Description

Technical Field

[0001] The present disclosure relates to the technical field of terminal equipment, and in particular to a screen module and a terminal equipment. Background Art

[0002] The screen module is a component on a terminal device used to display information. The panel and driver chip in the screen module are important components that support the display function of the screen module. The driver chip is electrically connected to the panel, thereby controlling the display on the panel.

[0003] Usually, the screen module includes a panel, a support plate and a driver chip. The support plate is located between the panel and the driver chip and is used to support the panel. Since the support plate is located between the panel and the driver chip, in order to achieve electrical connection between the panel and the driver chip, one end of the panel is bent toward the driver chip so that it bypasses the side of the support plate and extends to the side of the support plate close to the driver chip. Then, the driver chip is fixed to the panel on the side of the support plate close to the driver chip, thereby achieving electrical connection between the panel and the driver chip.

[0004] In the terminal device, the glass cover plate in the screen module will be connected to the border of the middle frame, and the driver chip will be set toward the mounting plate of the middle frame. However, due to the current demand for thin and light terminal devices, the thickness of the mounting plate is relatively small, which makes it easy for the mounting plate of the middle frame to deform when the terminal device falls, hitting the driver chip or the bent panel, and then causing display failure.

[0062] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0063] The present disclosure provides a screen module 1, see Figure 1 , Figure 2 and Figure 3 The screen module 1 includes a panel 11, a first support member 12, a driving chip 13 and a protective member 14.

[0064] The panel 11 (or panel) includes a display portion 111, a connecting portion 112 and a bending portion 113. The display portion 111 and the connecting portion 112 have a planar structure, and the bending portion 113 has an arc structure. Two ends of the bending portion 113 are respectively connected to the display portion 111 and the connecting portion 112.

[0065] The display portion 111 , the bending portion 113 , and the connecting portion 112 are electrically connected in sequence, that is, the connecting portion 112 is electrically connected to the display portion 111 through the bending portion 113 , and the electrical connection can be achieved through metal wires such as copper wires.

[0066] The first support member 12 is located between the display portion 111 and the connecting portion 112 , and is connected to the display portion 111 .

[0067] The driver chip 13 is located on a side of the connection portion 112 away from the display portion 111 . The driver chip 13 is connected and electrically connected to the connection portion 112 . In this way, the driver chip 13 can be electrically connected to the display portion 111 through the connection portion 112 and the bending portion 113 .

[0068] The display unit 111 has a pixel circuit for displaying images to the outside of the screen module 1. In the above structure, the arrangement of the bending portion 113 enables the panel 11 to bypass the side of the first support member 12 to achieve electrical connection with the driving chip 13, so that the driving chip 13 can control the display unit 111 to display images.

[0069] The protective member 14 includes a supporting portion 141 and a protective portion 142. The supporting portion 141 is located on a side of the first supporting member 12 away from the display portion 111 and is connected to the first supporting member 12. The protective portion 142 is located on a side of the driving chip 13 away from the connecting portion 112. The edge of the protective portion 142 is connected to the supporting portion 141.

[0070] In this way, the two ends of the supporting portion 141 are respectively connected to the first supporting member 12 and the protecting portion 142, so as to surround and protect the connecting portion 112 and the driving chip 13 located between the first supporting member 12 and the protecting portion 142. When the screen module 1 is installed in the terminal device, the protecting portion 142 will be located between the driving chip 13 and the mounting plate 22 of the middle frame 2 of the terminal device. When falling, even if the mounting plate is deformed, it will only collide with the protecting portion 142, and will not directly collide with the connecting portion 112 and the driving chip 13, thereby reducing the risk of display failure caused by collision of the connecting portion 112 or the driving chip 13 during the falling process, and improving the stability and service life of the terminal device.

[0071] In addition, the support portion 141 ensures the distance between the first support member 12 and the protective portion 142. Therefore, when the protective portion 142 is hit by the mounting plate 22 of the middle frame 2, the support portion 141 will also support and protect the connecting portion 112 between the first support member 12 and the protective portion 142 and the driver chip 13, thereby reducing the risk of display failure and improving the stability and service life of the terminal device.

