The embodiment of the present application provides an electronic device 1000, and the electronic device 1000 may include, but is not limited to, a display screen assembly 100, a middle frame 200, and a rear cover 300. The display screen assembly 100 is attached to one side of the middle frame 200, and the rear cover 300 is attached to the other side of the middle frame 200 facing away from the display screen assembly 100. The display screen assembly 100, the middle frame 200 and the rear cover 300 enclose a space for accommodating a battery, a main board, a camera module and other structures. One side of the middle frame 200 corresponding to the display screen assembly 100 is provided with a step-shaped mounting groove 201, and the display screen assembly 100 is accommodated in the mounting groove 201 and connected with the middle frame 200. The middle frame 200 further has an inner edge surface 202, and the inner edge surface 202 is connected with the mounting groove 201.

Optionally, the electronic device 1000 may further include an adhesive 400, wherein the adhesive 400 is accommodated in the installation groove 201, and the adhesive 400 is located between the middle frame 200 and the display screen assembly 100, so as to fix the display screen assembly 100 and the middle frame 200.

Referring to fig. 4 and 5, fig. 4 is a schematic cross-sectional view of an electronic device in the related art, and fig. 5 is a partially enlarged view of a region C shown in fig. 4. In the related art, the display screen assembly 600 may include a light transmissive cover 601, a face plate 602, and a flexible circuit board 603. The light-transmitting cover plate 601 is substantially in a flat plate shape, and the panel 602 includes a first panel 6021 and a second panel 6022 arranged at intervals, and a bent panel 6023 connecting the first panel 6021 and the second panel 6022, wherein the first panel 6021 is attached to the light-transmitting cover plate 601, and the bent panel 6023 is substantially in a circular arc shape. The flexible circuit board 603 covers the outer surface of the bent panel 6023 and may be used to protect the bent panel 6023. The transparent cover plate 601 is accommodated in the mounting groove 201, and the surface of one side of the transparent cover plate 601, which is connected with the first panel 6021, abuts against the bottom surface of the mounting groove 201, so that the flexible circuit board 603 deviates from the surface of one side of the bent panel 6023 and is arranged in a gap with the inner edge surface 202.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Due to the existence of machining tolerance, assembly tolerance and deformation tolerance, specifically, the machining tolerance of the mounting groove 201 of the middle frame 200, the machining tolerance of the light-transmitting cover plate 601, the assembly tolerance of the light-transmitting cover plate 601 and the panel 602, the assembly tolerance of the light-transmitting cover plate 601 and the mounting groove 201 of the middle frame 200 and the deformation tolerance of the flexible circuit board 603 in the falling process of the display screen assembly 600, the limit distance d1 (or the minimum distance d 1) between the surface of the flexible circuit board 603 departing from the bending panel 6023 and the inner edge surface 202 is usually between 0.5mm and 0.6mm, so as to meet the assembly requirement of the display screen assembly 600 and the mounting groove 201. Specifically, if the limit distance d1 between the surface of the flexible circuit board 603 facing away from the bent panel 6023 and the inner edge surface 202 is too large, the screen occupation ratio of the electronic device 1000 is small; the limit distance d1 is too small to allow the flexible circuit board 603 to directly contact the inner rim surface 202, which affects the reliability of the display screen assembly 600.

Referring to fig. 3 and fig. 6 together, fig. 6 is a schematic cross-sectional view of a light-transmitting cover plate in the electronic device shown in fig. 3. The embodiment of the present application provides a display screen assembly 100, and the display screen assembly 100 may include a light-transmissive cover plate 10, a panel 20 and a flexible circuit board 30. The transparent cover plate 10 includes a substrate 11 and a side edge 12 extending from an edge of the substrate 11, wherein the substrate 11 and the side edge 12 enclose a receiving groove 101. The panel 20 includes a first panel 21 and a second panel 22 arranged at an interval, and a bending panel 23 connecting the first panel 21 and the second panel 22, wherein the first panel 21 is attached to the substrate 11. The flexible circuit board 30 covers the outer surface of the bending panel 23, and the flexible circuit board 30 is arranged with a gap from the side edge 12. It will be appreciated that the distance of the surface of flexible circuit board 30 facing away from bent panel 23 from the inner surface of side edge 12 is constant regardless of the tolerances between the assembly of display screen assembly 100 and bezel 200, which ensures that the surface of flexible circuit board 30 facing away from bent panel 23 does not come into direct contact with inner edge surface 202.

