LCD Full Form, what is LCD?

What is LCD?

In this tutorial, I would like to Explain about LCD and LED, what is the difference between LCD and LED. LCD Full Form and LED Full-Form are clearly explained in detail on this website Circuits99.com.

This article is a detailed explanation of what an LCD is and how it works. It also goes over the different types of LCDs, their applications, and the components used to make them. The article also includes a link to a practical demonstration that uses a Liquid Crystal Display. This article is intended for those with a basic understanding of electronics who wants to learn more about the inner workings of an LCD.

The LCD (liquid-crystal display) was one of the first displays that were used in computers and TVs. The LCD uses liquid crystals instead of electric charges to change the way light is reflected on a screen, which allows for much more vivid, life-like images. These displays are known for their thin, energy-efficient screens and long product lifespans, making them a must-have in modern technology. However, the LCD has had a very interesting and sometimes controversial history, which is the focus of this article.

LCD stands for Liquid Crystal Display. LCDs are flat panel display technology and are used as screens in TVs and computer monitors, At present LCDs, are used in mobile phones also. These LCDs are completely different from that old CRT displays, it uses liquid crystals instead of cathode ray in their primary form of operation.

LCD Screen Working

The LCD display has millions of pixels which are made up of liquid crystals and arranged in a rectangular grid. Each pixel has a Red, Green, and Blue, often called RGB that can be turned On or Off. These sub-pixels are turned off in that case Black screen appears. when all the sub-pixels are turned On 100%, in that case, the screen gets white.

The LCD works on a combination of two states of matter, which are solid and liquid. The LCD consists of two layers they are polarized panels like filters and electrodes. The solid part is crystal and liquid and crystal together make a visible image. The LCD screen picture appears by blocking the light rather than emitting the light. The LCD has two types of pixel grids.

Advantages of LCD

  • It has low cost
  • Less power consumption and energy efficiency.
  • LCD monitors have less radiation than CRT monitors.
  • LCDs provide excellent contrast, brightness, and resolution as compared with CRTs.

Disadvantage of LCD

  • LCDs are less reliable displays.
  • LCD requires a backlight for lighting the pixels.
  • When in a low-intensity level of light, the LCD color saturation is reduced.
  • LCDs are fixed in resolution and ratio.
