Difference between PLS LCD panel, IPS panel and MVA panel

- Apr 15, 2020-

Everyone knows that the mainstream types of LCD screens are roughly divided into IPS, MVA and PLS, each with different characteristics. In addition to these three mainstream screens, there is also a screen called TN screen. This kind of screen has slowly faded out of people's sight. The TN screen is the favorite of competitive gamers. Its response speed is fast. However, in order to adapt to the speed, it also has many disadvantages. For example, the TN screen is not rich enough in color Stiff and unsatisfactory in gray scale performance, it can be seen that the progress is not good. Although these shortcomings of high-end TN screens gradually improved in the later period, they are not recommended for ordinary users because of the high price.

 

Next, we will introduce the characteristics of these different displays:

 

Difference between PLS LCD panel, IPS panel and MVA panel

 

1. MVA screen

 

The full name of MVA is Multi-domain Vertical Alignment, which was developed by Fututong in 1998. Its performance is between TN and IPS screens. The original purpose of this display screen is to improve the viewing area. When the liquid crystal molecules are static, They are not arranged vertically. Therefore, when pressure is applied, the liquid crystal molecules will be arranged horizontally, so that the backlight can smoothly pass through the layers.

 

Because of this principle, MVA sacrifices the advantages of brightness and response time, but MVA has softer colors, wider viewing angles and contrast. As the IPS display has begun to reduce costs and popularized the entry-level market, the cost of MVA will also change. According to relevant experts predict that the cost of MVA will soon be reduced, and will occupy a larger entry-level screen market. Compared with IPS, the brightness of MVA is insufficient, but the color will be softer, and the performance of MVA's low light leakage will also be chased by many users.

 

2. PLS and IPS screen

 

The full name of PLS is Super PLS (Plane-to-Line), which belongs to a panel developed and manufactured by Samsung with exclusive technology. The full name of IPS is In-Plane Switching. The characteristics of PLS are almost the same as IPS. It has the characteristics of IPS "hard screen": good brightness, fast response speed, but high light leakage rate. This is exactly the opposite of the characteristics of MVA, which belongs to "soft screen". For the comparison between PLS and IPS screens, PLS displays are still better than IPS in terms of viewing angle and brightness, so in the evaluation, there is an order of PLSIPS> MVA.

 

For the "hard screen", high light leakage is inevitable, even Samsung's original screen also has problems in this regard. As the brand choice of PLS, it is divided into original factory and non-original factory. The original factory is produced by Samsung, and the non-original factory mainly includes the two brands of AOC and Philips. The prices of the two are also very different. Samsung's original products of the same specifications and models will be 100-300 yuan more expensive than non-original products.

 

3. Which panel is better for PLS, IPS and MVA?

 

First look at the comparison of TN, MVA, PLS viewing angle comparison parameters

 

TN, MVA, PLS parameter comparison

 

In terms of selection, PLS and IPS can be counted as "hard screen" type, their performance is not much different, game enthusiasts recommend choosing this screen. The MVA is a "soft screen" with soft colors, suitable for office workers who use computers for a long time.

 

The main difference between "hard screen" and "soft screen" is the problem of light leakage. In the dark environment, the contrast between IPS and PLS high light leakage display and MVA low light leakage display is obvious. If the light leakage phenomenon of PLS display screen and IPS display screen is acceptable, you can choose from these two display screens. According to the relevant parameters, PLS shows better performance than IPS. The technology of these two displays is very close, and the performance gap we can feel is minimal. It is generally recommended to choose IPS LCD screen. The price of this display is relatively low, and there will be more selectivity such as brand models.
