[0006] The display body has a main screen FPC and a backlight FPC. The main screen FPC has a plurality of first-type connection pads, and the backlight FPC has a plurality of second-type pads that are adapted to be soldered to the first-type pads. At least one second-type pad has a positioning mark.

[0007] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the plurality of second-type pads include a starting pad and an ending pad, and both the starting pad and the ending pad are provided with positioning marks.

[0008] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the positioning mark includes a first part and a second part, wherein the size and shape of the first part are adapted to the second type of solder pad, and the second part is perpendicular to the first part.

[0009] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the second part is vertically arranged at the head end of the first part.

[0010] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the width of the second part is not less than the width of the second type of solder pad, and the length is not less than 5.0mm.

[0011] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the color of the positioning mark is any one or a combination of black, red, yellow or blue.

[0012] As a further optimization of the display screen structure that facilitates automatic welding provided by this utility model, the positioning mark is printed on the second type of solder pad.

[0013] The display screen structure of this application, which is easy to automatically weld, has the following beneficial effects:

[0014] This application discloses a display screen structure that facilitates automatic welding. By setting positioning marks on the pads of the backlight FPC, the welding equipment can accurately complete the welding of the backlight FPC and the main screen FPC after COD identification, thereby improving the welding efficiency and accuracy.
