What Is Difference Between LCD And LED In Electronics


Electronic Technologies are also updating with the pulse rate in current century in competition to other technologies. LCD and LED are two display technologies of electronics. LCD means “Liquid Crystal Diode” and LED means Light Emitting Diode. Both technologies are referred to similar to some extent but also differ from some point which we are going to describe below. LCD is only used as display device whereas the LED is also used in various other applications, such as flashlights and indicators. LCD’s is a device comprised of multiple components but LED is comprised of the single component device. Light Emitting Diodes LED are capable of producing light whereas LCD as not able to produce light. There are also huge differences between the viewing angle and the color accuracy of both LCD’s and LED’s. Here below you can easily find the best material regarding the difference between LCD and LED. it is all about the What Is Difference Between LCD And LED In Electronics

What is LCD?

LCD stands for Liquid Display Diode. It is a multi-display component diode and consumes more power having operating voltage range is 3 to 20 VDC. LCD is an old display technology which is replaced with LED. The liquid crystal display comprised of a thin layer of transparent liquid crystal material between two electrodes. The lifetime of liquid crystal diodes due to chemical degradation is about 50,000 hours which is less than Light Emitting Diodes. Its operating temperature range from -20 to 60 degree Celsius.

What is LED?

LED stands for Light Emitting Diode. It refers to the single component device and consumes less power having operating voltage range 1.5V to 5VDC. LED is a more advanced display technology with advanced features and properties as compared to LCD. The lifetime of Light Emitting Diode LED is more than LCD which is 100,000 hours. The operating temperature of commercially available LED’s is ranges from -40 to 80 degree Celsius.

Key Difference between LCD and LED:

The key difference between LCD and LED can be abstract from the below-listed points.

LCD LED
LCD stands for “Liquid Crystal Display” LED stands for “Light Emitting Diode”
LCD has thicker screen LED has thinner screen display
The viewing angle of LED is 100 degree the viewing angle of LED is wider ranges 150 degrees
LCD’s have a moderate level of brightness LED’s have very good brightness
LCD’s consume more power LED’s consume less power
LCD is multiple component devices LED is a single component device
Due to less power requirement, Driver Circuits are not required it drives directly from IC (Integrated Circuit) chips due to high power requirement LED requires external interface circuit (LED Driver Circuit)
Due to chemical degradation the life time of LCD is 50,000 hours the life time of LED is 100,000 hours
