Referring to fig. 1 to 3, in an embodiment, the mobile terminal 10 is a mobile phone, and the mobile terminal 10 includes a display screen module 100 and a rear case 200, where the display screen module 100 is fixedly connected to the rear case 200. Referring to fig. 3 and 4, in an embodiment, the display module 100 includes a cover plate 110 and a display 120, the cover plate 110 covers the display 120, the display 120 is at least partially accommodated in the rear case 200, and the cover plate 110 is fixedly connected to the rear case 200. In one embodiment, the display screen 120 includes a display area 122 and a non-display area 121(BM area, Black Matrix), and the display area 122 may be used to display information and may provide an interactive interface for a user. In one embodiment, the Display screen 120 is a Liquid Crystal Display (LCD) screen for displaying information, and the LCD screen may be a Thin Film Transistor (TFT) screen, an In-plane switching (IPS) screen, or a Liquid Crystal Display (SLCD) screen. In other embodiments, the mobile terminal 10 may be a tablet or the like.
In an embodiment, referring to fig. 4, the cover plate 110 includes a transparent substrate 111 and an ink layer 112, and the transparent substrate 111 is transparent. In one embodiment, the material of the transparent substrate 111 may be glass or sapphire, so that the transparent substrate 111 has high light transmittance. In one embodiment, the transparent substrate 111 has a substantially rectangular block shape. The transparent substrate 111 includes a plate main portion 1111 and an edge portion 1112, the edge portion 1112 is located at an edge of the plate main portion 1111, and the edge portion 1112 is curved toward a side of the display screen 120 to form an arc shape, so that the transparent substrate 111 as a whole encloses a cavity. It is understood that the edge portion 1112 is substantially an edge portion of the transparent substrate 111. When the transparent substrate 111 in the present application is manufactured, the flat straight plate can be processed through a hot bending forming process, so that the edge of the flat straight plate is bent into an arc shape, and the transparent substrate 111 in the present application is obtained. It should be understood that the transparent substrate 111 may have edge portions 1112 at two opposite sides thereof, that is, two opposite sides of the transparent substrate 111 have edge portions 1112, for example, the transparent substrate 111 arranged in a rectangular shape has edge portions 1112 at two long sides thereof, and two short sides thereof are also arranged in a plane; the transparent substrate 111 may be curved toward the display screen 120 at the peripheral edge thereof to form an arc shape, that is, the transparent substrate 111 may have an edge portion 1112 at the periphery thereof. Although the embodiments in the drawings are described by taking the edge portions 1112 at the two opposite sides of the transparent substrate 111 as an example, it should be understood that the drawings are only for illustrative purposes, and the specific side of the transparent substrate 111 having the edge portions 1112 is not limited.
The transparent substrate 111 has an inner surface 114 facing the display screen 120 and an outer surface 113 facing away from the display screen 112, and a connection face 115 connecting the outer surface 113 and the inner surface 114. The outer surface 113 has an outer arcuate surface 1131 on the plate body portion 1111 and an outer arcuate surface 1132 on the edge portion 1112, the inner surface 114 has an inner plate surface 1141 on the plate body portion 1111 and an inner arcuate surface 1142 on the edge portion 1112, and the connection surface 115 connects the outer arcuate surface 1132 and the inner arcuate surface 1142. The shape of the plate body portion 1111 may vary in different embodiments. In one embodiment, the plate body portion 1111 is planar, such as a 2.5D arc-shaped plate of the cover plate 110, i.e. the outer plate surface 1131 and the inner plate surface 1141 are planar; in another embodiment, the plate main body portion 1111 is curved in an arc shape, for example, if the cover plate 110 is a 3D arc plate, i.e. both the outer plate surface 1131 and the inner plate surface 1141 are arc surfaces, and the curvature of the plate main body portion 1111 is generally smaller than that of the edge portion 1112.