[0072] In a possible implementation, the protective member 14 may be made of any material with a certain strength, for example, steel, aluminum alloy, stainless steel, etc., which is not specifically limited in the embodiment of the present disclosure.

[0073] In one possible implementation, see Figure 1 and Figure 2 The screen module 1 may further include other functional film layers 18, which may include a cover plate 181, an optical adhesive layer 182 and a polarizer 183. The cover plate 181, the optical adhesive layer 182, the polarizer 183, the display unit 111 and the first support member 12 are stacked in sequence, wherein the edge of the cover plate 181 may be used to connect to the frame 21 of the middle frame 2 of the terminal device, thereby realizing the connection between the screen module 1 and the middle frame 2.

[0074] In a possible implementation, the screen module 1 may further include a UV (Ultraviolet Rays) adhesive layer 19, which is located on the outer arc surface of the bending portion 113 and connected to the outer arc surface of the bending portion 113, thereby protecting and shading the bending portion 113 through the UV adhesive layer 19.

[0075] Understandably, Figure 1 and Figure 3 The protection part 142 shown is not suspended, but connected to the support part 141. Figure 1 and Figure 3 The cross-sectional schematic diagram does not show the connection structure. Figure 2 yes Figure 1 Schematic diagram of the cross section of AA in Figure 2 It can be seen that the protection portion 142 is connected to the support portion 141 .

[0076] The structure of the protective member 14 is further described below by taking several possible structures as examples:

[0077] In the embodiments of the present disclosure, see Figure 2 The structure of the protective member 14 can be: the supporting portion 141 can include a first connecting plate 1411 and a second connecting plate 1412, the first connecting plate 1411 is located between the first supporting member 12 and the connecting portion 112, and is connected to the first supporting member 12, the first end of the second connecting plate 1412 is connected to the first connecting plate 1411, and the second end of the second connecting plate 1412 is connected to the protective portion 142.

[0078] In this way, the first connecting plate 1411 is used to connect with the first supporting member 12 , and the second connecting plate 1412 is used to connect the first connecting plate 1411 and the protecting portion 142 , thereby achieving a stable connection between the first supporting member 12 and the protecting portion 142 .

[0079] Furthermore, the first connecting plate 1411 is located between the first supporting member 12 and the connecting portion 112 , and the first connecting plate 1411 has a certain strength, and can also play a certain supporting role on the panel 11 .

[0080] In one possible implementation, see Figure 2 and Figure 4, the protection part 142 may have a plate-like structure. The number of the first connecting plate 1411 may be one, and the plane where the first connecting plate 1411 is located is parallel to the plane where the protection part 142 is located. The number of the second connecting plates 1412 is two, and the planes where the two second connecting plates 1412 are located are perpendicular to the plane where the protection part 142 is located, and the first ends of the two second connecting plates 1412 are respectively connected to the opposite ends of the first connecting plate 1411, and the second ends of the two second connecting plates 1412 are respectively connected to the opposite ends of the protection part 142.

[0081] In this way, a Figure 4 The protective member 14 shown has a tubular structure with a U-shaped cross-section, and the connecting portion 112 and the driving chip 13 are located inside the tubular structure of the protective member 14. When the protective portion 142 of the protective member 14 is hit by the mounting plate 22, the protective member 14 will protect the connecting portion 112 and the driving chip 13 inside it, thereby reducing the risk of display failure.

[0082] The lengths of the first connecting plate 1411 , the second connecting plate 1412 and the protecting portion 142 in the extending direction of the tubular structure may be the same, thereby simplifying the structure and improving the manufacturing efficiency of the protecting member 14 .

[0083] In another possible implementation, see Figure 5 and Figure 6 The protection part 142 has a plate-like structure, the number of the first connecting plates 1411 is two, the planes where the two first connecting plates 1411 are located are coplanar and parallel to the plane where the protection part 142 is located. The number of the second connecting plates 1412 is two, the planes where the two second connecting plates 1412 are located are perpendicular to the plane where the protection part 142 is located, the first ends of the two second connecting plates 1412 are respectively connected to one first connecting plate 1411, and the second ends of the two second connecting plates 1412 are respectively connected to the opposite ends of the protection part 142.

