Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more particularly to a display device. Background Technology

[0002] Existing displays typically include a liquid crystal display (LCD) body, an electrostatic film attached to the front surface of the LCD body to eliminate static electricity, a conductive film for guiding and grounding static electricity, and a housing encapsulated outside the LCD body. The housing includes a base shell and a frame. A cavity is formed in the base shell, and perpendicular horizontal and vertical stepped portions are formed on the four walls of the cavity (top, bottom, left, and right). After assembly, the rear surface of the LCD body abuts against the vertical stepped portions of the four cavity walls. The end faces of the four sides of the LCD body are respectively positioned facing the horizontal stepped portions of the four cavity walls. These four horizontal stepped portions limit the LCD body in the top, bottom, left, and right directions. The frame is fastened to the front side of the LCD body to cooperate with the vertical stepped portions for front-rear positioning.

[0003] As is well known, during the assembly of an LCD panel, the LCD panel is typically moved horizontally from the front of the base shell into the cavity. Therefore, it is understandable that the dimension enclosed by the four horizontal stepped portions must be larger than the side of the LCD panel to create an installation gap that allows the LCD panel to enter the cavity. However, an unavoidable problem exists: a larger installation gap may cause the LCD panel to shift after being installed in the cavity. Therefore, engineers often design smaller installation gaps. However, because the horizontal stepped portions constrain the LCD panel along its entire length along the side, and because the base shell is often injection molded, controlling the straightness and flatness of the horizontal stepped portions is difficult. Poor straightness and flatness can cause significant installation errors. If a smaller installation gap is designed, the LCD panel may fail to be installed into the cavity due to interference during actual installation. Although the shape accuracy (such as straightness and flatness) of the horizontal step can be significantly improved by selecting a better injection mold, this comes at a high cost. Furthermore, after assembly, the horizontal step is covered by the frame, meaning it is not an exposed structure. Therefore, from this perspective, there is no need to improve the shape accuracy of the non-exposed structure.

[0004] In addition, the applicant’s earlier Chinese patent application, patent application number 202210850857.7, discloses a display device and electronic device. The conductor provided in the patent can effectively reduce the frame width occupied by the grounding structure and can provide a stable grounding state for the conductive film.

[0005] However, the applicant encountered the following problems when implementing the patent:

[0006] Because the conductor is directly fixed to the horizontal stepped portion of the lower cavity wall, the LCD screen body is often blocked by the conductor during the process of being horizontally fed into the cavity of the base shell, making it difficult for the LCD screen body to enter the cavity. As a result, the installation difficulty increases, and the smaller the installation gap, the greater the installation difficulty of the LCD screen body caused by the conductor. Summary of the Invention

[0007] In view of the above-mentioned technical problems existing in the prior art, embodiments of the present invention provide a display device.

[0008] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of the present invention is as follows:

[0014] The vertical stepped portion is provided with a plurality of rectangular embedding slots, which are arranged at intervals along the length of the side of the liquid crystal screen body, and one of the rectangular embedding slots corresponds to the position of the contact portion of the conductive film.

[0015] The display device further includes:

[0016] The support member includes multiple members, each of which is configured as a rectangular frame structure. The multiple support members are respectively installed in multiple rectangular embedding slots. Each support member has a first wall and a second wall facing away from each other. The second wall is used to abut against the bottom of the rectangular embedding slot, and the first wall is used to support the end face of the liquid crystal screen body. At least the first wall of the support member opposite to the conductive film is provided with a through slot.

[0017] A conductor is installed in the cavity of a support member opposite to the conductive film. The conductor has a guide portion and an elastic telescopic arm. The elastic telescopic arm contacts the abutment portion of the conductive film through a through groove. The guide portion is used for grounding.

[0018] Preferably, the conductor is configured as a rectangular frame structure; the side walls on both sides of the conductor are configured as inwardly bent sections; the top wall of the conductor is constructed by cutting to form a plurality of strip-shaped elastic telescopic arms arranged in sequence; a plurality of strip-shaped through slots are cut on the first wall of the support member, and the plurality of elastic telescopic arms pass through the plurality of through slots.

