Column drivers with embedded high-speed video interface timing controller

摘要

A system and method are disclosed for embedding a timing controller on column drivers which, among other advantages, reduces power consumption and size constraints. A standalone timing controller is eliminated by splitting a video input signal and delivering the signal to each of the column drivers. Timing controller functionality is embedded in each of the column drivers to allow the column drivers to process the received video signal. An auxiliary input used for communication between column drivers and an external system is received by a master column driver. The master column driver communicates with slave column drivers to enable point to point communication between each column driver and the external system.

1. A system for displaying a video signal, the system comprising:
a power divider:
having an input coupled to receive a video signal from an external system using a main link, and having a plurality of outputs to distribute the video signal to each of a plurality of column drivers, the video signal including video display information; and a column driver of the plurality of column drivers having an input coupled to receive the distributed video signal from one output of the plurality of outputs of the power divider, the column driver comprising:
a timing controller interface module coupled to receive the distributed video signal from the power divider and configured to generate one or more control signals to control the operation of at least on column driver of the plurality of column drivers based on the video display information, andan auxiliary module having an input coupled to receive an auxiliary signal from the external system and configured to determine if the column driver is a destination column driver of the plurality column drivers based on the auxiliary signal, and having an output coupled to send the auxiliary signal to an input of an additional column driver of the plurality of column drivers, using an auxiliary bus, responsive to a determination that the column driver is not the destination column driver.
