Modular system for controlling a liquid crystal display
First Claim
1. A modular electrical system for controlling a liquid crystal display (LCD) having a backlight and contained within a chassis, the system comprising:
- a backplane having first and second board edge connectors;
a video module having a board edge connector adapted to connect with the first board edge connector on the backplane, and a video input connection that is physically located on the video module but remotely from the video module board edge connector;
a power module having a board edge connector adapted to connect with the second board edge connector on the backplane, and an AC power input connection that is physically located on the power module but remotely from the power module board edge connector; and
a timing and control board (TCON) in electrical communication with the backplane and arranged to receive power through a power conduction line and electrical signals through a signal conduction line, the TCON configured to convert video signals output by the video module into driving signals for the LCD.

Abstract
A modular electrical system for controlling a liquid crystal display (LCD) contained within a chassis. The system may include a backplane in communication with a power module and video module through connectors on the back plane and respective connectors on the modules. The system may also include a timing and control board (TCON) that is in communication with the backplane via conduction lines that are provided to carry power, video signals, etc., to the TCON. Guides may be provided to ensure proper alignment of the power module and video module with the backplane. In some embodiments, the power module and video module may include input and output connectors that facilitate connection of multiple displays in a daisy chain fashion.
