[0020] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0022] See also Figures 1 to 5 In some embodiments, the present application provides a display assembly 100 comprising a display module 1 and a flexible circuit board 2. The flexible circuit board 2 is bonded to the display module 1 and forms a step 3 therebetween. During glue injection, the display assembly 100 is placed on a glue injection mold (not shown). The height difference caused by the step 3 creates a gap between the display assembly 100 and the glue injection mold. During glue injection, glue may flow from the gap to the back of the display module 1, causing glue overflow.

[0023] In some embodiments, a diaphragm fixing area (not shown) is provided at the step 3 for fixing to the diaphragm 4. A glue block 5 having a flat upper surface 51 can be fixed to the diaphragm 4 to eliminate the height difference caused by the step 3 and the gap caused by the height difference, thereby solving the problem of glue overflow caused by glue flowing out of the gap to the back of the display module 1. At the same time, the glue block 5 can be removed by removing the diaphragm 4, solving the problems caused by the glue block 5 being left behind, such as the problem of the glue block 5 occupying space and the problem of poor display function caused by the reaction with the stacking of the display module 1.

[0024] Although the solidified glue formed after the glue injection is bonded to the glue block 5 , the glue block 5 and the solidified glue can be separated when the film 4 is torn off due to the small contact area between the glue block 5 and the solidified glue.

[0025] The area of ​​the diaphragm 4 is larger than the area of ​​the bottom of the glue block 5 to ensure that the glue block 5 is completely located on the diaphragm 4 to prevent the glue block 5 from overflowing the diaphragm 4 and adhering to the display module 1 or the flexible circuit board 2, ensuring that the glue block 5 can be removed normally.

[0026] In some embodiments, the diaphragm 4 is a Mylar sheet, and the present application does not limit the material of the diaphragm 4.

[0030] In some embodiments, the film 4 includes a lifting portion 43, and the film 4 and the adhesive block 5 can be removed by lifting the lifting portion 43. The provision of the lifting portion 43 facilitates manual removal of the film 4.

[0031] When the glue injection is completed, the glue block 5 is no longer needed, and the lifting portion 43 can be pulled to tear off the film 4. Since the glue block 5 is on the film 4, the glue block 5 can be removed.

[0032] In some embodiments, the lifting portion 43 is fixed to the first fixing portion 41 .

[0033] In some embodiments, the lifting portion 43 is fixed to the second fixing portion 42 .

After the diaphragm 4 is fixed to the display module 1 and the flexible circuit board 2, the first fixing portion 41, the second fixing portion 42 and the third fixing portion 44 are Z-shaped to increase the stability of the diaphragm 4.

[0035] In some embodiments, the diaphragm fixing area is provided in plurality, and the plurality of diaphragm fixing areas are sequentially arranged along the length direction of the step 3. The diaphragm 4 can be provided at any desired location where a gap can be generated.

[0036] In some embodiments, one glue block 5 may be provided on one diaphragm 4 , or a plurality of glue blocks 5 may be provided on one diaphragm 4 .

[0037] In some embodiments, the display assembly 100 includes the glue block 5 , and the glue block 5 is fixed on the diaphragm 4 through a dam dispensing process.
