Abstract
The present invention teaches a test device for a display panel which contains a signal transmission module, a first single reception module, and a second signal reception module. The signal transmission module transmits a test signal along a first conductive line in an active area and along a second conductive line in a fan-out area of the display panel simultaneously. The first and second signal reception modules detect the test signal on the first and second conductive line, respectively, so as to determine their conductivity. The present invention also teaches a test method for a display panel. By adding the second signal reception module in the fan-out area of the display panel, the present invention is able to effectively locate a faulty conductive line in the fan-out area where repair can be conducted. The yield of the display panel is as such enhanced.
