characteristic features of the in-plane switching ips lcd panel technology price

A type of LCD panel technology. In this type of panel, when no electric current is running through the liquid crystal cells, the cells naturally align in liquid crystal cells in a horizontal direction between two substrate panes of glass which blocks the transmission of light from the backlight. This renders the crystals opaque and results in a black display screen. When an electric current is applied, the liquid crystal cells are able rotate freely through 90° allowing light to pass through resulting in a white display screen. IPS panels have superior image quality, good contrast ratio and wide viewing angles of up to 178°. IPS panels are well suited for graphics design and other applications which require accurate and consistent color reproduction.

When shopping for a monitor you might come across the term IPS, short for “in-plane switching” to describe a certain type of display. So what does this term mean, and what benefits does an IPS display have over alternative technologies?

There are several different types of liquid crystal displays (LCDs), all of which use LED backlighting and are often referred to as “LED-LCD” displays. IPS panels are one such implementation and were designed to improve upon early twisted nematic (TN) models that suffered from poor viewing angles and color reproduction.

The term IPS is derived from the way the crystals are arranged inside the LCD. In an IPS panel, these crystals are aligned horizontally at all times and rotate parallel (in-plane) when voltage is applied. This allows light to pass through and for an image to be displayed on-screen.

While IPS panels are superior in some ways to other types of LCD panels, they are still bound by the limitations of the technology. Notably, LCDs must block out the backlight to display black which can often result in washed out or uneven blacks.

This prevents them from reaching the inky blacks that are possible with OLED displays, which are self-emissive. Some LCD displays use full-array local dimming to improve black reproduction, but this can result in unsightly “ghosting” or “blooming” around the edges of bright objects.

While IPS is a term that was coined by LG, a similar technology called PLS (Plane-to-Line Switching) behaves in much the same way but was designed by Samsung instead. Performance is similar enough that the term IPS may be used by some to refer to a PLS type display.

IPS displays offer the widest viewing angles of any LCD technology. This makes them ideal for use in televisions and monitors that will be viewed from any angle that isn’t face-on.

These panels also offer excellent color reproduction and deep blacks. For this reason, they are often favored by artists, photographers, and video editors. Keep in mind that buying an IPS display alone won’t get you truly accurate colors and that you will need to calibrate your display if you want to rely on it for accurate creative work.

These panels are often paired with bright backlights which deliver great peak brightness in HDR content, and good performance in bright sunlight. This is particularly true in conditions where glare is a problem since wide viewing angles allow you to change the angle of the screen (by tilting a laptop, for example) without sacrificing image quality.

For gamers, IPS displays generally offer faster response times than vertical alignment (VA) type displays. While once rare, high refresh rate IPS panels are now more common and affordable than they once were.

No technology is perfect, and IPS panels are no different. While these types of display offer the best color reproduction, they can’t match the contrast ratio seen on a VA-type panel. This is why many TVs use VA panels over IPS, a decision that sacrifices viewing angles for a richer image.

IPS panels are also generally more expensive than the alternatives since they’re more expensive to manufacture. Some fast VA panels aimed at gamers may cost more, but most are cheaper than your average IPS.

Finally, IPS panels may use more power than other similar technologies like TN. They use considerably more power than OLED displays, which are the most efficient types of display currently on sale.

IPS stands for in-plane switching, a type of LED (a form of LCD) display panel technology. IPS panels are characterized as having the best color and viewing angles among the other main types of display panels, TN(twisted nematic) and VA(vertical alignment). However, IPS panels are also the most expensive of the three.

When choosing a PC monitor, you may opt for an IPS panel because of its great image quality. Their best use case is professional (art, graphics et cetera) work. On the other hand, gaming monitor manufacturers tend to opt for TN panels because they"re the fastest of the three main LED panel types and are speedy. In fact, for a while it was rare to find an IPS panel with a refresh rate high enough for acceptable gaming (at least 75 Hz, although most gaming monitors offer at least 144 Hz). This is changing, but, again, comes at a premium in terms of price.

