Common problems of industrial display applications and the principles and solutions of highlighting and water mist?

In industrial displays, the factor of application improvement is not as simple as improving the definition and high pixel, it involves a more realistic environment: such as power consumption, current, wide voltage, static electricity, dustproof, waterproof, scratch, water vapor fog Adjustment, highlighting, contrast, viewing angle, etc., specific environment, specific requirements.
The high-brightness characteristics of industrial displays, and how to prevent water fog from appearing on the screen in an outdoor environment with a large temperature difference?

The self-adjustment of the display brightness is the protection of the device itself.
As an electronic device, the monitor can burn out due to long-term work. Therefore, from the perspective of maintenance, you need to turn off the monitor or reduce the brightness of the monitor when not in use. Otherwise, it will cause internal burnout or aging after a long time. Once the damage occurs, it is permanent and irreversible. In addition, if a fixed content is displayed continuously for a long time, it will also cause some LCD pixels to overheat and burn out internally. From the above content, we can see the advantages of Hengstar display brightness self-adjustment.
The display has a wide range of application scenarios, and the use environment is complex and changeable, which requires a wider adaptability boundary of the display. Not only can it meet the wind, rain and sun in different seasons, but also when it is powered on itself, the board and screen materials have a final life, and these external conditions will speed up the aging speed of the display.
The water mist problem of the outdoor environmental display screen is caused by the change of the material, structure and environment of the display itself. When the air flow encounters a large temperature difference between morning and evening, plus the heat emitted by the display during operation, within a certain period of time, Water vapor will be generated inside and outside the screen, and water flow will occur in serious cases. The conventional response method is to do waterproof treatment on the outside of the screen, and use the LCD screen frame sticking process on the side to complete the closed management, which can avoid the occurrence of water mist inside and affect the operation of the whole machine.

Because the display is not a sealed port. There are many ventilation and heat dissipation holes on it, so the monitor must do the following three measures to achieve a waterproof structure:
The first layer, the surface of the LCD screen is waterproof, and an acrylic protective layer is made on the top of the display screen (or the touch screen and the LCD screen are fully bonded), and then the protective layer is glued firmly;
The second layer, the entire circuit board is covered with neutral waterproof glue, so that the LCD circuit board is immersed in the glue, of course, the glue needs to be neutral, not acid-alkaline, otherwise it will corrode the components;
After the third layer and the outer casing are assembled, apply waterproof glue on the joints of the outer casing, so that the entire LCD hardware part and the outer frame are connected, installed and fixed to be airtight.
The above three points are indispensable, but even this can ensure that nothing is lost, and there is no guarantee that a little water vapor will not get in. After all, water molecules can be said to be pervasive, and the mother of what we do is to minimize the appearance of water vapor.
