Abstract
A voltage test device used in liquid crystal display (LCD) panels, including test solder pads and test lines, is proposed. The test solder pads are connected to an LCD panel through the test lines. Each of the test lines includes a switch test line and a signal-inputting test line. The voltage test device further includes a first connector. The switch test line includes a first portion of the switch test line and a second portion of the switch test line. The first portion of the switch test line is connected to the second portion of the switch test line through the first connector. The first connector is used for preventing the electric current in excess of a predetermined threshold from flowing inside the LCD panel. Meanwhile, a voltage testing system used in LCD panels is proposed.
