The IPS (In-Plane Switching) technology has revolutionized the world of displays, offering vibrant colors, wide viewing angles, and fast response times. However, like any other technology, IPS panels are not without their drawbacks. One of the most common issues associated with IPS displays is the phenomenon known as IPS glow. In this article, we will delve into the world of IPS glow, exploring its causes, effects, and potential solutions to help you make the most out of your display.
Introduction to IPS Glow
IPS glow refers to the faint, often yellowish or white, glow that appears around the edges or corners of an IPS display, particularly when the screen is displaying a dark or black image. This glow can be distracting and may affect the overall viewing experience, especially in low-light environments. While IPS glow is not unique to IPS panels and can be observed in other display technologies as well, it is more pronounced in IPS displays due to their inherent characteristics.
Causes of IPS Glow
So, what causes IPS glow? The primary reason behind this phenomenon is the way IPS panels are constructed. IPS panels use a layer of liquid crystals to block or allow light to pass through a matrix of pixels. When an electric current is applied, the liquid crystals align to either block or allow light to pass through, creating the images we see on the screen. However, the liquid crystals do not completely block the light, resulting in a small amount of light leakage around the edges of the panel. This light leakage is what we perceive as IPS glow.
Another factor contributing to IPS glow is the backlighting system used in IPS displays. Most IPS panels use a backlight, typically an array of LEDs, to illuminate the liquid crystals. The backlight can sometimes bleed around the edges of the panel, exacerbating the glow effect. The type and quality of the backlight, as well as the panel’s backlight diffusion system, can significantly impact the severity of IPS glow.
Panel Quality and Manufacturing Variations
The quality of the IPS panel itself also plays a crucial role in determining the severity of IPS glow. Panels from different manufacturers or even different production batches can exhibit varying levels of glow due to differences in materials, construction, and quality control. Higher-quality panels with better backlight diffusion systems and more efficient liquid crystal alignment tend to exhibit less glow.
Effects of IPS Glow on Display Performance
IPS glow can have a noticeable impact on the overall display performance, particularly in certain scenarios. For example, when watching movies or playing games with dark scenes, the glow can be distracting and may reduce the perceived contrast ratio of the display. In graphic design, video editing, or other applications where color accuracy is critical, IPS glow can affect the color representation and make it challenging to achieve precise color matching.
Furthermore, IPS glow can also be a concern for gamers, as it can affect the immersion and overall gaming experience. In fast-paced games, the glow can be particularly noticeable, especially when playing in low-light environments. However, it’s worth noting that the impact of IPS glow on gaming performance is generally less significant than other factors such as response time, input lag, and refresh rate.
Solutions to Minimize IPS Glow
While IPS glow is an inherent characteristic of IPS panels, there are several steps you can take to minimize its impact:
To reduce IPS glow, you can try adjusting the display’s settings, such as reducing the brightness or adjusting the color temperature. Using a calibration tool or software can also help optimize the display’s performance and minimize glow. Additionally, using a display with a high-quality backlight diffusion system or a panel with a more efficient liquid crystal alignment can help reduce glow.
In terms of display selection, look for panels with features such as local dimming, which can help reduce backlight bleed and minimize glow. Some displays also come with glow reduction technologies, such as ASUS’s Dynamic Backlight or Acer’s Adaptive Backlight, which can help mitigate the glow effect.
Future Developments and Alternatives
As display technology continues to evolve, we can expect to see improvements in IPS panel design and manufacturing that will help reduce IPS glow. New technologies such as Quantum Dot and OLED (Organic Light-Emitting Diode) are already showing promise in minimizing glow and improving overall display performance. OLED panels, in particular, are known for their exceptional contrast ratios and true blacks, which make them less susceptible to glow.
While OLED panels are still more expensive than IPS panels, they offer several advantages, including faster response times, wider viewing angles, and more vivid colors. As the cost of OLED technology continues to decrease, we can expect to see more affordable OLED displays that offer superior performance and minimal glow.

What is IPS glow and how does it affect display performance?
IPS glow refers to the phenomenon where a faint glow or light leakage appears around the edges or corners of an In-Plane Switching (IPS) display, particularly when viewed in a dark environment. This issue is more noticeable when the display is showing a dark or black image, as the glow can be distracting and detract from the overall viewing experience. IPS glow is caused by the way the IPS panel is constructed, with the liquid crystals and polarizers allowing some light to pass through and escape from the edges of the panel.