Note that some display may be labeled "IPS-level" or some other variant. This means that the panel was not made by LG and, therefore, the vendor isn"t allowed to call the display IPS. However, the technology and end results should appear the same to the naked eye.

IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, whilst remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s.

The TN method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down,Vertical Alignment (VA)—that could resolve these weaknesses and were applied to large computer monitor panels.

One approach patented in 1974 was to use inter-digitated electrodes on one glass substrate only to produce an electric field essentially parallel to the glass substrates.

After thorough analysis, details of advantageous molecular arrangements were filed in Germany by Guenter Baur et al. and patented in various countries including the US on 9 January 1990.Fraunhofer Society in Freiburg, where the inventors worked, assigned these patents to Merck KGaA, Darmstadt, Germany.

Shortly thereafter, Hitachi of Japan filed patents to improve this technology. A leader in this field was Katsumi Kondo, who worked at the Hitachi Research Center.thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.Super IPS). NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006.

IPS technology is widely used in panels for TVs, tablet computers, and smartphones. In particular, most IBM products was marketed as CCFL backlighting, and all Apple Inc. products marketed with the label backlighting since 2010.

Most panels also support true 8-bit-per-channel colour. These improvements came at the cost of a lower response time, initially about 50 ms. IPS panels were also extremely expensive.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In this case, both linear polarizing filters P and A have their axes of transmission in the same direction. To obtain the 90 degree twisted nematic structure of the LC layer between the two glass plates without an applied electric field (OFF state), the inner surfaces of the glass plates are treated to align the bordering LC molecules at a right angle. This molecular structure is practically the same as in TN LCDs. However, the arrangement of the electrodes e1 and e2 is different. Because they are in the same plane and on a single glass plate, they generate an electric field essentially parallel to this plate. The diagram is not to scale: the LC layer is only a few micrometers thick and so is very small compared with the distance between the electrodes.

The LC molecules have a positive dielectric anisotropy and align themselves with their long axis parallel to an applied electrical field. In the OFF state (shown on the left), entering light L1 becomes linearly polarized by polarizer P. The twisted nematic LC layer rotates the polarization axis of the passing light by 90 degrees, so that ideally no light passes through polarizer A. In the ON state, a sufficient voltage is applied between electrodes and a corresponding electrical field E is generated that realigns the LC molecules as shown on the right of the diagram. Here, light L2 can pass through polarizer A.

In practice, other schemes of implementation exist with a different structure of the LC molecules – for example without any twist in the OFF state. As both electrodes are on the same substrate, they take more space than TN matrix electrodes. This also reduces contrast and brightness.

Unlike TN LCDs, IPS panels do not lighten or show tailing when touched. This is important for touch-screen devices, such as smartphones and tablet computers.

Toward the end of 2010 Samsung Electronics introduced Super PLS (Plane-to-Line Switching) with the intent of providing an alternative to the popular IPS technology which is primarily manufactured by LG Display. It is an "IPS-type" panel technology, and is very similar in performance features, specs and characteristics to LG Display"s offering. Samsung adopted PLS panels instead of AMOLED panels, because in the past AMOLED panels had difficulties in realizing full HD resolution on mobile devices. PLS technology was Samsung"s wide-viewing angle LCD technology, similar to LG Display"s IPS technology.

In 2012 AU Optronics began investment in their own IPS-type technology, dubbed AHVA. This should not be confused with their long standing AMVA technology (which is a VA-type technology). Performance and specs remained very similar to LG Display"s IPS and Samsung"s PLS offerings. The first 144 Hz compatible IPS-type panels were produced in late 2014 (used first in early 2015) by AUO, beating Samsung and LG Display to providing high refresh rate IPS-type panels.

