LED- backlit LCD monitors have experienced spurt development this year. LED-backlit LCD monitors are gradually becoming more abundant in the market. Coupled with the continued decline in selling prices, more and more consumers have turned their purchase targets to LED backlight products. However, with the LED-backlit liquid crystal display fully rolled out in the market, many consumers often neglect the daily maintenance and maintenance of the LED-backlit liquid crystal display, so that long-term use not only affects the user's visual experience, but also the life of the display is greatly reduced. .
The increase in the use of LED liquid crystal displays, on the one hand, is due to the fact that major manufacturers have reduced the amount of workmanship materials in order to control production costs, resulting in the early aging of some products of some products; The reason is caused by the user's inappropriate use habits. Especially in the latter case, most users do not know how to properly use and maintain the LED liquid crystal display. Below, we will give you a brief introduction to the application and maintenance of LED-backlit LCD monitors.
Don't turn the brightness to the highest
Many users tend to adjust the brightness of the LED-backlit display when using the LCD, so that the color displayed at the beginning is very bright, but in fact, this usage habit is not desirable. In the store, many merchants will adjust the brightness of the display to the highest level in order to attract consumers' attention, and in the environment as large as the store, consumers will not feel uncomfortable. However, when the user uses it in his own home, the brightness of the display is adjusted to the highest level. On the one hand, it will have a certain impact on the user's eyes. For example, visual fatigue, after a short while, the eyes are very dry and affect. The user's vision; on the other hand, it affects the life of the LED.
The default brightness of the general display is 100. It must be manually turned down when using.
In fact, all of the current LED-backlit displays are equipped with a variety of application modes for users to choose, such as "Internet (è¹ è¹ network) mode", "game mode", etc. It is said that the brightness of the display is adjusted to adapt to different application environments. Therefore, when the user is using, the corresponding mode should be selected according to different application environments, instead of setting the brightness to the height state for a long time.
The display also has to work and rest
Since the basic display principle of the LED backlit display is the same as that of the conventional CCFL backlit display, the image is presented on the liquid crystal screen by the backlight. At the same time, the pixels of the liquid crystal display are made up of many liquid crystals. If the continuous use for a long time will cause the crystal to age or burn out, once the damage occurs, there will be bright spots and bad points that we say. It is permanent and irreparable.
The display also has to work and rest
In general, to extend the life of the monitor, do not leave the LCD monitor on for a long time (more than 72 hours). If it is not in use, turn off the monitor, or let the monitor display a white screen until it enters standby mode. .
Avoid hard objects bumping and scratching
For most LED-backlit displays, the most vulnerable part of them is the screen. The general screen hardness is below 3H (the hardness of the pencil lead). It is easy to be "injured" by other devices when not in use, and once the screen is affected Loss means that this LED display is basically scrapped.
Broken screen
To avoid possible problems, we can choose passive protection and active protection. Passive protection means that users in public places such as Internet cafes and bedrooms can choose to buy a display with tempered glass, which can make your display "invulnerable." Water and fire do not invade, but it will have an effect on the displayed color, and there will be reflections; and active protection is to be careful in the usual use, try to keep the damage to the screen from the screen, and clean the screen. Also wipe as gently as possible to minimize the possibility of injury.

Peel Mask PCB
Peel able masks are used in order to protect selected solder holes against plugging during mass soldering or to protect carbon elements and gold plated contacts during mass soldering. Peel able masks are screen printed.
Requirements
• The peelable mask must adhere sufficiently well to the PCB so that it does not peel off when handled correctly.
• It must be able to endure a two to three time soldering process without peeling off, but must remain detachable.
•After soldering of the PCB, the peelable mask must be able to be detached – preferably in one piece. In case of metallized holes, no mask
residue must be left in the drill holes or on the surface of the PCB. In the case of non-metallized drill holes, however a certain amount of residue
can remain.
• The peelable mask must be able to resist conventional solvents such as chlorinated and fluorinated hydrocarbons, isopropanol, conventional
fluxes and similar.
• Particular requirements: The roughness U of the edge of the mask can be 0,5 mm from the tip to the base (left figure
below).