The light-transmitting cover 10 serves to protect the panel 20 and allows light emitted from the panel 20 to pass through the light-transmitting cover 10. The light-transmitting cover plate 10 includes a substrate 11 and a side edge 12 extending from an edge of the substrate 11, specifically, the substrate 11 of the light-transmitting cover plate 10 may include a first surface 111 and a second surface 112 disposed opposite to each other, and the side edge 12 is disposed at an edge of the first surface 111. The substrate 11 is substantially long, and the cross section of the transparent cover 10 along the width direction of the transparent cover 10 is substantially U-shaped. The substrate 11 and the side edge 12 form a receiving groove 101 for receiving the panel 20 and the flexible circuit board 30. Alternatively, the material of the light-transmitting cover plate 10 may be one of light-transmitting materials such as glass and plastic, and is not particularly limited herein.

The panel 20 can receive an electric signal and convert the received electric signal into an image signal. The panel 20 includes a first panel 21 and a second panel 22 arranged at an interval, and a bending panel 23 connecting the first panel 21 and the second panel 22, wherein the first panel 21 is attached to the second surface 112. In other words, the panel 20 includes a first panel 21, a bent panel 23 formed by extending from an edge of the first panel 21, and a second panel 22 formed by extending from an edge of the bent panel 23 away from the first panel 21, wherein the first panel 21 and the second panel 22 are disposed at a distance. Further, the first panel 21, the second panel 22 and the bent panel 23 may enclose a "U" shaped receiving cavity, so that the first panel 21 and the second panel 22 are disposed in a gap. The flexible circuit board 30 is located on the outer surface of the bending panel 23, that is, the flexible circuit board 30 is located on the surface of the bending panel 23 facing away from the receiving cavity.

Specifically, the shape of the first panel 21 corresponds to the substrate 11 and the area of the first panel 21 is smaller than that of the substrate 11, and the first panel 21 is a main display section of the display panel assembly 100. The second panel 22 is disposed parallel to and spaced apart from the first panel 21, and the second panel 22 corresponds to an edge position of the first panel 21. The bending panel 23 is substantially arc-shaped, so that the force applied to the bending panel 23 is uniform, and the panel 20 can be bent to form the first panel 21, the second panel 22 and the bending panel 23. The bending panel 23 and the second panel 22 serve as an auxiliary display interface for filling a gap between the first panel 21 and the middle frame 200, so that a black edge is prevented from appearing at the edge of the display screen assembly 100, and the screen occupation ratio of the display screen is improved.

The flexible circuit board 30 covers the outer surface of the bending panel 23, on one hand, the flexible circuit board can be used for protecting the bending panel 23, preventing the bending panel 23 from contacting with the middle frame 200, and improving the reliability of the bending panel 23, and on the other hand, one end of the flexible circuit board 30 is electrically connected with the panel 20, and the other end of the flexible circuit board is connected with the main board and used for communicating the main board with the panel 20. In this embodiment, the flexible circuit board 30 is made of a transparent material, so that the light emitted from the bending panel 23 can pass through the flexible circuit board 30, and the light emitting effect of the bending panel 23 is ensured.

It can be understood that, when the display panel assembly 100 is fixedly connected to the middle frame 200, the display panel assembly 100 is received in the mounting groove 201, a surface of the side edge 12 away from one end of the substrate 11 abuts against a bottom surface of the mounting groove 201, and a surface of the side edge 12 away from the receiving groove 101 abuts against an inner wall of the mounting groove 201, so as to ensure reliability of connection between the display panel assembly 100 and the middle frame 200. Unlike the related art display screen assembly 600, the mounting groove 201 corresponding to the display screen assembly 100 in the embodiment of the present application needs to be sunk, so that the mounting groove 201 can fix the side edge 12 of the display screen assembly 100.

The adhesive 400 is accommodated in the mounting groove 201 and located between the side edge 12 and the inner surface of the mounting groove 201, specifically, the adhesive 400 is located between the end surface of the side edge 12 facing away from the substrate 11 and the bottom surface of the mounting groove 201, and the surface of the side edge 12 facing away from the receiving groove 101 (i.e., the outer surface of the side edge 12) and the inner wall of the mounting groove 201, so that the side edge 12 can be fixedly connected with the middle frame 200.

Since the panel 20 is received in the receiving groove 101, the flexible circuit board 30 covers the outer surface of the bent panel 23, that is, the flexible circuit board 30 is also received in the receiving groove 101. Since the flexible circuit board 30 is accommodated in the accommodating groove 101 and is disposed in a gap with the inner surface of the side edge 12, the flexible circuit board 30 and the bending panel 23 are not affected by the processing tolerance of the middle frame 200, the processing tolerance of the transparent cover plate 10, or the assembling tolerance of the middle frame 200 and the transparent cover plate 10.

