Summary:Methods and apparatus to reduce a coupling effect in a light emitting diode (LED) display are disclosed. An example LED display includes an array of LEDs, and a line controller to select a line of LEDs of the array of LEDs for illumination. The example LED display wall includes a column controller to control illumination of at least two of the LEDs of the line of LEDs. The column controller is to cause, when the first brightness value is less than a threshold, a first LED to be illuminated during a first time period and a second LED to be illuminated during a second time period. The second period is distinct from the first time period. The first LED is a different color than the second LED.
