Common Problems in Iindustrial Display Applications & The Principle and Solution of Highlighting and Water Mist

In the Internet era, display applications can be seen everywhere. It belongs to the I/O device of the computer, that is, the input and output device. It is a display tool that reflects certain electronic files onto the display screen through a specific transmission device and then onto the human eye.

Considering different application requirements and use environment, the display is constantly upgrading changes, give you the most direct feeling is that the display accuracy and clarity gradually improved, RGB color gamut covering more and more broad, the above is the dominant characteristics of commercial display, in the daily application is very extensive. In the industrial display, the application of factors to improve is not high definition, high pixel so simple, it involves a more realistic environment, such as power consumption, current, wide voltage, static electricity, dustproof, waterproof, scraping, water vapor atomization, highlighting, contrast, visual Angle, specific environment, specific requirements.

Today we are going to introduce the highlighting characteristics of industrial displays, and how to avoid water mist in the outdoor environment of large temperature difference screen?

Since most flat panel displays are used in indoor environments, the brightness is about 250-300 CD /m2(Nit). However, this level of brightness is not suitable for use in industrial environments because the ambient lighting is much stronger, and the brightness can easily exceed the brightness of LCD backlights. In common medical, industrial and phone booth applications, the required brightness is at least 450cd/m2 or higher.

The highlight feature of the display is to increase the brightness and contrast of the display to 2.5 times that of ordinary display. It solves the problem that the display screen is dim and hard to see in well-lit environments. At this point, the display must be bright enough for people to see the screen clearly. Similarly, in dimly lit scenes, the screen brightness has to be lowered to match the ambient light and avoid irritating the human eye.

If the common environment of the display device is constant, then the brightness of the screen should not change, such as in a dim factory or a factory where the lights are on day and night. But more often, in the outdoor use of the scene, the application of the display needs to follow the time change, light intensity self-adjustment, to adapt to the surrounding light intensity, so as to better serve the human eye, not affected by the light capture content on the display.

Display brightness self-regulation, is the protection of the equipment itself.

As an electronic device, the display can burn out because of long-term work, so, from the maintenance level, when not used, the need to close the display or reduce the brightness of the display, otherwise for a long time, it will lead to internal burn or aging, this damage once it happens is permanent, irreparable. In addition, if the continuous display of a fixed content for a long time, will also lead to the overheating of some LCD pixels, and then internal burn out. From the above, you can see the advantages of self-adjusting display brightness.

The application scenarios of display are wide, and the use environment is complex and changeable, which requires a wider adaptability boundary of display. Not only can meet the wind and rain in different seasons, in its own power use, board and screen materials have a final life, and these external conditions will accelerate the aging speed of the display.

The water mist problem of outdoor environmental display is caused by the material, structure and environmental changes of the display itself. When the air flow meets the large temperature difference between morning and evening outdoors, coupled with the heat emitted by the display operation, water vapor will be generated inside and outside the screen within a certain period of time, and serious water flow will occur. The conventional solution is to do waterproof treatment outside the screen, the side of the LCD screen frame paste process, complete the closed management, so as to avoid internal water mist, affecting the operation of the machine.

Display in the use of the process often encounter some problems, we can find from the maintenance process, and constantly improve the design, so that the application of the display can meet more to meet the application, to meet the environment, to meet the user.