As shown in fig. 5, a first dashed dividing line 117 is provided at a connection point between the plate main body portion 1111 and the edge portion 1112, a portion of the transparent substrate 111 between the two first dashed dividing lines 117 is the plate main body portion 1111, and a portion of the transparent substrate 111 outward of the first dashed dividing line 117 is the edge portion 1112. It is understood that, when the cover plate 110 is installed on the display screen 120, the non-display area 121 of the display screen 120 may abut against the connection surface 115, that is, the edge portion 1112 is located above the display screen 120, and the non-display area 121 of the display screen 120 may also abut against the inner arc surface 1142, that is, the display screen 120 is at least partially accommodated in the cavity formed by the cover plate 110, which is not limited in detail.
The ink layer 112 is disposed on a side of the transparent substrate 111 facing the display screen 120. The ink layer 112 may be disposed on the inner surface 114, or may be disposed on both the inner surface 114 and the connection surface 115, which is not limited herein. The inner edge of the ink layer 112 defines a window area of the transparent substrate 111 for viewing information displayed during operation of the display screen 120 from a side of the outer surface 113 of the transparent substrate 111. At least a portion of the ink layer 112 is located on the edge portion 1112, and an orthographic projection of the ink layer 112 on the display screen 120 completely covers the non-display area 121 of the display screen 120. The orthographic projection of the ink layer 112 on the display screen 120 may extend beyond the edge of the non-display area 121 and cover a part of the display area 122, as long as it is ensured that the orthographic projection of the ink layer 112 on the display screen 120 completely covers the non-display area 121. It should be understood that the ink layer 112 may be located only on the edge portion 1112, or may be located on both the edge portion 1112 and the board main body portion 1111, and is not limited herein.
Specifically, the ink layer 112 is disposed on one side of the transparent substrate 111 facing the display screen 120, and an orthographic projection of the ink layer 112 on the display screen 120 completely covers the non-display area 121, so that the non-display area 121 is shielded by the ink layer 112. Thus, when the display screen 120 is lit, the non-display area 121 is blocked by the ink layer 112, and the non-display area 121 (i.e., the black edge) cannot be observed from the outside of the transparent substrate 111 (i.e., the side of the transparent substrate 111 opposite to the display screen 120), so that the display effect of the display screen 120 can be enhanced. An edge 1112 curved in an arc shape toward the display screen 120 is provided at an edge of the transparent substrate 111, and at least a part of the ink layer 112 is located inside the edge 1112. When the ink layer 112 on the edge portion 1112 is viewed from the outside of the transparent substrate 111 by the optical action of the arc-shaped light-transmitting plate, the part of the ink layer 112 exhibits a visual effect of narrowing in the direction in which the edge portion 1112 is bent. This is equivalent to narrowing the non-display area 121 of the display screen 120 in visual effect, which improves the aesthetic appearance of the mobile terminal 10.
In one embodiment, referring to fig. 5, an orthographic projection of the inner edge of the ink layer 112 on the display screen 120 coincides with an edge of the display area 122, that is, the window area is adapted to the display area 122 of the display screen 120, and it can be understood that the orthographic projection of the window area on the display screen 120 coincides with the display area 122. Therefore, the inner edge of the ink layer 112 is prevented from being projected on the display screen 120 and being located in the display area 122, and the situation that the ink layer 112 shields part of the display area 122 is caused, so that the viewing effect of the display screen 120 is influenced. It should be understood that minor deviations due to process errors are also to be understood as belonging to the overlapping cases referred to in this application. For example, when the ratio of the distance between the orthographic projection of the edge of the window area on the display screen 120 and the edge of the display area 122 to the width of the display area 120 is less than 1%, it can be considered that the orthographic projection of the window area on the display screen 120 coincides with the display area 122.
In an embodiment, the inner edge of the ink layer 112 does not exceed the connection point of the edge portion 1112 and the plate body portion 1111, that is, the ink layer 112 is only located on the edge portion 1112, and the ink layer 112 does not exceed the first dashed boundary line 117 in the direction toward the middle of the transparent substrate 111. By disposing the ink layer 112 on the edge portion 1112, when the ink layer 112 is viewed from the outside of the transparent substrate 111 according to the optical effect of the edge portion 1112, the entire ink layer 112 at this time exhibits a narrowing effect, which is equivalent to making the non-display area 121 of the display screen 120 relatively narrower in visual effect, thereby further improving the aesthetic property of the mobile terminal 100. It should be understood that the ink layer 112 is only located on the edge portion 1112, and that a small portion of the ink layer 112 may be located on the plate main body portion 1111 beyond the edge portion 1112 due to manufacturing errors, which is also the case when the ink layer 112 is only located on the edge portion 1112. For example, when the ratio of the distance of the inner edge of the ink layer 112 beyond the edge portion 1112 to the width of the plate main body portion 1111 is less than 1%, it can be considered that the ink layer 112 is only located on the edge portion 1112.
