Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

The terms "first", "second", and the like, used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.

Fig. 1 is a schematic partial cross-sectional view of a terminal according to an embodiment of the disclosure, in which, since no other structure (e.g., the front camera mounting hole 3 in fig. 2) is provided at a position of the screen auxiliary material 10 corresponding to the adhesive layer 4, a right edge of the screen auxiliary material 10 may be properly disposed toward the left side of the drawing direction to avoid exceeding a right edge of the screen 20.

Fig. 2 is a schematic partial cross-sectional view of a terminal according to an embodiment of the disclosure, in which another structure (such as the front camera mounting hole 3) is disposed at a position where the screen auxiliary material 10 corresponds to the adhesive layer 4. In order to ensure that the width of the bonding position of the screen auxiliary member 10 satisfies the requirements, the right side edge of the screen auxiliary member 10 is appropriately disposed toward the right side in the drawing direction.

As mentioned above, since there is a process deviation (i.e., a dimensional tolerance) in the fitting alignment between the screen assistant material 10 and the screen 20, the edge of the screen assistant material 10 may exceed the edge of the screen in the actual production process, as shown in fig. 3 and 4. Moreover, if the screen auxiliary material piece exceeds the edge of the screen, whether the specific value of the edge of the screen auxiliary material piece actually exceeding the edge of the screen meets the requirement or not is difficult to judge, especially under the condition that the screen auxiliary material piece is not transparent, the judgment is more difficult, whether the value of the edge of the screen auxiliary material piece exceeding the edge of the screen meets the requirement or not is difficult to detect in appearance or quality inspection, and even the condition of misjudgment can occur.

In view of this, the present disclosure provides a screen accessory 10, a screen module 1 including the screen accessory 10, and a terminal including the screen module 1.

As shown in fig. 1 and 2, a terminal provided by the embodiment of the present disclosure may include a middle frame 2 and a screen module 1, wherein an inner side (i.e., a back side) of a screen auxiliary member 10 is adhesively connected to the middle frame 2 through an adhesive layer 4, so as to securely connect the screen module 1 to the middle frame 2. Wherein the screen assistant member 10 may be adhesively connected to the top side, the left side, and the right side of the middle frame 2, respectively. Alternatively, the adhesive layer 4 may be a double-sided adhesive waterproof foam layer.

The terminal may be any terminal suitable for the screen module 1, such as a mobile phone and a tablet computer, which is not limited in this disclosure.

As shown in fig. 1 to 9, the screen module 1 provided by the embodiment of the present disclosure may include a CG cover 30, a screen 20, and a screen auxiliary member 10, wherein the screen auxiliary member 10, the screen 20, and the CG cover 30 are sequentially stacked, the screen auxiliary member 10 is located at an inner side of the screen 20, and the CG cover 30 is located at an outer side of the screen 20. Wherein, the screen auxiliary material member 10, the screen 20 and the CG cover plate 30 may be bonded in sequence. The screen assistant 10 may be foam, copper foil, or the like.

As shown in fig. 5 to 9, the screen auxiliary 10 provided in the embodiment of the present disclosure is provided with a first identifier 11, and the first identifier 11 is used for aligning with a second identifier 21 on the screen 20, so as to assist in determining whether a value of the edge of the screen auxiliary 10 exceeding the edge of the screen 20 is greater than a preset threshold.

Because the first identifier 11 is arranged on the screen auxiliary material piece 10, when the appearance or the quality is checked, based on the alignment condition of the first identifier 11 and the second identifier 21 on the screen 20, the operator can judge whether the value of the edge of the screen auxiliary material piece 10 exceeding the edge of the screen 20 is greater than the preset threshold value or not, and whether the value meets the requirement or not. Therefore, unqualified products can be detected, and the problems of fold, increase of foreign matters and the like caused by the fact that the edge of the screen auxiliary material part 10 exceeds the cover plate to be too large are avoided.

