What factors affect the quality of the LED display

LED display in our lives is very common, and that do not require us to buy LED display, LED display are used to broadcast advertising are the same, but for the need to purchase LED display friends, different LED screens have different performance has been mixed, then the LED display how to identify it? Then factor LED display quality? Henan LED display on the LED display in terms of distribution of the store, about four factors that determine the quality of the LED display. The first is the power LED display. LED display system power supply also affect an important part of quality. Power under different temperature conditions, the job stability, output voltage and load capacity will be different, because it is a logistical role, so it's support capabilities will directly affect the quality of the LED display . Power supply due to the different performance and stability, brand and size and therefore there is a big difference in the price difference, select power due to focus on performance and quality look. The second is the LED display of temperature conditions. Zhengzhou LED display on the temperature conditions can be quite picky, usually at room temperature of 25 degrees, an ideal working condition. But in fact, outdoor display in the application process is very complex ambient temperature, the temperature difference between summer, winter, since under different temperature conditions, LED, IC efficiency and performance will be inconsistent, causing the brightness will decay, and the display will have a cast change Flowers situation. The operating range of the IC is -40 ℃ -85 ℃, if the outside temperature is high, which results in the cabinet temperature is above 85 ℃, different IC will work instability, or drift arising from inter-channel current or tablets difference between too large resulting in the video. The third is housing LED display design. There are two aspects of the role of cabinet design, protective effect of one circuit, the second is security role, while dust and water, so the display box design is very important, but more important is the design of ventilation heat loop system, boot the extension of the test machine and the outside temperature, the thermal drift components increase will cause poor picture quality. The last point is the LED display production process. Ensure that the display quality of the production process is the focus, in the production process to maintain absolute static treatment, to ensure that the wafer is not damaged. Understanding the effects of the above factors on the four-point LED display quality, I believe when you need to buy LED display as long as the above four points as the reference, the strict understanding expedition LED display will be able to purchase to the satisfaction of the LED display .
