Summary: | An electronic device may include a display having an array of light-emitting diodes mounted to a driver die with driver circuitry for controlling the light-emitting diodes. The diodes may include contact pads. Contact pads for one of the diode terminals (e.g., the anodes or the cathodes) may be individually addressable, whereas the other diode terminals may share a common contact pad. The individually addressable contact pads and the common contact pad may be vertically stacked to improve thermal dissipation. The common contact pad may be interposed between the driver die and the individually addressable contact pads. Alternatively, the individually addressable contact pads may be interposed between the driver die and the common contact pad. Each LED array may have a dedicated driver die or one driver die may be shared between multiple LED arrays. A single LED array may include LEDs of multiple different colors. |
