[Exact] Comparison between TN, VA, IPS Panel LCD Display



TN, VA, IPS Panel LCD Display


There are mainly three types of panels used in LCD displays. The three panels are TN(twisted nematic), VA(Vertical Alignment), and IPS(In-Plane Switching). Each type of panels have their own advantages, disadvantages, and features. They are used in LCD(Liquid Crystal Display) according to the quality picture, price, viewing angles, etc. In this article, we are going to know the exact comparison between TN, VA, IPS Panel LCD display.



TN Panel LCD Display


Under the application of the electrical field, the alignment of liquid crystal molecules changes which is known as the Twisted Nematic(TN) effect. When a video signal is applied to LCD, liquid crystal molecules change their alignments and produce images. Normally, the molecules are separated by several spacers and coated with electrodes. When the voltage applied, they re-align and display the information.

In TN panel technology, transparent electrodes are used and they placed with a matrix pattern. The amount of opacity of the image can be controlled by varying the applied voltage. Normally, 1V is enough to realign the crystal molecules. When the voltage applied to that crystal molecules no current flow through the molecules. For this reason, TN panel technology required very little electrical power. TN panel LCD display provides 160 degrees viewable angle.





Advantages of TN Panel LCD Display


1. The main advantage of the TN panel LCD display is it takes very little electrical power.

2. TN panel LCD displays provide good color combinations but reflect in the display properly.

3. The calibration of the TN panel is easier than other LCD panels that's why it provides a very good word consistency.

4. TN Panel LCD displays have very good response times that's why they are the most suitable for gaming graphics.

5. TN panel having simple circuits and it also a low-cost device.





Disadvantages of TN Panel LCD Display


1. TN panel LCD displays have the worst viewing angle.

2. It provides low colorful pictures.

3. It provides low contrast and low brightness picture quality.





VA Panel LCD Display


VA stands for Vertical alignment. In VA displays, liquid crystals are normally vertically alignment and light placed its backside. When a voltage applied across them they get tilt and light passes through it and produce images. In VA panels, liquid crystals are placed with the perpendicular to the substrates.

VA panels are manufactured nearly similar to TN panels with some extra features and improvements. VA panels have a great ability to block the light coming from the backlight when it is not wanted. For this reason, it provides good contrast ratios, good word considerations.

Compared to TN panels, VA panels provide more viewing angles, very good color reproduction, higher refresh rates, more brightness, etc.



Advantages of VA Panel LCD Display


1. It provides a very good refresh rate (above 60HZ).

2. It has a great ability to block backlight so it provides a high contrast ratio, good word considerations.

3. It has a very good color reproduction feature.

4. It provides more brightness than TN panel displays.

5. It provides more viewing angles than TN displays.





Disadvantages of VA Panel LCD Display


1. The main disadvantage of this type of display is, it has a low level of responsiveness, for this reason, it creates blurring in fast-moving pictures such as gamming.

2. It takes more electrical power than TN Panel displays.

3. It provides higher viewing angles than TN panel displays but lower than IPS panel displays.



IPS Panel LCD Display


IPS stands for In-Plane Switching. In IPS panels, the liquid crystals are placed in parallel with the glass substrate. When the voltage applied across the crystal its orientation gets changes and produces images. The molecular structure of the IPS panel is nearly the same as the TN panel. Only the arrangement of electrodes is different. Electrodes in the IPS panel are placed in the same plane with the glass substrate.

IPS panel takes much more electrical power than other panels. The IPS panel has very little color shift when changing the viewing angles. As the liquid crystals placed in the same plane or parallel with the glass substrate that's why it is called In-Plane Switching.



Advantages of IPS Panel LCD Display


1. This type of display provides very good word consistency, wider viewing angles.

2. They provide wider viewing angles than other display panels.

3. They provide much more brightness, contrast ratios, color combinations, etc.

4. They offer stable response times, high refresh rates.

5. IPS panel LCD displays are perfect for touch screen devices.





Disadvantages of IPS Panel LCD Display


1. IPS panel displays take much more electrical power almost 15 times more than a TN panel display.

2. IPS panels displays have worse response rates.

3. IPS panel display has a higher production cost that's why they are costlier than other panels.