[0020] The plurality of elastic telescopic arms include two sets, the two sets of elastic telescopic arms are arranged symmetrically, and the area between the two sets of elastic telescopic arms forms a limiting plate, the limiting plate being used to abut against the inner side of the first wall.

[0021] Preferably, a notch is formed between the second wall of the supporting member and the outer wall of the supporting member, and a hollow groove is formed on the outer wall; wherein:

[0022] The guide portion includes a first contact arm and a second contact arm extending from the main body of the conductor; the first contact arm passes through the hollowed-out groove and abuts against the inner side of the frame; the second contact arm is located below the second wall through the notch;

[0023] The base shell has a perforation at the position opposite to the second contact arm, and a conductive tube is installed at the perforation. The upper end of the conductive tube has a contact point for abutting against the second contact arm.

[0024] Preferably, the bottom of the rectangular embedding groove has a clearance groove in the area corresponding to the second contact arm, and the second contact arm is submerged in the clearance groove.

[0031] Compared with the prior art, the beneficial effects of the display device disclosed in this invention are:

[0032] In the display device of the present invention, on the one hand, the liquid crystal screen body is limited by the support member on the horizontal step portion, rather than by the horizontal step portion itself, thereby effectively avoiding the difficulties caused by the shape error of the horizontal step portion to the assembly process of the liquid crystal screen body. On the other hand, since the conductor is placed in the support member, when assembling the liquid crystal screen body, only the elastic telescopic arm of the top wall of the conductor protrudes from the support member, thereby effectively reducing the difficulties caused by the conductor to the assembly process. Furthermore, the conductor is integrated into the support member, thereby avoiding the need to reserve space for the conductor separately and construct a separate installation structure, which is conducive to the compactness of the entire structure.

[0045] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0046] The present invention discloses a display device that can be used as a display screen for a television, a laptop computer, or an all-in-one computer. The present invention does not limit the application type of the display device.

[0047] like Figure 1 and Figure 2 As shown, the display device includes: a liquid crystal display (LCD) body 10, a backlight panel 40, an electrostatic film 20, a conductive film 30, a housing 50, a support member 60, and a conductor 70. The backlight panel 40 is disposed on the rear side of the LCD body 10, and the electrostatic film 20 is attached to the front surface of the LCD body 10, and the electrostatic film 20 covers the entire LCD body 10, that is, the four sides of the electrostatic film 20 are aligned with the four sides of the LCD body 10. The electrostatic film 20 is grounded to eliminate static electricity in the LCD body 10 to avoid display defects in the LCD body 10.

[0048] The conductive film 30 can be formed by bending a metal foil. Specifically, the conductive film 30 includes an attachment portion 31 and an abutment portion 32 that are integrally bent and perpendicular to each other. The conductive film 30 is placed on the bottom side of the liquid crystal screen body 10. Specifically, the conductive film 30 is placed in the middle of the bottom side, and the attachment portion 31 of the conductive film 30 is bonded to the outside of the electrostatic film 20, while the abutment portion 32 is located at the end face of the liquid crystal screen body 10.

[0049] The housing 50 has a shape that matches the LCD screen body 10, that is, the housing 50 is rectangular plate-shaped. The housing 50 includes a base shell 51 for accommodating the LCD screen body 10 and the backlight panel 40, and a frame 52 that is fastened to the front side of the LCD screen body 10 to encapsulate the LCD screen body 10. Specifically, a rectangular cavity with a shape matching the LCD screen body 10 is constructed in the base shell 51. Therefore, the cavity has four cavity walls, and a vertical step portion 512 and a horizontal step portion 511 are constructed on each cavity wall. The LCD screen body 10 is used to install in the cavity. Thus, the vertical step portion 512 stops at the rear side of the LCD screen body 10, and the four end faces of the LCD screen body 10 are respectively opposite to the four horizontal step portions 511. The frame 52 includes a vertical portion 521 and a horizontal portion 522 that are perpendicular to each other. After the frame 52 is fastened to the base shell 51, the vertical portion 521 is opposite to the LCD screen body 10 and limits the LCD screen body 10, while the horizontal portion 522 covers the bottom of the base shell 51.