An acronym for In-Plane Switching, IPS is an LCD technology. Patented in the early 1990s, IPS was designed to overcome issues associated with TN TFT displays, such as limited viewing angles and low-quality color reproduction. To this day, IPS liquid-crystal screens are widely used in mid-range and high-end consumer electronics.

Unlike the previous generation of LCDs, IPS products don"t display aftertouch marks on the screen. Furthermore, IPS displays feature twice as many transistors per pixel and a more robust backlight than their predecessors. As a result, In-Plane Switching displays deliver bolder colors, which can be viewed from different angles.

First-generation IPS products faced three main shortcomings in comparison to TFT LCDs: higher energy consumption, higher prices, and slower response time. As companies such as Hitachi and LG have invested heavily in this technology, the response time was reduced in later IPS generations, and there have been further developments, such as improved color accuracy.

In 2010, a competing technology was introduced by Samsung. Available at a lower cost, the brand’s Super PLS (Plane-to-Line Switching) pledges to provide better image quality, more brightness, and an even greater viewing angle flexibility. Other competitors have entered the market since then, such as AU Optronics" AHVA (Advanced Hyper-Viewing Angle), which offers higher refresh rates.

IPS monitors are typically preferred by photographers, designers, editors, and other individuals who rely on color accuracy for their tasks. Price and power consumption, however, are still significantly higher for IPS technology, which makes TN TFT (twisted nematic thin-film transistor) LCDs still be attractive options.

When it comes to smartphones, the display choice stands between IPS, OLED, and AMOLED. Although there is no clear winner in this competition, each technology has advantages and disadvantages, which may help you choose your next phone. Generally speaking, OLED and AMOLED produce more vibrant colors and blacker-looking blacks, allow for the use of the always-on clock display feature, and are also more power-efficient. IPS displays, on the other hand, may provide more color accuracy, are not as pricey, and don"t pose the risk of display burn-in.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.

Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.

The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.

IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.

IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.

When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.

Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.

In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.

The greatest constraint of TN panel technology, however, is a narrower viewing angle as TN monitors experience more color shifting than other types of panels when being viewed at an angle.

Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.

TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.

Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.

These monitors also provide more visible details in shadows and highlights, making them ideal for enjoying videos and movies. They’re also a good fit for games focused on rich imagery (RPG games for example) rather than rapid speed (such as FPS games).

MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.

IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.

If you’re interested in learning more about IPS monitors, you can take a look at some of these professional monitors to see if they would be the right fit for you.

Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.

In-Plane Switching (IPS) was one of the first refinements to produce significant gains in the light-transmissive characteristics of TFT panels. Jointly developed by Hosiden and NEC, it is a technology that addresses the two main issues of a standard twisted nematic (TN) TFT display: colour and viewing angle.

With IPS, the crystals are aligned horizontally to the screen rather than vertically, and the electrical field is applied between each end of the crystal molecules – termed a lateral electric field. In this way, the crystals are kept parallel to the the electrode pair, and thus the glass substrate of the screen. The liquid crystal molecules are not anchored to the lower glass substrate, so move more freely into the desired alignment.

In a TN TFT display when one end of the liquid crystal is anchored to the lower glass substrate and a voltage is applied, the crystal compounds untwist, changing the angle of polarisation of the transmitted light. A downside of basic TN technology is that the alignment of molecules of liquid crystal alters the further away they are from the anchored electrode, turning at right angles to the substrates. This impairs the flow of light causing diminishing contrast, brightness and colour definition at wider angles to the screen.

IPS improves viewing angles of TFT monitors considerably, but means that two transistors are needed for every pixel, instead of the one needed for a TN TFT display. Using two transistors means that more of the transparent area of the display is blocked from light transmission, so brighter backlights must be used. The increased power consumption can make the displays unsuitable for notebook use, but in higher end, particularly multimedia focussed notebooks with widescreen movie viewing as a principle purpose IPS screens are employed. Wide angle viewing is certainly enjoyed, but the price is that battery life may be poor.

