affect the LED display life of reason analysis and extend the method


1, the LED display screen, belonging to the semiconductor device, so it requires that the room temperature 25 degrees Celsius when working mechanism is the best. But in reality, it is difficult for us to do this, the summer pit 40 degrees Celsius, winter and -30. At this time, the work efficiency of the LED display and performance will be inconsistent. This is because the brightness of the red, green and blue three lights in different temperature conditions brightness decay and decline is different, at 25 DEG C, the white balance is normal.

2, switching sequence. Open the screen, first open the computer, after the peacock. Turn off the screen when: first off screen, after the computer screen, the computer does not turn off the screen, it will cause the screen appears high highlights, burn the tube, the consequences are serious. Switch screen time interval to be greater than 5 minutes. The computer control software into the project, can spread electricity. Avoid the peacock white screen in full screen mode, because the impact of current at the maximum. To avoid out of control under the tail, because the impact of current at the maximum. HERSHEY'S is not the ambient temperature is too high or cooling conditions, should be careful not to long time tail. The electronic screen body part line appears very bright, attention should be paid to off screen, not a long time to spread in this state. Often appear on the screen of the power switch trip, should be timely check the LED unit board screen or replace the power switch. Regularly check the firm condition of the joint. If there is a loose phenomenon, pay attention to the timely adjustment, re reinforcement or renewal of hanging pieces. According to the large screen display screen, the control part of the environmental conditions, avoid insect bites, when necessary, should be placed on anti poison.

3, power is also very important, due to power under different temperature conditions, the working stability of the output voltage, value and load capacity will vary, because it bears the function of the logistics, so its support capability directly affect the screen quality.

4, regularly check the virus, remove irrelevant data. To master the control parameters of the settings, the basic data of the pre modified, familiar with the installation method, the original data recovery, backup. Proficiency in the use of procedures, operations and editing. Software backup: WIN2003, WINXP, application, software installation program, database, etc., it is recommended to use the "one key to restore" software, easy to operate. Non full time personnel, please do not operate the software system.

5, box design for the display is also very important, on the one hand, it is the role of circuit protection, on the other hand is a safe role, as well as dust, waterproof effect. But more important is the ventilation cooling system design is good, with the extension of the boot time and the outside temperature, the thermal drift of components will increase, which leads to poor image quality.

extend of outdoor LED display screen using life of seven methods

1, outdoor LED display environment humidity, don't let any into the moisture properties of things your outdoor LED display screen. The humidity of the outdoor LED display power, will lead to parts of corrosion, resulting in permanent damage.

2, to avoid the problems that may be encountered, we can choose the passive protection and active protection, as far as possible the might of outdoor LED large screen screen caused harm to the items away from the screen, and clean the screen also as far as may be wiped gently, to minimize the possibility of injury.

3, outdoor LED display and the relationship between our users the most closely, do a good job cleaning and maintenance work is also very necessary. Long time exposure to outdoor environment, wind, sun, dust and other dirty, a period of time down, the screen is certainly a dust, which needs to be cleaned in a timely manner to prevent the impact of dust soil long time to watch the effect.

4, the requirements of power supply stability, and ground protection is good, in the harsh natural conditions, especially in strong lightning weather do not use.

5, the screen is prohibited in the water, iron powder and other easily conductive metal. Outdoor LED display as far as possible in the low dust environment, large dust will affect the display effect, while too much dust will cause damage to the circuit. If there are various reasons for the water, please immediately cut off and contact the maintenance staff, until the screen body display board dry before use.

6, we recommend of outdoor LED display screen daily rest time is more than 2 hours, in the rainy season of outdoor LED display screen for a week at least more than once. Generally at least once a month to open the screen, lit 2 hours or more.

7, play time not a long time in white, red, green, blue light screen, so as to avoid the current is too large, excessive power cord fever, LED lamp is damaged, which affects the display service life. Do not disassemble, splicing screen!
