Backlight bleed is a common issue in LED TVs and monitors, where light leaks from the edges or corners of the screen, creating visible bright spots, especially on dark backgrounds. This happens when the backlight, usually positioned behind the display panel, does not fully align with the screen's layers. Causes can include manufacturing defects, improper assembly, or physical damage to the display. While some level of backlight bleed is normal in certain displays, excessive bleeding can impact the viewing experience. Regular calibration, proper handling, and investing in higher-quality displays can help minimise this problem. For the latest

How backlight bleed affects TV viewing
- Decreases picture quality: Backlight bleed creates visible bright spots on the screen, which can reduce the clarity and contrast of dark scenes, negatively impacting picture quality.
- Disrupts immersion: In dark or black scenes, light leakage can be distracting, breaking the immersive experience, especially during movies, gaming, or viewing content with darker tones.
- Reduces colour accuracy: The uneven brightness caused by backlight bleed can affect colour accuracy, making certain colours appear distorted or inconsistent.
- Affects viewing angles: The severity of backlight bleed can become more noticeable in the LG Smart TV 32 inch when viewing from an angle, making it harder to enjoy content comfortably from different positions.
- Frustrating for high-end displays: Backlight bleed is particularly noticeable in higher-end 55 inch TVs, where you expect perfect contrast and crisp details, making it an undesirable issue in premium models.
Methods for fixing backlight bleed
- Adjust picture settings: Lower the brightness and tweak the contrast settings on your TV. Reducing these can help minimise the visibility of backlight bleed, especially in dark scenes.
- Enable local dimming: Many modern LED TVs come with a local dimming feature that adjusts the brightness in specific areas of the screen. This helps to reduce backlight bleed and enhances black levels.
- Use a full-screen dark image: Viewing dark content or a black screen can make the backlight bleed less noticeable. This method reduces the impact by allowing you to spot the bleed easily and adjust settings accordingly.
- Reposition the TV: If the LED TV is not mounted correctly or is too close to the wall, it can cause improper airflow or uneven lighting. Ensuring proper ventilation and correct positioning may help reduce backlight bleed.
- Professional repair or replacement: If the bleed persists or is severe, consider seeking professional repair services or replacing the panel. Some warranties might cover this issue if it is identified as a defect.
Checking for backlight bleed on new TVs
- Display a dark image: To check for backlight bleed, display a completely black screen or dark content. This will highlight any light leakage around the edges or corners.
- Look for uneven brightness: Examine the screen for areas where the brightness is noticeably higher, especially along the edges or corners. These are the most common spots for backlight bleed.
- Adjust viewing angles: Sit in different positions and check how the backlight bleed appears from various angles. In some cases, it may be more visible from certain perspectives.
- Test with different content: Play content with dark scenes to see if backlight bleed is more noticeable during movies or gaming, as bright content might mask the issue.
- Use a flashlight for detection: Shine a flashlight at a steep angle along the edges of the Sony TV screen to spot any uneven lighting, helping you detect backlight bleed more easily.
Preventing backlight bleed in future models
To prevent backlight bleed in future models, manufacturers focus on improving panel construction and enhancing the quality control processes during production. One of the primary factors is better alignment of the backlight and the LCD layers. By using more precise manufacturing techniques and higher-quality materials, the risk of light leakage can be minimised. Additionally, employing higher-end LED technologies, such as OLED, can effectively eliminate the risk of backlight bleed, as these displays do not rely on backlights.
For consumers, ensuring you choose a high-quality TV brand with a good warranty and strong customer support can help mitigate backlight bleed issues. Moreover, opting for models with local dimming and advanced calibration options can help reduce its visibility. By choosing the right model and properly setting up your TV, you can minimise or even eliminate the effects of backlight bleed in your future purchases.
