三、the key parameters of LED display signage board

1. Pixel pitch: Pixel pitch is a key factor in determining resolution and optimal viewing distance. It refers to the distance between the pixels of the LEDs led board, which has a direct impact on the resolution and visual effect of the screen led sign board. The smaller the pixel pitch, the more detailed the picture and the better the viewing experience. At the same time, the smaller pixel pitch results in higher resolution and ensures that the picture is clearly visible.

2. Brightness: Brightness is the core indicator to measure the brightness of the screen display, measured in nits (cd/m²). It directly determines the clarity and visibility of the display in different lighting conditions. Sufficient brightness can ensure that the screen can present a clear and vivid picture in various environments, meeting the viewing needs of different scenes.

3. Viewing angle: The viewing angle refers to the clarity of the image when viewing the display from different angles, including horizontal and vertical viewing angles. The wide viewing angle ensures that the image remains clear when viewed from multiple angles.

4. Refresh rate: The higher the refresh rate, the smoother the dynamic image display and avoid ghosting and blurring. The refresh rate indicates the number of times the screen is updated per second, a parameter that is critical to the smoothness of the moving image. The high refresh rate ensures that images remain smooth and natural even at high speeds.

5. Gray level: The gray level affects the depth and delicacy of the color, and the common ones are 8 bits, 10 bits, 12 bits, etc. High gray levels allow for a richer color gradation.

6. Power consumption: Measured in watts (W), power consumption directly affects the operating cost and heat dissipation design. The low-power design helps reduce long-term operating costs and improve energy efficiency.

四、the field of application

Advertising media: large outdoor billboards, commercials. In commercial centers, stations, airports and other places, it is used to broadcast advertisements and promotional information.

Public places: information display at airports and stations.

Stage art: stage background for concerts and theaters. Provide gorgeous backdrops and visuals for the stage.

Sporting events: Large-screen displays at the game site. Display scores, athlete information, and more at the stadium.

Traffic instructions: used for information prompts in the field of transportation such as highways and railways.

五、 Selection and Purchase

1. Determine the usage scenario: First clarify whether the LED wall panel display will be used in an indoor or outdoor environment, as well as the expected viewing distance. This will help you determine the desired screen size and resolution. Indoor environments often require higher pixel density and color performance, while outdoor environments may require higher brightness and better protection.

2. Pixel density selection: pixel density, that is, the size of the pixel pitch, directly affects the clarity of the display effect. The smaller pixel pitch is good for close viewing, but it costs more. Choose wisely according to viewing distance and budget, and avoid over-investing in unnecessary high definition.

3. Brightness requirements: Choose the appropriate brightness level according to the light conditions at the location of the display. Indoor displays may not require high brightness, while outdoor displays must be bright enough to resist sunlight.

4. Budget considerations: Create a reasonable budget and consider long-term operating costs, such as energy consumption and maintenance expenses. Choosing cost-effective products can save costs while maintaining quality.

5. Maintenance costs: Understand the maintenance costs of different brands and models, including energy consumption and ease of repair services. Choose products that are easy to maintain and have low long-term operating costs.

6. Quality comparison: Compare the performance, price and user evaluation of different brands and models. Choose brands that have a good reputation and offer reliable after-sales service.

7. Evaluate supplier reputation: Choose suppliers with good market reputation and high-quality after-sales service. A good supplier can ensure the quality of the product and provide the necessary support in case of problems.

8. On-site testing: If possible, schedule a live demonstration or request samples for a first-hand assessment of the product's performance and quality. Seeing your display in action can help you make more informed decisions.

六、Installation and maintenance

1. Professional installation: Installing LED displays is a highly technical job that should be done by experienced professionals. Proper installation and commissioning is not only related to the stability and safety of the screen, but also directly affects the display effect and the reliability of long-term operation.
