2) Generate Y-rising Falling Ramp
3) Maintain V scan bias
■
Logic main board : The logic main board generates and outputs the address drive output signal and the X ,Y
drive signal by processing the video signals. This Board buffers the address dirve output
signal and feeds it to the address drive IC (COF module)
(video signal- X Y drive signal generation , frame memory circuit / address data rearrangement)
■
.Logic buffer(E,F) : The logic buffer transmits data signal and control signal.
■
.Y-buffer board (Upper, Lower) : The Y-buffer board consisting of the upper and lower boards supplies the
Y-terminal with scan waveforms. The board comprises 8 scan driver IC’s
(ST microelectronics STV 7617 : 64 or 65 output pins) , but 4 ICs for the SD class
■
.AC Noise Filter : The AC Noise filter has function for removing noise(low Frequency) and blocking surge.
It effects Safety standards(EMC,EMI)
■
.TCP( Tape Carrier Package ) : The TCP applies Va pulse to the address electrode and constitutes address
discharge by the potential difference between the Va pulse and the pulse
applied to the Y electrode. The TCP comprise 4 data driver Ics(STV7610A
:96 pins output pins) 7 TCPs are required for signal scan
