After purchasing an outdoor advertising machine, some customers may have some problems, large and small, if the problem is not big, we can solve it by ourselves. The following editor will introduce a few of them to let everyone understand what they are. The reason, so that everyone can better solve it, let's take a look.
Outdoor advertising machine
The outdoor temperature is around zero, why does the screen appear black?
First of all, let's understand why the LCD screen will be black. Since the liquid crystal screen is composed of liquid and crystalline state, when the temperature exceeds 68 degree , the crystalline state will be transformed into a liquid state, causing display problems (ie, black screen). So why does the temperature go to a black screen when the temperature is around 0 degree ? Since the sun shines directly on the LCD screen at noon, and the liquid crystal molecules are very easy to absorb heat, the temperature of the LCD panel rises, which exceeds the maximum temperature and a black screen appears. According to this problem, this problem should be considered in equipment design. Although the ambient temperature is not too high, the fan still needs to be started and the speed can be reduced. The heat dissipation in front of the screen cannot be ignored.
2. With a filter, why is there still dust in the equipment?
The air-cooled advertising player is air-cooled, so there is airflow inside and outside the device. Use a double-layer filter to keep out small insects and large particles of dust. The filter needs to be cleaned during normal operation of the equipment for a period of time. The cleaning interval depends on the local environmental quality, such as 6 months, 8 months, or 1 year.
Although the filter filters dust, extremely fine particles can still enter the equipment. If you want to achieve no dust at all, you can only use the air-conditioning cooling scheme.
3. Is the beauty of the outdoor advertising machine important? Or is the stable quality important?
In some past projects, some customers asked us to change the internal heat dissipation, materials, etc. because of excessive demands for aesthetics. Improved aesthetics, lower stability and uncertainty, this method is somewhat worrying.
As an advertising player manufacturer for many years, outdoor advertising player is only one of our products. We will definitely improve the appearance under the premise of ensuring quality and stability. As a professional in the industry, you must be responsible for your customers' products, and you need to inform customers in time when there may be hidden dangers and correct them in time. The editor personally believes that no product should only focus on appearance, it must be a perfect appearance under the premise that quality is king.
