How to Select an Appropriate Brightness Level For LED Screens

LED display screens have quickly become ubiquitous across society today, from subway stations and shopping malls to office buildings and conference rooms. Their energy-efficiency and brightness has earned them widespread popularity; yet many hold onto an outdated misconception: that brighter is better. In this blog we explore How Can You Select an Appropriate Brightness Level For LED Screens.

What Is an LED Screen Brightness?

LED technology relies on light-emitting diodes which boast both low energy consumption and bright illumination, so its manufacturers often highlight these qualities to attract customers. Unfortunately, excessive brightness runs counter to energy efficiency goals; so what exactly could connect high brightness and energy efficiency goals?

Brightness Range for LED Display Screens

The appropriate brightness levels of an LED screen depend heavily upon its intended use case, however we typically advise using two levels as general guidelines:

Indoor:Less than 1,000 nits

Semi-outdoor:3,000-5,000 nits

Outdoors:5,000-10,000 nits

However, the brightness of an LED screen may vary based on the specific usage and installation location in practical projects. For indoor applications, different usage scenarios are as follows:

Indoor Usage:

Document presentation: 200-300 nits

Video playback: 400-600 nits

Advertising: 600-1,000 nits

Regarding different installation locations, let’s take outdoor LED walls as an example. If the LED display is facing east or west, directly exposed to sunlight, a minimum brightness of at least 7,000 nits is required to combat the sun’s glare. However, if the LED display is facing south or north, the minimum brightness can be lowered to 6,000 nits.

Deliberately making displays too bright can cause issues and in some areas there may even be regulations restricting their brightness.

When it comes to brightness adjustments, it’s essential that users understand that pushing it beyond its recommended limit might not always be best practice. Similar to how car tires have specified pressure limits for safe usage and performance purposes, exceeding recommended brightness range for LED display screens could create issues and compromise their lifespan and performance over time.

Negative Effects of Excessive LED Screen Brightness

Furthermore, setting too-high LED display screen brightness levels may result in several detrimental consequences:

Lifespan of an LED Display Screen:

An LED display screen’s lifespan depends directly upon its LEDs; higher levels of brightness cause increased current to pass through individual diodes, leading to faster degradation rates and decreasing lifespan over time.

Power Consumption for Outdoor LED Screens:

 Increased brightness usually leads to greater power usage and can significantly impact electricity costs and make this technology less energy-efficient.

Eye Strain and Potential Harm:

Overly-bright LED displays at night may lead to discomfort and even permanent eye strain for viewers, similar to how flashlight beams temporarily blurred vision in dark rooms. Bright displays can blindingly shine light onto viewers’ retinas causing temporary blind spots or accidents which might result from this direct light exposure.

Project costs tend to skyrocket as users pursue extreme brightness for their project requirements, often at great expense and resource waste. When selecting LED displays, it is critical not to fall for the common misconception that more brightness equals better LED screens; blindly chasing brightness may result in compromised image quality, reduced lifespans and extra expenses that arise out of its pursuit.

Balance Brightness and Environment

LED displays in urban environments must keep a balance between brightness and environmental consideration when choosing LED displays, particularly those designed for LED television screens. Focusing too heavily on brightness alone could have adverse environmental ramifications; thus making an irrational approach counter-productive.

Brightness Settings and Protection for LED Display Screens

In order to ensure safe use of LED display screens, various measures can be taken:

Adjust Brightness Based on Environment:

To provide an enjoyable viewing experience without eye strain or glare, LED display screen brightness should be customized according to ambient lighting conditions and viewing environments.

Regulate Blue Light Output:

Users should take measures to limit blue light output of outdoor LED displays for viewer safety as excessive blue light exposure may be harmful.

Monitor Light Distribution and Direction:

Make sure the light from LED displays is evenly spread within their viewing angles to avoid direct, intense light exposure to eyes.

Determine Appropriate Output Frequencies:

LED display screen manufacturers must abide by standard requirements regarding screen output frequencies in order to prevent flickering and viewer discomfort.

Incorporate Safety Instructions:

LED display screen manufacturers should include safety guidelines in their user manuals that advise how users should adjust brightness correctly while also alerting them about possible eye damage from prolonged screen usage.

Implement Protective Measures in Production:

As part of the design and manufacturing processes for LED display screens, proper precautions must be taken during production to protect employees from direct light sources – this may involve wearing appropriate eyewear during their exposure time.

LED Screen Manufacturers Use Different Ways to Address Brightness

LED display Manufacturers use various strategies when handling high brightness issues:

LED Replacement:

LED display Manufacturers can replace standard LED chips with ones tailored specifically towards higher brightness LED displays such as SMD3535 LED chips, which offer greater brightness capabilities.

Automatic Brightness Adjustment:

LED displays Control cards can be programmed to automatically adjust brightness according to environmental factors, including ambient light sensors that help measure levels and control brightness accordingly. This feature helps decrease viewer glare.


LED display screens have completely revolutionised our visual landscape, but many misunderstand that greater brightness equates to better quality. There must be an equilibrium between brightness and energy efficiency which must be preserved; ideal brightness levels, consideration for any unwanted consequences caused by excessive brightness levels, as well as commitments made towards environmental responsibility are all crucial aspects in LED displays’ success.