[0084] In this way, a Figure 5 The protective member 14 shown has a tubular structure with a C-shaped cross-section, and the connecting portion 112 and the driving chip 13 are located inside the tubular structure with a C-shaped cross-section. When the protective portion 142 of the protective member 14 is hit by the mounting plate 22, the protective member 14 will protect the connecting portion 112 and the driving chip 13 inside it, thereby reducing the risk of display failure.

[0085] Furthermore, the protective member 14 is configured in a C-shape, which makes it easier to install the protective member 14 in the screen module 1 , thereby improving the installation convenience of the screen module 1 .

[0086] Likewise, the lengths of the first connecting plate 1411 , the second connecting plate 1412 and the protective portion 142 in the extending direction of the tubular structure may be the same, thereby simplifying the structure and improving the manufacturing efficiency of the protective member 14 .

[0087] See also Figure 6 There may be a certain gap between the opposite ends of the two first connecting plates 1411 , or the gap between the two ends may be filled with materials such as foam or adhesive, thereby improving the flatness between each layer of the screen module 1 .

[0088] In another possible implementation, the protective member 14 may be Figure 4 As shown, it includes a first connecting plate 1411, which can also be Figure 5 The protective member 14 also includes a plurality of support columns (not shown in the figure), which are evenly distributed on both sides of the connecting portion 112 and the driving chip 13, and the two ends of the support columns are respectively connected to the first support member 12 and the protective portion 142.

[0089] In this way, the first connecting plate 1411 , the plurality of supporting columns and the protective portion 142 can surround the connecting portion 112 and the driving chip 13 therein, thereby protecting them and reducing the risk of display failure of the screen module 1 .

[0090] In the embodiment of the present disclosure, the structure of the protective member 14 can also be: the supporting part 141 includes a plurality of second connecting plates 1412, and the plurality of second connecting plates 1412 are evenly distributed on both sides of the connecting part 112 and the driving chip 13, and the first end of the second connecting plate 1412 is connected to the first supporting part 12, and the second end of the second connecting plate 1412 is connected to the protective part 142. In this way, the first supporting part 12, the plurality of second connecting plates 1412 and the protective part 142 form a structure surrounding the connecting part 112 and the driving chip 13, which protects the connecting part 112 and the driving chip 13 and reduces the risk of display failure of the screen module 1.

[0091] The above are only several possible structures of the protective member 14 in the embodiment of the present disclosure. It may also be other reasonable structural settings, and the embodiment of the present disclosure is not limited to this.

[0092] The structure of the first support member 12 is further described below by taking several possible structures as examples:

[0094] The two sides of the first back plate a are respectively attached to the display portion 111 and the first foam layer b. The first back plate a is used to support the panel 11 , especially the display portion 111 .

[0095] The side of the first foam layer b away from the first back plate a is in contact with the copper foil c, and the first foam layer b plays a role of buffering and protection in the screen module 1.

[0096] A side of the copper foil c away from the first foam layer b is connected to the connecting portion 112 , and the copper foil c is also connected to the supporting portion 141 .

[0097] When the support portion 141 includes a first connecting plate 1411, the side of the copper foil c away from the first foam layer b is in contact with the first connecting plate 1411, the side of the first connecting plate 1411 away from the copper foil c is in contact with the connecting portion 112, and the second connecting plate 1412 is connected to the first connecting plate 1411; when the first connecting plate 1411 is not provided in the support portion 141 and the connection between the first support member 12 and the protective portion 142 is realized only by the second connecting plate 1412, the side of the copper foil c away from the first foam layer b is directly in contact with the connecting portion 112, and the second connecting plate 1412 is connected to the copper foil c.

[0100] In this way, the second back plate d is provided to further support the panel 11 , especially the connecting portion 112 of the panel 11 , thereby improving the stability of the screen module 1 .

