Most display manufacturers will only bin based on brightness or wavelength—forward voltage is largely ignored in the binning process since it can be controlled and adjusted on its own by a display’s driver chip.
Does binning have any downside?
The more specific one’s binning requirements, the smaller percentage of a given manufacturing run one is purchasing. This requires a provider to perform multiple runs, which adds to the cost. This is especially true when binning for both brightness and wavelength, as the more specific one’s bin requirements get, the more production runs one requires the manufacturer to perform. Binning to hit the Rec.709 colour space can increase costs by 20 to 30 per cent, while hitting cinema quality DCI-P3 (a common red, green, blue [RGB] colour space for digital movie projection from the American film industry) can increase costs by 50 per cent or more as bins to that standard can account for less than five per cent of a total production run. These increased costs are worth paying to deliver a display product that is consistent, high performing, and long lasting. After all, a chain is only as strong as its weakest link, and a display is only as good as its worst diode.
