IPS glow is a phenomenon seen in IPS panel displays where light appears along the edges of the screen, especially in dark scenes. While not a defect, it can affect the viewing experience. To reduce IPS glow, adjusting the screen's brightness and contrast can help. Additionally, lowering the ambient light in the room or adjusting the viewing angle can minimise its effect. Opting for models with better quality IPS panels may also reduce IPS glow.

Introduction

IPS glow is a common issue in IPS (In-Plane Switching) panel displays, particularly noticeable in dark scenes. This phenomenon occurs when light leaks from the edges of the screen, creating a glowing effect, especially when viewed at an angle. While IPS displays offer superior color accuracy and wider viewing angles compared to traditional TN (Twisted Nematic) panels, IPS glow can still be distracting to some users. This effect is more pronounced on larger screens and at higher brightness levels. Understanding IPS glow and its causes can help you reduce its impact, improving your overall screen experience.

Ways to reduce IPS glow on your TV

  • Lower the brightness: Reducing the brightness level helps minimise the appearance of IPS glow, especially in dark scenes.
  • Adjust the contrast: Balance the light and dark areas on the screen to reduce the glow.
  • Optimal viewing angle: Sit directly in front of the screen, as the IPS glow is more noticeable at extreme angles.
  • Use a better quality IPS panel: 55 inch TVs with advanced backlight technology and higher-quality IPS panels typically reduce IPS glow.
  • Enable local dimming: If available, use the local dimming feature to improve black levels and lessen IPS glow in dark scenes.

Choosing the right room lighting for the best viewing

  • Use soft, ambient lighting: Gentle lighting in the LED TVs helps avoid reflections and glare on the screen.
  • Position lights away from the TV: Place lamps at an angle to prevent direct light from hitting the screen.
  • Avoid bright overhead lights: These can worsen the visibility of IPS glow.
  • Opt for indirect or floor lamps: These create softer, more diffused light in the room.
  • Dim lighting: Dim lighting helps improve contrast and reduce eye strain, ensuring better picture quality.

Calibration tools for reducing IPS glow

  • Use professional calibration tools: Tools like colourimeters and software (for example, CalMAN or DisplayCAL) help optimise the TV’s picture settings, reducing IPS glow by improving overall image quality.
  • Adjust gamma settings: Calibrate the gamma to balance the brightness across the screen, which helps reduce the visibility of the IPS glow.
  • Fine-tune contrast and backlight: By calibrating the contrast and backlight settings, you can control light distribution, which can reduce the IPS glow effect.
  • Enable advanced picture modes: Many modern TVs offer professional picture modes that automatically adjust the brightness and colour balance, which can help minimise IPS glow.
  • Adjust viewing angle: Calibration software can help you adjust your TV’s settings to optimise performance based on your viewing distance and angle.

Monitor vs TV IPS glow effects

When comparing monitors and TVs, the IPS glow effect can differ significantly due to their intended use and display technologies. On monitors, IPS glow is often more noticeable, especially when working with dark content, because the viewing distance is much closer, and users are more sensitive to screen imperfections. Monitors are typically designed for high-precision tasks, so the glow might be more bothersome in a professional setting.

On the other hand, TVs are usually viewed from a greater distance, which can make IPS glow less noticeable. However, larger TV screens, especially in dark viewing environments, may still exhibit a visible glow at certain angles. TVs with better backlighting, local dimming features, and advanced IPS panels may minimise these effects significantly.

In terms of usage, IPS glow is often a more critical issue for those using monitors for gaming or graphic design, where colour accuracy and visual clarity are paramount. TVs, while still susceptible to IPS glow, offer more flexibility with features like ambient lighting, picture modes, and viewing angles that can reduce its impact.

For a better viewing experience, explore Sony LED TVs, which offer superior picture quality and IPS glow reduction technology.

Frequently asked questions

How do I reduce the IPS glow on my TV?
To reduce the IPS glow on your TV, you can start by adjusting the brightness and contrast settings to lower levels, as this can decrease the intensity of the glow. Using professional calibration tools like colourimeters or software, such as CalMAN or DisplayCAL, can help fine-tune your TV's picture settings, further reducing the IPS glow. Additionally, adjusting your viewing angle and reducing the room's ambient light can minimise the effect. Switching to advanced picture modes like Movie or Expert settings can also help optimise the display and reduce IPS glow visibility.

What causes IPS glow?
IPS glow is caused by the design of IPS (In-Plane Switching) panels, where the backlight shines through the liquid crystal cells of the panel. This can lead to light leakage, which is visible as a faint glow, particularly around the edges or corners of the screen when viewed from certain angles. The glow is most prominent in dark scenes or low-light environments, and it happens because the panel's light diffusion properties are not perfect. Although it is an inherent characteristic of IPS technology, it can be minimised with adjustments.

Can IPS glow affect all TVs?
IPS glow mainly affects TVs with IPS (In-Plane Switching) panels, commonly found in LED or LCD TVs. While OLED screens, which use organic light-emitting diodes, are less prone to IPS glow, they can have other issues, such as burn-in. IPS panels, on the other hand, offer better colour accuracy and wider viewing angles but are more susceptible to light leakage, which leads to the IPS glow. Therefore, if your TV uses an IPS panel, you are more likely to experience this issue compared to other display technologies.

Is the IPS glow noticeable in dark scenes?
Yes, IPS glow is most noticeable in dark scenes, especially those with large black or dark-coloured areas. When viewing dark content, the contrast between the light coming from the backlight and the dark pixels becomes more apparent, making the glow visible. This effect is particularly noticeable in the corners or edges of the screen and may reduce the overall quality of the viewing experience. However, in bright scenes or content with more colours, the IPS glow is typically less noticeable, as the bright light from the screen overshadows the glow.

Does IPS glow affect gaming or movies?
Yes, IPS glow can be noticeable during gaming or movie watching, particularly in dark or black scenes. For gamers, this can disrupt the immersive experience, especially in dark-themed games or cinematic cut scenes. Movies with high contrast or scenes in dark environments might also reveal the IPS glow, affecting the viewing experience. However, in brightly lit scenes or during fast-paced action, the glow may not be as noticeable. While not a deal-breaker, it can be distracting for those who prioritise visual accuracy and immersion in dark scenes.
