How to choose an outdoor led screen?4 aspects for reference

How to choose an outdoor led screen? When choosing an outdoor LED screen, you can consider it from the following aspects:

1. Technical parameters

Pixel pitch
Definition: Pixel pitch refers to the distance between the center points of two adjacent pixels on the LED screen, usually expressed in millimeters (mm).
Impact: The smaller the pixel pitch, the higher the resolution of the display and the clearer the image. For outdoor applications, the appropriate pixel spacing needs to be selected based on the viewing distance.
Selection suggestions:
If the viewing distance is far (such as more than 10 meters), you can choose a display with a large pixel spacing, such as P8, P10, etc., which can meet the viewing needs and reduce the cost.
If the viewing distance is close (such as within 5 meters), you should choose a display with a smaller pixel pitch, such as P4, P3, etc., to obtain higher clarity.

luminance
Brightness refers to the luminous flux emitted by the display in a unit area, usually expressed in Candela per square meter (cd/m²).
Impact: The outdoor environment light intensity changes greatly, the display with insufficient brightness may not be able to see the image under strong light, and the brightness is too high, which may cause dazzling and energy waste.
Selection suggestions:
In general, the brightness of the outdoor LED screen should be above 5000cd/m² to ensure that it can be clearly displayed in the sun.
If the display is installed in direct sunlight, or the ambient light is very strong, you can choose a higher brightness display, such as 7000cd/m² or above.

Visual Angle
Definition: Angle of view refers to the range of angles that the display can be clearly seen in different directions.
Impact: A larger viewing Angle allows more viewers to see a clear image in different locations.
Selection suggestions:
Outdoor display should have a large horizontal and vertical Angle of view, the general requirements of horizontal Angle of view ≥120°, vertical Angle of view ≥100°.
If the display is mounted at a height or needs to cover a larger viewing area, you can choose a display with a larger viewing Angle.

Contrast
Definition: Contrast is the ratio of brightness between the brightest and darkest parts of a display.
Impact: High contrast can make the image more vivid, vivid, more colorful.
Selection suggestions:
The contrast ratio of the outdoor LED screen should be above 3000:1 to obtain a good image effect.
Contrast can be assessed by looking at the technical specifications of the display or by actually looking at a sample.

2. product quality

Class of protection
Definition: Protection level refers to the display’s ability to protect against external environmental factors such as dust and water.
Impact: The outdoor display needs to have a high level of protection to prevent dust, rain, sunlight and other damage to the display.
Selection suggestions:
The protection level of the outdoor LED display should generally reach more than IP65, that is, it can completely prevent dust from entering, and can withstand the impact of low-pressure water spray.
You can check the display’s product manual or certification to determine the level of protection.

Heat dissipation performance
Definition: Heat dissipation performance refers to the ability of the display screen to dissipate heat during operation.
Impact: Good heat dissipation performance can ensure that the display will not be damaged because of high temperature when working for a long time, and can also extend the service life of the display.
Selection suggestions:
Choose a display with a good heat dissipation design, such as using heat sinks, fans and other cooling methods.
You can ask the manufacturer about the heat dissipation performance and operating temperature range of the display.

stability
Definition: Stability refers to the reliability and stability of the display screen in long-term work.
Impact: Unstable display may fail, such as black screen, flicker, flower screen, etc., affecting the use effect.
Selection suggestions:
Choose displays made by well-known brands and manufacturers with a good reputation, which usually have stricter quality control and more reliable products.
You can view the manufacturer’s qualification certificate, product testing report, etc., to understand the quality and stability of the display.

Service life
Definition: The service life refers to the time that the display is able to work normally.
Impact: Long service life display can reduce the cost of replacement and maintenance, but also can ensure long-term use effect.
Selection suggestions:
The service life of outdoor LED screen should generally be more than 50,000 hours.
You can understand the brand and quality of key components such as the light source and driver chip of the display screen, which directly affects the service life of the display screen.

3. Service and support

Manufacturer’s reputation
Choose a manufacturer with a good reputation, you can evaluate by looking at the manufacturer’s qualification certificate, customer evaluation, industry reputation and other ways.
Reputable manufacturers are usually able to provide more reliable products and better service.

After-sales service
Understand the manufacturer’s after-sales service content, including warranty period, repair response time, technical support, etc.
Good after-sales service can ensure that the display can be solved in time when problems occur during use.

Training and support
Some manufacturers will provide training and technical support for the installation, commissioning, operation and other aspects of the display screen, which is very important for users.
Ask if training and support services are available.

4. Price and cost

Display price
Different brands, different specifications of outdoor LED display prices vary greatly, you need to choose according to your budget and needs.
When comparing prices, we should pay attention to the comprehensive consideration of the quality of the display, performance, after-sales service and other factors, do not only look at the price and ignore other important aspects.

Installation and maintenance costs
The installation and maintenance of outdoor screen requires a certain cost, including installation costs, electricity costs, maintenance costs, etc.
When choosing a display, consider these cost factors and choose a display with lower installation and maintenance costs.

Operating cost
The operating costs of the display include electricity, network costs, content production costs, etc.
Energy-saving display can be selected to reduce electricity costs; At the same time, choose a display that is easy to operate and manage, reducing content production and operating costs.

In short, the selection of outdoor LED screen requires comprehensive consideration of technical parameters, product quality, service and support, price and cost and other aspects, according to their actual needs and budget to choose, in order to obtain the best use effect and return on investment.