Based on the setting conditions of the first identifier 11 and the second identifier 21 on the screen 20, the operator can visually determine whether the value of the edge of the screen auxiliary material 10 exceeding the edge of the screen 20 is greater than the preset threshold, and can also determine whether the value of the edge of the screen auxiliary material 10 exceeding the edge of the screen 20 is greater than the preset threshold through a measuring means. For example, when the distance between the first mark 11 and the edge (e.g., the first edge 13) of the auxiliary material screen 20 is set to be equal to the preset threshold, the second edge 22 corresponding to the first edge 13 on the screen 20 may be set to be the second mark 21, and then, by directly observing whether the first mark 11 exceeds the second mark 21, it can be visually determined whether the value of the edge of the screen auxiliary material 10 exceeding the edge of the screen 20 is greater than the preset threshold. Alternatively, when the distance between the first mark 11 and the edge (e.g., the first edge 13) of the auxiliary material screen 20 is set to be smaller than a preset threshold, for example, zero, at this time, the first edge 13 is the first mark 11, the second edge 22 corresponding to the first edge 13 on the screen 20 may be set to be the second mark 21, and the screen auxiliary material 10 is designed to be a transparent member, in this case, whether the value of the edge of the screen auxiliary material 10 exceeding the edge of the screen 20 satisfies the preset threshold may be determined by measuring the distance between the first mark 11 and the second mark 21.

The present disclosure does not limit the specific value of the preset threshold, and may be any suitable value.

In the embodiment of the present disclosure, the first mark 11 may be in any suitable form, for example, the first mark 11 may be a mark point or a mark line.

Optionally, as shown in fig. 5, in an embodiment of the present disclosure, a viewing window 12 is disposed on the screen auxiliary 10, a first edge 121 of the viewing window 12, which is far away from the first edge 13 of the screen auxiliary 10, is a first mark 11, and a distance B between the first edge 13 and the first edge 121 is less than or equal to a threshold value. In this embodiment, the first edge 121 is an identification line. Since the distance B between the first edge 13 and the first edge 121 is less than or equal to the threshold, by observing whether the first edge 121 exceeds the corresponding edge (e.g., the second edge 22) of the screen 20, it can be determined whether the first edge 13 of the screen auxiliary 10 exceeds the second edge 22 of the screen 20 by too much. Taking the distance between the first edge 13 and the first edge 121 as an example, if the first edge 121 exceeds the second edge 22 of the screen 20, it is determined that the value exceeded by the first edge 13 of the screen auxiliary 10 is too large, and the requirement is not met, otherwise, the requirement is met. In addition, since the viewing window 12 is disposed on the screen auxiliary 10, when the screen auxiliary 10 is an opaque material layer, it can also be determined whether the value of the first edge 13 of the screen auxiliary 10 exceeding the second edge 22 of the screen 20 is greater than the preset threshold.

Alternatively, as shown in fig. 5, the viewing window 12 may extend to the first edge 13 to provide a notched configuration for the viewing nozzle. The design of the notch structure is convenient for processing the observation window 12 on one hand; on the other hand, a notch structure is formed, and the depth of the observation window 12 is the distance B between the first edge 13 and the first edge 121 of the screen auxiliary 10, so that the position relation between the edge of the screen auxiliary 10 and the edge of the screen 20 is more intuitive.

It will be appreciated that in other embodiments of the present disclosure, the viewing window 12 may be a window with side walls that are joined end to end.

It should be noted that, in the embodiment of the present disclosure, the first edge 13 of the screen auxiliary 10 is an edge where the screen auxiliary 10 is connected to the top side of the middle frame 2, or the first edge 13 is an edge where the screen auxiliary 10 is connected to the left side of the middle frame 2, or the first edge 13 is an edge where the screen auxiliary 10 is connected to the right side of the middle frame 2. Fig. 5 to 9 are only described by taking the first edge 13 as an example of an edge where the screen assistant material 10 is connected to the top side of the middle frame 2, but the first edge 13 is not limited to be the top side edge shown in fig. 5 to 9.

