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 apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The display device in the related art includes a metal housing having an accommodating space, a foam tape, and a display panel accommodated in the accommodating space. During assembly, firstly, the foam adhesive tape is adhered to three edges of the bottom wall of the metal shell, namely the left edge, the upper edge and the right edge; then, the side of the display panel to which the copper foil sheet is attached, that is, the back side of the display panel is attached to a foam tape, and the display panel is fixed to the metal case by means of tape attachment.

Wherein the copper foil is in contact with the metal housing. On one hand, the copper foil conducts heat generated in the working process of the display panel to the metal shell for heat dissipation, and on the other hand, the copper foil is in contact with the metal shell for grounding so as to shield interference of electric elements such as a driving circuit and the like on the display performance of the display panel.

Above-mentioned mode through bubble cotton tape-stripping is fixed in the casing with display panel, has following not enough:

after the display device is used for a period of time, especially when the display device is operated in a high-temperature environment, or in the reliability testing process of high temperature and the like before the product leaves a factory, the foam adhesive tape is used for a long time or is in a high-temperature state for a long time, so that the viscosity of the foam adhesive tape is weakened or loses efficacy, and the display panel and the shell are separated due to unstable fixation. Therefore, the display panel is assembled by gluing, and the reliability is poor.

In addition, the display panel is usually attached to the edge of the housing through a foam adhesive tape, and the attachment area is narrow, so that a certain gap exists between most of the surface area (such as the middle area of the display panel) of the display panel and the metal housing, which causes insufficient or separated contact area between the copper foil attached to the back surface of the display panel and the bottom wall of the metal housing, and affects heat dissipation performance and grounding performance.

In view of this, the present disclosure provides a display device, in which a display panel is fixed to a housing by a magnetic attraction manner, so that the stability of fixing between the display panel and the housing can be improved, and the heat dissipation performance and the grounding performance of the display panel can also be improved. The display panel and the method can solve the problems that in the prior art, the foam adhesive tape is used for a long time, or the display panel is not enough in viscosity or fails in a high-temperature environment, so that the display panel is separated from the shell, and the reliability of the whole machine is poor.

The display device 100 further may include a front case and a rear case. The assembled front and rear cases define a receiving space for receiving and wrapping the display panel 20 and the housing 10 in the receiving space.

In some application scenarios, the housing 10 of the display device 100 of the present disclosure may refer to a middle frame, such as a middle frame of a mobile phone, a front case may refer to a front cover plate, and a rear case may refer to a rear cover.

The present disclosure is not limited thereto, and the housing 10 may also be a component for supporting the display panel 20 in other terminal devices, for example, a frame for supporting a display screen in a smart television.

Taking a mobile phone as an example, in the display device 100 of the present disclosure, the housing 10 may include a first surface 11, a second surface (not shown) opposite to the first surface 11, and a side surface extending toward the display panel 20. The side surface of the housing 10 surrounds the first surface 11 of the housing 10 and extends toward the display panel 20, and the side surface of the housing 10 and the first surface 11 of the housing 10 together form an accommodating space in which the display panel 20 can be accommodated.

The first side 11 of the housing 10 may be used to support the back side of the display panel 20, and the second side may be used to fixedly mount a battery, a circuit board, and various functional units electrically connected to the circuit board, such as a radio frequency unit for receiving, transmitting, and processing high frequency radio electromagnetic waves. When assembling, the rear cover and the front shell are fixed to define a receiving space, so that the housing 10, the battery, the display panel 20, the circuit board, and the functional units are received and wrapped in the receiving space.

The first surface 11 may be a bottom wall (hereinafter, may also be referred to as the bottom wall 11) of the housing 10 facing the back surface of the display panel 20, and the side surfaces may be four side walls extending in the direction of the display panel 20 around the first surface 11, that is, a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15.

The bottom wall 11 and the four sidewalls together form an accommodating space having an opening facing the display panel 20 for accommodating the display panel 20. In addition, the accommodating space may also be used to accommodate other components associated with the display panel 20. For example, a driving circuit, electric devices, and the like required for the display panel 20 may be accommodated. The housing 10 formed by the first surface 11, the first sidewall 12, the second sidewall 13, the third sidewall 14 and the fourth sidewall 15 may be an integral housing made of any material, such as a metal or resin material. The housing 10 may be manufactured by forging, injection molding, cutting or other means.

In some embodiments, the housing 10 may be constructed from multiple pieces secured together, i.e., not integrally formed. For example, the bottom wall 11 of the housing 10 may be formed by fixing two or more structures, and the materials of the two or more structures may be different. The side walls of the housing 10 may be formed of a single structure or formed of two or more structures. In some application scenarios, the side wall may also refer to a bezel, such as a side bezel of a cell phone.

Further, the shape of the housing 10 may be any desired shape, such as a rectangular housing as is common in cell phones, a circular housing or an oval housing in smartwatches, etc.

The display panel 20 includes a display surface 201 and a back surface 202 opposite the display surface 210. The display surface 201 is used to display images for viewing by a user or to provide an interactive interface for the user. The display panel 20 may be any desired display screen, for example, a liquid crystal display panel, such as an LCD display panel, an LED display panel, an Organic Light Emitting Diode (OLED) display panel, or the like. In addition, the display panel 20 may also be a flexible display panel, i.e., a flexible OLED display panel. The present disclosure is illustrated by taking a flexible display panel as an example, but the present disclosure is not limited thereto.

