Precautions For Outdoor Dooh LED Display Installation
December 6, 2022
The following points should be paid attention to when installing outdoor LED display.
1. Lightning protection equipment shall be installed on display screen and building
The display screen is likely to suffer from the siege of weak current and strong magnet caused by lightning strike, so the main body and shell of the display screen maintain a stable grounding device, and the resistance of the grounding wire is lower than 3 ohm bus, so that the large amount of current caused by lightning strike can be discharged immediately.
2. Waterproof and moisture-proof
Outdoor LED display screen is in a complex environment. When installing, the problem of waterproof and moisture-proof should be considered, and the display screen should have a good drainage pipe.
3. Install ventilation and cooling equipment
When the display screen is running, it will generate a certain amount of heat. If the working temperature is too high and the heat removal is not good, the electronic devices are likely to work abnormally, or even be damaged, so that the display screen cannot work normally. Therefore, it is necessary to install ventilation and cooling equipment to keep the internal temperature of the LED display screen within a reasonable range.
To improve the display effect of LED display screen, we can start from the following aspects:
1、 Reduce the dot spacing of full-color LED display
Reducing the dot spacing of full-color LED display can improve the clarity of the display, because the smaller the dot spacing is, the higher the pixel density per unit area of full-color LED display is, the more details can be displayed, and the more delicate and lifelike the picture display
2、 Improve the contrast of full-color LED display
Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and lifelike the image, and the brighter and gorgeous the color. High contrast is very helpful for image clarity, detail performance and gray level performance.
3、 Improve the gray level of full-color LED display
The gray level of LED display screen refers to the single primary color brightness from the darkest to the brightest, which can distinguish the brightness level. The higher the gray level of full-color LED display screen is, the richer the color is, and the more gorgeous the color is; On the contrary, the display color is single and the change is simple. The improvement of gray level can greatly improve the color depth of LED large screen, and make the display level of image color increase geometrically. Now many full-color LED display manufacturers can realize the gray level of the display screen of 14bit~16bit, so that the image level can distinguish details and the display effect is more delicate, lifelike and colorful.
4、 Combination of full-color LED display and video processor
LED video processor can use advanced algorithms to modify the signals with poor image quality, and carry out a series of processing, such as separation, edge sharpening and motion compensation, in order to improve the details of image display and improve the quality of image display. The video processor image shrinkage processing algorithm is adopted to ensure that the image clarity and gray level are maintained in shrinkage. The video processor needs rich image adjustment options and adjustment effects to process the image brightness, contrast and gray level, so as to ensure that the full-color LED display screen outputs soft and clear pictures
