Technology | Is Brighter Always Better? A Comprehensive Guide to Selecting the Right LED Display Brightness

 In the LED display industry, there is an endless list of professional terms such as brightness, refresh rate, contrast ratio, and gray scale. How much do you know about them? Is it true that the higher the brightness of an LED display, the better? This article will tell you how to choose the right LED display brightness.

What is the "Brightness" of an LED Display?

The brightness of an LED display refers to the luminous intensity per unit area in the normal direction (vertical direction) of the display, and it is measured in nits (1 nit = 1 cd/m²). For example, if there are 1,000 light-emitting diodes (LEDs) on a 1 m² LED display, and the brightness of each LED is 5 candelas (cd), then the brightness of this screen is 1,000 × 5 cd/m² = 5,000nits.

Why is the "Brightness" Parameter So Crucial?

Brightness directly determines the visible distance of the display, its adaptability to different environments, and the efficiency of information transmission. The "minimum brightness requirements" vary depending on the viewing distance and environment.

Brightness has a direct impact on the user's viewing experience. Excessively high brightness can cause eye dryness and fatigue, while insufficient brightness can lead to a decrease in color saturation and affect the authenticity of the image.

As the brightness of the display increases, the power consumption also rises accordingly. Moreover, long - term operation at a high brightness beyond the rated capacity will accelerate the aging of the LEDs. A reasonable selection and design of brightness can save energy, protect the environment, reduce costs, and extend the lifespan of the display.

*Note: Brightness is just one of the key factors affecting the display quality, viewing experience, and lifespan of an LED display. In practical applications, other factors should also be considered comprehensively.

How to Choose the "Brightness" of an LED Display?

Analyze the Usage Environment

For outdoor environments with strong sunlight, it is recommended that the brightness be ≥ 6,000 nits to ensure that the content is clearly visible even under direct sunlight. For semi - outdoor environments (such as under a rain shelter or in a showcase), a brightness of 2,000 - 4,000 nits can achieve self - adaptive adjustment under various lighting conditions. For indoor environments (such as exhibitions, conferences, and product launches), a brightness range of 600 - 1,500 nits can meet regular requirements.

Flexible Brightness Adjustment

In the rental industry, the adjustability of brightness is particularly important. LED displays are equipped with precise dimming systems, as well as technologies such as wide color gamut, high contrast ratio, and high refresh rate. This allows for flexible brightness adjustment in response to changes in ambient light and different viewing requirements, ensuring a balance between brightness and image quality and reducing procurement and operation costs.
