Outdoor Full-color Display Screen PH20

Description

outdoor full-color LED displays have special technology. All the lamps are arranged in vertical line and horizontal line. All the lamps can stand vertically (or with the same angle) on the PCB. The luminance dots are distributed uniformity to avoid a “black hole”. We make the whole produce process under the anti-static control, to prevent the harm of static and reduce the rate of burning out. At present, the dead dot rate of our outdoor LED display can be controlled within 1/*0, *****, we can sure the rate of brightness difference less than 1:1.2. It means the luminance difference for any two lamps are less than *0%. So, the luminance and color of whole screen are uniformity. Besides, Liangjinjing outdoor full-color LED display have the following advantages, compared with others: 1.Liangjinjing use high quality imported silica gel, which have a excellent capability of waterproof, anti-freeze and anti-high temperature etc. 2.Liangjinjing outdoor full-color LED display passed the test of waterproof and dustproof, which Passed IP*5, and some items pass IP*7. 3, Liangjinjing outdoor full-color LED display was test by Shezhen Academy of Metrology and Quality Inspection. The result shows: our LED display can be used under the temperature of ï&frac*4;*5℃ till ï&frac*4;‹*5℃. ***** are arrises on the bottom of modules, which have a good capability to stand pressure, then can keep smooth for each cabinet. ***** is a slip steel sheet on the upside of our cabinet, and a runner on the bottom side of our cabinet, which can be adjusted to shorten the gaps of two cabinets. Then keep the smooth of whole LED display.
