Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the description of the present disclosure, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in fig. 3, and are not to be construed as limiting the present disclosure.

In the terminal, a transparent glass cover plate is mounted on the middle frame and positioned at the outermost side to protect the display screen positioned in the middle frame. As shown in fig. 1, the glass cover plate 11 is located in the middle frame 12, the middle frame 12 with such a structure has poor protection performance on the glass cover plate 11, and the glass cover plate 11 is easily broken when the display module falls off or other unexpected conditions. As shown in fig. 2, through setting up plastic frame 22, with the assembly of plastic 22 frame in center 23 bottom, glass apron 21 and display screen 24 are all installed on plastic frame 22, have improved the protection to glass apron 21, but the frame at this kind of terminal is great, and it is obvious to have the frame effect in the outward appearance, has reduced user experience. In order to further improve the protection effect to the glass apron, further propose the technical scheme of this disclosure.

Fig. 3 is a schematic partial structure diagram of a terminal according to an exemplary embodiment, and as shown in fig. 3, the terminal mainly includes:

a middle frame 110;

a transparent cover plate 130;

a protective frame 120 positioned in a gap between the middle frame 110 and the transparent cover plate 130; a concave platform 121 is arranged on one side of the protection frame 120 facing the central point of the protection frame 120;

a transparent cover plate overlies the recessed platform 121.

As shown in fig. 2 to 3, the frame size a of the terminal refers to: the width from the boundary between the black border region of the display screen 140 and the display region located within the black border region to the boundary line of the transparent cover 130. Generally, the smaller the bezel size a, the larger the end screen area ratio (ratio of the area of the display screen 140 to the area of the end front panel), the smaller the bezel feel, and the better the narrow bezel effect. On the contrary, the larger the frame size A is, the smaller the terminal screen occupation ratio is, the larger the frame feeling is, and the worse the narrow frame effect is.

In the embodiment of the present disclosure, the protection frame 120 is located at the edge 111 of the middle frame 110, and a concave stage 121 is formed toward the center point of the protection frame 120. The protective frame 120 is used for protecting the transparent cover plate 130, the concave table 121 has a supporting effect on the transparent cover plate 130, and the protective frame 120 is in contact with the transparent cover plate 130, so that the protective effect on the transparent cover plate 130 is improved, and the risk of breakage of the transparent cover plate 130 is reduced.

The protection frame 120 may be a frame body capable of generating deformation, and when the transparent cover plate 130 is subjected to impact force due to falling or other accidents, the external force can be buffered by the deformation of the protection frame 120, so as to reduce the risk of breaking the transparent cover plate 130. For example, the protective frame 120 is an elastic frame that can be elastically deformed. Further, the material of the protective frame 120 may be plastic or rubber. In addition, the protective frame 120 may also be made of a flexible material or a porous material, for example, the protective frame 120 is made of foam.

Further, the terminal further includes:

and the display screen 140 is positioned between the middle frame 110 and the transparent cover plate 130.

Generally, the middle frame 110 serves as a support for the display panel 140, and has a space 112 in which the protective frame 120, the display panel 140, and the transparent cover 130 are placed. By installing the protection frame 120 on the edge 111 of the middle frame 110, the occupation of the protection frame 120 on the space 112 in the middle frame 110 is reduced, the width C of the protection frame 120 can be made narrower, the installation space of the transparent cover plate 130 and the display screen 140 in the middle frame 110 is increased, the frame size a of the terminal is reduced, and the narrow frame effect is improved.

In a specific example, as shown in fig. 3 and 4, the width C of the protection frame 120 can be reduced to 0.15mm or even less than 0.15mm, and when the terminal structure shown in fig. 2 is adopted, the width of the plastic frame is 0.3-0.5 mm at the minimum. In order to reduce the occupation of the inner space 112 of the middle frame 110 by the protection frame 120, as shown in fig. 3 and 4, the side 123 of the concave platform 121 of the protection frame 120 close to the display screen 140 is flush with the side 113 of the middle frame 110 close to the display screen 140.

The material of the middle frame 110 includes, but is not limited to, one or a combination of two or more of plastic, metal, ceramic, etc.

The transparent cover 130 is made of a material with good light transmittance, so that the influence of the display screen 140 can be observed through the transparent cover 130. The transparent cover 130 is, for example, a glass cover or an acrylic plastic cover.