[0050] It should be noted that the names of the vertical step portion 512 and the horizontal step portion 511 do not mean that they are always in a vertical state and a horizontal state, respectively. On the vertical cavity wall of the cavity, the horizontal step portion 511 is also in a vertical state.

[0051] In this invention, such as Figure 1 As shown, each horizontal step portion 511 is provided with multiple rectangular embedding slots 513, and among the multiple rectangular embedding slots 513 on the lower cavity wall of the cavity, there is one rectangular embedding slot 513 that is opposite to the conductive film 30.

[0052] In this invention, the support member 60 includes multiple members, and the multiple support members 60 are respectively installed in multiple rectangular embedding slots 513. For example Figures 2 to 4 As shown, the support member 60 is constructed as a rectangular frame structure. Specifically, the support member 60 includes, as shown in the figure... Figure 2 The diagram shows a first wall 61 and a second wall 62 facing away from each other, as well as inner and outer side walls 63 located on both sides. After the support member 60 is installed in the rectangular recess 513, the second wall 62 abuts against the bottom of the rectangular recess 513, and the first wall 61 faces the end face of the liquid crystal screen body 10. In this invention, the first wall 61 protrudes beyond the horizontal step portion 511 by a predetermined distance, thereby enabling the first wall 61 to limit the position of the support liquid crystal screen body 10 without relying on the horizontal step portion 511 itself to limit the position of the liquid crystal screen body 10.

[0053] In this invention, the conductor 70 is installed in the inner cavity of the support member 60 corresponding to the conductive diaphragm 30. The support member 60 corresponding to the conductive diaphragm 30 is constructed as follows: two sets of strip-shaped through grooves 64 are formed on the first wall 61, the two sets of strip-shaped through grooves 64 are symmetrically arranged, each set of strip-shaped through grooves 64 is arranged in sequence at intervals, and each set of through grooves 64 extends synchronously to the side wall of the support member 60.

[0054] like Figure 6 , 7 and combined Figure 2 , Figure 3 As shown, the conductor 70 is constructed as follows: the conductor 70 is constructed as a rectangular frame structure, including a top wall 71, a bottom wall 72, and two side walls 73. Two sets of elastic telescopic arms 74 are constructed on the top wall 71. The two sets of elastic telescopic arms 74 are symmetrically arranged and correspond to two sets of through slots 64. Thus, the two sets of elastic telescopic arms 74 pass through the two sets of through slots 64 and abut against the contact portion 32 of the conductive film 30 with a certain elastic preload. Furthermore, a guide portion is constructed on the conductor 70 to ground the conductor 70, thereby grounding the conductive film 30.

[0055] In a more preferred configuration of conductor 70, inwardly bent portions are constructed on the two sidewalls 73 of conductor 70, thereby improving the elasticity of the elastic telescopic arm 74.

[0056] The advantages of a display device with a support member 60 and a conductor 70 are described below:

[0057] In the display device of the present invention, on the one hand, the support member 60 on the horizontal step portion 511 is used to limit the liquid crystal screen body 10, rather than the horizontal step portion 511 itself, thereby effectively avoiding the difficulties caused by the shape error of the horizontal step portion 511 to the assembly process of the liquid crystal screen body 10. On the other hand, since the conductor 70 is placed in the support member 60, when assembling the liquid crystal screen body 10, only the elastic telescopic arm 74 of the top wall 71 of the conductor 70 protrudes from the support member 60, thereby effectively reducing the difficulties caused by the conductor 70 to the assembly process. Furthermore, the conductor 70 is integrated into the support member 60, thereby avoiding the need to reserve space for the conductor 70 separately and construct a separate installation structure, which is conducive to the compactness of the entire structure.

