The reason why airport digital signage gets wide attention and fast development is that it has unsurpassable advantages itself. The advantages of indoor digital signs include high brightness, low working voltage, low power consumption, small size, long service life, impact resistance and stable performance. Advertising display screens have very bright development prospect and they are now developing towards higher brightness, higher weather fastness, higher luminous density, higher uniformity of luminance and higher reliability.

Key Factors of Cabinet Design for Indoor Digital Advertising Display:
Cabinet design is very important for an indoor digital advertising display, on one hand because of its circuit protection role, and on other hand, because of its safety role, and besides, it has the function of dust prevention and water proof. However, more importantly as for the design of the cabinet of electronic signs indoor, it is the design of heat return circuit used for ventilation and heat dissipation. Along with the extension of the turning-on time and the rising of the outdoor temperature, the heat drifting of the components and parts will also increase, which may influence the quality of the displayed images. For this reason, good ventilation and heat dissipation is the essential standard for the design of the cabinet of an indoor digital signage.

High Importance of Power Source of Indoor Led Display Signs:
Power source is another important factor influencing the indoor led display signs system. Under different temperature conditions, the working stability, output voltage values and carrying capacity of different power sources will be different. And since it is responsible for the logistical support, its support capacity will directly influence the quality of indoor screens.
