3-3 Main function of Each Assembly

■ X-main board : The X-main board generate a drive signal by switching the FET in synchronization with logic
main board timing and supplies the X electrode of the panel with the drive signal through the
connector.
1) Maintain voltage waveforms (including ERC)
2) Generate X rising ramp signal
3) Maintain Ve bias between Scan intervals
■.Y-main board : The Y-main board generate a drive signal by switching the FET in synchronization with the logic
Main Board timing and sequentially supplies the Y electrode of the panel with the drive signal
through the scan driver IC on the Y-buffer board. This board connected to the panel's
Y terminal has the following main functions.
1) Maintain voltage waveforms (including ERC)
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