The effects of IPS glow can be significant, especially for users who value accurate color representation and deep blacks. In addition to being distracting, IPS glow can also reduce the perceived contrast ratio of the display, making it less effective at displaying subtle details in dark scenes. Furthermore, IPS glow can be more pronounced in certain viewing angles, which can limit the display’s overall usability. However, it’s worth noting that not all IPS displays exhibit significant IPS glow, and some manufacturers have developed technologies to minimize or eliminate this issue. By understanding the causes and effects of IPS glow, users can make informed decisions when selecting a display and take steps to mitigate its impact on their viewing experience.
What are the main causes of IPS glow, and how do they relate to display construction?
The main causes of IPS glow are related to the construction of the IPS panel, including the type and quality of the liquid crystals, polarizers, and backlighting used. The liquid crystals in an IPS panel are designed to block or allow light to pass through, depending on the voltage applied to them. However, some light can still leak through the edges of the panel, particularly if the liquid crystals are not perfectly aligned or if the polarizers are not effective at blocking light. Additionally, the backlighting used in IPS displays can also contribute to IPS glow, as it can cause light to scatter and escape from the edges of the panel.
The relationship between display construction and IPS glow is complex, and manufacturers must carefully balance the trade-offs between different design factors to minimize the occurrence of IPS glow. For example, using higher-quality liquid crystals and polarizers can help reduce IPS glow, but may also increase the cost and power consumption of the display. Similarly, optimizing the backlighting system can help reduce light leakage, but may also affect the display’s brightness and color accuracy. By understanding the causes of IPS glow and how they relate to display construction, manufacturers can develop more effective solutions to mitigate this issue and improve the overall performance of their displays.
How does IPS glow affect the color accuracy and contrast ratio of a display?
IPS glow can have a significant impact on the color accuracy and contrast ratio of a display, particularly in dark environments.

Additionally, some displays may use features such as backlight adjustment or dynamic contrast ratio to help minimize IPS glow. These solutions can be effective at reducing the appearance of IPS glow, but may also increase the cost and complexity of the display.
In addition to these technological solutions, users can also take steps to minimize the appearance of IPS glow. For example, adjusting the display’s brightness and color temperature can help reduce the visibility of IPS glow, particularly in bright environments. Additionally, using a display with a higher contrast ratio and better black levels can help minimize the impact of IPS glow on the overall viewing experience. By combining these solutions with an understanding of the causes and effects of IPS glow, users can optimize their display’s performance and enjoy a more immersive and engaging viewing experience.
How do different display technologies, such as VA and TN, compare to IPS in terms of IPS glow?
Different display technologies, such as Vertical Alignment (VA) and Twisted Nematic (TN), have distinct characteristics that affect their susceptibility to IPS glow. VA panels, for example, are known for their high contrast ratios and deep blacks, which can make them less prone to IPS glow. TN panels, on the other hand, are often more prone to light leakage and may exhibit more noticeable IPS glow, particularly in dark environments. In contrast, IPS panels are designed to offer a balance between color accuracy, contrast ratio, and viewing angles, but may be more susceptible to IPS glow due to their construction.
The comparison between different display technologies is complex, and the choice of technology depends on the specific needs and preferences of the user. For example, users who prioritize color accuracy and wide viewing angles may prefer IPS panels, despite their potential for IPS glow. On the other hand, users who value high contrast ratios and deep blacks may prefer VA panels, which can offer better performance in these areas. By understanding the strengths and weaknesses of different display technologies, users can make informed decisions and choose the best display for their needs, taking into account factors such as IPS glow and other performance characteristics.
Can IPS glow be completely eliminated, or is it an inherent limitation of IPS technology?
While IPS glow can be minimized through various technological solutions and display calibration, it is unlikely to be completely eliminated as an inherent limitation of IPS technology. The construction of IPS panels, including the use of liquid crystals and polarizers, will always allow some light to leak through the edges of the panel. However, manufacturers can continue to develop and refine technologies to reduce the appearance of IPS glow, such as advanced backlighting systems and improved liquid crystals. Additionally, users can take steps to minimize the visibility of IPS glow, such as adjusting the display’s brightness and color temperature.
The ongoing development of display technologies is focused on addressing the limitations of IPS panels, including IPS glow. For example, new technologies such as OLED (Organic Light-Emitting Diode) and micro-LED offer the potential for true blacks and infinite contrast ratios, which can eliminate the issue of IPS glow. However, these technologies are still evolving and may have their own limitations and trade-offs. By understanding the inherent limitations of IPS technology and the potential of emerging display technologies, users can stay informed about the latest developments and make informed decisions about their display needs, taking into account factors such as IPS glow and other performance characteristics.
How can users diagnose and assess the severity of IPS glow on their display?
Users can diagnose and assess the severity of IPS glow on their display by performing a simple test, such as displaying a black image or a dark scene in a movie.
