Abstract
An indication system is provided and includes evaluation, messaging, and display modules and a display. The evaluation module generates a message based on a parameter of a compressor or a drive. The messaging module: generates a message based on the parameter; generates a string of glyphs based on the message; selects a predetermined number of glyphs in the string of glyphs; generates column data for the selected glyphs; and generates packets including the column data. The display module generates output signals based on the packets. The display includes an array of LEDs, does not include a transistor, and illuminates the LEDs based on the output signals. The display module is configured to generate the output signals to illuminate one or more of the LEDS in a column-by-column format, such that power is only provided to one column of the array of LEDs at any moment in time.