However, digital video and mobile TV has grown in popularity, and is of course commonly viewed on very small screen displays such as handheld cameras, mobile phones, handheld computers and PDAs. Since the size of these screens is so small, perhaps only 2 to 4 inches in width, front viewing isn’t possible for more than one person, so they need a wide angle of display. Although not the only solution employed, IPS has been adopted in many such devices, particulary by Hitachi who have consistently been one of the technology’s major adopters and innovators.

Since its introduction in 1996 IPS has gone through a number of advances, with stages of Super IPS, Advanced Super IPS, and IPS-Pro. The following table shows the improvements made in each development stage of the technology.

Super IPS was introduced in 1998 to combat the colour shift that was still apparent in wide angles of the original IPS screens. With AS-IPS the breakthrough was to move from opaque to transparent electrodes, considerably reducing the amount of power required for an IPS backlight. Also notice the transition to more smooth pixels, giving a cleaner, crisper more continuous image at all angles.

IPS-Pro is highly advanced and very expensive, only used in industrial settings where image clarity on a screen is considered critical. Commonly IPS-Pro is used in medical settings, particularly in surgery, but there are other uses in advanced engineering and science that benefit from the clarity and precision of IPS-Pro.

At the China International Display Industry Conference in 2018, JDI (Japan Display Inc) presented an “Introduction of JDI’s Latest Technology” speech and showed the picture below:

In this figure, the chart shows the trend of share in LCD (Liquid Crystal Display ) display technologies. JDI had a strong advantage in IPS technology because Hitachi, one of JDI main shareholders, is the company that initially developed IPS technology. Now we often see this word within display glossary or product specification. So, what is IPS?

IPS stands for In-Plane Switching. The name carries the implication of how the technology works by switching the liquid crystal molecules in only one plane.

Figure 2 (below) can help us to understand it a little better. On the left is the conventional LCD and on the right is the IPS technology LCD. The LC (Liquid Crystal molecule, same as below) in the LCD will change the direction following the electrode voltage. Conventional LCD’s LC switch with free angle including vertical and horizontal. But IPS" LC switch on horizontal plane only and the long axis of LC is always parallel to the substrate.

There is another difference in Figure 2 as well. In order to ensure the LC switching is only on one plane, the positive and negative electrodes are placed on the lower substrate. In conventional LCDs, they are placed on the on upper and lower substrate separately.

IPS is normally black without power and the light transmission is controlled by the electrode that is vertical with LC long axis. Higher voltage creates a sharper LC switching angle and thus lets more light through.

The most improvement of IPS technology is that it corrects the difference of view angle of conventional LCD screens. In Figure 3 (below), the projection size doesn"t change proportionally to the change in angle in traditional LCDs. The brightness is also not the same because of the phase delay and light transmission difference.

The LC of IPS LCD is horizontal, so the projection size is the same and there is not a brightness difference even you watch from a different direction. It is a fundamental solution to view direction differences that enlarges the viewing angle at the same time.

There are many other advantages of IPS. Some of note are the better color expression and higher contrast ratio is very high on static status because the switch angle can be controlled by voltage accurately.

Because LC is on a certain plane, the rippled area is small and it recovers quickly if the surface is pressed. For this reason, IPS LCDs have the popular name of “Hard Screen."

IPS does have some disadvantages. The Aperture Ratio is low and affects the light transmission as the positive and negative electrode both placed on the lower substrate. There is also a need for a brighter backlight and more power required for driving the LC switching.

There have been many subsequent technology developments on top of the IPS base that have different characteristics, advantages, and disadvantages. The tend to have different viewing angles, brightness, contrast ratio and color saturation levels. They also come in at varying costs. Since they tend to be quite different in character, it"s important to evaluate them on their own merits and not treat them as the same technology. In a subsequent article, we will discuss some of the different technologies and some of the advantages that each bring.

