[0083] Figure 1 is a schematic diagram of a related display module. Figure 2 for Figure 1 The projection diagram of the near field communication structure in Figure 1 and Figure 2 As shown, the relevant display module includes a display panel 5, a composite film (Super Clean Foam, SCF for short) 7, a bending spacer 8, and a near field communication structure (NFC for short) 9, wherein the display panel 5 includes a display portion 13, a bending portion 14, and a binding portion 15, and the composite film 7 and the bending spacer 8 support the space between the display portion 13 and the binding portion 15. In the direction parallel to the display portion 13, the distance between the near field communication structure 9 and the binding portion 15 can be L, and the value of L is greater than or equal to 2.5 mm. For example, in some display modules, the distance between the near field communication structure 9 and the binding portion 15 is 2.5 mm, 3 mm or 5 mm. The binding portion 15 is projected onto the display portion 13 as projection A, and the near field communication structure 9 is projected onto the display portion 13 as projection B, wherein projection A and projection B are arranged at intervals, and the distance between the two is L. The inventors of this application have found that when the overall size of the display module is small, the surface area of ​​the near-field communication structure 9 in the display module is too small, which will lead to insufficient signal of the near-field communication structure 9 and poor short-range wireless communication performance of the display module.

[0084] Figure 3 is a schematic diagram of a display module of an exemplary embodiment of the present disclosure, Figure 4 for Figure 3 A projection diagram of a near field communication structure and a binding portion in the embodiment of the present disclosure provides a display module, such as Figure 3 and Figure 4As shown, the display module may include a display panel 5 and a near field communication structure 9, wherein the display panel 5 may include a display portion 13, a bending portion 14 and a binding portion 15 connected in sequence, the bending portion 14 may be folded to the backlight side of the display portion 13, and the near field communication structure 9 may be located on the backlight side of the display portion 13. The display portion 13, the near field communication structure 9 and the binding portion 15 may be arranged in sequence in a direction perpendicular to the display portion 13, and the orthographic projection B of the near field communication structure 9 on the display portion 13 and the orthographic projection A of the binding portion 15 on the display portion 13 at least partially overlap. Thus, the display module of this example extends the near field communication structure 9 to between the display portion 13 and the binding portion 15. Compared with the related display module in which the near field communication structure 9 does not extend between the display portion 13 and the binding portion 15, the display module of this example increases the area of ​​the near field communication structure 9, improves the signal amount of the near field communication structure 9, and ensures the short-range wireless communication performance of the display module.

When the bending portion 14 is installed, the bending portion 14 can be folded to the backlight side 23 of the display portion 13, so that the bending portion 14 is in a bent state and remains in a bent state. In the bent state, the bending portion 14 is surrounded by a nearly semicircular shape. The radius of the semicircle surrounded by the bending portion 14 is about 0.2mm to 0.5mm. In this example, the radius of the semicircle surrounded by the bending portion 14 is about 0.25mm, but it is not limited to this. For example, it can also be 0.2mm, 0.3mm or 0.35mm. The binding portion 15 is on the backlight side 23 of the display portion 13. The binding portion 15 is parallel to the display portion 13. The binding portion 15 has a chip mounting area (Chip On Panel, referred to as COP) area and a driver integrated circuit area (Driver Integrated Circuit, referred to as D-IC). A first gap 24 is formed between the binding portion 15 and the display portion 13 , and a component is required to support and fill the first gap 24 to support the space between the binding portion 15 and the display portion 13 .

The chip 11 is located on the surface of the binding portion 15 away from the display portion 13, and is bound to the chip mounting area of ​​the binding portion 15 to form an electrical connection. In addition, the orthographic projection of the chip 11 on the display portion 13 is located within the orthographic projection of the near field communication structure 9 on the display portion 13.

When the near-field communication structure 9 is assembled with the display panel 5, the double-sided adhesive 16 and the near-field communication structure 9 are fed as one, which can reduce the preparation steps and effectively optimize the production line process without increasing the manual work for the corresponding double-sided adhesive 16 attachment. In an exemplary embodiment, the thickness of the double-sided adhesive tape 16 can be set to 0.02 mm to 0.05 mm.

