The 5 Main Advantages of IPS Technology

We have already had the opportunity to introduce IPS (In-Plane Switching) technology, talking about the screens of smartphones, televisions, and monitors. The time has come to investigate the topic, to understand what the advantages of using this LCD technology are.

IPS panels have existed for a long time; but they were used, so far, in the professional field (and in particular photographic), for their ability to reproduce colors as faithfully as possible, as well as brilliance and contrast.

Now, LG has included this technology in most of its products (in addition to the aforementioned monitors and smartphones, also for digital signage ) to offer the best image quality. How?

LG IPS

Here are the five main advantages of using IPS.

1. More real colors

More brilliance and contrast (combined with uniform color temperatures) allow you not to lose any image detail. So much that it will seem real: the colors are so similar to the real ones that you will have the feeling of experiencing the film or the program in the first person.

2. Color calibration

LG Display, a company that is part of the LG Electronics group, is the division that deals with the production of screens for all LG products. And that has developed color calibration tests to ensure a more accurate rendering.

3. Greater viewing angle: up to 178ยบ

IPS technology allows you to see the best image from any angle, up to 178 degrees (horizontally but also vertically). Whether you are standing, sitting or lying down, you will not perceive any change in color or loss of parts of the image. This makes the difference, especially when you find yourself in front of the canvas (and friends will queue up to watch the game or the X-Factor final from you).

4. Prevents eye strain

IPS technology allows you to reproduce an image with more details: this helps to avoid eye fatigue. Even the continuous and very rapid refresh of the images allows a more comfortable vision, even of action films and sports shows.

5. Savings

IPS is an ECO-Friendly technology: the light is emitted through high-efficiency LEDs, which allow to considerably reduce energy consumption.

What Do IPS Mean?

IPS is an English acronym meaning In-Plane Switching, literally ” variation in the plan “.

It refers to the technology with which some of the best PC monitors currently available are built.

In fact, compared to a TN panel, an IPS panel has liquid crystals arranged horizontally with respect to the panel surface. The basic operation is the same as in other LCD screens: what changes is the way the crystals react to the current.

In fact, subject to the action of an electric field, the liquid crystals rotate on themselves, but always remaining parallel to the panel.

Presented with the real novelty of LCD screens after the introduction of TN panels, IPS technology managed to overcome their problems.

In fact, IPS monitors have undeniable advantages:

  • greater brilliance and color definition;
  • much wider viewing angles.

These two features, combined with greater black density and color rendering, make IPS panels perfect for professional graphic applications.

Not only that, but IPS are also the displays of many TVs and the screens of most smartphones on the market today.

However, the parallel arrangement of the liquid crystals impairs the reactivity in the rotation of the crystals on themselves. Here are the main defects of IPS monitors:

  • Response times on average higher than a TN monitor
  • low refresh rates, in fact often fixed at 60 Hz
  • higher cost with the same specifications.

In recent years, IPS technology has evolved and it is not difficult to find IPS monitors with high refresh rates and low response times. But the cost goes up accordingly.

Android from A to Z: What is an IPS Screen?

IPS stands for In-Plane Switching.

It is a technology used in the realization of LCD displays that solves some limitations of the previous TN (Twisted Nematic) technology, in particular with regards to viewing angles and fidelity in color reproduction.

In the IPS screens, the liquid crystal molecules move parallel to the panel and not perpendicularly, and this allows viewing angles close to the flat angle, with a consistent and accurate color rendering. To have a demonstration of the goodness of IPS technology, you can refer to a comparison made by Japan Display with TN technology.

Initially, IPS panels were very expensive and intended only for high-end monitors, but over time they have become widespread in the consumer market. In the mobile environment, and in general in touch-based devices, IPS panels were immediately highly appreciated also because they do not lighten or otherwise change the image rendering when touched.

Among the defects of the IPS technology, apart from the price, there were, in particular, the greater response times and the higher energy expenditure than the TN, both problems largely overcome, even if in the gaming field there are still those who prefer the latter, in the light of the fastest response.

What is IPS?

IPS, also known as In-Plane Switching, is a type of screen and vision technology.

