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).
