Description

Technical Field

[0001] This application relates to the field of displays, and more particularly to a display module and electronic device. Background Technology

[0002] Every year, a very high percentage of electronic products are scrapped due to water immersion or damage, prompting a pressing need for waterproof structural components. Currently, LSR (Liquid Silicone Injection Molding) is the mainstream waterproofing technology in the market. LSR technology achieves its waterproofing effect by co-molding liquid silicone with the phone's metal components. However, in existing LSR injection molding processes, poor adhesion between the screen and the injection mold leads to gaps, causing excess silicone and resulting in defective products.

[0023] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If the embodiments of this application contain terms relating to directional indications or positional relationships (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 relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0025] See Figures 1 to 4 In some embodiments, this application provides a display module 100, including a screen 1, which, together with a glue injection mold 2, forms a glue tank 21 for receiving glue. After the glue solidifies in the glue tank 21, it forms a glue block 22 fixed to the screen 1. The edge of the screen 1 is provided with a first bonding surface 11 for bonding with a second bonding surface 23 of the glue injection mold 2, increasing the bonding area between the screen 1 and the glue injection mold 2 to prevent gaps from forming between the screen 1 and the glue injection mold 2, thereby solving the problem of glue overflow at gaps and improving product yield, for example, preventing the glued screen from being scrapped due to glue overflow.

[0026] In some embodiments, the injection mold 2 includes a bottom wall 24 and a side wall 25 extending from the bottom wall 24, the bottom wall 24 and the side wall 25 forming a receiving cavity 251, and the display module 100 is placed in the receiving cavity 251 to form the glue groove 21 with the injection mold 2. The second bonding surface 23 is disposed on the side wall 25.

[0027] In some embodiments, the display module 100 is a quad-curved screen, meaning that the display module 100 is curved to a certain extent in all four directions: up, down, left, and right.

[0028] In some embodiments, the first contact surface 11 is inclined relative to the vertical direction.

[0029] In some embodiments, an edge of the screen 1 includes a third bonding surface 12 connected to the first bonding surface 11 for bonding to a fourth bonding surface 26 of the injection mold 2. A first seal is formed at the first bonding surface 11 and a second seal is formed at the third bonding surface 12, resulting in a better sealing effect and a better anti-overflow glue effect.

[0030] In some embodiments, an included angle between the first bonding surface 11 and the third bonding surface 12 is an obtuse angle, which not only facilitates placing the display module 100 into the receiving cavity 251 but also facilitates the bonding between the third bonding surface 12 and the fourth bonding surface 26.

[0032] In some embodiments, an edge of the screen 1 includes a first connecting surface 13 connected to the first bonding surface 11. The first connecting surface 13 is located below the first bonding surface 11. The glue groove 21 includes a gap groove 211 between the first connecting surface 13 and a second connecting surface 27 of the injection mold 2.

[0033] In some embodiments, the gap groove 211 may be in a shape with a smaller upper part and a larger lower part. The present application does not limit the shape of the gap groove 211.

[0034] In some embodiments, an included angle between the first connecting surface 13 and the second connecting surface 27 is an acute angle, and an included angle between the first connecting surface 13 and the first bonding surface 11 is an obtuse angle, such that the glue block 22 does not protrude from the screen 1. The present application does not limit the angle of the included angle between the first connecting surface 13 and the second connecting surface 27 and the angle of the included angle between the first connecting surface 13 and the first bonding surface 11.

[0035] In some embodiments, the screen 1 includes a display panel 14 and a glass cover plate 15 fixed together. The first bonding surface 11 is provided on the glass cover plate 15. An edge of the glass cover plate 15 extends beyond an end of the display panel 14. The glue block 22 is fixed to both the display panel 14 and the glass cover plate 15.
