LED Screen Parameters: A Guide For You

This article will explain the various parameters of an LED screen. It includes brightness, color temperature, Ingress Protection, and refresh rate.

We will also share with you why these factors must have the proper levels on each device and how such adequate parameters can make an LED screen low quality and give you tips on maintaining these parameters.

What Are The LED Screen Parameters?

The LED screen parameter pertains to the different variables and measures that directly affect the performance and quality of the LED screen. These parameters vary in measurements and levels.

LED Screen Production

The overall visual effect of the screen relies on more than just the quality of the components. It is also on having the proper levels of parameters. And as a buyer, you must know firsthand before your significant LED screen purchase. 

This article will tackle standard parameters: brightness, IP rating, color temperature, and refresh rate. 

Brightness And Brightness Adjustment

The LED screen brightness plays a significant role in determining whether the device is suitable for indoor or outdoor use and is a crucial choice for LED displays. 

Brightness for LED displays refers to the screen’s luminous intensity per unit area when it is usually working. We express it as cd/m² or nits.

The higher the brightness, the brighter the image becomes and the sharper it will look from a distance. However, it is not always necessary to have high brightness LED screen, so its level always depends on the LED screen’s type of use. 

Brightness is one factor challenging to measure but can also be measured by professional tools. 

LED Screen Parameters

If we compare the two main types of LED screens, the indoor and outdoor, the outdoor LED screen comes brighter. In many cases, indoor LED screen only reaches 1000 nits as the maximum, while outdoor screens can reach up to 7000 nits. It is because outdoor LED screens are installed under direct sunlight, and the high brightness makes the content visible even under the terrific sunlight. 

In most cases, LED screens come with adjustable brightness levels, which include Colorlight-LED displays. The brightness adjustment refers to the LED display setting that allows brightness adjustment from lowest to highest. While an LED screen’s maximum and minimum brightness is already fixed during production, brightness adjustment is still necessary. It helps tone down, brighten the device, and curate with the light in the environment. 

LED Screen Color Temperature

Upon the display’s finished manufacturing, it undergoes aging and display tests. In the display test, engineers and technical experts measure the brightness of red, green, and blue. They must accurately level these colors to restore the color. When red, blue, and green colors are not balanced, the white color may turn pink on the screen. This also affects other color properties of the LED screen. 

We call the process white balance, which includes repetitive brightness checking to get the right and accurate white color. 


The grayscale refers to the degree of brightness. It is also known as half-tone and is used mainly to transmit pictures. Also, it has three methods which are the following; 16, 32, and 64 levels. It applies a matrix procedure to process the file’s pixels into 16, 32, and 64 levels to help transmit and clarify the photo or content. 

A quick takeaway is that the higher the grayscale level, the richer and brighter the color becomes, and with a low grayscale, the less attractive the visual pigment. 

Ingress Protection

Ingress protection or IP rating is the degree of protection that a mechanical or electronic enclosure or equipment has against solid bodies and liquid penetration. It is also referred to as the waterproof level or dut-proof level. 

In most cases, indoor LED screens have a lower IP rating than outdoor equipment. Indoor LED screens can have IP45, which is enough for its type of environment. However, outdoor LED screens must meet at least IP65 or even higher, depending on the environment’s harshness. 

In reading the rating, below is a figure to help you. 




Protection is from objects greater than 50mm in diameter.

 (Example: Hand)



It has protection from condensation and vertically falling drops of water. 

Protection from things greater than 12.5mm in diameter. 

(Example: Fingers)



It has protection against water drops with an enclosure tilted up to 15 degrees from the vertical. 

Protection from entry by objects with a diameter of 2.5mm or more. 

(Example: Tools, Screwdriver)



Against spraying water up to 60 degrees from the vertical. 

Protection against foreign bodies is more significant than 1mm.

(Example: Small tools, Wire)



Against water spray and splashes from all directions. 

Dust protected. Limited ingress of dust permitted. It will not interfere with the operation for 2 to 8 hours. 



Protection against low-pressure jets. Limited ingress permitted. 

It is completely isolated from dust. Dust tight. 2 to 8 hours.



Protection against high-pressure water jets. 



Temporary immersion in water between 15cm and 1m for 30 minutes.


Protection against immersion in water over long periods. 

Refresh Rate

Refresh rate or refresh frequency refers to the image update speed on the LED screen. It is an important indicator that shows the stability of the LED display. The higher the refresh rate, the more stable the display device is. We measure it in Hz or Hertz. 

Generally, LED screens have around 300-600 Hz, but with Colorlight-LED, our LED screens reach up to 1920 and even 3840 Hz. 

LED screens have many parameters; some are more complicated to understand due to different measurements. But these five parameters we mentioned are the most common ones you need to consider upon purchase.
