What is Local Dimming?
Local Dimming technology is a feature commonly found in high-end TVs that significantly improves the picture quality by allowing for more precise control over the backlighting of the screen. Instead of having a uniform backlight across the entire screen, Local Dimming enables specific areas to dim or brighten independently, resulting in enhanced contrast and superior image quality.
By selectively dimming or brightening different areas of the screen, Local Dimming achieves deeper blacks and brighter whites, creating a more realistic and immersive viewing experience. This technology is particularly useful when watching movies or TV shows with scenes that have a combination of bright and dark elements.
How does Local Dimming work?
Local Dimming works by dividing the TV screen into multiple zones, with each zone being independently controlled. These zones can vary in number, depending on the TV model and brand, but the more zones a TV has, the better the Local Dimming performance will be.
Each zone can be dimmed or brightened individually, depending on the content being displayed. When a scene requires deep blacks, the zones corresponding to dark areas on the screen will be dimmed, effectively reducing the backlight intensity. Conversely, when a scene requires bright whites, the zones associated with those areas will be brightened, creating a more vibrant and detailed image.
Local Dimming algorithms analyze the content being displayed in real-time to determine which zones should be dimmed or brightened. This dynamic adjustment ensures that the backlighting is precisely controlled to deliver optimal contrast and picture quality.

Limitations of Local Dimming
Local Dimming is a popular technology used in modern televisions to enhance contrast and improve black levels. It dynamically adjusts the backlight behind specific areas of the screen, resulting in deeper blacks and brighter whites. While Local Dimming offers significant benefits, it is important to be aware of its limitations. In this section, we will delve into the potential drawbacks and discuss how they can impact your viewing experience.
Blooming or Halo Effects
One limitation of Local Dimming is the possibility of blooming or halo effects. This occurs when the dimming zones, which control different sections of the screen, are not well-implemented. In certain scenarios, light leakage from bright areas adjacent to dark areas can cause unwanted brightness bleeding, resulting in halos around bright objects or a blooming effect around on-screen text or logos.
To mitigate this issue, manufacturers have employed various techniques. Some models feature more dimming zones to provide finer control over the backlight, reducing the occurrence of blooming or halo effects. Additionally, advanced algorithms and local dimming algorithms have been developed to enhance the accuracy of the dimming process, minimizing the chances of blooming.
Impact of Room Brightness
Another factor that can affect the effectiveness of Local Dimming is the brightness of the room where the television is located. In brightly lit rooms, the contrast enhancement provided by Local Dimming may be less noticeable. This is because the ambient light can wash out the effect of dimming specific areas, making it difficult to achieve vibrant blacks and bright whites.
In such cases, it is recommended to adjust the backlight settings of the television accordingly. Increasing the brightness of the backlight can help compensate for the ambient light and maintain a satisfying contrast level. However, keep in mind that excessive brightness may lead to reduced black levels, so finding the right balance is crucial.
Viewing Angles and Local Dimming
Local Dimming can also be influenced by the viewing angles of the screen. While most televisions offer excellent picture quality when viewed head-on, the performance may degrade when viewed from the sides. This is because the dimming zones are designed to optimize the picture quality for the main viewing position, often resulting in diminished contrast and blooming effects when viewed from extreme angles.
To mitigate this limitation, it is advisable to choose a television with wider viewing angles and superior local dimming algorithms. OLED (Organic Light Emitting Diode) televisions, for example, are renowned for their excellent viewing angles and superior black levels, as each pixel is capable of independent dimming.
When choosing a television for your movie-watching experience, it’s important to consider various factors that can affect the quality of your viewing.
