Therefore, the situation that the collected display image of the display module 200 does not correspond to the pose of the flat cable 202 due to the error between the actual pose and the preset pose can be avoided, and the accuracy of the module flat cable calibration is improved.

Specifically, the actual attitude information of the flat cable 202 with respect to the display panel 201 at each preset position of the flat cable connector 4 can be acquired by the attitude acquisition device 6 located below the table 11.

Further, the step of "driving the flat cable connecting member 4 to move to a plurality of preset positions" specifically includes: the flat cable connector 4 is driven to translate to a plurality of preset positions along the X-axis, the Y-axis and the Z-axis relative to the display panel 201, so as to adjust the flat cable 202 to translate relative to the display panel 201, and thus, the flat cable 202 can be switched between a plurality of preset poses relative to the display panel 201.

Further, the step of "driving the flat cable connector 4 to move to a plurality of preset positions" further includes: the flat cable connecting member 4 is driven to rotate to a plurality of preset positions relative to the display panel 201, so that the flat cable 202 is adjusted to rotate relative to the display panel 201, and the flat cable 202 is switched between a plurality of preset poses relative to the display panel 201.

Compared with the prior art, the module flat cable calibration equipment 100 and the module flat cable calibration method provided by the invention have the beneficial effects that: the display module 200 is supported on the workbench 1, the driving mechanism 5 drives the flat cable connecting piece 4 to move to a plurality of preset positions, the flat cable 202 is driven to switch among a plurality of preset poses relative to the display panel 201, the display pictures of the display module 200 at each preset position of the flat cable connecting piece 4 are synchronously collected, the one-to-one correspondence between the preset positions of the flat cable connecting piece 4 and the preset poses of the flat cable 202 and the display pictures of the display module 200 is established, the automatic adjustment of the bending condition of the flat cable 202 is realized, the regulation and control precision is improved, the display pictures of the display module 200 after being adjusted are also collected, the image quality of each display picture is further analyzed, and the important guiding significance is achieved for optimizing the bending angle and radian of the flat cable 202 of the display module 200 relative to the display panel 201.
