ABSTRACT:
A protection circuit described herein protects an LCD module from static electricity generated at a first positive power supply terminal in a process of manufacturing the LCD module. The protection circuit includes four diodes connected in series between a first node connected to the first positive power supply terminal and a second node receiving a reference potential, and a diode connected between the second and first nodes. When a first positive power supply voltage (10V) is applied to the first positive power supply terminal, the four diodes do not conduct. Therefore, a current consumption of the LCD module can accurately be measured.
