Abstract
A visual indicator array has (M×N)/2 pairs of indicator devices arranged in a two-dimensional, linear array having M rows and N columns, where M is an integer greater than or equal to two, and N is an integer greater than or equal to one. The array also includes M/2 enable lines, each of which is connected to all of the indicator devices in two of the M rows to deliver enable signals to the indicator devices in the two rows. Likewise, each of N status lines is connected to all of the indicator devices in one of the N columns. Status information is carried by M×N status signals, and each of N selectors is connected to a corresponding one of the status lines. Each of the N selectors receives M of the status signals and selectively applies the M status signals to the corresponding status line one at a time.
