The world of display technology has witnessed significant advancements in recent years, with two prominent contenders vying for dominance: IPS (In-Plane Switching) and LED (Light Emitting Diode). Both technologies have their own set of advantages and disadvantages, making it challenging for consumers to decide which one is better suited for their needs. In this in-depth article, we’ll delve into the details of IPS and LED displays, exploring their differences, similarities, and applications to help you make an informed decision.
Understanding IPS Displays
IPS is a type of LCD (Liquid Crystal Display) technology that uses a specific alignment of liquid crystals to produce images. Developed by LG Display in 2001, IPS aims to address the limitations of traditional TN (Twisted Nematic) LCDs, which often suffer from poor viewing angles and limited color reproduction.
How IPS Displays Work
IPS displays consist of a layer of liquid crystals sandwiched between two glass substrates. When an electric current is applied, the liquid crystals align in a specific plane, allowing light to pass through and creating images. The unique alignment of liquid crystals in IPS displays enables better light transmission, resulting in improved color accuracy, higher contrast ratios, and wider viewing angles.
Advantages of IPS Displays
IPS displays have several benefits that make them a popular choice among gamers, graphic designers, and movie enthusiasts:
- Wider Viewing Angles: IPS displays maintain their color accuracy and contrast even when viewed from the side, making them ideal for collaborative work or watching movies with friends.

What is the main difference between IPS and LED displays?
IPS (In-Plane Switching) and LED (Light Emitting Diode) are two different display technologies used in monitors and televisions. The main difference between the two lies in their panel types and backlighting systems. IPS panels are known for their excellent color accuracy, wide viewing angles, and good brightness levels. On the other hand, LED displays use an LED backlight, which can be either edge-lit or full-array, to illuminate the LCD panel.
IPS panels are generally considered better suited for professional and gaming applications, where color accuracy and consistency are crucial. LED displays, with their ability to produce higher contrast ratios and faster response times, are often preferred for entertainment purposes such as watching movies and playing games. However, it’s essential to note that LED is a backlight technology and can be used with various panel types, including IPS, VA, and TN.
Which display type is better for gaming?
For gaming, the choice between IPS and LED displays largely depends on personal preferences and the type of games you play. If you’re a competitive gamer who values fast response times and low input lag, an LED display with a TN (Twisted Nematic) panel might be the better option. TN panels are known for their rapid response times, making them well-suited for fast-paced games. However, they often compromise on color accuracy and viewing angles.
On the other hand, if you’re a gamer who prefers immersive, visually stunning experiences with accurate colors and wide viewing angles, an IPS display might be the way to go. While IPS panels may not be as fast as TN panels, they offer better color reproduction and a more cinematic experience. Additionally, many modern IPS gaming monitors feature fast response times and high refresh rates, making them well-suited for gaming.
Do IPS displays consume more power than LED displays?
IPS displays generally consume more power than LED displays, especially when it comes to edge-lit LED displays. This is because IPS panels require a more complex backlight system to achieve their characteristic wide viewing angles and good color accuracy. As a result, IPS displays tend to draw more power to operate the backlight and maintain a consistent brightness level.
However, it’s essential to note that power consumption can vary greatly depending on the specific display model, panel type, and features such as local dimming and HDR support. Some modern IPS displays with power-saving features and local dimming can be quite energy-efficient, while some LED displays with full-array backlights and HDR capabilities can consume a significant amount of power.
Can IPS displays suffer from backlight bleeding?
IPS displays, by their very nature, are less prone to backlight bleeding due to their panel structure and backlight design. Backlight bleeding occurs when the backlight leaks through the LCD panel, causing uneven brightness and discoloration along the edges. IPS panels, with their in-plane switching technology, are designed to minimize backlight bleeding and provide a more uniform brightness distribution.
That being said, it’s not impossible for an IPS display to suffer from backlight bleeding. Poor panel quality, manufacturing defects, or wear and tear over time can still cause backlight bleeding issues in IPS displays. However, these issues are relatively rare and often less severe than those found in LED displays, especially edge-lit models.
Are LED displays more prone to image retention?
LED displays, especially those with VA (Vertical Alignment) panels, can be more prone to image retention than IPS displays. Image retention, also known as burn-in, occurs when a static image is displayed on the screen for an extended period, causing a faint imprint to remain even after the image has changed. VA panels, with their ability to produce high contrast ratios, are more susceptible to image retention due to their pixel structure and voltage requirements.
IPS displays, on the other hand, are less likely to suffer from image retention due to their pixel structure and the way they switch pixels on and off. This makes IPS displays a better choice for applications where static images are frequently displayed, such as video game menus, TV channel logos, or computer icons.
Can IPS displays produce true blacks?
IPS displays, by their very nature, are unable to produce true blacks due to their backlight-based design. Since IPS panels rely on a backlight to illuminate the LCD panel, they can only achieve a certain level of darkness by dimming the backlight or using local dimming. While IPS displays can produce very dark blacks, they can never achieve the same level of true blacks as OLED (Organic Light-Emitting Diode) displays, which can turn off individual pixels to produce absolute blackness.
That being said, many modern IPS displays feature advanced local dimming technologies that can simulate true blacks by dynamically adjusting the backlight and LCD panel to create a more immersive viewing experience. While these technologies can’t replicate the true blacks of OLED displays, they can still provide excellent contrast ratios and impressive picture quality.
Are IPS displays more expensive than LED displays?
Historically, IPS displays were more expensive than LED displays, especially in the early days of IPS technology. However, with advancements in manufacturing and economies of scale, the price gap between IPS and LED displays has narrowed significantly. Today, you can find IPS displays in various price ranges, from budget-friendly options to high-end models with advanced features.
In general, IPS displays with advanced features such as high refresh rates, G-Sync or FreeSync, and HDR support tend to be more expensive than their LED counterparts. However, if you’re looking for a budget-friendly option with good color accuracy and wide viewing angles, an IPS display might be a more affordable choice than a high-end LED display with similar features.
