Bonding method of display module

The invention discloses a bonding method of a display module. The bonding method comprises the steps of: providing the display module and a bonding component, wherein the display module comprises a first closed contour, the bonding component comprises a second closed contour, a center point of the first closed contour corresponds to a center point of the second closed contour, the first closed contour comprises a first line, the second closed contour comprises a second line, the shape of the first line is completely consistent with that of the second line; prepositioning the bonding componentabove the display module; capturing the first closed contour and the second closed contour respectively, calculating the center points thereof respectively, and capturing the first line and the secondline respectively; performing alignment adjustment on planar positions and rotation azimuths of the display module and the bonding component; and bonding the bonding component on the display module.The capturing can realize p
