An outdoor P4 high refresh rate LED display module refers to a type of LED panel used for outdoor digital signage and advertising applications. The P4 designation indicates the pixel pitch, which is the distance between each pixel on the display module. A pixel pitch of P4 means that there are 4mm between each pixel.

The “high refresh rate” specification means that the LED display can refresh the images on the screen at a faster rate than standard LED displays. This is important for outdoor digital signage because it helps prevent flickering and provides a smoother image for viewers.

LED display modules like this are commonly used for outdoor advertising, sports venues, and other large-scale events. They are designed to be durable and weather-resistant, with features such as waterproofing and anti-corrosion technology.
