Abstract
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.
