You are viewing the article How are IPS and TN screens on laptops and computer screens different? Advantages and disadvantages and how to recognize at daotaomt.edu.vn you can quickly access the necessary information in the table of contents of the article below.
IPS (In-Plane Switching) and TN (Twisted Nematic) are two different types of LCD (Liquid Crystal Display) technologies widely used in laptops and computer screens. These screen technologies have significant differences in terms of image quality, color reproduction, viewing angles, response time, and cost. It is essential to understand the advantages and disadvantages of each screen type to make an informed decision when purchasing a laptop or computer screen. In this article, we will explore the disparities between IPS and TN screens, discuss their respective advantages and disadvantages, and provide guidelines on how to recognize each screen type.
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Although TN screens have been around for a long time and seem to be outdated, but this type of screen still has valuable advantages that IPS screens have not yet met.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, Daotaomt.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, IPS (In-Plane Switching) and TN (Twisted Nematic) screens are two distinct technologies used in laptops and computer screens, each offering its own set of advantages and disadvantages.
Starting with the differences, IPS displays boast superior color accuracy, wider viewing angles, and better overall image quality. This is due to the liquid crystals in an IPS screen rotating parallel to the display, allowing light to pass straight through. On the other hand, TN panels have limited viewing angles and tend to wash out or distort colors when viewed from the side. TN screens have liquid crystals that rotate perpendicular to the display, which can restrict the amount of light that passes through.
In terms of advantages, IPS screens are particularly suitable for professionals and enthusiasts who require accurate color reproduction, such as graphic designers, photographers, and video editors. The wider viewing angles also make IPS screens ideal for collaborative work or sharing content with others. Additionally, IPS screens generally have better contrast and black levels, resulting in more vibrant and detailed images.
On the other hand, TN screens offer a few advantages of their own. These screens typically have faster response times, making them suitable for gaming or other fast-paced applications where motion blur is a concern. TN panels also tend to be more affordable and consume less power than IPS panels, making them a more budget-friendly option for many users.
To recognize the type of screen on a laptop or computer, certain visual cues can help. IPS screens will usually showcase better color reproduction with more accurate and vibrant colors, as well as wider viewing angles that maintain image quality from various positions. TN screens, on the other hand, may exhibit washed-out colors, especially when viewed off-center, and narrower viewing angles. It is worth noting that some manufacturers may label their products explicitly as having either IPS or TN screens.
In conclusion, the choice between IPS and TN screens depends on the specific needs and preferences of the user. IPS panels offer superior color accuracy and wider viewing angles, making them favorable for professional tasks that demand precise color reproduction. On the other hand, TN screens excel in fast-paced applications and tend to be more budget-friendly. By considering the advantages and disadvantages of each technology, users can make an informed decision when selecting a laptop or computer screen that suits their requirements.
