In recent years, LED display applications in outdoor areas, more and more involved in the industry are increasingly being used, especially particularly prominent in outdoor advertising, a lot of advertising media have means of LED displays this card to expand its share and enhance the company's brand influence on the advertising market. In practice, LED full color display life, is a direct impact on corporate investment return cycle. In order to shorten the payback period, improving gross profit, we must understand and master the following seven LED display maintenance of common sense. First, switch the order. When the display is turned on, first turn on the computer, after the opening screen. When closing the display: first off-screen, turn off the computer after the (first off the computer does not turn off the display, the screen will cause the body with high bright, burning lamps, serious consequences.) Switching screen time intervals greater than 5 minutes. After the computer into the project control software before opening screen power. Second, to avoid possible problems encountered, we can choose a passive protection and active protection, as far as possible on the outdoor LED screen may damage the items curtain away from the screen, but also wipe clean the screen when gently as possible, the damage minimize the possibility of. Third, outdoor LED display relationships with our customers most closely and do cleaning and maintenance work is also very necessary. Prolonged exposure to the outdoor environment wind, sun, dust and so easy to show the dirt, some time down the dust on the screen is certainly one, which requires timely cleaning surfaces to prevent dust affect long wrapped viewing. Fourth, often display the power switch to trip, should be checked Screen LED unit board or replace the power switch. Display of power is very important, because the power under different temperature conditions, the stability of its work, the output voltage and load capacity will be different, because it bears a logistical role, so it's guaranteed the ability to directly affect the Quality screen. Fifth, the screen body prohibited water, iron and other metal objects that conduct electricity easily. Outdoor LED Display try to be placed in low-dust environments, the dust will display a large impact, but excessive dust will damage the circuit. If the water for various reasons, please power off immediately and contact maintenance personnel, until the screen displays the body panels and dried before use. Six, the proposed outdoor LED display for longer than two hours a day of rest, with the boot time and the outside temperature, the thermal drift of components will increase, resulting in poor picture quality. In the rainy season, outdoor LED display using at least one week more than once. Usually at least a month to open the screen once, lit more than two hours. This is done in order to remove moisture and prevent moisture dead light lamp beads, SMD surface mount display particular attention. Seven, do not be in a long while playing all white, all red, all green, all bright blue and so the whole picture, so as to avoid excessive current, power line fever is too large, LED light damage, interfere with the monitor life.
