IGZO VS IPS Display – Real Differences?

Do you wonder what prestige IGZO and IPS possess in today’s display industry? Well, no need to get mislaid in these symbols because you’ll be learning them in a more clear way here. The significance of IGZO & IPS can be determined by analyzing their properties and potency for display quality. Moreover, you will find the exact difference between the two.


The price & quality trade-off applies to screens and monitors like any other product on the market. Some technologies are fundamentally better while also being more expensive. IPS is among them.

IGZO, which stands for Indium Gallium Zinc Oxide, is a different kind of semiconductor found in the TFT backplane. An IGZO-TFT IPS panel significantly reduces power consumption compared to aSi-TFT IPS screens while providing equally accurate and bright colors.

To dispel any confusion, IGZO, a different transistor in the TFT (thin-film-transistor) backplane, is not a simple panel. So, it can be used in TN, VA, IPS and even OLED screens, among other types of panels

Let’s talk over it further here;

What is an IPS Panel Exactly?

An IPS panel is found in every premium LCD. All of Apple’s renowned “Retina” displays have IPS panels as well. In-plane switching is referred to as IPS. The color rendition of this technology is superior to that of the conventional twisted nematic (TN) LCD panels from the 1980s, and there is essentially no color shift at oblique viewing angles.

One of the four varieties of panel displays is the IPS. The TN, VA, and OLED are the other three. The IPS are renowned for their superb contrast. It is famous for its color consistency and accuracy as well.

Individuals who enjoy graphics will find this panel to be great. Wide viewing angles and a quick response time are only two of the incredible qualities of the IPS.

It’s true that TN still has the fastest response speeds, but newer versions with IPS displays may achieve response rates of approximately one millisecond. Although AH-IPS (the most recent iteration of IPS technology) panels are significantly more expensive, the color fidelity and PPI (pixels per inch, a measure of pixel density) are far better.

Si- IPS (Amorphous Silicon TFT IPS Panels)

Most high-end LCDs employ IPS (in-plane switching) panels because they can produce the most precise and consistent color reproduction together with ideal viewing angles.

The most recent advancements in IPS panel technology are LG’s AH-IPS and Nano IPS panels, which provide even more accurate color reproduction and quicker response times. At the same time, IPS Black boosts the contrast ratio.

What Exactly is the IGZO-TFT-IPS Panel?


The abbreviation “IGZO”  stands for indium gallium zinc oxide. Contrary to the amorphous silicon utilized in every other monitor, IGZO is not a panel type but a unique semiconductor. Since IGZO has significantly higher electron mobility than silicon, it is advantageous for usage in the TFT backplane of all panels, including TN, IPS, and even OLED.

As a result, IGZO is perfect for panels with larger pixel densities since it offers significantly improved color reproduction while enhancing the panel’s power economy. Plus, IGZO may be made transparent, resulting in some truly premium transparent displays when used in conjunction with OLED.

Additionally, the IGZO’s speed means refresh rates would be perfect for video games. Samsung and Sharp received licenses to use the compound semiconductor known as IGZO (Indium Gallium Zinc Oxide). However, Sharp was the company to introduce IGZO into 32-inch LCDs, smartphones, and tablets.

The IGZO transistor is expensive since it is made of rare metals like indium and gallium. For instance, the NEC PA322UHD is a 4K resolution monitor that covers 99.2% of the Adobe RGB color palette and has a 14-bit Look-Up Table for exact calibration. It costs about $3000 and has an IGZO-TFT IPS panel.

There are also several less expensive IGZO displays available, such as the AOC 24G2, a well-liked and affordable 1080p 144Hz IPS gaming monitor.

What is IGZO TFT ( Thin-Film-Transistor)?

It is an abbreviation for a thin-film transistor, simply a particular kind of liquid crystal display (LCD). It uses TFT technology, which provides greater image quality. Its design is more akin to an active matrix LCD. TFT can be found in many devices and appliances with screens. Even certain car parts contain them.

Why is IGZO-TFT IPS Valuable? 

You must be thinking if this development is important for your viewing experience, given the number of breakthroughs in the display business. Comparing the IGZO-TFT IPS advancements to those of the aSi-TFT IPS displays is the best way to do so.

One of the first iterations of the TFT IPS transistors is the aSi-TFT. It resembles the IGZO in many ways, but the key distinction is that it requires much more power to produce backlighting of the same caliber as the latter. For those looking to cut their electrical costs, this is a big no-no.

IGZO VS IPS Displays

The primary benefit of IGZO at the time was its extremely low power consumption compared to IPS displays. Because of the greater electron mobility, which is 20–50 times quicker than a typical panel, IGZO can be up to 80%–90% more power efficient than a traditional a-Si IPS panel display.

