Patent ID: 8552955

Claim:
A receiver for a source driver of an LCD panel comprising: a converter for converting two pairs of differential current signals that are embedded with data signals and control signals sent from a timing controller from being two pairs of differential current signals into two pairs of differential voltage signals; a comparing circuit coupled to the converter for generating reference voltage signals based on differences between the two pairs of differential voltage signals, the comparing circuit comprising: a first and a fourth node for receiving a first pair of the two pairs of differential voltage signals; a second and a third node for receiving a second pair of the two pairs of differential voltage signals; a plurality of resistors for generating a plurality of input signals based on the two pairs of differential voltage signals; a plurality of comparators coupled to corresponding resistors for receiving corresponding input signals and thereby generating the reference voltage signals; a plurality of first resistors coupled in series between the first and fourth nodes of the comparing circuit; and a plurality of second resistors coupled in series between the second and third nodes of the comparing circuit; wherein a node between two first resistors is coupled to a node between two second resistors; and a decoding circuit coupled to the comparing circuit for generating the embedded data signals and control signals based on the reference voltage signals.