Display technology has been evolving for more than a century and continues to drive innovations in the electronic device market. IPS technology was developed in the 90s to solve color and viewing angle issues.

IPS display panels deliver the best colors and viewing angles compared to other popular display planes, including VA (vertical alignment) and TN (twisted nematic).

LCDs (liquid crystal displays). IPS changes the behavior of an LCD’s liquid crystals to produce a sharper, more accurate picture. This technique allows IPS displays to deliver a higher quality viewing experience than other screen types like TN or VA.

IPS acts on the liquid crystals inside an LCD, so when voltage is applied, the crystals rotate parallel (or in-plane), allowing light to pass through them easily. By reducing the amount of interference in the light being produced by the display, the final image on the screen will be much clearer.

One of the leading advantages that IPS offer is its ability to deliver wide angles while preserving colors and contrast. This means you can view an IPS screen from nearly any angle and get an accurate representation of the image on-screen.

IPS display screens and monitors offer the best quality in different environments (direct sunlight, low light, indoors, or outdoors) compared to TNs or VAs.

IPS LCDs require about 15% more power than a standard TN LCD. OLED displays require much less power than IPS types due to the fact that they don’t require a backlight. The LCD IPS technology is not the ideal solution if you need an energy-efficient display. You’re better off choosing an OLED or TN TFT for a low-power solution.

Because of the newer and more advanced technology found in IPS displays, they’re more expensive to manufacture. For a more cost-effective solution, a TN LCD would be a better choice.

IPS displays provide a huge boost to viewing angles and color reproduction, but they don’t have the same contrast capabilities as some other competing display types. OLED displays are able to deliver true black by shutting off their active pixels completely, resulting in much higher contrast than IPS displays. If you’re looking for maximum contrast in your display, you’re better off with an OLED display.

Because of in-plane switching’s ability to boost viewing angles and retain color accuracy, it allows LCDs to compete with the high contrast images found on OLED displays.

If you don’t require the highest refresh rates and don’t mind slightly higher power consumption, then an IPS display will greatly benefit your project.

Twisted nematic effect was a breakthrough LCD technology that became dominant during the 1980s and 1990s. However, TN panels suffered from several limitations and the disadvantages of TN display technology restricted the applications of LCD.

Nonetheless, the introduction of in-plane switching or IPS during the mid 1990s and its mass popularity in mid 2000s marked another breakthrough in LCD technology. IPS display technology has expanded the application of LCD to include high-definition television and computer monitors, as well as high-resolution mobile devices such as smartphones and tablets.

This article lists down and describes the advantages and disadvantages of in-plane switching display technology, thus also discussing the strengths and limitations or drawbacks of IPS LCD panels.

One of the notable advantages of IPS LCD panels over TN panels is color reproduction that further translates into color accuracy and better image quality.

Note that a typical TN panel only has a 6-bit RGB color depth. This means that it is only capable of producing 262,144 possible colors. On the other hand, a conventional IPS has an 8-bit RGB color depth capable of producing 16.7 million possible colors.

Though another type of LCD technology called virtual alignment or VA has a similar 8-bit RGB color depth, several manufacturers have introduce high-end IPS panels with 16-bit to 24-bit RGB color depth.

Active-matrix organic light-emitting diode or AMOLED display technology is a close competitor of IPS display technology. Between the two however, IPS has better color accuracy because AMOLED panels are prone to producing images with strong or highly saturated colors.

When compared against TN panels and VA panels, as well as AMOLED panels thereby, IPS LCD panels produce more vibrant images and more realistic colors. This advantage means that in-plane switching is an ideal display option for use in multimedia consumption, as well as in color critical work such as photo editing, graphic design, and video editing.

TN panels also suffer from very limited viewing angle as demonstrated by poor off-axis image quality. The introduction of VA LCD technology tried to resolve this limitation. But VA panels suffer from color shifts when viewed from a slightly different angle.

