An LCD (Liquid Crystal Display) is a type of display technology that uses liquid displaying crystals to create an image. It consists of two layers of glass or plastic, with a layer of liquid crystals sandwiched between them. When an electric current is applied to the liquid crystals, they align in a specific way and allow light to pass through, creating an image on the display.

LCDs have become an integral part of our daily lives, found in everything from televisions and computer monitors to smartphones and digital clocks. But as with any technology, there are pros and cons to consider when deciding whether or not to use LCDs.

Why is it so popular?

One of the main reasons for the popularity of LCDs is the fact that they can be produced in a wide range of sizes and shapes, making them suitable for use in a variety of different products. This flexibility is especially important in the rapidly evolving world of consumer electronics, where devices are getting smaller and more portable all the time.

Another factor that has contributed to the widespread adoption of LCDs is the fact that they are relatively easy to produce and assemble. Unlike other display technologies, which may require more complex manufacturing processes, LCDs can be produced using a relatively simple and cost-effective process. This has made them a popular choice for manufacturers looking to produce large quantities of display panels at a low cost.

So, should we use LCDs or not? The answer ultimately depends on your specific needs and priorities.

If you prioritize cost and energy efficiency, then LCDs may be the right choice for you. However, if picture quality and image retention are concerns, then you may want to consider other options such as OLED displays.

It’s also worth noting that LCD technology is constantly evolving, and newer models may offer improvements in picture quality and other areas. So, if you are considering using LCDs, be sure to do your research and choose the model that best fits your needs.

Advantages of using a Liquid Crystal Displays

LCDs have many advantages that make them a popular choice for various uses. Few of them are

  • Good choice for portable devices like smartphones and laptops.
  • Wide viewing angle, which means that you can view the display from almost any angle and still get a clear image.
  • Relatively inexpensive to produce
  • Generally considered to be durable
  • More energy efficient compared to other display technologies
  • Have a long lifespan
  • Cost-effective choice for both manufacturers and consumers.

Drawbacks of LCDs

There are numerous drawbacks of this displaying crystals technology and few of them include:

  • Prone to damage if not handled properly
  • Can be damaged by water or other liquids, which can cause the screen to become distorted or inoperable.
  • Lower picture quality compared to other display technologies, such as OLED (Organic Light Emitting Diode) displays.
  • LCDs cannot offer what an OLED offers. An OLED display offers deeper blacks and a wider color gamut, which can lead to a more vivid and lifelike image.
  • Another potential issue with LCDs is their susceptibility to image retention, also known as “burn-in.”
  • When a static image is displayed on an LCD screen for an extended period of time, it causes the pixels to become stuck in a certain position and leaving a permanent ghost image on the screen.
  • They are problematic for television and computer monitors, where static images may be displayed for long periods of time.
  • Energy-intensive production process
  • Produce harmful emissions while manufacturing
  • LCDs contain rare earth minerals, and their mining process can have negative environmental impacts.

However, it’s important to note that the environmental impact of LCDs has decreased significantly in recent years due to advances in manufacturing techniques and the use of more eco-friendly materials. For example, many LCD manufacturers have switched to using mercury-free backlighting, which reduces the environmental impact of the production process.

Despite these drawbacks, LCDs are still a popular choice for many applications due to their low cost and long lifespan. In fact, LCDs are the dominant display technology in the market, with a share of over 90% in the global display market, as per a report by statista. In addition to their use in televisions and computer monitors, LCDs are also found in a wide range of other applications, including appliances, digital signage, and medical equipment.

To conclude, LCDs are a popular choice for many applications due to their low power consumption, wide viewing angles, and low cost. Industry experts and satisfied consumers alike have praised the technology for its energy efficiency and cost-effectiveness.

LCDs require very little maintenance compared to other display technologies, such as CRT displays. They do not require regular cleaning or adjustments like CRT displays, making them a convenient choice for many applications.

The data shows that LCDs have a dominant market share and are widely adopted in a variety of applications. However, it’s important to consider the potential drawbacks of LCDs, including lower picture quality compared to other technologies, susceptibility to image retention, and environmental impact, when deciding whether or not to use them.

Therefore, be wise to gauge the benefits and drawbacks of LCD based on your needs before making a purchase.
