X Board Additional Information
X Board Additional Information
There are three X boards, the Left, Center and the Right
(As viewed from the rear of the set).
The three X boards have very little circuitry. They are basically signal and
voltage routing boards.
• They route Va voltage to all of the Taped Carrier Packages (TCPs).
Va is introduced to the Left X board first, then the Left X sends
Va to the Center X and then the Center X sends Va to the Right X.
• They route the Logic (Color) signals from the Control board
to all of the Taped Carrier Packages (TCPs).
• The X boards have connectors to 23 TCPs, 8 on the left and right. The
Center X board has connections to 7 TCPs.
There are a total of 23 TCPs and each TCP has 2 buffers, so there are a total
of 46 buffers feeding the panel's 5760 vertical electrodes.
