full color LED display
are very picky about the environment temperature.
At room temperature 25 ℃ or so in theory, its working state is the most ideal.
But in fact, outdoor displays in the complexity of the application of environmental temperature, the highest temperature in summer could above 60 ℃, the lowest temperature in winter may be in -
Below 20 ℃.
LED, IC work efficiency and performance, brightness is inconsistent, the screen display also natural become spent as a whole.
Under the condition of different temperatures, red, green, blue three kinds of the brightness of the light attenuation and drop is different, at 25 ℃, the white balance is normal, but at 60 ℃, the three colors of the brightness of the leds are decreased, and the attenuation values are not consistent, so will produce the whole screen brightness decline and the phenomenon of partial color, the quality of the whole screen will drop.
Working temperature range is in - IC
Due to ambient temperature is too high the casing temperature, if the temperature over 85 ℃, IC, because temperature is too high, cause of the work is not stable, or the channel between current extraction and temperature drift or caused by too much difference between flowers screen.
Domestic display companies are working to a lot of improvements in the aspect of design, process, can effectively control the effects of the external environment temperature on the display screen eventually full color LED display as possible can perfect show in various complex conditions.
Enclosure the key factor for the design of the cabinet design is very important for display, on the one hand is its circuit protection, on the other hand is a safe, as well as dustproof and waterproof effect.
But more important is whether the ventilation cooling system of hot circuit design is good, with the increase of boot time and outside temperature, the components of the thermal drift also increases, resulting in image quality becomes poor.
Good ventilation and heat dissipation design is essential indicator of cabinet design.
The importance of power supply power in a full color LED display system are an important part of the quality of the impact.
Due to the power supply under the condition of different temperatures, the working stability, output voltage and load capacity will also be different, because it for the logistics function, therefore its ability to directly affect the quality of the screen.
Due to different performance and stability, brand and specifications of the power unit price also has the considerable differences.
Can't take a fancy to a low price and don't look at the performance and quality to choose.
The importance of the brand is a famous brand through long-term market cultivation to achieve social recognition.
Enterprise depending on the brand for life, never easy for short-term interests and hurt their own brand image.
And a few small companies or awareness is not high, in this respect have no scruples.
In order to short-term interests, sometimes at the expense of their own credibility, to hurt the behavior of the customer.
So, choose the big brand supply cgu sen photoelectric (shenzhen) co. , LTD. , is helpful for quality assurance.
GKGD saves time and increases productivity because it's one of the most complete sources of business and contact information.