[0058] In some preferred embodiments, the support member 60 corresponding to the conductive film 30 and the conductor 70 are configured as follows:

[0059] The conductor 70 has a guide portion including a first contact arm 761 and a second contact arm 762, the first contact portion extending outward and the second contact arm 762 located at the bottom of the conductor 70.

[0060] A slot 632 is formed on the outer wall 63 of the support member 60. The first contact arm 761 passes through the slot 632 and contacts the inner side of the vertical part 521 of the frame 52. A notch 621 is formed in the area between the second wall 62 and the outer wall 63 of the support member, so that the second wall 62 has a free end, and the second contact arm 762 is located below the second wall 62 through the notch 621. Correspondingly, a clearance groove 514 is formed in the area opposite to the second contact arm 762 at the bottom of the rectangular embedding groove 513, and the second contact arm 762 is recessed in the clearance groove 514. Preferably, the outer wall 63 of the support member 60 and the support member 60 form a detachable mating structure 633, so that the conductor 70 can be installed into the support member 60 when the outer wall 63 is in a detached state.

[0061] like Figure 2 As shown, a perforation is made in the area corresponding to the end of the base shell 51 and the second contact arm 762. A conductive tube 80 is installed in the perforation. The upper end of the conductive tube 80 has a contact point for abutting against the second contact arm 762. The lower end of the conductive tube 80 has a threaded hole, which is connected to the threaded hole by a metal connector 81. An auxiliary interface 82 is made in the area corresponding to the perforation in the horizontal part 522 of the frame 52. An external lead is connected to the conductive tube 80 through the auxiliary interface 82.

[0062] The advantages of the above-mentioned preferred structure are:

[0063] Conductor 70 provides two grounding schemes: grounding via the first contact arm 761 or grounding via the second contact arm 762. If the frame 52 is a metal frame 52, grounding can be achieved using the first contact arm 761 and the frame 52. In this case, it is not necessary to connect a lead to the auxiliary interface 82 of the frame 52. However, if the frame 52 is a non-conductive frame 52, for example, if it is a plastic frame 52, then a lead is connected to the auxiliary interface 82 of the frame 52 to achieve grounding.

[0064] In some more preferred embodiments, the first contact arm 761 is configured as a U-shape after a second bend, so that the first contact arm 761 contacts the inner side of the vertical portion 521 of the frame 52 in an elastically pre-tightened manner, thereby improving the stability of the contact.

[0065] In some preferred embodiments, a limiting plate 75 is formed in the area between the two sets of elastic telescopic arms 74. The limiting plate 75 is used to abut against the inner side of the first wall 61, thereby limiting the maximum protrusion of the elastic telescopic arms 74.

[0066] In some more preferred embodiments, the rectangular embedding groove 513 extends through the front surface of the base shell 51, and an inclined insert plate 631 is formed at the lower edge of the outer side wall 63 of the support member 60; an inclined slot 515 is formed on the outer surface of the base shell 51; the insert plate 631 is inserted into the slot 515; an elastic member is provided between the insert plate 631 and the bottom of the slot 515, and the elastic member is composed of two intersecting plates. By constructing this structure, the support member 60 is assembled with the base shell 51 in an inclined approach, thereby avoiding interference between the second contact arm 762 below the support member 60 and the bottom of the rectangular embedding groove 513 during the installation of the support member 60, and giving the support member 60 a certain amount of floating, which is beneficial for installing the LCD screen body 10.

[0067] In some preferred embodiments, the support member 60 is manufactured using an injection molding process. The conductor 70 is formed by bending a metal plate; the first contact arm 761 and the second contact portion are formed by cutting on the metal plate.

[0068] In some preferred embodiments, such as Figure 4 and Figure 6 As shown, the bottom wall 72 of the conductor 70 is fixed to the second wall 62 of the support member 60 by fasteners. Specifically, perforated holes 611 are provided on the first wall 61 of the support member 60 and on the top wall 71 of the conductor 70, so as to facilitate the insertion of tools such as screwdrivers to tighten the fasteners.