Referring to fig. 4, the display panel 20 may be a flexible display panel, such as a flexible OLED display panel, including a light emitting layer 21, a circuit layer 22, a glue layer 23, and a substrate layer 24, which are sequentially stacked. The light emitting layer 21 serves as a display surface of the display panel 20 for displaying a desired image, and the flexible substrate layer 24 may serve as a back surface of the display panel 20, that is, a mounting surface of the display panel 20. However, the present disclosure is not limited thereto, and the mounting surface of the display panel 20 may be a side surface of the display panel 20.

The back surface of the display panel 20 may be any desired functional layer attached to the substrate layer 24, such as a buffer layer, a support layer, a touch sensitive layer, a heat conductive layer, and the like.

The display surface of the display panel 20 may also be covered with a protective front cover, such as a front cover of a mobile phone. A sealing member may be disposed between the edge of the display panel 20 and the side of the casing 10 to prevent dust and moisture from entering and damaging the display panel 20, so as to prolong the service life of the display device 100. The sealing element can be sealant, sealing rubber pad, etc.

The display device 100 of the present disclosure fixes the display panel 20 to the housing 10 by a magnetic adsorption manner, i.e. a glue-free fixing manner is used, compared with a conventional tape-bonding manner, since the magnetic adsorption is influenced by external factors to a minimum, a risk that the display panel 20 is separated from the housing 10 due to a long-term use or a viscous failure in a high-temperature environment in the conventional tape-bonding manner is avoided, so that the contact stability when the display panel 20 is fixed to the housing 10 is improved; meanwhile, the contact stability is improved, so that the grounding performance of the display panel 20 is also ensured, and the interference of a driving circuit of the display panel 20 on a radio frequency unit due to poor grounding is avoided; moreover, the heat generated by the display panel 20 during operation can be instantly conducted to the housing 10, and the heat dissipation performance is effectively ensured, so that the reliability of the whole device is enhanced.

In addition, since the display panel 20 and the housing 10 are assembled by magnetic attraction, the assembly efficiency is improved, and the user or the maintenance personnel can be helped to separate the display panel from the housing quickly during the subsequent maintenance. Therefore, compared with a tape-bonding mode, the display device has higher convenience in assembly and subsequent maintenance. In some embodiments, the display device 100 includes a liquid crystal display including a liquid crystal display panel and a backlight module disposed behind the liquid crystal display panel. The liquid crystal display panel 20 may include an upper polarizer, a color filter, a liquid crystal layer, a glass substrate, and a lower polarizer, which are sequentially stacked; the backlight module may include a metal back plate, a reflection plate, a light guide plate, a diffusion sheet, and a prism sheet, which are sequentially stacked to function as a backlight, and a light source at one end of the metal back plate. Wherein one or both of the metal back plate (i.e., the bezel) and the case 10 are metal components having magnetism. The housing 10 may be a metal housing or a portion thereof may be a metal part.

For example, the metal back plate may be magnetized to obtain magnetism, and the display panel 20 may be fixed to the housing 10 by magnetically attracting the housing 10 through the metal back plate having magnetism.

Alternatively, the housing 10 is magnetized to obtain magnetism, and the metal back plate is magnetically attracted by the housing 10 having magnetism, so that the display panel 20 is fixed to the housing 10.

Alternatively, the housing 10 and the metal back plate are magnetized to obtain magnetism, and the display panel 20 is fixed to the housing 10 by magnetic attraction between the housing 10 having magnetism and the metal back plate having magnetism, so as to further improve the stability of the magnetic attraction.

The present disclosure is not limited to the magnetic attraction with the housing 10 by the magnetization process of the metal back plate on the back surface of the liquid crystal display panel. If possible, the display panel may be fixed to the housing by magnetizing the metal components of the other display panels to obtain magnetism, and attracting the metal components to the housing 10. For example, a heat conductive metal plate of a rear substrate of an Organic Light Emitting Diode (OLED) display panel is magnetized to obtain magnetism to attract the case.

In the present embodiment, it is not necessary to additionally provide any fixing component between the display panel 20 and the housing 10, and the display panel 20 is magnetically attracted and fixed to the housing 10 by using the metal back plate located on the back surface of the liquid crystal display panel and the metal part of the housing 10 itself in the liquid crystal display screen to obtain magnetism through magnetization treatment, so that the material and processing costs are greatly reduced while the stability, heat dissipation performance and grounding performance of the magnetic attraction and fixation are ensured.

In some embodiments, the display device 100 further includes a magnetic component 30, and the display panel 20 is magnetically attracted to the housing 10 by the magnetic component 30. The magnetic component 30 may include a first magnetic component 32 capable of attracting the housing 10, and the display panel 20 is fixed to the housing 10 by the first magnetic component 32 through magnetic attraction.

The housing 10 is supported on the back surface of the display panel 20, i.e., the first surface 11 of the housing 10 faces the back surface of the display panel 20. For example, the first magnetically attractive part 32 may be attached to the back side 202 of the display panel 20 by glue. The housing 10 is a metal housing or a part of a metal part corresponding to the first magnetic part 32.

The display panel 20 is held and fixed to the housing 10 by the first magnetic attraction member 32 and the first face 11 of the housing 10.

In order to prevent the first magnetic attraction part 32 from occupying too much of the display area of the display surface 201 of the display panel 20, the first magnetic attraction part 32 may be adhered to an edge of the display surface 201 by glue, for example, may be disposed around the periphery of the display surface 201.

The metal plate may serve as a substrate of the display panel 20, and the rigidity thereof may also serve as a support for the display panel 20. Correspondingly, the second magnetic part 31, i.e. the magnet, can be fixed on the first surface 11 or the side wall of the housing 10. The second magnetic attracting member 31 may be a magnet provided separately from the housing 10 or a metal member having magnetism subjected to magnetization processing, or the second magnetic attracting member 31 may be a metal member having magnetism subjected to magnetization processing formed by a part of the housing 10.