In a specific example, as shown in fig. 3 and 4, the transparent cover 130 covers the display screen 140, the display screen 140 may be directly fixed on the inner side of the transparent cover 130 without being fixed by the protective frame 120 or the middle frame 110, a safety gap D is provided between the edge of the display screen 140 and the middle frame 110, the safety gap D is a space reserved for expansion of the display screen 140 due to temperature increase, and the size of the safety gap D may be 0.2-0.5 mm, for example, 0.2mm, 0.3mm, 0.35mm, or 0.5 mm. Compared with the terminal shown in fig. 1 and 2, the safety gap is kept constant, the structure shown in fig. 3 and 4 is more favorable for installing the display screen 140 with the narrow black border area, and the display screen 140 with the narrow black border area can further reduce the size of the frame of the terminal.

In other alternative embodiments, the shape of the recessed portion 121 is adapted to the shape of the joint of the display screen 140 and the transparent cover 130.

For example: the section of the edge 111 of the middle frame 110 is downward step-shaped from the edge 111 to the center point of the middle frame 110, and the section of the protective frame 120 is downward step-shaped from the edge to the center point of the middle frame 110; or, the section of the edge 111 of the middle frame 110 is upward stepped from the edge 111 to the center point of the middle frame 110, and the section of the protection frame 120 is upward stepped from the edge to the center point of the middle frame 110.

Fig. 3 and 4 exemplarily show the middle frame 110 having a stepped section downward in a direction from the edge 111 to a center point of the middle frame 110, and the protection frame 120 having a stepped section upward in a direction from the edge 111 to a center point of the middle frame 110. In this case, as shown in fig. 3, the cross-sectional shape of the edge 111 of the middle frame 110 is a shape formed by two L-shaped frames which are combined end to end from top to bottom, and the cross-sectional shape of the protection frame 120 is a shape formed by L-shaped frames and I-shaped frames which are combined end to end from top to bottom. The cross section of the inner side of the protection frame 120 at the position where the concave stage 121 is provided is in an L shape, and the transparent cover plate 130 is fixed to the concave stage 121 by adhesive bonding.

The cross-sectional shape of the edge 111 of the middle frame 110 may be a downward step in the direction from the edge 111 to the center point of the middle frame 110, which is opposite to the inclination change tendency of fig. 3 and 4, and the cross-sectional shape of the inner side of the edge of the protection frame 120 may be a downward step in the direction from the edge to the center point of the middle frame 110, which is opposite to the inclination change tendency of fig. 3 and 4.

In other alternative embodiments, the top of the bezel 120 is exposed on the outer surface of the terminal in juxtaposition with the top of the bezel 110.

As shown in fig. 3, at the top of the terminal, the top of the bezel 120 is flush with the top of the middle bezel 110, and the bezel 120 may be exposed at the outer surface of the terminal. At this time, the protective frame 120 may have a decorative effect, for example, by giving different colors and/or patterns to the protective frame 120, a terminal having different appearance effects may be obtained.

Further, the width of the top of the bezel 120 is smaller than the width of the bezel 120 for carrying the transparent cover portion, thereby achieving a narrow bezel effect as much as possible.

In other alternative embodiments, the middle frame 110 is overlaid on top of the protective frame 120; the top portion 113 of the middle frame 110 is exposed to the outer surface of the terminal, and the top portion of the protective frame 120 is hidden inside the terminal.

As shown in fig. 4, the protective frame 120 is hidden in the middle frame 110 and cannot be exposed to the outside of the terminal, and at this time, only the middle frame 110 and the transparent cover 130 can be seen from the top appearance of the terminal.

In other alternative embodiments, the thickness of the top end of the adhesive layer 150 between the transparent cover plate 130 and the side 122 of the bezel 120 is less than the thickness of the bottom end of the adhesive layer 150 between the transparent cover plate 130 and the side 122 of the bezel 120.

As shown in fig. 3, the width of the adhesive layer 150 between the transparent cover plate 130 and the bezel 120 is small at the top and large at the bottom. In practical applications, the bottom of the side 122 of the bezel 120 may be extended outward, i.e. the side 122 is formed to be inclined outward, so that the area of the bottom surface of the recessed portion 121 is increased, and the amount of adhesive at the side 122 can be increased without increasing the gap between the top of the side 122 and the transparent cover 130.

In other alternative embodiments, the bottom surface of the transparent cover 130 is bonded to the upper surface of the recessed platform 121;

and/or the presence of a gas in the gas,

the side of the transparent cover plate 130 is adhered to the side of the protective frame 120.

The transparent cover 130 may be bonded to the upper surface of the recess 121 only through the bottom surface, or may be bonded to the side surface of the protective frame 120 only through the side surface. Alternatively, the bottom surface of the transparent cover 130 is adhered to the concave stage 121, and the side surface of the transparent cover 130 is adhered to the side surface of the protective frame 120.

