LED Displays
You’ve seen the moving LED signs as your driving down the highways in recent months. These moveable billboards allow more than one business to advertise on a particular space and remove the labor involved in the design and mounting of old-style paper billboard advertising.
A moving LED display is programmed to grab your attention and can be designed in various sizes for either indoor or outdoor use. The messages on these signs can be manipulated remotely through a software application. The way a moving LED sign works is that the light emitting diodes (LEDs) are turned on and off in a sequence that displays the message, this gives the appearance of movement in the sign.
The major component of every LED sign is the electronics board, which is made up of a grid of LEDs. There are some boards that are designed with single color diodes and others are made up of a combination of colors. More sophisticated LED board grids can contain bi- or tri-color LEDs. With a bi-colored board the color that is emitted is contingent on the direction that the light display travels, for example, if it travels to the right, the light could be displayed as red, but moving to the left the color could be displayed as blue. The speed at which the LEDs move back and forth can create even more colors. A tri-color LED is a misleading name as it is two LEDs encased on the same board that are controlled and wired separately but can be lit simultaneously to amp up the visible colors.
LED displays can be programmed to a simple flash or, through the use of RGB diodes (red, green, blue) can be programmed to emit the colors singly or in conjunction to form multiple color displays. Starburst patterns are also popular with moving LED sign displays. In the past, LED displays utilized “seven segment displays” but the technology has moved past this which only allowed for number and letter displays rather than moving pictures as can be found now.
Marketing executives and business owners are migrating toward moving LED displays as they allow for easier scheduling of messages and particular dates, locations and times of the day. As an example, a coffee shop may want to grab attention of the drivers during the morning commute while a grocery store may see more benefit from displaying its message on the after-work commute. LED technology continues to improve and expand its usage in both the consumer and industrial market.