The orthographic projection of the double-sided tape 16 on the display portion 13 may be located within the third projection C, and the orthographic projection of the chip 11 on the display portion 13 may also be located within the third projection C. In an exemplary embodiment, the overlapping projection area of ​​the second projection A and the first projection B is the area of ​​the third projection C, and the area of ​​the third projection C may be greater than two-thirds of the area of ​​the second projection A. In this example, the area of ​​the third projection C is approximately four-fifths of the projection area of ​​the second projection A, but is not limited thereto. For example, the area of ​​the third projection C is approximately seven-ninths of the area of ​​the second projection A, and for another example, the area of ​​the third projection C is approximately three-quarters of the area of ​​the second projection A. In an exemplary embodiment, the projection area of ​​the positive projection of the near field communication structure 9 on the display portion 13 is the area of ​​the first projection B, and the area of ​​the first projection B is not less than two-thirds of the area of ​​the display portion 13.

[0115] In some exemplary embodiments, Figure 3 , Fig. 22 , Fig.23 and Fig.24As shown, the material of the conductive member 34 may be conductive foam or conductive double-sided tape, which is conductive and flexible. The conductive member 34 in this example is made of conductive foam, but is not limited thereto. For example, the material of the conductive member 34 may be other flexible and conductive materials other than conductive foam and conductive double-sided tape. The cross-section of the conductive member 34 on a plane parallel to the display portion 13 may be rectangular, so that the shape of the conductive member 34 matches the hole shape of the second through hole 36 and the first through hole 35, but is not limited thereto. For example, the cross-section of the conductive member 34 on a plane parallel to the display portion 13 may be circular, trapezoidal, rhombus, triangular or irregular in shape, and the second through hole 36 and the first through hole 35 are both configured as corresponding circular holes, trapezoidal holes, rhombus holes, triangular holes or irregular holes corresponding to the conductive member 34.

The conductive member 34 passes through the first through hole 35, and the outer wall of the conductive member 34 and the inner wall of the first through hole 35 are spaced apart, that is, there is a second gap 38 between the outer wall of the conductive member 34 and the inner wall of the first through hole 35.

The third gap 39 may be a gap surrounding the conductive member 34, so that the conductive member 34 does not contact the inner wall of the second through hole 36. The minimum distance between the outer wall of the conductive member 34 and the inner wall of the second through hole 36 is about 0.3 mm to 0.7 mm. In this example, the minimum distance between the outer wall of the conductive member 34 and the inner wall of the second through hole 36 may be 0.5 mm, but it is not limited thereto. For example, the minimum distance between the outer wall of the conductive member 34 and the inner wall of the second through hole 36 may be 0.4 mm, and for another example, the minimum distance between the outer wall of the conductive member 34 and the inner wall of the second through hole 36 may be 0.6 mm.

The display device provided in the embodiment of the present disclosure can be applied to electronic devices, and can be a mobile phone, a tablet computer, a television, a display, a laptop computer, a digital photo frame, a navigator, a car display, or any product or component with a display function such as a wearable device, such as a smart watch, a smart bracelet, smart glasses, smart headphones, smart clothing, a head-mounted display, etc. In this example, the display device is a mobile phone, and by increasing the space occupied by the near-field communication structure 9, the signal amount of the near-field communication structure 9 can be guaranteed while simplifying the structure.

[0120] In combination with the above embodiments, the display module increases the space occupied by the near-field communication structure 9 to ensure the signal volume of the near-field communication structure 9, so that the performance of the display device at the 12 o'clock and 6 o'clock directions is close. The display module reduces the thickness of the composite film, and replaces the curved gasket with double-sided tape 16, and then extends the near-field communication structure 9 to increase the area of ​​the near-field communication structure 9, thereby improving the performance of the near-field communication structure 9. The display module can achieve the overall maximum stacking thickness unchanged, but the signal of the near-field communication structure 9 will be greatly improved, and the cancellation of the curved gasket can save material and labor costs. The double-sided tape 16 and the near-field communication structure 9 signal are fed as one, which effectively optimizes the production line process without increasing the labor corresponding to the double-sided tape 16 attachment. The display module introduces electrostatic field optimization measures, uses the near-field communication structure 9 and the composite film to open a gap, and uses a conductive member to ground the copper foil and the display panel. The grounding area of ​​a single conductive member 34 is recommended to be greater than or equal to 5mm 2 The number of the conductive member 34 is at least one, which effectively improves the anti-static field and electrostatic protection capabilities of the display module.
