In the manufacturing process of the flexible display device, as shown in fig. 1, fig. 1 is a schematic structural diagram of a conventional flexible display panel after being bent normally, and a side edge of a flexible display panel 10 needs to be bent toward a supporting structure 11 and then bonded and fixed, but in the bending process, alignment deviation is easily generated between the flexible display panel 10 and the supporting structure 11, which causes a position of an initial pixel column in a display area AA to be shifted. In order to ensure that the position of the display area AA does not shift, all the rows of pixels need to be sequentially charged and checked one by one, so as to reconfirm the number of rows of the initial pixel rows of the display area AA.
As shown in fig. 1, it is assumed that the preset initial pixel column of the display area AA is the 7 th column of pixels of the entire flexible display panel, however, after the flexible display panel 10 and the supporting structure 11 have a misalignment, as shown in fig. 2, fig. 2 is a schematic structural diagram of a conventional flexible display panel that has a deviation after being bent, the 7 th column of pixels is no longer the initial column of pixels of the display area AA, and if the 7 th column of pixels has a deviation to the left side of the display area AA, at this time, the number x of columns of pixels in the initial column of the display area AA needs to be determined again, where x is a natural number greater than 1. However, since the offset between the flexible display panel 10 and the supporting structure 11 is unknown, the process of re-confirming the initial column number of pixels needs to sequentially charge all the pixels in the column for checking one by one, which reduces the production efficiency of the flexible display device.

the first pointer is over against a first column of pixels close to the first side edge in the extending direction of the columns of pixels;
after the first side edge of the flexible display panel is bent towards a supporting structure arranged on the non-display surface of the flexible display panel, the number of the display starting row pixels located in the display area and close to the first side edge is determined through a preset formula I according to the scale of the first pointer facing the row of pixels on the first scale.

Also, the first caliper structure 20 further includes a third pointer 203. The third pointer 203 is directly opposite to the sub-pixel of the 1 st column of the pixels near the first side C1 in the extending direction of the pixels of the columns.
After the first side C1 of the flexible display panel 2 is bent toward the supporting structure 3 disposed on the non-display surface of the flexible display panel 2, the number of columns of sub-pixels in the display start column located in the display area AA near the first side C1 is determined according to the scale of a column of sub-pixels on the first scale 201 directly opposite to the third pointer 203.

After the second side C2 of the flexible display panel 2 is bent toward the supporting structure 3 disposed on the non-display surface of the flexible display panel 2, the number of columns of sub-pixels in the display start column of pixels in the display area AA near the second side C2 is determined according to the scale of a column of sub-pixels on the second scale 211 directly opposite to the fourth pointer 213. The number of columns of sub-pixels corresponding to the scale of a column of sub-pixels on the second scale 211 directly opposite to the fourth pointer 213 is the number of columns of sub-pixels in the display start column of pixels in the display area AA near the second side C2.
Similarly, the third scale or the fourth scale includes not only the sub-scale lines corresponding to the sub-pixels, but also the sub-pixel column number identifiers corresponding to the sub-pixels, wherein the sub-pixel column number identifiers are numbers, letters or a combination thereof. Optionally, the sub-pixel column number is identified as the column number of the corresponding sub-pixel column, such as 1, 2, 3, etc. Of course, the present invention is not limited to this, and in other embodiments, the third scale or the fourth scale may include only the sub-scale lines, or may include other marks besides the sub-scale lines and the sub-pixel column number marks.
It should be noted that the first scale 201 in this embodiment is located between the first pointer 202 and the third pointer 203, but the present invention is not limited to this, and in other embodiments, the first scale 201 may be located on one side of the first pointer 202 and the third pointer 203, or on an extension line of the first pointer 202 or the third pointer 203. Similarly, the second scale 211 may be located only between the second pointer 212 and the fourth pointer 213, may be located on the side of the second pointer 212 and the fourth pointer 213, or may be located on an extension line of the second pointer 212 or the fourth pointer 213.
