1. A display device comprising:
a plurality of light-emitting diode (LED) devices to implement an array of pixels to illuminate and present graphical information on the display device, wherein the array of pixels comprises a plurality of pixels, at least one particular pixel in the plurality of pixels comprises a plurality of sub-pixels, a first subset of LED devices in the plurality of LED devices implements the plurality of sub-pixels for the particular pixel, the first subset of LED devices comprises: a first LED device to implement a first color, a second LED device to also implement the first color, and a third LED device to implement a different second color;
scan line data circuitry to provide scan line data to the particular pixel and identify a color state to be applied through activation of a corresponding set of one or more of the plurality of sub-pixels at the particular pixel;
driver circuitry to drive the first subset of LED devices; and
controller circuitry to:
determine a first time window;
send a first signal to allow the driver circuitry to drive the first LED device to implement a first sub-pixel in the plurality of pixels for the particular pixel during the first time window when the first sub-pixel is activated based on the scan line data, wherein driving of the second LED device is blocked from implementing the first sub-pixel when the first sub-pixel is activated during the first time window based on the first signal;
determine a second time window; and
send a second signal to allow the driver circuitry to drive the second LED device to implement the first sub-pixel for the particular pixel instead of the first LED device during the second time window when the first sub-pixel is activated based on the scan line data, wherein driving of the first LED device is blocked from implementing the first sub-pixel when the first sub-pixel is activated during the second time window based on the second signal.