When the protection frame 120 contacts with the side surface of the transparent cover plate 130, the protection frame further contacts with the bottom of the transparent cover plate 130 through the boss 121, so that the protection effect on the transparent cover plate 130 is further improved, and the risk of breaking the transparent cover plate 130 is reduced.

Without limitation, the adhesive layer 150 formed by the adhesive between the transparent cover plate 130 and the protective frame 120 has an L-shape.

In the embodiment of the present disclosure, the adhesive layer 150 formed by the adhesive is not only formed between the concave stage 121 and the bottom surface of the transparent cover plate 130, but also formed on the side surface 122 of the protective frame 120 above the concave stage 123, that is, the side surface of the transparent cover plate 130 is also fixed to the side surface of the protective frame 120 by the adhesive. Generally, as shown in fig. 2, when the conventional plastic frame and the glass cover plate are fixed, glue is only added between the bottom of the glass cover plate and the bottom of the plastic frame, and the width of the glue is large. In the embodiment of the present disclosure, the side surface of the transparent cover plate 130 is also bonded and fixed to the protection frame 120, so that the width E of the adhesive layer 150 between the bottom of the transparent cover plate 130 and the concave stage 121 is reduced, and generally, the width of the adhesive layer 150 for fixing the transparent cover plate 130 and the protection frame 120 is smaller, which is beneficial to further reducing the size of the terminal frame.

In a specific embodiment, as shown in fig. 3 and 4, the adhesive layer 150 formed by the adhesive between the transparent cover plate 130 and the protective frame 120 is shaped in an L-shape, and the width E of the adhesive layer 150 for fixing the transparent cover plate 130 may be not greater than 0.35mm, for example, the width E of the adhesive layer 150 is 0.3mm or 0.35 mm. If the glue is only added to the bottom surface of the glass cover plate as shown in FIG. 2, the width of the glue is at least 0.5-0.6 mm. Therefore, the adhesive layer 150 is formed between the side surface of the protection frame 120 and the side surface of the transparent cover plate 130, so that the width of the adhesive layer 150 is reduced, and the narrow-frame effect of the terminal is further improved.

In other alternative embodiments, the transparent cover 130 has a fitting gap with the side of the bezel 120.

In the embodiment of the present disclosure, when the transparent cover plate 130 and the protection frame 120 are assembled, only an assembly gap is formed between the transparent cover plate 130 and the protection frame 120, and the assembly gap is generally small, so that the risk that an adhesive located on the inner side leaks towards the outer surface of the terminal is reduced, the appearance is attractive, and the firmness of bonding the transparent cover plate 130 is effectively ensured.

As shown in fig. 3, when the top of the protective frame 120 is exposed on the outer surface of the terminal in parallel with the top of the middle frame 110, the transparent cover 130 has an assembly gap with the protective frame 120, and the distance between the transparent cover 130 and the middle frame 110 is the sum of the assembly gap B and the width C of the protective frame 120.

As shown in fig. 4, when the middle frame 110 is covered on the top of the protective frame 120; when the top of the middle frame 110 is exposed to the outer surface of the terminal and the top of the protection frame 120 is hidden inside the terminal, the distance between the transparent cover 130 and the protection frame 120 is equal to the width of the assembly gap B, and the distance between the transparent cover 130 and the middle frame 110 is also equal to the width of the assembly gap B.

The fitting clearance B is, without limitation, 0.05 to 0.1 mm.

As shown in fig. 3 and 4, a part of the side surface 122 of the protection frame 120 is inclined outward from the outer surface of the transparent cover plate 130 toward the concave stage 121, so that the thickness of the adhesive layer 150 can be increased without increasing the assembly gap, and the fixing effect of the transparent cover plate 130 can be ensured. Where the corresponding width of the adhesive layer 150 is F, and the overall width E of the adhesive layer 150 between the transparent cover plate 130 and the bezel 120 includes the width F of the adhesive layer 150.

In a specific example, as shown in fig. 3 and 4, the width of the top of the bezel 120 is approximately equal to the assembly gap B dimension, less than the width of the bezel 120 for carrying the transparent cover portion, so as to achieve a narrow bezel effect as much as possible.

In other alternative embodiments, the bezel 120 and the middle frame 110 are of a unitary structure.

Without limitation, the protection frame 120 may form a connected structure with the middle frame 110 by injection molding, and the connected structure ensures the bonding firmness of the protection frame 120 and the middle frame 110, and reduces the width required by the adhesive layer 150 and the like for connecting and fixing the separate protection frame 120 and the middle frame 110, which is beneficial to reducing the frame size of the terminal.

