It is not too late to know that the LED display quality assurance factor is originally these

The impact of complex temperatures on full-color LED displays Full-color LED displays are critical for ambient temperatures. Theoretically, it is at room temperature 25°C, and its working state is optimal. But in fact, outdoor full-color LED display in the application of the ambient temperature is quite complex, the summer maximum temperature may be above 60 °C, the minimum temperature in winter may be below -20 °C. LED, IC work efficiency and performance are inconsistent, the brightness is inconsistent, the overall display of the screen body also changed naturally. Under different temperature conditions, the red, green, and blue lamps have different brightness decays and decreases. At 25°C, the white balance is normal, but at 60°C, the brightness of the three colors of the LED is It has decreased, and its attenuation value is inconsistent. Therefore, the brightness of the entire screen will decrease and color cast will occur, and the quality of the entire screen will decrease.

What about IC? The IC's operating temperature range is -40°C to 85°C. Because the outside temperature is too high and the temperature in the cabinet rises, if the temperature in the cabinet exceeds 85°C, the IC will be unstable because of the high temperature, or the temperature difference may cause the current between the channels or the difference between the wafers to be too large. Causes Huaping. The domestic display manufacturers are making great efforts in the design, process, a lot of improvements, can effectively control the external environment temperature on the display of the final effect, as much as possible so that full-color LED display can be displayed in a variety of complex conditions .

The key factors in the design of the cabinet will increase, resulting in poor image quality. Good ventilation design is an indispensable indicator for the design of the cabinet. The Importance of Power The power supply is also an important part of the quality of a full-color LED display system. Because the power supply is under different temperature conditions, its working stability, output voltage value and load carrying capacity will also be different. Because it is responsible for logistical support, its guarantee ability will directly affect the quality of the screen.

Due to different performance and stability, there are considerable differences in the prices of power supply equipment of different brands and specifications. Can not just look at the low price without looking at its performance and quality to choose. The Importance of a Brand A well-known brand is recognized by the community after long-term market efforts. The company regards the brand as life and will not easily harm its own brand image for short-term benefits. Some small companies or companies with low visibility have no scruples in this regard. Sometimes, for the sake of short-term interests, he will not hesitate to sacrifice his own credibility and do harm to the customer. Therefore, choosing a large brand supplier is very helpful for quality assurance.
