 Today, outdoor LED displays dominate the advertising arena. There are different trade-offs depending on the needs of each project, such as pixel, resolution, price, playback content, display life, and pre- or post-repair options.

Of course, we must also consider the load-bearing capacity of the installation site, the brightness around the installation site, the viewing distance and viewing angle of the audience, the weather conditions of the installation site, whether it is rainproof, whether it is ventilation and other external conditions. So how do you purchase LED displays? Here are some suggestions for Powerful Big Colors.

1. The need to display content. The aspect ratio and the diploma are based on the actual content. The video screen is generally 4:3 or nearly 4:3, and the ideal ratio is 16:9.

2. Confirmation of visual distance and viewing angle. In order to ensure long-distance visibility in the case of strong light, ultra-high brightness LEDs must be used.

Industrial-grade integrated circuit chips with an operating temperature between -40 ° C and 80 ° C are selected to prevent the display from starting due to low temperature in winter. Install the ventilation equipment to cool down, so that the internal temperature of the screen is between -10 °C and 40 °C. An axial fan is installed on the back of the screen body to discharge heat when the temperature is too high.
