2-4. Touch controller structure
There are two kinds of PWBs. The one is Nicola PWB(AFE PWB) for driving or sensing the long length side and the other one is Astrea
PWB(DBE PWB) for driving or sensing the short length side and controlling the signal processing of touch recognition, coordinate
transmission and so on. The communication between these two PWBs are done by LVDS. They are connected by the harness.
