After the rapid development of electronic digital products, many DIY geek players in China use development boards or open frame monitor. In the Internet era, open frame monitor 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 on the display screen through a specific transmission device to the human eye. For CRT, LCD and other types. Taking into account different application requirements and usage environments, industrial control displays are constantly being upgraded and changed. The most direct feeling for everyone is that the display accuracy and clarity are gradually improved, and the RGB color gamut has become wider and wider. The above is the dominant display of commercial displays. Features are widely used in daily applications. In industrial control displays, the factor of application improvement is not as simple as high definition and high pixel, it involves more realistic environment, such as power consumption, current, wide voltage, static electricity, dustproof, waterproof, scratch, Water vapor atomization, highlighting, contrast, viewing angle, etc., specific environment, specific requirements.
The high-brightness characteristics of open frame monitor and the characteristics of no water mist on the screen in outdoor environments with large temperature differences. Since most flat panel displays are used in an indoor environment, the brightness is about 250-300cd/m2, however, displays of this brightness level cannot meet the requirements when used in an industrial environment, because the ambient light will be stronger, Its brightness easily exceeds the brightness of the LCD backlight. In the usual medical, industrial and public telephone booths and other applications, the required brightness is at least 450cd/m2, or even higher. The high-brightness feature of the display means that the brightness and contrast of the display are increased to 2.5 times that of the ordinary display. It can solve the problem that the display screen is dim and cannot be seen clearly in a well-lit environment. At this time, the display screen must reach a certain brightness, so that people can watch the screen clearly. Similarly, in dimly lit scenes, the screen has to reduce the brightness to adapt to the surrounding light and avoid irritating the human eye.
If the usual environment of the display device is constant, then the brightness of the screen display does not change, such as in a dim factory or a factory where the lights are turned on regardless of day and night. But more often, in outdoor use scenarios, the application of the display needs to follow the time change and the light intensity to adjust itself to adapt to the surrounding light intensity, so as to better serve the human eye and not be affected by the light. Capture what's on the display.
The self-adjustment of the brightness of the industrial open frame monitor is the protection of the device itself. As an electronic device, the display can be burnt out due to long-term work. Therefore, from the perspective of maintenance, you need to turn off the display or reduce the brightness of the display 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, we can see the advantages of self-adjustment of display brightness.
Industrial control displays have 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 monitor 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. Displays often encounter some problems during use, which can be found in the process of maintenance and continuously improve the design, so that the application of industrial control displays can meet more applications, environments, and users.
