Everything LCD Display Technology: Understanding Contrast Ratio

More than the resolution, color, display size or other specifications of an LCD panel, contrast ratio make the “real” difference between a high- and a low-quality image. It’s what makes the good-looking image look good on the LCD and the bad-looking image look bad on the panel.

But what exactly is contrast ratio?

What is contrast ratio?

In simple words, contrast ratio is the difference between the brightest image and the darkest image which a LCD panel can create. In another way, whitest white/blackest black = contrast ratio.

Contrast ratio is typically written as a ratio of some to number to one. So, if an LCD panel has a contrast ratio of 6000:1, it would imply that the display can output the brightest image which would be 6000 times brighter than the blackest image it can produce.

A good contrast ratio for your LCD panel is vital to accomplishing a good display performance. When you insist on having a higher contrast ratio for your LCD panel, you secure the following benefits:

  • The pictures produced by the display feel more immersive
  • The pictures produced by the display feel more detailed
  • The colors produced by the display stand out more
  • The colors produced by the display look brighter
  • The content produced by the display is easier to read
  • The display doesn’t cause eye strain and fatigue

So, how can you accomplish a higher contrast ratio for your LCD panel?

Achieving a higher contrast ratio for your LCD panel

There are three main “controllable” factors that influence the contrast ratio of an LCD panel:

  • Native LCD technology (TN, IPS and VA)
  • Display brightness
  • Polarizer treatment

When speaking of native LCD technology, VA is the undisputed leader in terms of contrast ratio. The high contrast ratio ofa VA LCD panel can be attributed to the natural alignment of the liquid crystals found in the panel.

In case of display brightness, having a high brightness LCD always helps produce better contrast ratios. Aim for LCD panels that offer high luminosity levels.

Polarizer treatment also helps accomplish a higher contrast ratio by reducing the amount of reflection and glare in LCD panels. When purchasing an LCD panel, look for a supplier that offers AR- and AG-reinforced solutions to ensure the best quality product for your design needs.

Wrapping up

Contrast ratio is the most critical specification of an industrial LCD display. By choosing a LCD panel with a high contrast ratio, you can design a product that delivers the best viewing experience to your customers.