Secondly, IGZO delivers a fast response time, greater color performance, and higher pixel density capacity. In contrast to a-Si panel monitors, which need more power to backlight displays with higher pixel densities, IGZO does not. It can produce even brighter images with significantly less energy.

This works well for mobile devices with lots of pixels. Regardless of the panel size, IGZO can give greater display resolution, speed, and pixel density. Consequently, one of the prototypes had a 6-inch IPS screen with a 2560 x 1600 resolution or 498 pixels per inch.

What Makes IGZO Futuristic?

OLED panels will benefit more from the IGZO implementation because they have a similar special capability. Both of them can be made transparent. Additionally, the intermittent conductor would simulate writing on paper on the ultra-sensitive write IGZO displays.

Even while the pricing gap between the IGZO-TFT and a-Si-TFT IPS panels may make the difference between them insignificant for now, IGZO will undoubtedly make a significant contribution to the advancement of displays in the future.

High-quality touch-sensitive transparent displays are becoming a reality faster and faster because they can significantly lower power consumption while providing remarkable pixel density, resolution, and speed.

It will take some time before this technology is affordable and widely accessible because it is still rather new and little used.

Major Perks of IGZO-TFT IPS Display

1. Less Power Consumption

Power consumption is the IGZO-TFT IPS’ first benefit. Power usage is a major concern for many people, given the current state of the climate change debate and the fact that electricity prices aren’t declining year after year.

Thankfully, there is an improved version of the aSi-TFT IPS called the IGZO-TFT IPS. With a major boost in efficiency alone, the IGZO is at least 80% more effective than its predecessor. The increased electron mobility explains this effectiveness.

2. Higher Pixel Density

The greater pixel density of the IGZO is another benefit. Each inch of the screen has more pixels with more accurate and vivid colors when the pixel density is increased. You essentially receive a high-quality display. This system’s ability to produce better-quality photos while using less energy is astounding.

3. Rapid Response Time & Refresh Rate 

Additionally, IGZO offers quicker reaction and refresh rates. It possesses all the qualities you require to improve your performance in combat and racing games.

4. Better Sensitivity

Moreover, the reduced noise from IGZO semiconductors results in better sensitivity on touch-sensitive devices. Drawing or writing on an OLED iPad mini or iPad pro with an IGZO backplane seems more realistic and satisfying.

Here are a few factors to consider when buying an IGZO display.

Consider Your Budget First

IGZO is, exceptionally, rather costly compared to other market competitors. You could easily justify its high price tag given its promised advantages over the aSi-TFT IPS. Thus, it would feel like an investment on your behalf.

Some might question whether it’s worth it, especially if you have to buy it immediately. Again, since the IGZO is new, there are many opportunities for its price to decrease as it gains more traction in the marketplace.

Only a few brands manufacture IGZO nowadays, and the majority of those brands are well-known and not exactly recognized for being inexpensive. Nobody is preventing you from purchasing an IGZO, though, if that’s a risk you’re prepared to take.

Is The IGZO Something You Need?

The second factor stands if you have the money to purchase your highly desired IGZO screen, but would it be a wise investment? Consider the purpose of your purchase and whether it will materially improve your gaming experience before making a decision. Generally speaking, if you are considering performance, the IGZO’s short response time and high refresh rates are fairly persuasive.

Is It Available?

The IGZO is not widely available in TV and monitor brands because it is still quite new. To purchase it, you would need to either visit the top retailers or place an online order. Hunting for an available stock will be a problem because it is not easily accessible.

There may be a few annoyances when searching for available stock, but other than that, there is nothing wrong with this brand-new prototype.

What is IGZO material?

IGZO is a cutting-edge semiconductor material that has revolutionized display technology. Known for its exceptional electron mobility, IGZO offers several advantages over traditional materials like amorphous silicon. This translates to faster pixel switching speeds, which result in more responsive and energy-efficient displays.


Greater transparency, faster response times, higher refresh rates, increased pixel density, and improved color accuracy are all benefits of using an IGZO backplane. Additionally, IGZO TFTs are 20 to 50 times more efficient while using 80 to 90% less power than amorphous silicon TFTs.

Due to the high cost of Indium and Gallium (rare earth minerals) and the limited adoption of the methods used to deposit IGZO on backplanes, IGZO deployment is expensive. These expenses are then passed on to you and me, the customers.

IGZO is a backplane technology that may be used with various LCD panels, including VA, TN, and IPS. The existing fantastic display technologies would be substantially enhanced by this technique, which applies to OLED devices.

While a-Si, LTPS, or IGZO TFT transistors control the pixels on a screen. IPS is a type of panel that can be coupled with these transistors efficiently. Hope you are able to differentiate between the two now.
