APPLICATION INFORMATION
Majority of Color LCD displays are made with Thin
Film Transistors (TFT) and as such are very vulnerable to
ESD damage. If an ESD stress hits the TFT display, it will
produce a black pixel/line.
ESD events can also create
Electromagnetic Interference (EMI). EMI radiated from an
ESD event can couple into a display through cables or I/O
ports and become a voltage or current spike. This spike can
then corrupt the operation of the sensitive TFT’s and affect
the display operation and quality.
Figure 6 shows a typical application of LX7207 is
suppressing ESD and EMI in color LCD displays. Exact
number of lines to be protected will depend on the
controller and LCD specifications such as number of bits
per pixel (bpp).