Specifically, an IPS panel is a type of TFT LCD (or “active matrix” LCD). LCD, or liquid crystal display, indicates the use of light-modulating properties from unlit liquid crystals to produce flat panels or electronic screens. TFT, which means Thin Film Transistor, is a variant of the LCD monitor created and marketed for its properties of color enhancement, contrast, and black levels. The two most common types of LCD TFTs are the IPS and TN screens.

The TFT LCD screen (IPS monitor with active matrix) was developed by Hitachi in 1996 as a solution to the limits of the late 80s LCD TFT (Twisted Nematic) LCDs, not standard IPS LCDs. The TN screen is known for its viewing angle limitations, such as inversion of colors at extreme angles and low color quality. In contrast, IPS monitors provide wider viewing angles and higher quality color reproduction by making pixels parallel, rather than perpendicular. In an IPS display, the liquid crystals are parallel to the panels when they receive energy. In a TN screen, the crystals are oriented perpendicular to the upper part of the panel. High-performance tablets and smartphones use IPS vision technology because they are often used to view movies, make video chats and store photos. A better viewing angle and color characteristics guarantee better user experience. Creativity professionals benefit from the use of an IPS screen because an IPS LCD with a wider color gamut and wider viewing angles allows for greater aesthetic accuracy and therefore excellent quality.

Other versions of IPS include the following technologies:

  • Super TFT (IPS) for a wider viewing angle
  • Super-IPS (S-IPS) to eliminate the effect of changing colors and improve the pixel refresh rate.
  • Advanced Super-IPS (AS-IPS) for high transmittance
  • Enhanced IPS (E-IPS) for better diagonal viewing angle and reduced response time
  • Horizontal IPS (H-IPS) for an improved contrast ratio and an Advanced True White polarizing film that creates a more natural white color
  • Professional IPS (P-IPS) for true color depth

Is IPS suited to my needs?

An IPS monitor, also known as the In-Plane Switching panel, uses a type of high-quality vision technology typically used in high-performance computer, laptop, tablet, and smartphone screens. IPS offers a better user experience thanks to the wider angle and better color quality, as well as display features evolved over time compared to the introduction of TN effect LCD screens, used a lot in the 90s.

To decide if an IPS monitor is the best choice for your needs, first understand the TFT LCD vision technology. LCD TFT stands for “Liquid Crystal Display” and “Thin Film Transistor” (thin-film transistor). The LCD screen is composed of polarizing material and liquid crystals. TFT LCDs, also known as “an active-matrix “, were born as a variant of LCDs. TFT LCDs improve the color, contrast and response times of passive matrix LCDs.

The two most common types of LCD TFTs are the IPS LCD TFT and TN LCD TFT screens. TNs usually have a faster response time, which guarantees better entertainment experiences for those who watch sports or play video games, but IPS was born to solve TN screen problems, such as reduced viewing angle and the low quality of color reproduction. If you use your laptop or smartphone for creative activities, watching movies and videos, video chatting or uploading photo albums, you should choose an IPS, which gives you the best viewing angle and maximum color accuracy.

What are the qualities of IPS compared to TFT?

IPS (In-Plane Switching) is one of the most common types of TFT LCD screens. The TFT LCD screen improves the image quality of a normal LCD screen thanks to thin-film transistor technology. The IPS LCD screen, a variant of the TFT LCD (active matrix) improves the screen technology ensuring better color reproduction and a wider and more precise viewing angle. TFT LCD IPS technology is widely used for desktop and laptop computers, tablets and smartphones with high performance.

LCD stands for Liquid Crystal Display. It is a type of thin screen that forms a luminous panel display using two layers of polarized panels and a liquid crystal solution. Light is projected through liquid crystals to produce an image, but since liquid crystals are not illuminated, they need a backlight.

TFT LCDs (also known as active matrix LCDs) were created to improve colors, contrast and response time in LCD screens. The two most common types of LCD TFTs are the TFT TN LCDs (not standard IPS) and the IPS TFT LCDs. A monitor with an IPS screen offers improved features such as optimal viewing angles, precise colors, invariable color reproduction, and reduced energy consumption. In summary, IPS is a variant of the TFT LCD that improves the technological limits of TN panels, ie reduced viewing angles and color reproduction.
