The probe 13 is used for connecting corresponding pins on the display panel to be tested, then a test signal for simulating a real display picture externally is input into the display panel to be tested, the display panel to be tested can display different pictures according to the input test signal, and a worker judges the defects of the display panel by observing the display effect of different pictures on the display panel, so that the lighting test of the panel is completed.
According to the number and specification of pins on the display panel to be tested, the probes 13 with proper number and specification can be selected, and the plurality of probes 13 are correspondingly arranged on the mounting seat 11. A signal control board 40 may be provided at a lower end of the mounting base 11, the signal control board 40 may be electrically connected to the plurality of probes 13, and the signal control board 40 may transmit a corresponding test signal to the display panel to be tested through the plurality of probes 13.
In the lighting test process, the lighting clamping jaw 10 is driven by the moving component 30 to move to the position of the display panel to be tested, so that the pin area of the display panel to be tested is positioned between the pressing block 12 and the mounting seat 11, and the plurality of probes 13 on the mounting seat 11 face the pin area; then, the clamping assembly 20 drives the pressing block 12 and the mounting base 11 to move in opposite directions along the clamping direction, so that the pin area of the display panel to be tested is attached to the plurality of probes 13, and the other side of the display panel to be tested is pressed by the pressing block 12.
The clamping direction is a direction perpendicular to the surface of the display panel, for example, when the display panel is horizontally disposed, the clamping direction is a vertical direction.
