COB display
|
Detailed Product Description
|
LCD displays each require one or more driver modules (s) to control
them. These ICs are either placed directly on a circuit board (as
COB or SMD) or as COG (Chip-On-Glass) directly on the LC glass. In
chip on board technology, the semiconductor chip (driver) is glued
directly onto a circuit board material and contacted there via bond
wires. For protection, the IC and the bonding wires are sealed with
a drop of potting compound using chip-on-board technology.
Chip-on-board displays are widespread and cheaper than LCD modules
with SMD components.
