What Brightness Is the Most Suitable for Your LED Display?
Choosing an appropriate brightness for your LED screen is a very important point for bring the viewer a greater viewing experience. If the screen is too bright, the viewer will feel uncomfortable, but if the screen is too dark, the visibility of content will be greatly reduced. Here is a simple guide to choose a suitable brightness for your LED screen.
500-8000cd/m²: the most common brightness for indoor LED displays (TV screens, computer monitors, etc.).
800-1500cd/m²: suitable for indoor LED displays installed in bright indoor environments or in direct sunlight.
4,000-5,000cd/m²: the most common brightness for outdoor LED displays.(Wall screen,pole screen,highway screen,etc.).
≥5,000cd/m²: suitable for outdoor LED displays installed in high-light outdoor environments.
Why Adopt the Outdoor LED Display for Indoor Use?
The common indoor LED display’s brightness is only 800-100cd/m². If your display needs to exposed to direct sunlight to display the image, then the general indoor display brightness cannot meet the display requirements. At this point, you gonna need to choose a high-brightness outdoor screen. Otherwise, the screen will be too dark, and the image on the screen is simply not visible.
High Brightness＝High Performance?
No, high brightness≠high performance. The high brightness may means light pollution.
Generally speaking, the brightness of the sun is 2000cd/m². If the brightness exceeds twice the brightness of the sun, the naked eye will feel uncomfortable when looking directly at it. If the brightness of the outdoor LED display exceeds 5000cd/m², it will be defined as the light pollution.
On the other hand, some of the LED billboards on the street are very close to the traffic lights. At night, some of the display screens are very similar to traffic lights. Drivers mistakenly believe that they are driving forward with green lights, which can easily cause traffic accidents.
To solve the problems brings by light pollution, we recommend adopting the light sensor for the outdoor LED display to adjust the light conditions. It can adjust the brightness of the screen automatically according to the environment brightness.
This solution provides important advantages such as:
- Improve LED life by 20-30%;
- Save the LED display power consumption;
- Comfortable image perception in any weather conditions;
- Improve the safety of the passerby (will not blind drivers and pedestrians);
- The screen brightness is automatically controlled without manual input.
What Kind of Display Effect Is Right for Your LED Sign?
If you want to know the display effect, you must to know the best point is Pixel pitch, refresh rate. More details as following:
How to Choose Pixel Pitch?
LED display pitch refers to the distance between the light-emitting source point and the point, usually in millimeters. By determining the optimal viewing distance of the screen, we can determine the pixel pitch value of the LED screen.
You can determine the pixel pitch value of the LED screen according to the installation position of your display and the appropriate viewing distance. Thereby choosing the right product.
It’s worth noting that the appropriate viewing distance refers to the range of image fidelity. If the observer is too close, the image quality will be reduced or the screen will appear pixelated.
Simply put, a smaller pixel pitch can provide a higher quality image, but if the screen is far from the viewer, there is no need to make additional cost investment in pursuit of a small pitch. Considering the outdoor advertising LED screen, they are often installed at a distance of more than 5 meters from the ground, we will suggest that you can choose P8 or P10.
Why a Good Visual Effect Does Not Necessarily Require High Refresh?
The refresh rate refers to the speed at which the image is updated on the LED display, that is, the number of times the image on the screen appears per second, and its unit is Hertz (Hz).
The higher the refresh rate, the smaller the flicker of the screen on the led display, the higher the stability, the better the protection of eyesight, and the more comfortable viewing experience. The lower the refresh rate, the more flickering and shaking the image, and the faster the eyestrain.
Generally speaking, if the refresh frequency can reach above 80Hz, the image flicker and shake can be completely eliminated, and the eyes will not be too tired.
The refresh rate of our regular LED display is 1920HZ, usually this refresh rate can meet our normal needs, but for some demanding places such as LED rental displays, LED small-pitch displays, viewers will use mobile phones or video equipment shoots the screen, so a high refresh rate of 3840 Hz is generally required to meet the usage requirements.
The most important point is that if the viewing distance is greater than 10 meters, there is no difference between 1920 refresh and 3840 refresh. So don’t think of good visual effects, you must choose high refresh.
How to Choose the Suitable Maintenance Method According to the Installation Position?
1) Front maintenance :
For inlaid or video wall installation environment, space is extremely precious, so there will not be too much room left as a maintenance channel. Then the Front service is necessary.
The front-maintained display screen is thin, does not occupy space, saves materials, is light in weight, and is easy to install. It is suitable for installing wall mount.
2) Rear maintenance:
When the installation space behind the LED billboard is large, the post-maintenance method is equally efficient. The Rear Service design is more convenient and efficient for installation scenarios such as roof type and column type. In addition, for some large-scale LED display installed on the outer walls of buildings. Maintenance channels must be designed so that maintenance personnel can perform efficient service and repairs from the back of the LED screen.
What Kind of LED Cabinet Is the Most Suitable for Outdoor Advertising LED Display?
For outdoor advertising LED screen, there is no doubt that waterproof and dustproof are necessary conditions. As for the use environment of different LED Billboard, the requirements for waterproof and dustproof are also different. These are all measured by IP stand. Details information are as below:
Usually, for indoor LED Cabinet: IP30/IP43/IP54; For Outdoor LED Cabinet: IP65.
If it is a perennial stormy area, we recommend IP68.
In addition to ordinary waterproof LED screen, some LED panel are used in extreme weather, and their requirements for cabinets and cables will also change accordingly. For example:
1) High temperature area: Steel Cabinet, High temperature professional cables.
2) Low temperature area: Steel Cabinet, Low temperature professional cables.
3) Seaside high-salt area: Aluminum Cabinet, Anti-corrosion professional cables.
How to Achieve Real-time Monitoring of LED Screen?
In order to solve the impact of screen display failure in time, and related factors such as anti-theft and anti-theft, a large part of customers will require the installation of a monitoring system for the screen.
But before we answer this question, you need to know “What system you use to control the screen?” There are usually two ways to control the operation and display of the LED billboard: synchronous system and asynchronous system. Based on the different control methods, the real-time monitoring of the screen will be different:
Monitoring System for LED Display
Common Control software
Novastar/LINSN/Colorlight and so on
Novastar/Huidu/Xixun/Colorlight and so on
Independent monitoring system
(Camera + Supporting software)
Internal monitoring system in control software or Monitoring system based on Camera + control software
Customer Case Analysis
