In today's post, we will know what is called LCD and LED and what is the difference between LCD and LED in Difference Between LCD and LED?
What is the difference between LCD and LED?
Both LCD and LED are very similar to each other, that is why most of the people get confused between them that what is the difference between LCD and LED, but it is important to keep in mind that despite being similar, both LCD and LED are related to each other. Quite different.
If we talk about the main difference between LED and LCD, then it is that LED uses PN-junction diode, it emits light when current passes through it whereas LCD uses liquid crystal for visible light emission. This plasma is used. The liquid crystals are filled between the glass electrodes and when the LCD is turned on, the liquid crystal is activated and emits light.
There are many differences between LCD and LED, which we will understand one by one through the difference table, but before that let us know better what is called LCD and LED.
What is the LCD - What is an LCD?
LCD display screen is a flat display technology used in laptops, cell phones, calculators, digital cameras and flat screen displays. LCD, whose full form is liquid crystal display, is a passive device that does not have any light to display text or media. Instead of its own light, LCD uses fluorescent tubes that produce light and help lighten the picture. does. In LCD, the light is always placed behind the screen panel.
Produces content in the form of a dot matrix or segment on an LCD screen. A liquid crystal filament is filled between the transparent electrodes, and current is passed through it to energize the filaments. It helps in emitting visible lights.
LCD provides very good color accuracy and you can see the content of its screen clear even from 30 degrees. Some advantages and disadvantages of LCD are given below.
Advantages of LCD
Following are some of the essential advantages of LCD.
- LCD is a bit cheap.
- The LCD is much lighter than the older CRT displays.
- The LCD provides excellent brightness.
- LCD has better wide viewing angles.
Disadvantages of LCD
Below are the most common disadvantages of LCDs:
- It needs an additional light source.
- It has also limited the viewing angle.
- Its speed is slower than LED
What is an LED ?
LED whose full form is light-emitting diode. LEDs are a subset of LCDs, which technically use liquid crystal displays. However, it differs from LCD because LCDs use fluorescent light while LEDs use light-emitting diodes.
These diodes are commonly referred to as semiconductor light sources which produce light when a current is passed through them. In LED this diode mechanism produces better and picture than in normal LCD. In LED the light-emitting diodes can be placed behind or around the edges of the screen panel.
Uses of LED
LED provides very good picture quality and it also consumes very less power. Nowadays LED display screens are used for laptops, cell phones, calculators, digital cameras and flat screen displays.
- Used for TV back-lighting
- Uses in displays
- Used in automotive
- LEDs used in the dimming of lights
Advantages of LED
Some of the essential benefits of LED are listed below:
- LEDs are very strong and durable.
- It requires less maintenance.
- LED does not heat.
- LED is highly efficient.
Disadvantages of LED
Some Disadvantages of LED are listed below:
- LED is more expensive.
- The picture does not look good when viewed from the side of the LED screen.
- The cost of repairing an LED is high because the parts of the LED are very expensive.
Major Differences between LCD and LED in English
So far above, we have known that what are LCD and LED, if you have read all the things given above carefully, then you must have come to know about the difference between LCD and LED.
