Property panel 102 is adsorbed on the second objective table 12, fixes flexible panel 102 with this；Finally, starting motor 151, drive shaft
(being blocked in figure by motor 151, reference can be made to Fig. 5 and Fig. 6) rotation drives the second objective table 12 to the first objective table 11 using shaft
Overturning, so that the bending in outer pin bonding area is realized, at this point, by the situation of lighting of observation flexible panel 102 can be obtained outer draw
The bending performance in foot bonding area.
Fig. 9 shows the schematic diagram for overturning the second objective table 12 in the direction of the arrow, and dotted box portion indicates overturning
Rear the second objective table 12, flexible panel 102 and outer pin bonding area (be located at the first objective table 11 and the second objective table 12 it
Between interstitial area), during the second objective table 12 is overturn to the first objective table 11, the outer pin bonding area of display module begins
Interstitial area of the final position between the first objective table 11 and the second objective table 12, and then ensure that the bending half in outer pin bonding area
Diameter.Moreover, the first fixed mechanism exposes the bayonet being electrically connected with external apparatus for lighting on flexible unit 101, and first carries
Object platform 11 be fixedly installed, will not be responded in 12 switching process of the second objective table on flexible unit 101 with external apparatus for lighting
Electrical connection, flexible panel 102 can be carried out in the bending process of flexible unit 101 lighting test, thus complete pair of flexible
The bend test of component 101 avoids and individually lights flexible panel 102 again after the bending for completing flexible unit 101, improves
The efficiency of bend test.
