US 11,769,468 B2 · Spread-spectrum video transport integration with timing controller

Abstract

A timing controller of a display set is integrated with an encoder for transport of analog signals between a display controller and source drivers of the display panel. The timing controller and integrated encoder are within an integrated circuit and are part of a chipset. The integrated circuit is located immediately after the SoC of a display set or is integrated within the SoC. A video signal sent to the timing controller chip is unpacked into sample values which are permuted into vectors of samples, one vector per encoder. Each vector is converted to analog, encoded and the analog levels are sent to the source drivers which decode into analog samples. Or, each digital vector is encoded and then converted to analog. A line buffer uses a memory to present a row of pixel information to the encoders. A mobile telephone has an integrated TCON with SSVT transmitter.

Dependent claims

An apparatus that integrates a timing controller with a transmitter, said apparatus comprising:

at least one receiver arranged to receive a plurality of streams of digital video samples originating at a system-on-chip of a display set;
a distributor arranged to distribute said digital video samples of said streams into a plurality of input vectors according to a predetermined permutation;
a plurality of digital-to-analog converters (DACs) for each input vector that convert said digital video samples of said each input vector into analog video samples in parallel;
an encoder for each input vector arranged to encode said analog video samples of said each input vector into a series of analog values and to transmit said series of analog values to a display of said display set via an electromagnetic pathway corresponding to said each encoder;
and
a gate driver controller arranged to output gate driver control signals to gate drivers of said display of said display set.