Nonetheless, wide viewing angle is another advantage of in-plane switching over TN and VA display technologies. Typical IPS LCD panels will produce no image distortion and relatively minimal color shifts when viewed from different angles while high-end IPS panels will display consistent contrast and brightness levels under different viewing angles.

This advantage of IPS panels is made possible because the technology involves the capacity to change the physical behavior of the liquid crystal layer by making the crystal molecules respond to the electric field in parallel to the TFT. This also results in better color reproduction.

For smartphone and tablet applications, the aforementioned advantage means that these portable devices can be held in various angles and eye levels. This advantage also means that television sets or computer monitors with IPS panels offer a better visual experience than other LCD panels.

Colors and images on an IPS panel remain considerably more visible under bright outdoor lights or direct sunlight than other display technologies. This is an advantage of in-plane switching technology over TN and AMOLED display technologies.

The better color reproduction coupled with better viewing angle and backlighting make IPS usable or viewable under direct sunlight. Note that TN panels suffer from poor visibility under direct sunlight because of its limited color depth. AMOLED panels, on the other hand, have similar problems because of the inapplicability of backlighting.

Dead pixels are an inherent issue affecting different LCD technologies. The lifespan of IPS LCD panels cannot be generally compared against the lifespan of TN panels or VA panels.

However, it is important to note that TN display technology is easier to implement and thus, TN panels are easier to produce. This further translates to more manufacturers producing TN panels, thereby increasing the tendency for low manufacturing standards. Some manufacturers are also producing low-end TN panels to meet demands for cheaper LCD.

When generally compared against typical TN panels nonetheless, IPS panels might have a longer lifespan. On the other hand, the lifespan of VA panels might be comparable with IPS. Of course, it is important to remember that this is an overstatement.

Compared to AMOLED panels however, IPS panels have obvious longer lifespan. Remember that one of the notable limitations of AMOLED is its susceptibility to noticeable pixel degradation and faster screen burn-ins.

When compared to TN panels, IPS LCD panels have better contrast ratio because it has better color depth. However, VA panels and AMOLED panels have better contrast ratio than IPS panels.

Backlighting can be blocked effectively in a vertical alignment display technology. This produces deeper blacks and subsequently, higher contrast ratio compared to in-plane switching display technology.

On the other hand, AMOLED panels naturally produce deep blacks because they represent the absence of light and thus, the absence of color. This results in higher contrast ratio. Although IPS technology produces intense whites, high-end AMOLED panels can also rival typical IPS panels in this regard.

Another disadvantage of IPS panels when compared against TN panels and AMOLED panels is power consumption. In-plane switching technology consumers more power than TN or AMOLED display technologies.

Note that TN panels are suitable for battery-operated and low-powered devices. On the other hand, a typical IPS panel requires 15 percent more power than a TN panel. IPS panels also require a strong backlighting to improve display clarity unlike AMOLED panels.

This drawback means that consumer electronic devices featuring an IPS panel have more power requirements than counterpart devices equipped with TN or AMOLED panels. This affects the overall energy efficiency rating and battery life performance of a specific device.

Other disadvantages of in-plane switching technology are slow pixel response time and low refresh rate. The response time and refresh rate of IPS panels are slower and lower than TN or AMOLED panels.

Pixel response time is the duration it takes a single pixel to transition from one state to another. Refresh rate is the frequency in which the image in a display is refreshed. Slow pixel response time and low refresh rate create ghosting effects and motion blurs around a moving image. In addition, both ghosting effects and motion blurs are more straining to the eyes.

This limitation makes an IPS panel an unsuitable display option for use in fast-paced and competitive gaming. TN display technology has the faster response time and higher refresh rates among existing LCD technologies. This is the reason why some hardcore gamers still prefer TN panels to IPS or VA panels despite having poor color reproduction.

