Latest company news about TN vs. IPS vs. VA: What's the Best LCD Display Technology?

TN LCD

Twisted Nematic (TN) LCD is a common soft screen before, which can press the water ripple by hand. This is one of the LCD panels used earlier.

 

The advantages of TN LCD

  • Its technology is mature and widely used in the market.​
  • Good black levels.
  • The output gray class number is small, and the liquid crystal molecules deflect faster.
  • Fast response time, generally has a response time of 1 ms.

 

The disadvantages of TN LCD

  • Small viewing angle.
  • The display color is not bright and may be slightly whitish.

 

 

IPS LCD

 

In-Plane Switching (IPS) technology is a liquid crystal panel technology introduced in 2001, commonly known as "Super TFT".

 

The advantages of IPS LCD

  • High viewing angle (up to 178 °).
  • Fast response.
  • Accurate color restoration.

 

The disadvantages of IPS LCD

  • Light leakage is relatively serious.
  • and the black purity is not enough, which is slightly worse than PVA.
  • It is necessary to rely on the compensation of optical films to achieve a better black color.
  • Low price.

The screen of the IPS LCD is relatively "hard" and won't deform in the water pattern with a gentle stroke of the hand, so it is also known as a hard screen.

 

It eliminates the blurring and water-spreading phenomena that occur when traditional LCD screens are subjected to external pressure and shaking.

 

When playing extremely fast pictures, there will no longer be residual shadows and trailing phenomena.

 

IPS panels are very popular in industries such as industry, healthcare, and automotive.
 

 

VA LCD

 

Vertical alignment (VA) represents a vertical arrangement in which the liquid crystals are vertically arranged perpendicular to the surface of the substrate.

 

It can be subdivided into MVA (multi-domain vertical alignment) and PVA (patterned vertical alignment).

 

The advantages of VA LCD

  • Ultra-wide viewing angle
  • High contrast
  • The display screen is more delicate

 

The disadvantages of VA LCD

  • Color cohesion is not very good in dynamic images
  • High-speed images are prone to drag shadows
