How to avoid the damage caused by dust to LCD splicing screen?
Release time:2018-12-10  Read: 584

We all know that dust is harmful to the human body, but you certainly didn't expect dust to be the same for LCD splicing screens. Today, Zhongyu Vision is a small series that gives us a general idea of how much dust damages LCD splicing screens, just like smog. The human body is seriously damaged. The dust similar to smog is also the enemy of electronic goods. Liquid crystal splicing is an electronic commodity with extremely high technology content, and dust also has a great impact on it. The LCD splicing screen movement uses a lot of optical components, just the most damage to the optical components.


Dust brings 4 direct damage to the LCD splicing wall


Contrast drop


  The definition of contrast is the maximum brightness value that can be output by the large screen display unit divided by the darkest brightness value. When it is in a dark scene, the dust on the optical component will reflect the stray light, and the light that should not be projected from the lens will be projected. , add the brightness of the dark part. In the same bright part, some light will be blocked by dust, reducing the amount of reflection and transmission of light, and lowering the brightness value of the bright part. This contrast naturally decreases.


Color wheel speed drop


  The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor with a speed of about 7,200 rpm. If a lot of dust is attached around the color wheel, it will affect the rolling of the color wheel, and the rotation speed of the color wheel will be degraded or unstable, which will cause problems.


Screen brightness drops


  The brightness of the LCD splicing screen is outputted by the reflecting lens and the lens. If the dust is collected on the surface of the optical component, the reflectivity and transmittance decrease with time to form a decrease in brightness.


Causing the picture to appear vague


  When the dust is accumulated on the optical components inside the liquid crystal splicing screen to a certain extent, the light will be changed, so that the light collection cannot be collected on the same focus, so the picture on the screen becomes vague. clear. Usually we all think that dust only affects the appearance of the LCD screen, but I don't know how it affects the function of the LCD screen. In daily life, we must pay attention to dust prevention to extend the life of the product.


4 major maintenance methods for LCD splicing walls


Avoid strong impact


  Because the LCD splicing screen contains many precision glass components and electrical components, the LCD splicing screen is very delicate and the impact resistance is also poor. Once subjected to a strong impact, the LCD splicing screen and other related components are damaged. In addition, do not put pressure on the surface of the LCD screen, such as pointing a finger to a certain part of the screen.


Keep dry environment


  This is an important condition for the normal operation of the LCD splicing screen. The internal design of the LCD splicing screen is very precise. If the environment is wet, it will easily cause oxidative corrosion and short circuit, which will bring huge economic losses to the user. Therefore, try to keep the LCD splicing screen dry and use environment. If you find moisture on the screen surface, wipe it off with a soft cloth before turning on the power. If the moisture has entered the LCD splicing screen, the LCD splicing screen must be placed in a well ventilated or warm place to allow the water to evaporate. If the situation is more serious, ordinary users can ask professionals to help solve. Do not allow the LCD splicing screen to work when the moisture is not removed. Otherwise, the liquid crystal electrode will be corroded, which will cause permanent damage to the LCD splicing screen.


Correctly clean the LCD splicing screen


  The LCD splicing screen has been used for a long time, and it is easy to have some dust and dirt. It is inevitable to clean the LCD splicing screen. When cleaning, we should use the correct cleaning method: use a soft, non-fibre cotton wool, lens paper or soft cloth to absorb a little glass cleaner, gently wipe off the dust or dirt on the screen.


It is forbidden to use organic chemical solvents such as alcohol during cleaning, nor to use rough cloth or paper items, because such materials are prone to scratches and affect the display effect. Also be careful not to spray the cleaner directly onto the surface of the display screen, so that the cleaning agent can easily flow into the screen, causing short-circuit faults inside the LCD splicing screen and causing unnecessary losses.


Pay attention to the use time, avoid working for a long time


  Long-time overloading can easily cause some pixels of the LCD splicing screen to overheat, and if it exceeds the limit, it will cause permanent damage. The pixel of the LCD splicing screen is composed of a liquid crystal body. When the battery is continuously operated at full load for more than 95 hours, the aging process of the liquid crystal splicing screen is accelerated, and the burnt process is more serious. Therefore, users should pay attention to the use time when using the LCD splicing screen to avoid working for a long time. This not only prolongs the life of the LCD screen, delays the aging process, but also avoids hardware damage.