Manufacturers have produced IPS panels with better response times and refresh rates. However, these panels are more expansive than TN panels, thus making them unappealing to budget-conscious consumers.

Manufacturing IPS LCD panels is costlier than manufacturing TN panels because of the involved engineering complexity. This higher manufacturing costs results in higher prices for end consumers.

Entry-level laptops such as netbooks, as well as feature phones and budget smartphones are commonly equipped with TN panels. Devices with IPS LCD panels are relatively more expensive. Note that high-grade IPS panels are featured in top-of-the-line products with higher price tags.

Between in-plane switching and AMOLED display technologies however, both are also costly to manufacture and both IPS and AMOLED panels are commonly featured in premium products such as high-end smartphones and tablet computers.

From the aforementioned, in-planed switching display technology outperforms other LCD technologies to includw twisted nematic and vertical alignment. The strengths or advantages of IPS LCD panels center on better image production and visual performance stemming from having higher color depth, more accurate color reproduction wider viewing angle, and better visibility under direct sunlight.

Nonetheless, the drawbacks and disadvantages of IPS LCD panels make them unappealing to some extent. They are not as power efficient as TN or AMOLED panels. They are not as inexpensive or as readily accessible as TN panels as well. These disadvantages translate to the limited applications of in-plane switching technology when cost or price and power consumption are factored in.

IPS is an acronym for in-plane switching, which is a screen technology that is used with LCD screens. In-plane switching was designed to address limitations in the LCD screens of the late 1980s that used a twisted nematic field effect matrix. The TN method was the only technology available at the time for active matrix TFT (Thin Film Transistor) LCDs. The main limitations of the twisted nematic field effect matrix LCDs are low-quality color and a narrow viewing angle. IPS-LCDs deliver better color reproduction and wider viewing angles.

IPS-LCDs are commonly used on midrange and high-end smartphones and portable devices. All Retina Display Apple iPhones feature IPS-LCDs, as does the Motorola Droid and some TVs and tablets.

IPS-LCDs feature two transistors for each pixel, whereas TFT-LCDs use just one. This requires a more powerful backlight, which delivers more accurate colors and lets the screen be viewed from a wider angle.

IPS-LCDs don"t show when the screen has been touched, which you might notice in some older monitors. This is particularly advantageous for touch-screen displays like those on smartphones and touch-screen laptops.

The downside is that an IPS-LCD consumes more power than a TFT-LCD, possibly up to 15 percent more. They"re also more expensive to make and have longer response times.

Enhanced IPS (E-IPS) improved the viewing angle and reduced the response time to five milliseconds, while also widening the aperture for light transmission. It was released in 2009.

2010 saw Professional IPS (P-IPS), which offered more than a billion colors and more orientations per pixel. IPS-Pro is highly advanced and expensive.

LG Display released Advanced High-Performance IPS (AH-IPS) in 2011 to improve color accuracy, increase the resolution, and provide more light when in lower power mode.

Samsung introduced Super PLS (Plane-to-Line Switching) in 2010 as an alternative to IPS. It"s similar to IPS but with the added benefits of a better viewing angle, a brightness increase of 10 percent, a flexible panel, better image quality, and a 15 percent lower cost than IPS-LCDs.

In 2012, AHVA (Advanced Hyper-Viewing Angle) was introduced by AU Optronics to provide an IPS alternative that featured IPS-like panels but with higher refresh rates.

IPS or In-Plane Switching technology provides a wide 178°/178° viewing angle, so users see impressive images with consistent color and image quality from virtually any angle.

What is an IPS monitor? An IPS monitor is an LCD computer display that uses In-Plane Switching (IPS) technology rather than Twisted Nematic (TN) or Vertical Alignment (VA) technology to illuminate pixels. This is advantageous to those who work with color since IPS technology allows for a new level of color accuracy and consistency and minimizes color shift/contrast issues that face other monitors.