The distance from the first edge 13 to the first edge 121 is not limited in the embodiments of the present disclosure, and may be set as needed. For example, if the positional tolerance of the screen auxiliary member 10 to the first edge 13 and the second edge 22 of the screen 20 is ± 0.3mm, and the standard distance a required by design for the first edge 13 of the screen auxiliary member 10 to be beyond the second edge 22 of the screen 20 is 0.2mm, the screen auxiliary member 10 risks being beyond the edge of the screen 20 by 0.1 mm. In this case, as shown in fig. 5, two notches with a depth of 0.1mm may be designed on the screen auxiliary material 10 as the observation windows 12, and under the condition of normal fitting tolerance ± 0.3mm, the first edge 121 of the notch should coincide with the edge of the screen 20 in the limit condition, as shown in fig. 6. Therefore, the determination of whether the second edge 22 of the screen 20 is obscured by the notched first edge 121 can be used to visually determine whether the fit tolerance meets the design requirements.

It should be noted that the present disclosure does not limit the distance B between the first edge 13 and the first edge 121, that is, the specific value of the depth of the notch shown in fig. 5 is not limited. Optionally, in one embodiment of the present disclosure, the distance B between the first edge 13 and the first edge 121 may be 0.1mm-0.3 mm. In this range, the width of the bonding position of the screen auxiliary 10 is not affected by the opening being too large, and the bonding of the screen auxiliary 10 to the middle frame 2 is not affected. At the same time, the size can be visually observed by the operator, so that the judgment of the edge position of the screen auxiliary member 10 is made.

As shown in fig. 5 to 9, in the embodiment of the present disclosure, the plurality of observation windows 12 may be provided, the plurality of observation windows 12 are arranged at intervals along the extending direction of the first edge 13, and the arrangement of the plurality of observation windows 12 is beneficial to accurately determining the condition that each position of the first edge 13 of the screen auxiliary material piece 10 exceeds the edge of the screen 20, and can improve the accuracy of determining the condition that each position of the first edge 13 of the screen auxiliary material piece 10 exceeds the edge of the screen 20. Alternatively, the plurality of viewing windows 12 may each be the above-described notch structure.

In another alternative embodiment of the present disclosure, when the screen auxiliary member 10 is a transparent material member, the distance between the first mark 11 and the first edge 13 of the screen auxiliary member 10 may be set to be less than or equal to a threshold value. In the present embodiment, since the distance between the first edge 13 and the first mark 11 is less than or equal to the threshold, it can be determined whether the position of the screen auxiliary member 10 satisfies the requirement by observing whether the first mark 11 exceeds the second edge 22 of the screen 20 corresponding to the first edge 13. Moreover, since the second edge 22 is used as the second mark 21, the processing process of the screen 20 is simplified, the cost can be reduced, and the structure of the screen 20 can be simplified. In addition, since the screen auxiliary member 10 is a transparent material member, in this case, it is possible to judge whether the edge position of the screen auxiliary member 10 meets the requirement without viewing the window 12 on the screen auxiliary member 10, thereby simplifying the processing process of the screen auxiliary member 10, reducing the cost, and simplifying the structure of the screen auxiliary member 10.

Optionally, as shown in fig. 9, in another embodiment of the present disclosure, at least one third mark 14 may be further disposed on the screen auxiliary member 10, and the third mark 14 is located between the first mark 11 and the first edge 13 and is used for indicating a distance from a position of the third mark 14 to the first edge 13. By providing the third mark 14, it is advantageous to judge whether the edge of the screen assistant member 10 exceeds the specific value of the edge of the screen 20, and thus, it is advantageous to judge whether the width of the screen assistant member 10 satisfies the bonding width.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various combinations that are possible in the present disclosure are not described again.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
