IGZO Vs IPS – What’s The Difference?

We hear about new inventions daily, particularly in the IT industry. Some of them spark our interest, while others fail to do so. Furthermore, the display screen and high-resolution technologies have constantly been developing in the past decade.

The screen panel kinds have been mentioned many times in the product’s technical specifications. But are you familiar with the term “screen panel”?

However, the kind of backplane technology utilized in the display is a critical aspect that is often neglected during research and debate. It is something to keep in mind. Displays and resolutions are unquestionably becoming more robust. As a result, it’s becoming more challenging to see the difference between them.

Let’s concentrate on the display screen’s IPS and IGZO technologies. When it comes to comparisons, they’ve always been the topic of remarks about receiving a great deal of attention from both sides.  One person prefers IGZO, while the other believes an IPS screen is superior.

So, let’s take a look at each display technology and see what they can do for us. With this article, readers can learn about the distinctions between IGZO and IPS screen technology.

What Is An IGZO Display?

An IGZO display is not the same as a display panel in any way. On the other hand, IGZO displays are those displays that utilize a thin-film transistor (TFT) constructed of indium gallium zinc oxide as the backplane.

It means that IGZO display technology is compatible with a variety of display panels, including TN LCDs (twisted nematic), IPS LCDs (in-plane switching), and OLEDs (organic light-emitting diodes).

What is IPS?

A kind of monitor display and screen technology is known as In-Plane Switching, or IPS, is a method of switching pixels on and off. An IPS display is a kind of TFT LCD (or “active matrix” LCD).

IPS panels have the best color and viewing angles compared to TN (twisted nematic) and VA (vertical alignment) displays.

The high contrast of the IPS is one of its most appreciated features. It is also well-known for the high degree of color accuracy and uniformity it exhibits. It is the perfect panel for anybody who enjoys working with graphics.


Samsung and Sharp have both obtained licenses for the IGZO (Indium Gallium Zinc Oxide) compound semiconductor. On the other hand, Sharp was the first to use IGZO technology in smartphones, tablets, and 32-inch LCDs.

It is expensive because rare metals like indium and gallium are used to make the IGZO transistor. With a 4K resolution and a 14-bit Look-Up Table for accurate calibration, the NEC PA322UHD supports 99.2% of the Adobe RGB color gamut.

It costs about $3000 and comes with an IGZO-TFT IPS panel. The AOC 24G2, an inexpensive and popular 1080p 144Hz IPS gaming monitor, is one of the most affordable IGZO displays.

TFT IPS Display With IGZO Vs. A-Si

The primary benefit of IGZO at present is its very low power consumption. Because of the greater electron mobility, which is 20-50 times quicker than that of a standard panel, it is up to 80%-90% more power-efficient than a standard a-Si panel display.

Faster reaction time, more excellent color rendition, and increased pixel density are other advantages. Unlike a-Si panel monitors, which use more electricity to backlight greater pixel density displays, IGZO monitors use much less power and provide even brighter pictures.

Portable devices with high pixel densities will benefit greatly from this technique. IGZO offers superior resolution, speed, and pixel density regardless of the screen size.

A 6-inch IPS display with a 2560×1600 resolution and 498 pixels per inch was used in one of the prototypes.

A Few Benefits Of Using IGZO Tfts On IPS Panels

  • Innovative And Powerful Technology:

High electron mobility, charge retention (owing to minimal current leakage), and transparency of IGZO when used on IPS and OLED screens will make it a powerful technology.

If your TV or monitor uses less power, you’ll save money on batteries by using an IGZO TFT display.

  • Faster Response Times:

In addition, faster response times may be a significant advantage for gamers. You don’t have to compromise on color accuracy to have better response times. On IPS panels, an IGZO backplane may reduce response time from several milliseconds to less than five milliseconds (up to 1ms).

Even better than an a-SI TN panel in terms of performance. An IGZO backplane may also boost refresh rates, providing players an advantage while playing competitive and high-fps games.

  • Higher Pixel Density:

A greater pixel density is the third significant benefit. The amount of pixels on a one-inch squared display is measured in pixel density or PPI. Transparency and excellent efficiency of IGZO TFTs allow for higher pixel densities.

For additional pixels, transistors may be filed and shrunk even further without compromising performance. A higher PPI provides more clarity and detail for a more satisfying viewing experience.

  • Reduce Noise

Additionally, IGZO semiconductors enhance touch sensitivity by reducing noise on sensitive devices like touchscreens. As a result, writing or sketching on an OLED iPad mini or pro with an IGZO backplane seems more realistic and satisfying.

Problems With IGZO Integration

In terms of IGZO TFTs, the primary issue is the high price of display integration. To put it another way, IGZO deposition on backplanes is prohibitively costly because of the high cost of Indium and Gallium (rare earth materials).

These expenses are subsequently passed on to the general public. As a result, the technology is only widely used on devices with tiny screens, such as smartphones, iPads, etc. Furthermore, this material has yet to be extensively used on bigger screens.

TVs and monitors with large screens, such as IGZO backplanes, are now costly. Still, we may anticipate the price to decrease as more businesses license the technology. TFTs improve and become more affordable as the underlying technology and implementation techniques improve.


IGZO has features that have never been seen before and are unique for those who want to stand out. On top of that, IPS stands out for being readily accessible, affordable, and producing a high-quality result.

The only real difference is that IGO provides you with a more comprehensive and visually beautiful experience thanks to high-tech functionality. Overall, IGZO takes a more forward-looking approach while using less power. And it’s easily accessible to IPS, which provides the service with a great deal of privilege.