Optionally, the middle frame 200 further has an inner edge surface 202, a surface of the side edge 12 facing away from the receiving groove 101 may be flush with the inner edge surface 202, and a minimum distance d2 between a surface of the flexible circuit board 30 facing away from the bending panel 23 and the inner edge surface 202 is a minimum distance d2 between the surface of the flexible circuit board 30 facing away from the bending panel 23 and the inner edge surface 202. Since the distance from the surface of the flexible circuit board 30 facing away from the bent panel 23 to the inner surface of the rim 12 is constant, the minimum distance d2 between the surface of the flexible circuit board 30 facing away from the bent panel 23 and the inner edge surface 202 is constant and does not vary with the assembling tolerance of the light-transmitting cover plate 10 and the middle frame 200.

Alternatively, the minimum distance d2 between the flexible circuit board 30 and the side edge 12 may be 0.25mm, i.e. the minimum distance d2 between the surface of the flexible circuit board 30 facing away from the bending panel 23 and the inner rim surface 202 is 0.25 mm. Compared with the related art in which the minimum distance d1 between the surface of the flexible circuit board 603 facing away from the bending panel 6023 and the inner edge surface 202 is usually between 0.5mm and 0.6mm, the present embodiment reduces the distance between the bending panel 23 and the inner surface of the middle frame 200 by 0.25mm to 0.35mm, thereby improving the screen occupation ratio of the electronic device 1000, being more beneficial to the overall screen design of the electronic device 1000, and improving the competitiveness of the product.

Optionally, the display screen assembly 100 may further include an optical adhesive layer 40 and a polarizing layer 50, which are stacked, wherein the optical adhesive layer 40 is located between the substrate 11 and the polarizing layer 50, and the polarizing layer 50 is located between the optical adhesive layer 40 and the first panel 21. The optical adhesive layer 40 is used for bonding the substrate 11 and the polarized light layer 50, and the optical adhesive layer 40 has good light transmission performance and bonding performance, so that the polarized light layer 50 can be effectively bonded and fixed with the substrate 11, and the light transmission performance of the substrate 11 and the polarized light layer 50 is not affected. The polarized light layer 50 is used for eliminating dazzling reflected light and scattered light, so that messy light is changed into parallel light, the image of the panel is clearer, softer and clearer, and the user can watch the image conveniently.

Optionally, the display screen assembly 100 may further include a supporting layer 60, wherein the supporting layer 60 is located between the first panel 21 and the second panel 22 and is used for supporting the first panel 21 and the second panel 22, so as to ensure the reliability of the shapes of the first panel 21 and the second panel 22. Specifically, the supporting layer 60 may be made of one of elastic materials such as foam and silicone, and on one hand, the supporting layer 60 can support the first panel 21 and the second panel 22 and maintain the shapes of the first panel 21 and the second panel 22, and on the other hand, the supporting layer 60 can elastically contact with the first panel 21 and the second panel 22, so as to buffer and protect the first panel 21 and the second panel 22.

Further, the display screen assembly 100 may further include a first film layer 71 and a second film layer 72, wherein the first film layer 71 is located between the first panel 21 and the support layer 60, and on one hand, may be used to isolate the first panel 21 from the support layer 60, and on the other hand, may prevent light from the first panel 21 from passing through the support layer 60 and affecting the second panel 22 and the bending panel 23. Similarly, the second film layer 72 is located between the second panel 22 and the supporting layer 60, on one hand, to isolate the second panel 22 from the supporting layer 60, and on the other hand, to prevent the light of the second panel 22 from passing through the supporting layer 60 and affecting the first panel 21 and the bending panel 23.

Referring to fig. 7, fig. 7 is a schematic cross-sectional view of a variation of the electronic device shown in fig. 3. In this embodiment, the display screen assembly 100 may further include an auxiliary layer 80, and the auxiliary layer 80 is attached to a surface of the side edge 12 facing away from the receiving groove 101. When the display screen assembly 100 is accommodated in the mounting groove 201, the auxiliary layer 80 is sandwiched between the side edge 12 and the inner wall of the mounting groove 201 to control the assembly tolerance of the light-transmitting cover plate 10 and the mounting groove 201, improve the assembly precision of the display screen assembly 100 and the central controller, and improve the assembly strength of the side edge 12. Alternatively, the material of the auxiliary layer 80 may be metal, rubber, carbon fiber, etc., and is not limited in particular.

The display screen assembly 100 provided in the embodiment of the present application, through accommodating the panel 20 in the accommodating groove 101 surrounded by the substrate 11 and the side edge 12, the flexible circuit board 30 covers the outer surface of the bending panel 23, and the flexible circuit board 30 and the side edge 12 are arranged in a gap manner, so that the limit distance d2 between the flexible circuit board 30 and the middle frame is not affected by the processing tolerance of the middle frame 200, the processing tolerance of the light-transmitting cover plate 10, or the assembly tolerance between the middle frame 200 and the light-transmitting cover plate 10, which is beneficial to improving the screen occupation ratio of the electronic device 1000.
