LCD and LED are two optical devices that use backlights. LCD is the abbreviation of Liquid Crystal Display and uses fluorescent lights and are behind the screen.
Main Difference
On the other hand, LED is the short form of Light Emitting Diode. Both devices, like Television and are highly demanded all over the world. Moreover, LED offers better picture quality as compared to LCD. Let us discuss the main differences between LCD and LED in detail.
What is LCD?
The complete form of LCD is Liquid Crystal Display and is used as the replacement for Television. It can be attached or fitted on walls or tables by its stand. This paned is reasonable for projecting on-screen information with large screen sizes. Moreover, LCD used liquid crystals in operations. It offers good-quality pictures; a crowd can view it at once due to its great size.
Furthermore, it is an efficient display and uses lower power. LCDs have many components, such as a polarizer, color filter, diffuser, light source, and more. In addition, users can buy LCDs at a competitive price. Lastly, LCD screens can be replaced in case of damage or error.
Advantages
- Thin body
- Space saving and can adjust anywhere
- Good picture quality
- Not produce temperature
- Cost-effective
- It does not release radiation
Disadvantages
- The deflection angle of vision is small
- Not high-quality picture
- Resolution is lower
- Color contrast is low
What is LED?
The complete form of LED is Light Emitting Diode and is used as a light source in some electrical equipment. It is a semiconductor device that emits rays in the form of radiations when an electric current flows through it. Moreover, the quality of the picture is very high. It releases energy in the form of heat and photons. Furthermore, LED is used in several fields, such as remote control, security systems, optical devices, etc. Also, it operates in displays. In addition, LEDs have various types.
Advantages
- Consumes less power
- Light is monochromatic
- There is no need for warm-up
- Require low operational voltage
- Long lasting display
Disadvantages
- Cost is high
- No standardization
- Transform compatibility
Major differences between LCD and LED
- The picture quality of LED is much high as compared to LCD.
- LED is more expensive in contrast to LCD.
- LED uses less power energy, and LCD uses more power energy.
- LED, in contrast to LCD, offers more colors.
- The burn-in LED is very rare, while LCD has no burn-in issue.
- LED is thinner as compared to LCD.
Comparison table between LCD and LED.
| Features | LCD | LED |
| Cost | Less expensive | More expensive |
| Picture quality | Picture quality is good | Picture quality is good |
| Energy consumption | Use high energy | Use low energy |
| Full form | Liquid crystals display | Light emitting device |
Conclusion
In a nutshell, we can say that both LCD and LED are different. There differ in terms of their features and uses.
