Digit display is widely used in gas price sign, price sign, time/date/temperature clock, score board, exchange rate board, and all other displays which need display numbers, it is can take traditional printings or writings and provide a more efficient way to display the information, can change the numbers very quick.And the led technology it use can make the display shine with a hightness, even people from hundreds meters away can see the information. Also it is a energe-saving product.

The pcb board type digit display is similar to the normal led display, so it has the advantages of the normal led display, can control by software, high brightness, low energe cost. But it only has few necessary leds for the numbers, it can save much cost.

The disadvantage of PCB type digit display is waterproof, while we have 2 way to make it good for outdoor use:

1. waterproof cabinet, we make waterproof cabinet for digit display such as gas price display, assembly the pcb side and use waterproof connectors so it can be used outdoor.
2. use Parylene coating for the pcb, it can cover all the gap and the surface of all components and the pcb and the waterproof can be IP67 except the connectors, so if we use a good way to connect the power and signal, it will be excellent for outdoor use. The parylene coating is often used for gas price and the traffic display.
