Onyx Data Drive Operation

ure 17 - Data Drive O

eration

The digital signal process is performed on the D-board. The analog RGB input signals

are converted to digital by IC9009 (not shown in this diagram). The 8-bit digital output

data enters IC9501 for processing.

The scan format of the digital video data is converted to progressive and mixed with the

OSD data. Adjustments such as white balance, contrast, color, and brightness are also

corrected here.

IC9302 contains the Plasma AI (Adaptive brightness Intensifier) circuit that analyzes the

video program level for the distribution of dark and bright components. The Plasma AI

circuit converts the 8 bit signal data to 10 bit signal data. The Sub-field Processor is

used to speed up the scanning process and control the number of Sustain periods. This

increases the brightness and improves the contrast ratio. The Sub-field Processor is

also used to create the four channels of data that drive the C1, C2, C3, and C4 data

output boards.

The D-board provides the scan, sustain, and data drive signals. The scan pulses are

output to the SC-board. The sustain pulses are output to the SS-board. The data drive

signals are output to the C1, C2, C3, and C4 boards. C1 board drives the upper right

portion of the panel. C2 board drives the upper left portion. C3 board drives the lower

left portion of the panel. C4 board drives the lower right portion of the panel.
