In described examples, a system includes an output driver circuit (124) configured to operate a light emitting diode (LED) display (110) having multiple columns of LED devices. The output driver circuit (124) is configured to drive a given column output for the columns of LED devices in response to being activated based on data and a driver on signal supplied to the output driver circuit (124). A pre-discharge circuit (170) includes a separate discharge circuit connected to each of the column outputs. The pre-discharge circuit (170) is configured to discharge the given column output for a predetermined period of time before the output driver circuit (124) is activated. |