The orthographic projection of the inner edge and the outer edge of the ink layer 112 on the display screen 120 can be overlapped with the inner edge and the outer edge of the non-display area 121, so that the width of the ink layer 112 is the minimum while the orthographic projection of the ink layer 112 on the display screen 120 completely covers the non-display area 121, and a better visual effect is presented.
In one embodiment, referring to fig. 5, the connection of the edge portion 1112 and the board body portion 1111 is at the orthographic projection of the display screen 120 coinciding with the inner edge of the non-display area 121. The first dotted boundary line 117 is located not only at the connection of the edge portion 1112 and the board main body portion 1111 but also at the inner edge of the non-display area 121. Therefore, the orthographic projection part of the edge part 1112 on the display screen 120 is prevented from covering the display area 122, and when the display screen 120 is viewed from the outer side of the transparent substrate 111, the content in the covered part of the display area 122 is deformed to a certain extent, so that the viewing effect of the display area 122 is influenced. It is understood that the overlap condition is also the case when the orthographic projection of the edge portion 1112 on the display screen 120 slightly covers the display area 122 due to processing and manufacturing and assembling errors. For example, when the ratio of the distance between the orthographic projection of the edge portion 1112 on the display screen 120 and the inner edge of the non-display area 121 to the width of the display area 122 is less than 1%, it can be considered that the orthographic projection of the edge portion 1112 on the display screen 120 coincides with the inner edge of the non-display area 121.
As shown in fig. 6 and 7, the outer edge of the ink layer 112 coincides with the outer edge of the edge portion 1112. The outer edge of the edge portion 1112 is the connection between the connection surface 115 and the outer arc surface 1132. When the cover plate 110 is disposed over the display screen 120, the edge of the transparent substrate 111 generally extends beyond the edge of the display screen 120, i.e., the edge portion 1112 extends beyond the non-display area 121. By the outer edge of the ink layer 112 coinciding with the outer edge of the edge portion 1112, that is, by the ink layer 112 extending to the joint of the joint surface 115 and the outer arc surface 1132, the color of the ink layer 112 is uniformly presented in the region from the inner edge of the non-display area 121 to the outer edge of the transparent substrate 111. Therefore, the color difference between the areas from the outer edges of the non-display areas 121 and 122 to the outer edge of the transparent substrate 111 is effectively prevented from being inconsistent, and the appearance effect is further prevented from being influenced.
In one embodiment, the color of the ink layer 112 is the same as the color of the rear case 200. Therefore, the appearance color of the mobile terminal 100 can be ensured to be one, the cover plate 110 and the rear shell 200 can have an integrally formed visual effect, and the appearance is improved. For example, when the rear case 200 may be white, the ink layer 112 is also white, and the ink layer 112 extends to the outer edge of the edge portion 1112, so that the edge of the cover plate 110 and the rear case 200 are both white in appearance, and the color uniformity is exhibited, thereby improving the aesthetic property. It is understood that when the color difference between the ink layer 112 and the rear case 200 is within a certain range, if the color difference Δ E between the two is less than or equal to 1.5, the two colors can be regarded as the same.
In one embodiment, referring to fig. 4, the inner edge of the edge portion 1112 is stepped to form a receiving groove 116 for receiving the display screen 120. The inner edge of the edge portion 1112 is the connection point between the connection surface 115 and the intrados surface 1142. The accommodating groove 116 includes a first groove wall 1161 and a second groove wall 1162 connected to each other, the intrados 1142 is connected to the first groove wall 1161, and the connecting surface 115 is connected to the second groove wall 1162. When installed, at least a portion of the non-display area 121 is located in the receiving cavity 116. With the above arrangement, the display panel 120 and the transparent substrate 111 can be more stably mounted together.
