Affect the display life of ten environmental factors – monitor, computer use – office supplies indus
When we buy when the display is very concerned about the display resolution, bandwidth, refresh rates, color reproduction capability, but often overlooked in the purchase after its maintenance, which monitors the reliability and service life shortened.
Purchase displays, we are very concerned about the resolution, bandwidth, refresh rates, color reproduction capability, but often overlooked in the purchase of future maintenance, which monitors the reliability and service life shortened. According to statistics, 50% of display failures due to poor environmental conditions caused by, 30% were due to improper operation or Management Caused by poor really poor quality or components as damage to the natural aging of the fault only 20%. Thus, environmental conditions and human factors are the main cause display failure. Therefore, the user must understand and master the display and maintenance of the general maintenance of common sense approach.
1. Temperature Adaptation temperature display, CRT in the 10 ~ 35 , liquid crystal display in the 0 ~ 40 (refer to the specific product instructions).
When the ambient temperature is too low, CRT Meng inside cover plate by cold deformation Ershi irregular blocks of color screen or deflection circuit of the deformation, resulting in blurred movement of the magnetic field or smearing. In addition, each Electronic Component has its work environment parameters. When the ambient temperature is too low, they may be the image jitter, distortion and other faults. CMV CMV-1502 LCD working environment temperature 5 ~ 35 , if the working environment temperature is below 5 , will be no show, failure is often mistaken for display.
Remind: when one monitor just returned from the outdoor temperature is below 0 and into the room, be sure not to immediately power up. Need to wait one hour or longer to display the same temperature and indoor temperature plus power to prevent the tubes as soon as power-induced burst.
Ambient temperature is too high, the display circuit itself is not easily dissipate heat generated out, could easily lead to poor heat dissipation, thermal breakdown occurs circuitry monitors damage caused.
2. Humidity Display normal humidity is 30% to 80%. Humidity is too large, easy to damage caused by high voltage discharge of FBT or other components. Meanwhile, the display circuit elements in the moist environment can easily damage or leakage. If condensation phenomenon, drops will cause a short circuit, causing greater damage. When humidity is too dry, prone to static electricity, causing electric shock phenomena, human injury or circuit damage.
3. Dust Monitor the internal pressure in the anode 20kV ~ 30kV, easily attract dust in the air. When the monitor placed in the dust or dusty environments, the high-pressure adsorption of the accumulation of dust on circuit boards, resulting in poor display circuit components heat damage, it may absorb moisture from the air of dust caused by the circuit component value changes or short circuit fault caused. At the same time, CRT screen will be lowered due to pressure of dust brightness, the user will unconsciously Adjust display brightness, resulting in premature aging CRT. For mills, cement factories, coal dust and other large units, should pay attention to computer peripherals such as dust.
For the effective prevention of dust hazards, ensure that the display in the use of relatively clean environment, should be to monitor the dust cover to purchase a dedicated, each time after use cast (careful not to cast off immediately, because the display After the shutdown will take some time to heat).
