Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a display module and electronic equipment. Background Technology

[0002] In the backlight design of industrial displays, to save costs, the iron frame and the plastic frame are designed separately and assembled using snap-fit ​​positions. The reflector is attached to the reflector slot on the back of the plastic frame with adhesive on all four sides. The light guide plate is designed with snap-fit ​​positions to fasten with the plastic frame. The assembly process is as follows: first, fasten the light guide plate to the plastic frame → then assemble the reflector with double-sided adhesive on all four sides onto the reflector slot on the back of the plastic frame → then assemble the iron frame and the plastic frame together → assemble the light strip → finally assemble the optical film. However, because of the snap-fit ​​positions on the light guide plate, it needs to be placed from the back of the plastic frame during assembly. The plastic frame has a light guide plate snap-fit ​​slot, which makes the light guide plate unsuitable for automated equipment that assembles from the front, thus hindering automated assembly. Furthermore, the reflector needs to be attached with double-sided adhesive on all four sides and then assembled from the reflector slot on the back of the plastic frame, which also makes it unsuitable for automated equipment that assembles from the front, further hindering automated assembly.
