What are the requirements and precautions for LED display installation?
1.led electronic advertising screen and the installation of lightning protection devices on the building. The display body and the shell to maintain a good grounding, LED Panel grounding resistance is less than 3 ohms, so that lightning caused by high-current discharge in time; the display may be caused by lightning strong magnetic attack.
2. Screen body and the screen body and the combination of the building must be strictly waterproof and leakproof; screen body should have a good drainage measures, once the occurrence of water can be discharged; pay attention to water, moisture. The display is installed outdoors, often sun and rain, wind and dust cover, working environment is bad. Electronic equipment is damp or severe damp will cause a short circuit or even fire, causing failure or even fire, causing losses;
3. Selection of the working temperature of -40 ℃ ~ 80 ℃ between the industrial-grade integrated circuit chip to prevent the winter temperature is too low to lead electronic advertising screen can not start.
4. Install the ventilation equipment cooling, LED Panel so that the internal temperature of the screen between -10 ℃ ~ 40 ℃. The upper part of the body behind the installation of axial fan exhaust heat; led electronic display work itself will produce a certain amount of heat, if the ambient temperature is too high and poor heat, the integrated circuit may work is not normal, or even burned, so that the display system can not work normally;
5. In order to ensure that the ambient light in the case of long-distance visual, you must use ultra-high brightness light-emitting diodes; increase the contrast. Wide audience, wide viewing distance, wide field of vision requirements; ambient light changes, especially possible by the sun Direct.
6. Display medium selection of a wide range of wide viewing angle tube, wide viewing angle, pure color, consistent coordination, life of more than 100,000 hours display medium outer package for the most popular with a square tube, silicone seal, no metal assembly; Sophisticated appearance, LED Panel durable, with anti-sun direct, dust, water, high temperature, anti-circuit short circuit five anti-characteristics.
Previous: LED electronic display in the procurement of errors
LED display performance superior:
1) light intensity, in the visual distance within the direct sunlight on the screen surface, the display is clearly visible. LED Panel Super grayscale control with 1024-4096 gray-scale control, display color 16.7M or more, clear and realistic color, three-dimensional sense of strong.
2) static scanning technology, the use of static latch scan, high-power drive, fully guarantee the luminous brightness.
3) automatic brightness adjustment with automatic brightness adjustment function, in different brightness environment to get the best playback.
4) the full use of imported large-scale integrated circuits, greatly enhance the reliability, easy to debug maintenance.
5) advanced digital video processing, technology distributed scanning, BSV LCD splicing technology HD display, modular design / constant current static drive, brightness automatic adjustment, ultra-bright solid pixels, image clear picture, no jitter and ghosting, Eliminate distortion. Video, animation, charts, text, pictures and other information display, networking display, remote control.
LED color and process manufacturing LED material is different, can produce a different energy of the photon, which can control the LED emitted by the wavelength of light, that is, the spectrum or color.
LED display classification of a variety of, generally in accordance with the following ways:
(1) according to the use of the environment divided into indoor, outdoor and semi-outdoor
Indoor screen area is generally less than 1 square meters to ten square meters, indoor LED display in the indoor environment, such display brightness is moderate, large viewing angle, color mixing distance, light weight, high density, suitable for closer viewing The
LED Panel Outdoor screen area is generally from a few square meters to dozens or even hundreds of square meters, the point density is more dilute (mostly 2500-10000 points per square meter), luminous brightness in the 5500-8500cd / square meter (towards different, different brightness requirements), in the sun Direct use of the conditions used to watch the distance in the tens of meters away, the screen body has a good wind and rain and lightning protection capabilities.
Semi-outdoor screen between the outdoor and indoor between the two, with a high luminous brightness, can be used in non-sun direct outdoor use, the screen body has a certain seal, LED Panel generally under the eaves or window.
(2) by color is divided into monochrome, double color, three primary colors (full color)
Monochrome refers to the display only one color of the luminescent material, mostly single red, in some special occasions can also be used yellow-green (such as funeral home).
Dual-color LED display consists of red and green LED lights, 256 gray-scale dual-color display can display 65,536 colors (two-color screen can display red, green, yellow 3 colors).
The full color LED display consists of red, green and blue LED lights, which can display white balance and 16,777,216 colors.
