When the RGB3 input is entered, the digital RGB signal input from the PL1 connector is of the serial data
and it is converted into the parallel data at the panel link receiver, IC7002. (Processing of RGB x 8 bits x 2
phases = 48 lines) IC7501 sends out an output signal of IC7002 to IC8502. This IC8502 is in charge of
screen size conversion for normal size, full size, digital zoom, etc. IC9000 sends out an output signal of
IC8502 to IC8003. This IC8003 is in charge of enhancer processing and NR processing. The processed
signal input is entered in IC9000 again. In this IC9000, γ processing, gradation processing, and white
balance processing are carried out for digital video signals. In addition, the synthesis of ON-screen signals
is also carried out there. In IC9003 and IC9004, 48-bit parallel signals are processed for conversion into
LVDS serial signals and the output is sent to the plasma display module ("AD" connector).
(6) Flow of dual screen display signals
"YU"
"PC"
"PL"
The chrominance (or RGB) signal input entered from the YU connector is converted into a digital signal at
the AD converter, IC6501. The RGB signal input entered from the PC connector is converted into a digital
signal at the AD converter, IC6701. In IC7501, the output signal from IC6501 is adjusted to obtain adequate
color depth and tone, and the output is sent to IC8003. In IC8003 and IC8502, screen size conversion is
carried out for the dual screen display. IC9000 sends out an output signal of IC8502 to IC8003. This IC8003
is in charge of enhancer processing and NR processing. The processed signal input is entered in IC9000
again. In this IC9000, processing of dual screen display is conducted through the synthesis of output sig-
nals from IC8003 and IC8502. In addition, γ processing, gradation processing, and white balance process-
ing are carried out for digital video signals. The synthesis of ON-screen signals is also carried out there. In
IC9003 and IC9004, 48-bit parallel signals are processed for conversion into LVDS serial signals and the
output is sent to the plasma display module ("AD" connector).
(7) Analog filter block
Before the digital conversion at the AD converter, the video signals pass through the low pass filter (LPF).
Signals of motion pictures for video, HDTV, etc., pass through an LPF of 8 MHz or 30 MHz. Each switching
IC (IC6005, IC6006, IC6007) is selected according to the type of signals and the output is entered in the AD
converter, IC6501. The PC signal is led through a 50MHz LPF, or otherwise, it is selected for each input
signal by each switching IC (IC6008, IC6009, IC6010, IC6011, IC6012, IC6013). The resultant input is
entered in the AD converter, IC6701. The signal intended to select a signal is output from the I/O extension
IC, IC6003. IC6003 is controlled by the I2C bus SCL2 and SDA2 from the microcomputer IC9501.
