Laptops and computer screens come in a variety of options, each offering different features and functionalities to cater to specific user needs. When it comes to the display technology, two commonly used types are In-Plane Switching (IPS) and Twisted Nematic (TN) screens. These display technologies have their own set of advantages and disadvantages, which impact factors like image quality, viewing angles, response times, and more. Understanding the differences between IPS and TN screens can help users make an informed decision when purchasing a laptop or computer screen. In this article, we will delve into the disparities between IPS and TN screens, highlight their respective advantages and disadvantages, and provide insights on how to identify these display technologies.
Often when choosing to buy a laptop, users often pay attention to the configuration and design but neglect some other important details, such as the computer screen. So do you know how many types of screens there are today and what are their advantages and disadvantages?
How many types of screens are available for laptops?
Currently, the laptop screen market is divided into 2 types corresponding to 2 different technologies, IPS and TN . Each of them has its own distinctive features.
TN (Twisted Nematic) screen, this is a screen that uses a crystal structure and has been on the market for quite a while. With low production costs , TN screens used to be very popular and equipped on many electronic devices such as laptops or even televisions.
IPS (In-plane Switching) is an imaging technology applied on LCD monitors developed to overcome the disadvantages of the old TN screen technology.
IPS screens include typical LCD components, but the difference of this screen is that the liquid crystal layers are now arranged in parallel rows with 2 layers of polarized glass above and below instead of square. corner. This change reduces the amount of scattered light, providing a wide viewing angle and better color reproduction .
Pros and cons of IPS and TN . screens
Although TN screens have been around for a long time and seem to be outdated, but this type of screen still has valuable advantages that IPS screens have not yet met.
The most typical is the very fast response speed , which can reach 1 ms and is considered much faster with today’s high-end IPS monitors. In addition, the TN screen also allows displaying images with a high refresh rate , up to 240 Hz , an unimaginable number compared to current IPS screen technology.
Although improved every year, but the biggest drawback on TN screens is still the narrow viewing angle , which means that the image will be distorted, become paler and harder to see if the user is not looking in the direction directly.
Meanwhile, IPS screens in general give wide viewing angles and the ability to ensure very good colors even when changing the viewing direction. In addition, the liquid crystal structure also helps the IPS screen to become durable, has a long life and better color retention than other types, especially without experiencing flash or screen burn when hand touch.
The biggest disadvantage of IPS screens is the high production cost and 15% more energy consumption than TN screens.
Summary table of advantages and disadvantages of IPS and TN screens:
| IPS screen | TN screen | |
| Advantage |
– Beautiful images, clear colors. – Wide viewing angle. – High brightness and contrast. – Does not light up when touched. – Long life. |
– Low production cost. – Low response time, very suitable for gamers. – Save electricity. |
| Defect |
– High production cost. – Consumes more electricity than TN. |
– Viewing angle is narrower than IPS. – The color if viewed at an angle is blurry and pale. |
How to identify a laptop with an IPS or TN screen
Based on the advantages and disadvantages listed above, we can easily identify which is the IPS screen laptop, which is the TN screen laptop.
The most accurate way to identify is the viewing angle , if you look at a screen and change the viewing angle from left to right, top to bottom and still don’t change much in sharpness, color, it’s really devices with IPS screens. On the contrary, if the color changes, the image becomes more blurred, lighter when changing the viewing angle, then it is indeed a TN screen.
In addition, you can also apply some additional detection tricks to have a more certain discriminant result such as: If your device has a light leak condition (light emitted from open corners on the device) ) then it is an IPS screen, or if the screen is touched and there is a light burn, it is a TN screen, and an IPS screen only has a slight color variation.
Should I choose IPS or TN?
If you have full financial conditions, when buying a laptop or an external monitor for a desktop computer, you should choose the IPS screen standard because this technology gives high advantages in color, definition and wide viewing angle. Suitable for you who specialize in graphics and entertainment.
If you don’t put much emphasis on display quality and cost optimization, TN screens are a more economical choice. This screen technology is quite suitable for those who specialize in games, requiring high refresh rate and response.
Thus, Tnhelearning.edu.vn has introduced you to the most basic information about the types of screens on laptops today. Hopefully, the above article will help you more in the future.
In conclusion, the IPS (In-Plane Switching) and TN (Twisted Nematic) screens found on laptops and computer screens have distinct differences in terms of their display quality, viewing angles, response time, and color reproduction.
The IPS screen technology offers several advantages over TN screens. Firstly, IPS displays provide more accurate and vibrant colors, making them ideal for tasks that require accurate color representation, such as graphic designing or photo editing. Secondly, IPS screens offer wider viewing angles, allowing the user to view the screen from various positions without experiencing any color shifts or loss of image quality. This makes IPS screens suitable for multimedia consumption or collaborative work. Lastly, IPS panels generally have a higher display resolution, resulting in crisper and more detailed visuals.
On the other hand, TN screens come with their own set of advantages. TN displays have faster response times, making them suitable for fast-paced gaming or other tasks that require quick screen refresh rates. They also tend to have lower input lag, resulting in minimal delay between the user’s actions and their appearance on the screen. Additionally, TN screens are often more affordable compared to IPS displays.
However, TN panels have some notable disadvantages. They have poorer color accuracy and limited viewing angles, which means that color shifts and image distortion can be observed when viewed from off-center angles. This makes TN screens less suitable for tasks that demand color precision or where multiple people may be looking at the screen simultaneously. Furthermore, TN displays may exhibit limited contrast levels and lesser overall brightness compared to IPS screens.
To recognize the type of screen on a laptop or computer, one can look for certain characteristics. IPS screens usually have more vibrant and accurate colors, wider viewing angles, and higher display resolutions. On the other hand, TN screens tend to have faster response times, lower input lag, and more affordable price points. Manufacturers often mention the screen technology specifications in the product descriptions or specifications, so referring to these details can also help in identifying the screen type.
In conclusion, the choice between IPS and TN screens ultimately depends on the intended usage and personal preferences. If color accuracy, wide viewing angles, and high-resolution visuals are important, then IPS screens are the better option. However, if fast response times and affordability are prioritized, TN screens may be more suitable.