[0102] In this way, when the curvature of the bending portion 113 is large, if the thickness of the first support member 12 is not enough to support the curvature of the bending portion 113, a padding layer e can be provided to fill the gap between the display portion 111 and the connecting portion 112 so that the curvature of the bending portion 113 meets the requirements.

[0103] Among them, the padding layer e can be any reasonable material, for example, it can be foam to further improve the cushioning effect, and for example, it can be glue or double-sided tape, etc., which can not only adhere the copper foil c to the connecting part 112, but also fill the gap of insufficient thickness.

[0107] When the supporting portion 141 includes a first connecting plate 1411, the display portion 111, the first back panel a, the first connecting plate 1411, the first foam layer b, the copper foil c, the second back panel d and the connecting portion 112 are stacked in sequence, and the second connecting plate 1412 is connected to the first connecting plate 1411; when the first connecting plate 1411 is not provided in the supporting portion 141 and only the second connecting plate 1412 is used to realize the connection between the first supporting member 12 and the protective portion 142, the display portion 111, the first back panel a, the first foam layer b, the copper foil c, the second back panel d and the connecting portion 112 are stacked in sequence, and the second connecting plate 1412 is connected to the first back panel a.

[0108] In this way, when the mounting plate 22 collides with the protective part 142, the first back panel a, the supporting part 141 and the protective part 142 will protect the various components inside thereof (including the first foam layer b, the copper foil c, the second back panel d, the connecting part 112 and the driving chip 13), thereby reducing the risk of display failure of the screen module 1.

[0109] In one possible implementation, see Fig. 9 The second support member 15 also includes a cushioning layer e, the display part 111, the first backplane a, the first foam layer b, the copper foil c, the cushioning layer e, the second backplane d and the connecting part 112 are stacked in sequence, and the first backplane a is connected to the support part 141.

[0110] The above are only several possible structures of the first support member 12 in the embodiment of the present disclosure. It may also be other reasonable structural settings, and the embodiment of the present disclosure is not limited to this.

[0111] In the embodiment of the present disclosure, in order to further reduce the risk of display failure of the screen module 1, the following structure may also be provided:

[0112] In the embodiments of the present disclosure, see Figure 1 and Figure 2 There is a first gap between the protective part 142 and the driver chip 13. In this way, when the protective part 142 is hit by the mounting plate 22 of the middle frame 2, there is still a gap between the protective part 142 and the driver chip 13, and there is also a certain gap between the protective part 142 and the connecting part 112, thereby reducing the risk of the connecting part 112 and the driver chip 13 being hit, thereby reducing the risk of display failure of the screen module 1.

[0113] In one possible implementation, see Fig.10 A surface of the protection portion 142 close to the driving chip 13 has a first step groove 1421 , the first step groove 1421 is directly opposite to the driving chip 13 , and a first gap is formed between the first step groove 1421 and the driving chip 13 .

[0114] In this way, the first break groove 1421 can be set only at the position on the protective part 142 that is opposite to the driving chip 13 to ensure the gap between the protective part 142 and the driving chip 13. The other positions of the protective part 142 only need to have a certain gap with the connecting part 112, and there is no need to be located in the same plane as the bottom of the first break groove 1421, thereby reducing the space occupied by the protective part 14 and improving space utilization.

[0115] The distance between the bottom of the first step groove 1421 and the driving chip 13 may be the same as the distance between the portion of the protection portion 142 other than the first step groove 1421 and the connecting portion 112 .

[0116] In one possible implementation, see Fig.11 The screen module 1 may further include a second foam layer 16 , which is located in the first gap and is respectively connected to the driving chip 13 , the connecting portion 112 , and the protective portion 142 .

[0117] In this way, when the protection part 142 is impacted by the mounting plate 22 , the second foam layer 16 can further buffer and protect the driving chip 13 and the connecting part 112 , thereby reducing the risk of display failure of the screen module 1 .

[0118] It is understandable that the second foam layer 16 may be interference filled between the connecting portion 112 and the protective portion 142 , that is, the second foam layer 16 is always in a compressed state, thereby improving the protective effect of the second foam layer 16 .

