In a display panel, drivers for driving LEDs of pixels are distributed over a substrate, and transceivers relay pixel data from a timing controller to the drivers. The drivers are divided into groups. Respective drivers in a group receive corresponding pixel data addressed thereto solely from one corresponding transceiver. The corresponding transceiver and the respective drivers are daisy-chained to form one first linear daisy chain, where each pair of immediately-adjacent first drivers are connected. Plural first linear daisy chains are formed for all groups. The transceivers are daisy-chained to form a second linear daisy chain by connecting each pair of immediately-adjacent transceivers. The first and second linear daisy chains form a fishbone topology network to enable transmission of pixel data from the timing controller to the drivers while reducing a data-line footprint on the substrate that mounts the pixels, driver and transceivers in comparison to a conventional star-topology network.

A light-emitting diode (LED) includes a first electroluminescent (EL) component, a second EL component, a first segment electrode, a second segment electrode, and a first common electrode. The first segment electrode is electrically connected to the first EL component. The second segment electrode is electrically connected to the second EL component. The first common electrode has a first branch and a second branch which extend along a first direction and are arranged in a second direction different than the first direction. The first branch is located between the second branch and either of the first and second EL components, and the first and second branches are electrically connected to the first and second EL components, respectively.
