LED display as emerging outdoor advertising carrier, compared with the ordinary advertising canvas, no matter the amount of information communication, attract the user's degree, the effect of the show are ordinary advertising incomparable. So we in the LED display screen of choose and buy when there are those factors affecting its quality? Power supply power in a 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. Cabinet design cabinet design is very important for LED display, on the one hand it is the 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. Temperature in theory LED display the best working state at room temperature 25 ℃ or so, due to the display screen are very picky about the environment temperature and outdoor LED display in the application environment temperature is relatively complex, the highest temperature in summer could above 60 ℃, the lowest temperature in winter may be in - Below 20 ℃. 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. 小编是专业的LED显示屏生产厂家,欢迎您前来咨询洽谈 0 上一条 led显示屏发展史 下一条 led广告屏价格范围_广告屏投资价格估算
