As you buy a Television or a monitor, you will come across the acronym LED and LCD. The perception that many people have is that they are completely different technologies but in the actual meaning they are similar to one another.
By having this knowledge of the difference between the LED and the LCD displays, you will be able to make the appropriate choice of the type of screen to buy.

What Is an LCD Display?
The Liquid Crystal Display is also referred to as LCD.
LCD screen The LCD screen entails the utilization of liquid crystals in showing pictures. But liquid crystals do not emit light. They must possess a light behind in order to lighten the screen.
The conventional LCD display has the backlight, which is usually a combination of CCFL (Cold Cathode Fluorescent Lamps).
How LCD Works:
1. The screen is through which a fluorescent screen light travels.
2. Liquid crystals regulate the amount of light that is passed through.
3. The last picture is an output of color filters.
Key Features of LCD:
• Uses fluorescent backlight
• Thin and lightweight
• Energy saving compared to the old CRT monitors.
• Affordable

What Is an LED Display?
LED is an abbreviation, i.e., Light Emitting Diode.
The LCD display is literally LED display. The major difference is the technology of the backlighting.
The LED lights are used as the backlight in the LED displays instead of fluorescent lamps.
How LED Works:
1. LED lights are used to provide backlighting.
2. The image is projected on the screen.
As a technical matter, LED is therefore a superior variant of LCD.

The key distinctions between the LED and LCD include the following.
| Feature | LCD | LED |
| Backlight Type | CCFL (Fluorescent) | CCFL lights LED lights |
| Power Consumption | High | Low |
| Lightness | Average light | Brighter |
| Picture Quality | Good | Greater contrast and color |
| Thickness | Partly thicker | Thinner |
| Lifespan | Shorter | Longer |
| Price | Tend to be lower priced | A price slightly higher |

Picture Quality Comparison
Brightness
LED back lights are more effective and strong therefore the brightness of LED displays.
Contrast
The LED displays are known to have more contrast values especially when the advanced technology is applied like a local dimming.
Color Accuracy
LED indicators have a higher color.
________________________________________
Energy Efficiency
The LED displays consume less power in comparison with the traditional LCD displays that use fluorescent background lights.
This makes the LED screens more environmentally friendly and cost-effective in the long term.

Design and Thickness
LED displays are generally:
• Thinner
• Lighter
• More modern in appearance
Those displays with the backlight of LCD are slightly fatter in view of the distance between fluorescent lamps.
________________________________________
Lifespan
LED backlights last longer than the fluorescent backlights hence they are long lasting.
________________________________________
Types of LED Displays
The LED back lighting can be in the following forms:
1. Edge-lit LED
2. Full-array LED
3. LED with local dimming
The technologies increase brightness and contrast.

Advantages of LCD
• Lower initial cost
• Good image quality
• Reliable technology
________________________________________
Advantages of LED
• Better brightness
• Higher contrast
• Lower power consumption
• Slim design
• Longer lifespan

Which One Should You Choose?
Choose LCD if:
• You would find a cheaper solution.
Picture quality in the elementaries is sufficient.
Choose LED if:
• You want pictures of better quality.
• You prefer a thinner design
• You want energy efficiency
• You want longer lifespan

Final Conclusion
Both LCD and LED are close to each other. LED display is a high end LCD display with improved backlighting.
LCD is cheaper but LED is more illuminated, has a higher contrast, consumes less energy, and has a greater life.
The LED displays are positive in the instance of most of the modern consumers.
