid crystal or plasma is used. The liquid crystal is placed among the electrodes created with the glass when the input supply is given these liquid crystals get energy and release light.

Both LED and LCD are used to show different pictures and textual data. In LED gallium arsenide and gallium phosphide are used after getting of energy it releases light.  The LCD shown textual data and pictures in the shape of dot matrix. In today’s post, we will have a detailed look at both LCD and LED and compare them to find their differences. So let’s get started with Difference Between LED & LCD.

Difference Between LED & LCD

LED

• LED is a semiconductor device that releases light when current flows through it.
• It is such an electronic module that releases light when a voltage source is linked to it.

• It belongs to the family of semiconductor devices.
• Its resolution is larger than the LCD.
• It needed more power than the LCD.
• Its full form is a light-emitting diode
• It emits light when supply is connected to it then free electrons combine into a hole and release energy in the form of light.
• The color of the emitted light depends on the energy needed for electrons to leave the bandgap.
• LED uses less energy than a normal incandescent bulb, with less cost.
• It is employed in different areas, like the aviation industry, lights of vehicles, signal
• It does not need any backlight.
• Its switching speed is fast.
• There is no effect on the LED of DC.
• Its contrast ratio is less than the LCD.
• its display area is smaller than the LCD.
• It is created with the Gallium arsenide phosphide..

LCD

• The LCD screen comes with thin liquid crystal material placed between two electrodes on a glass substrate and two polarizers on any side.
• The polarizer is an optical filter that allows light rays of certain polarization to flow and block the light of the type of polarization.
• Electrodes used have a transparent nature and the famous type of material used is  (Indium Tin Oxide).
• The LCD does not release light on its own but it has a backlight for light production.
• Normally LED backlight is used. For color display color filter is added in the LCD cell. Colors normally are RGB
• It is less expensive than the LED.
• It is created with Liquid crystals and glass electrodes.
• Its contrast ratio is larger than the LED.
• It is used in different applications like TV, computer, and display.
• LCD projectors are also created. it used in mobile phone screen
• Its switching time is less than the LED.
• The DC affects its operating life by reducing Life Span.
