What Is LCD Display?

Television display technologies are important for us to get the best experience possible when we are using our technological devices to watch something or play games.

Every display technology has its own way of working, and they are better than their predecessors in different ways.

One of those display technologies is the LCD display. We will talk about what an LCD display is and explain it further.


What Is LCD Display?

Coming right after gas-plasma displays and light-emitting diode (LED) technologies, LCD is a panel display that uses liquid crystals to operate, different than light-emitting diodes in LED technologies.

LCDs are extremely common for use both for individuals and businesses as you can find them everywhere, from smartphones to televisions.

These can make the displays we are using way thinner than the CRT technology.

LCDs also use less electricity than their predecessors because instead of emitting the light like the LED technology, they block it and produce an image using a backlight.

LCDs have taken the place of LEDs extremely quickly, and now they are nearly everywhere on most technological devices with a screen.

How LCDs Work

There are millions of pixels within a screen display, and the quality of the display is generally the number of pixels on the screen.

This means that the higher the pixel and resolution number, the better the quality of the display screen.

These pixels mostly have three subpixels: red, blue, and green. By changing the subpixels in a pixel, you get millions of different colors.

Each display type controls these pixels differently in a display. With LCDs, these pixels are lit by a backlight, and they switch the pixels on and off electronically and polarize the light by using the liquid crystals.

In simpler terms, this means that LCDs can provide a smoother light in the screen display while using less electricity than their predecessors.

Some LCDs also have dual scanning; they can scan the entire grid twice, which gives a better and crisper view on your screen display. 

There are a variety of LCD TV sizes available on the market, ranging from small-screen models that are ideal for bedroom viewing or kitchens to large-screen models that are perfect for living rooms or home theater setups.

The most popular LCD TV sizes are 32 inches, 40 inches, and 60 inches, although there are also larger and smaller options available.


LCD Types

  • Twisted Nematic (TN): Twisted nematic LCD type has a low contrast ratio, color contrast, and fewer viewing angles. However, they are not expensive and have a high response time.
  • In Panel Switching Displays (IPS): IPS panels have a better contrast ratio, color contrast, and viewing angles compared to TN panels.
  • Vertical Alignment Panels (VA): These panels sit right between TN and IPS panels in terms of quality.
  • Advanced Fringe Field Switching (AFFS): AFFS is one of the best LCD technologies in its color reproduction range when you compare it to other LCD types.

The Verdict

To sum everything up, LCD technology is slowly taking over its predecessors, LED and gas-emitting screen displays.

LCDs work with liquid crystals and use less electricity while giving better color contrast and viewing experience in general, thanks to more color range and the way the pixels work with a backlight in the screen display.

LCDs are extremely common to find in most technological devices with a screen, and they have four different types depending on the quality you are looking for.

Some are cheap, and some are expensive, but they give you different quality.
