Abstract
A chain of bidirectional display driver integrated circuits (DICs). The chain has a beginning and an end, the chain includes a plurality of DICs, each of the plurality of DICs including: a direct data input, a relay data input, and a relay data output. Each of the plurality of DICs is configured to combine data received at the direct data input with a stream of bits received at the relay data input to form combined data, and to transmit the combined data through the relay data output.