[0119] In the embodiments of the present disclosure, see Fig.12 The screen module 1 may further include an insulating film layer 17 , which is located between the driving chip 13 and the protection portion 142 , and is connected to the driving chip 13 and the connecting portion 112 .

[0120] In this way, when the protection portion 142 is impacted by the mounting plate 22 , the insulating film layer 17 can further protect the driving chip 13 and the connecting portion 112 , thereby reducing the risk of display failure of the screen module 1 .

[0121] The above are only several possible structural settings of the screen module 1 in the embodiment of the present disclosure. The screen module 1 in the embodiment of the present disclosure may also have other reasonable structural settings, and the embodiment of the present disclosure is not limited to this.

[0122] The present disclosure also provides a terminal device, see Figure 3 The terminal device includes a middle frame 2 and a screen module 1 as described in any one of the above items.

[0123] The middle frame 2 includes a frame 21 and a mounting plate 22 . The mounting plate 22 is located in the frame 21 and connected to the frame 21 .

[0124] The screen module 1 is located at one side of the mounting plate 22 and connected to the frame 21 . A second gap is defined between the protection portion 142 and the mounting plate 22 .

[0125] By adopting the present disclosure, when the terminal device falls, even if the mounting plate 22 is deformed and touches the screen module 1, it will not directly collide with the panel 11 and the driver chip 13, but will only collide with the protective part 142. The first support member 12 and the protective member 14 protect the internal connection part 112 and the driver chip 13, thereby reducing the risk of display failure of the screen module 1 and improving the stability and service life of the terminal device.

[0126] In one possible implementation, see Fig.13 A surface of the mounting plate 22 close to the protection portion 142 has a second step groove 221 , and the second step groove 221 is directly opposite to the position of the driving chip 13 .

[0127] The provision of the second step groove 221 reduces the possibility that the mounting plate 22 is deformed and hits the screen module 1 when falling, thereby reducing the risk of display failure of the screen module 1 and improving the stability and service life of the terminal device.

[0128] In a possible implementation, the distance between the protective part 142 and the mounting plate 22 is less than the preset distance. Since the protective member 14 can provide sufficient protection for the panel 11 and the driver chip 13, and avoid the problem of display failure caused by falling, the distance between the protective part 142 and the mounting plate 22 can be set to be less than the preset distance, thereby reducing the distance between the protective part 142 and the mounting plate 22, thereby reducing the overall thickness of the terminal device, which is conducive to the demand for a thin and light body of the terminal device.

[0129] In one possible implementation, see Fig.13 The terminal device may further include hot melt adhesive 3 , and the cover plate 181 of the screen module 1 and the frame 21 are connected with each other through the hot melt adhesive 3 .

[0130] In one possible implementation, see Fig.13 The terminal device further includes a flexible circuit board 4 , one end of which may be located on a side of the connecting portion 112 away from the display portion 111 and electrically connected to the connecting portion 112 .

[0131] Since the connection portion 112 is also electrically connected to the driver chip 13, the flexible circuit board 4 can also be electrically connected to the driver chip 13 through the connection portion 112, so that the panel 11, the driver chip 13 and other components in the terminal device can be electrically connected through the flexible circuit board 4. For example, the terminal device may also include a mainboard, which is electrically connected to the flexible circuit board 4, so that the mainboard can control the driver chip 13 and the panel 11 through the flexible circuit board 4.

[0132] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0133] The disclosed embodiment provides a screen module 1, in which the protective member 14 includes a supporting portion 141 and a protective portion 142, the supporting portion 141 is connected to the first supporting portion 12, and the edge of the protective portion 142 is connected to the supporting portion 141, so that the first supporting portion 12, the supporting portion 141 and the protective portion 142 can surround and protect the connecting portion 112 of the panel 11 and the driving chip 13, even if the mounting plate 22 of the middle frame 2 is deformed when the terminal device falls, the mounting plate 22 will only collide with the protective portion 142, and will not affect the connecting portion 112 and the driving chip 13 therein, thereby reducing the risk of display failure.

[0134] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