Color remains consistent no matter what angle a user views an IPS monitor from. The result is clearer and crisper images with vibrant colors, resulting in a better viewer experience.

Are you shopping for a new monitor? If you encountered the different types of panels, are you curious about what is IPS ( In-plane switching ) monitor? If you suddenly become overwhelmed by the many display technologies available in the market, then this guide is for you.

If you are buying a computer monitor, do not just rely on the size (see a 23.8-inch monitor) and screen resolution, check out all monitor types. In case you have not heard of anti aliasing methods, click here. These days, you must also pick the display technology that best fits your requirements and protects your eyes while enabling great refresh rates of up to 240Hz for maximum viewing pleasure, with speakers or without. Also, what about the monitor response time? Check out our findings about that.

One popular monitor panel technology type is IPS screen, which refers to "in-plane switching." This kind of IPS panel is embedded with LCDs (liquid-crystal displays) as well as modern smartphones and computer monitors, from lower budget ones to freesync models.

IPS technology is usually featured in higher-end gadgets as a powerful tool to give consistent colors regardless of angle, so expect to find newer phones or the best 40 inch 4K screens to have IPS display. Also, is 1440p resolution 4K too? That"s another hot topic.

Other "IPS-type" panels exist - they are PLS (plane-to-line switching, S-IPS, H-IPS, P-IPS and e-IPS). All of them are characterized with outstanding color and wide viewing angles.

IPS monitors are preferred by those in the art profession (such as graphic designers, cartoonists or photographers) simply because this technology prioritizes accurate color reproduction, color accuracy, sufficient response times, and maximum viewing angles available. You can also find out what monitor panel type is better in our OLED vs LEDreview.

For artists, one major benefit of using IPS monitors is that because IPS is able to display more colors, they completely support professional color technologies, such as Adobe"s RGB. They aren"t even expensive - pro artists could easily invest in an monitor under $200.

Response time used to be an issue with an IPS gaming monitor, which is why experts recommend serious and competitive gamers to consider another type of monitor panel since this one is infamous for having blurred images - in motion in the past.

Of course, the pixel response times of IPS monitors is a highly debatable topic and these claims could vary on a case-to-case basis. And since the monitor technology has improved through the years, you might even have no issues with lagging response time - see Dell SE2717HR for affordable gaming monitor or Dell UltraSharp U2720Q.

In-Plane Switching (IPS) panel technology was developed by Hitachi in the mid-90s as a way to address the color inaccuracies or lack of viewing angles provided by the more traditional TN (twisted nematic) panels. We covered IPS vs TN in depth.

With over a decade now in the market, you have to understand that different companies may add something to their own product, so it is impossible to compare two smartphones with IPS display technology from two competing brands. The IPS backbone may be the same, but the image quality of a phone"s display is not only about whether it uses IPS LCD or not.

In addition, IPS panels could be used by a particular brand, but not disclosed as "IPS." This is because IPS technology can fall under different names, such as "Super-IPS" (S-IPS), "Advanced Super-IPS," "Enhanced S-IPS", "Super TFT" and so on.

Apple - When the late Steve Jobs unveiled the long-awaited iPad in 2009, the 9.7-inch tablet used IPS LCD. This update came with the release of iPhone 4 in June 2010.

Samsung - The company uses the term “PLS” or “plane-to-line switching” when referring to their IPS models - check out also Samsung"s Quantum Dot vs. IPS post.

Lenovo - If you"re a fan of Lenovo,you know that Lenovo"s ThinkPad X Series Laptops were designed with IPS tech to provide 180-degree wide-screen viewing. Other Lenovo products equipped with IPS tech include the Thinkvision, IdeaTab, Yoga, ThinkPad and Lenovo Miix 2 tablet series.

LG - This company has introduced IPS screens for many of its computer monitors and television units (see best LG monitors here), promising its users that the "LG IPS tech solution will get you ready for true-to-life colors, deep black levels and rich colors for amazing contrast and color."
