Actual LEDs are either on or off as required and simply have solid vibrant colours. Note: the pulsating effect shown is for demonstration purposes only.

Red 50% + Green 50% = Illuminated yellow blendįor full colour we have a third LED per pixel (Red, Green, Blue) Red 70% + Green 70% = Illuminated orange/amber blend Multicolour LED display (Red and Green LEDs) colours works like this: The picture below shows how an LED pixel glows.įor multicolour and full colour signs, we simply turn the LED lamps on for different amounts of time. This is how our scrolling message signs work.
In reality, it is a case of each pixel (LED lamp) being charged with electricity in an on-off fashion.įor example, if pixel A sits next to pixel B and is alternatively turned on-off it would appear as if the dot moves. China Red LED Moving Message Display Sign, Find details about China Programmable LED Moving Signs, Variable Message Signs from Red LED Moving Message Display Sign - POOSLED CO., LTD. When the sign is programmed and turned on, each pixel can illuminate independently and appear to 'glide' along the sign board panel. The resolution of the display is determined by how many pixels are in the matrix. Each LED lamp (pixel) is built up in a matrix, thus making up the length and height of the illuminated LED Display. Want to know how LED signs actually work?Ĭomplex integrated electronic circuits and software send pulsating electronic signals to each LED and when activated, they illuminate the individual LED (light emitting diode) lamp.
