Analog signal from the PC is changed to digital signal using the A/D converter integrated in scaler(MST6281). Scaler scale this digital singal to optimal signal fit to the panel and encode the LVDS signal.

This LVDS signla enter the panel to show the image through the LVDS Connector.

In Case of DVI singal, integrated TMDS Block is operating and processing.

MIcom control the all function of the monitor and OSD.

DC/DC Block make a suitable voltages from output 14V of I/P board which are used for function of all devices such as scaler, micom, memory, panel

IP board supplies voltages for main board and panel, at the same time, controls the lamp of panel back light.