Referring to fig. 4, 6 and 7, a buffer layer 118 is disposed between the ink layer 112 and the display screen 120. By arranging the buffer layer 118, when the transparent substrate 111 is impacted, the buffer layer 118 can absorb the impact, and the damage to the transparent substrate 111 and the display screen 120 caused by overlarge pressure between the transparent substrate 111 and the display screen 120 is avoided. The buffer layer 118 may be a super glue, which plays a role in fixing the transparent substrate 111 and the display screen 120 and also plays a role in buffering. Also, the orthographic projection of the buffer layer 118 on the display screen 120 may be located on the non-display area 121, and may further be located in an area where the orthographic projection of the intrados 1142 on the display screen 120 is located.
Referring to fig. 4 and 6, the ink layer 112 includes a first ink layer 1121 and a second ink layer 1122, and the first ink layer 1121 is positioned between the second ink layer 1122 and the transparent substrate 111; the orthographic projection of the first ink layer 1121 on the display screen 120 covers the non-display area 121 of the display screen 120, and the second ink layer 1122 is positioned on the first ink layer 1121. In an embodiment, the lightness of the second ink layer 1122 is less than the lightness of the first ink layer 1121. Lightness is a parameter used to characterize the shade of a color, e.g., lightness of white is 100% and lightness of black is 0%. When the cover plate 110 is placed on the display screen 120, the appearance of the first ink layer 1121 is observed by a user from the outside of the cover plate 110 (i.e., the outside of the transparent substrate 111). It is understood that the second ink layer 1122 covers the first ink layer 1121, and the second ink layer 1122 may cover a partial region of the first ink layer 1121; the area covered by the second ink layer 1122 can also be adapted to the size of the first ink layer 1121, so that the color consistency of the ink layer 112 can be relatively better ensured.
Specifically, in one embodiment, the first ink layer 1121 is a light ink and the second ink layer 1122 is a dark ink. The thickness of the first ink layer 1121 is greater than or equal to the thickness of the second ink layer 1122, and this arrangement can make the contrast of the lightness of the first ink layer 1121 and the lightness of the second ink layer 1122 more obvious. Further, in an embodiment, the first ink layer 1121 is a white ink layer having a lightness of 100%. The second ink layer 1122 is a black ink layer having a lightness of 0%. The second ink layer 1122 can also be a gray ink layer, which can provide better light blocking. In an embodiment where the first ink layer 1121 is a white ink layer and the second ink layer 1122 is a black ink layer, the thickness of the first ink layer 1121 is greater than or equal to the thickness of the second ink layer 1122, so that the white color of the first ink layer 1121 appears whiter, and the first ink layer 1121 is prevented from being darker due to the light transmission characteristic of the white ink.
It is understood that the number of first ink sublayers 1121 can be multiple layers. Specifically, in an embodiment, the first ink layer 1121 may include two or three white ink layers, and the three white ink layers are sequentially stacked on the same side of the transparent substrate 111. It is understood that the number of the first ink layers 1121 may be four or more. The first ink layer 1121 is obtained by means of multi-layer printing, and the lightness of the first ink layer 1121 is improved. For example, when the first ink layer 1121 is white ink, the white ink printed in a multi-layer printing manner can make the first ink layer 1121 look whiter than a single layer of white ink.
In an embodiment, as shown with reference to fig. 6 and 7, the curvature of the intrados 1142 of the edge portion 1112 is greater than the curvature of the extrados 1132 of the edge portion 1112. By making the curvature of the intrados 1142 greater than the curvature of the extrados 1132, that is, the degree of curvature of the intrados 1142 is greater than the degree of curvature of the extrados 1132, the ink layer 112 on the intrados 1142 becomes relatively narrower when viewed from the outside of the cover 110, and a relatively better visual effect is obtained. In one embodiment, the inner arc surface 1142 has a curvature greater than that of the outer arc surface 1132, so that the edge portion 1112 has a thick edge and a thin middle, and thus the visual effect is relatively better. And the ratio of the thickness of the thinnest part of the edge part 1112 to the thickness of the thickest part of the edge part 1112 is greater than or equal to 0.7, so that the part of the edge part 1112 which is too thin is prevented from being damaged easily due to the strength being greatly reduced.
