Desciption:
Field visits and testing the quality of outdoor LED screens is a meticulous and comprehensive process that involves multiple aspects of evaluation. Here are some key steps and takeaways:
1. Appearance detection
Surface inspection: Check whether the surface of the LED screen is flat, no damage, no rupture and other physical defects. The surface should be smooth, no obvious scratches, stains or cracks.
Structural integrity: Check whether the border, fixing screws, plugs, etc. of the LED screen are tight, and there is no loosening or damage. At the same time, observe whether the modules, connectors and other components are firm to ensure the integrity of the overall structure.
Second, display effect detection
Brightness and uniformity: Use a luminance meter to measure the brightness of the LED screen to ensure that it meets the design requirements, and the brightness is uniform, no obvious difference between light and dark. For outdoor LED screens, the brightness should generally be higher than 6000nit to ensure that it can be clearly displayed in a strong light environment.
Color reducibility: The colorimeter detects the color reproduction performance of the display screen to ensure that it can accurately present the color of the image. The proportion of the three primary colors, red, green and blue, should be appropriate to avoid color distortion.
Viewing Angle: Detect the visibility of the LED screen at different angles, including horizontal and vertical viewing angles. The horizontal Angle of view of the outdoor LED screen should be greater than 100 degrees, and the vertical Angle of view should be greater than 90 degrees to ensure that the audience can clearly see the screen content in different positions.
Contrast: The contrast of the display is measured by optical instruments, and high contrast can provide a clearer and transparent image. The contrast value should not be lower than 1000:1.
Refresh rate: Measure the refresh rate of the LED screen, and a display with a high refresh rate can present a smoother picture and reduce flicker. For outdoor LED screens, the refresh rate should not be less than 300Hz.
Third, functional testing
Power testing: The power consumption of the display is measured by a power meter to assess its energy efficiency and operating costs.
Stability test: Run the display for a long time to detect whether there are dead spots, flickering and other problems to ensure its stability in long-term use.
Waterproof performance: For the LED screen used outdoors, it is necessary to perform a waterproof test to ensure that it can work normally in rain and snow weather.
Fourth, environment and adaptability testing
Temperature and humidity adaptability: The performance of the display under different temperature and high humidity conditions is tested through the high and low temperature test chamber and the wet and hot test chamber to ensure that it can still work normally in extreme environments.
Vibration and shock testing: The vibration and shock resistance performance of the display screen is tested by shaking tables and impact test equipment to ensure that it is not damaged during transportation and use.
5. Other tests
Aging test: The display screen is continuously run at high temperature and full load for a certain period of time to observe its performance changes and evaluate its long-term reliability.
Communication performance test: Detect the stability and transmission rate of the communication signal of the display screen to ensure that it can receive and display content in various formats stably.
6. Professional instrument testing
Pixel detection: The use of professional pixel detection equipment for comprehensive detection and analysis of the display screen, to observe whether there are uneven brightness, dark spots, bright spots and other problems.
Color and grayscale detection: By sending different types of images and video content to the display screen, detect its color purity and grayscale level to ensure that its display effect is delicate and layered.
In summary, field visits and tests of the quality of outdoor LED screens need to consider the appearance, display effect, function, environment and adaptability. Through professional instruments and scientific testing methods, the quality and reliability of the LED screen can be comprehensively evaluated.