The conjoined structure of the protective frame 120 and the middle frame 110 does not need to assemble the protective frame 120 and the middle frame 110, thereby simplifying the manufacturing steps; and, the disadvantages caused by such assembly are reduced.

Further, the one-piece structure may be completed at the time of injection molding. For example, the middle frame 110 in the connected structure is made of a first injection molding material, such as: the first molding material is metal, and the bezel 120 is formed using a second molding material, such as: the second injection molding material is plastic, and the elasticity of the second injection molding material after cooling is larger than that of the first injection molding material after cooling.

In other alternative embodiments, the adhesive is formed on the side 122 of the protective frame 120 by a four-axis dispenser.

The adhesive between the protective frame 120 and the transparent cover 130 may be added to the side 122 of the protective frame 120 by side dispensing. Specifically, a four-axis dispenser may be used to add an adhesive to the side of the protection frame 120 and above the concave platform 121, when the transparent cover plate 130 is placed from top to bottom, the transparent cover plate 130 may press a portion of the adhesive onto the concave platform 121, the adhesive layer 150 may also be formed on the concave platform 121, and the bottom and the side of the transparent cover plate 130 are fixed to the protection frame 120 by the adhesive. Of course, during dispensing, the adhesive may be added to the side surface of the protective frame 120 and the concave portion 121 at the same time.

In one embodiment, the frame size a of the terminal in the embodiment of the present disclosure may be 1.2-1.3, and the minimum frame size of the terminal adopting the similar structure of fig. 1 and 2 is also 1.7-1.9 mm.

Alternatively, the display screen 140 may be a passive light-emitting display screen 140, or may be an active light-emitting display screen 140. In the case of the passive light-emitting Display screen 140, the passive light-emitting Display screen 140 refers to a Liquid Crystal Display (LCD) technology, a Liquid Crystal panel cannot emit light, and the terminal further needs to set a backlight assembly including a light source inside the middle frame 110, and the light source of the backlight assembly provides light to realize the light emission of the Display screen 140. In the case of the active light Emitting display panel 140, the active light Emitting mode refers to a light Emitting mode using an OLED (organic light-Emitting Diode) technology, that is, the display panel 140 is formed by a light Emitting Diode array, and a display unit of each OLED can be controlled to generate light of three different colors.

The embodiments of the present disclosure are further explained below with reference to the specific examples of the present disclosure shown in fig. 3 and 4, respectively, as compared to a similar structure shown in fig. 2.

Taking a similar structure shown in fig. 2 as a comparative example, taking a structure shown in fig. 3 as an example one of the present disclosure, the adhesive is also adhered to the side surface of the transparent cover plate 130 by using a side surface dispensing process, thereby reducing the dispensing width in the example one and narrowing the frame size of the transparent cover plate 130. Because the plastic frame in the comparative example is eliminated and the screen breaking problem is caused by falling, a circle of protective frame 120 with the width of 0.15mm is added on the inner side of the metal middle frame 110 through an injection molding process, in order to prevent the assembly gap B from being enlarged, and the side surface 122 of the protective frame 120 is required to be kept to be provided with an adhesive, the adhesive is partially added for 0.1mm below the side surface 122 of the protective frame 120 on the premise of not increasing the assembly gap B, and therefore the thickness of the adhesive layer 150 is increased. Further, a comparison and brief description of relevant dimensions of the comparative example and the first example are shown in table 1, wherein relevant dimension units in table 1 are all mm.

TABLE 1 comparative and example I comparative and brief description of relevant dimensions

Taking a similar structure shown in fig. 2 as a comparative example, taking a structure shown in fig. 4 as an example two of the present disclosure, the adhesive is adhered to the side surface of the transparent cover plate 130 by using a side surface dispensing process, so that the dispensing width in the example two is reduced from the side surface, and the frame size of the transparent cover plate 130 is narrowed. Because the plastic frame in the comparative example is eliminated and the screen breaking problem is caused by falling, a circle of protective frame 120 with the width of 0.15mm is added on the inner side of the metal middle frame 110 through an injection molding process. In order to prevent the assembly gap B from becoming large and maintain the side 122 of the bezel 120 to have an adhesive, the adhesive layer 150 is partially applied 0.1mm below the side 122 of the bezel 120 without increasing the assembly gap B. As a further improvement to the first example, in the second example, the protection frame 120 is not exposed outside the middle frame 110. Further, for a comparison and a brief description of the relevant dimensions of the comparative example and example two, see table 2, wherein the relevant dimension units in table 2 are all mm.
