The technique of full color LED electronic screen body protection

LED Electronic display system touched by the products are anti-acid rain, salt spray, waterproof, moisture, dust, anti-incineration, anti-corrosion and other disposal, after salt spray experiment, the results show that: The products are reached the national industrial norms, in accord with the requirements of salt fog test, even under the conditions of oceanic climate, The screen can also be used for a long time. Below, chip photoelectric for you to analyze how to protect the screen body of LED large screen?

One, the LED screen protection embodies in the following aspects: 1, LED screen system screen in the body of the anti-corrosion function is very good flame retardant material high-quality aluminum-plastic plate manufacturing, between the plate stitching tight filling high-quality weathering gum. 2, LED screen system between the pixel and the module with insulating rubber ring seal to prevent moisture infiltration. 　　3, embellishment and module between the seam filled with foam bar and filled with high-quality weather-resistant adhesive, to prevent moisture ingress.  second, the protection of the LED screen: 1, the use of 30,000 hours after the screen body brightness attenuation of about 15% (factory brightness), at the moment the screen stamina reached the highest brightness of about 1500cd/m2; At this point, manual re-set the maximum operating brightness of the screen 90-100% ups and downs. 2, led electronic display factory, the screen body brightness is set to 2500cd/m2 above, the device after commissioning, manual set full color display screen body maximum operating brightness of the factory 70%, about 1800cd/m2. 3, because of the noise and the quantization of the analog-to-digital conversion of the preamble, which greatly affects the video appearance of the LED display, it is necessary to adopt a certain noise reduction disposal method. Our company used large-scale programmable integrated circuit to develop a recursive and median filtering function of the LED control system, very good to improve the full color screen video picture of the role of appreciation.
