Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a display device. Background Art

[0002] With the development of society, interactive touch electronic devices have been widely used in education, conferences, medical devices and other fields.

[0003] Existing interactive electronic devices include a display screen and a housing. The display screen is fixed to the housing, and an internal space for accommodating electronic components such as circuit boards is defined between the display screen and the housing. Interactive electronic devices generally also include an interactive module for enabling the device to interact with external objects. The interactive module includes some structural parts that need to be exposed to the outside of the electronic device. During assembly, these structural parts can be installed on the housing in sequence. For example, the structural parts can be a filter, a light guide, and a power button, etc., wherein the filter allows infrared light to pass through for remote control, the light guide collects external ambient light into the electronic device, and the power button is used to start and stop the electronic device. During installation, assemble the filter, light guide, and power button in sequence to the lower right corner of the housing.

[0004] However, when the plurality of exposed structural components are assembled on the housing respectively, the assembly process is relatively complicated, resulting in low production efficiency. Summary of the Invention

[0005] The present invention provides a display device, which can simplify the assembly process and improve production efficiency.

[0006] The present invention provides a display device, including a display panel and a shell for fixing the display panel, the shell including a front shell, the display device including an interactive unit, the interactive unit including a filter and a first structural member, the first structural member being arranged on the filter. During assembly, it is only necessary to assemble the filter and the front shell, without having to assemble the filter and the first structural member to the front shell one by one as in the prior art, thereby simplifying the assembly process of the filter, the first structural member and the shell.

[0007] Furthermore, the first structural members exposed outside the display device are integrated on the filter element, so that the appearance of the display device does not have an obviously visible filter element, making the appearance of the display device more simple and beautiful.

[0008] In some embodiments of the present application, the filter element includes a mounting portion located within the accommodating chamber, and a protruding portion exposed to the outside through an opening. When the protruding portion is located in the opening, the mounting portion is blocked on the inner side of the front shell to serve as a limit to prevent the filter element from detaching from the front shell.

[0009] In some embodiments of the present application, the outer contour of the protrusion matches the opening edge of the opening, so that the side surface of the protrusion is in close contact with the opening edge of the opening, to prevent a gap between the protrusion and the opening, so that dust and the like enters the inside of the display device.

[0010] In some embodiments of the present application, the through-avoidance hole is arranged on the protrusion, so that when the number of the first structural members is multiple, the first structural members are all concentrated in the range of the light filtering member, so that the exposed parts of the first structural members are more concentrated, and the appearance is more beautiful.

[0011] In some embodiments of the present application, the opening is located at the side of the side end of the display screen. Therefore, the light filtering member and the first structural member arranged through the opening are not located at the front side of the display screen, so that the thickness of the display device is not increased.

[0012] In some embodiments of the present application, the number of the first structural members is multiple, the multiple first structural members include a key, the through-avoidance hole includes a key-avoidance hole, part of the structure of the key is arranged in the key-avoidance hole, and the key can move along the through direction of the key-avoidance hole.

[0013] For the case that the number of the first structural members is multiple, the multiple first structural members are integrated on the light filtering member, and then the light filtering member integrated with the first structural members is assembled on the front shell. Compared with the technical solution that each first structural member is assembled respectively, the assembly is easier and the production efficiency is higher.

[0014] In some embodiments of the present application, the multiple first structural members include a light guide member, and the light guide member is used to transmit light outside the display device to the inside of the display device. The light guide member can be used to collect light in the surrounding environment for brightness adjustment of the display panel.

[0015] In some embodiments of the present application, when light propagates in the key, a shielding member is arranged between the light guide member and the key to prevent the light in the key from leaking into the light guide member and affecting the light intensity in the light guide member.

[0016] In some embodiments of the present application, the shielding member is a plate-shaped member that extends away from the light filtering member. The structure is simple and easy to process.

[0017] In some embodiments of the present application, the first structural member includes a near field communication (NFC) module, the NFC module is located in the accommodating chamber, and is arranged opposite to the light filtering member. Since metal has a certain influence on the near field communication process of the NFC module, the light filtering member is arranged opposite to the NFC module, and the NFC module is shielded by the light filtering member to avoid interference with the communication of the NFC module.

[0018] In some embodiments of the present application, the near field communication NFC module card is buckled on the induction surface of the near field communication NFC module and the mounting portion. In this way, the distance between the near field communication NFC module and the induction element outside the light filtering piece can be minimized.

[0019] In some embodiments of the present application, the front shell includes a lower front shell, and the light filtering piece and the opening are arranged on the lower front shell to meet the general aesthetic habits and operation habits of users.

[0020] In some embodiments of the present application, the display device further includes a first circuit board fixed on the rear side of the light filtering piece, and the first circuit board is provided with a key contact and a photosensitive element; the key contact is arranged opposite to the key and is used for cooperating with the key; and the photosensitive element is arranged opposite to the light guide piece and is used for receiving the light transmitted by the light guide piece.

[0021] The structural member cooperating with the key and the light guide piece is arranged on the first circuit board, and the first circuit board is also arranged on the light filtering piece, so that the relative positions of the photosensitive element and the light guide piece, and the key and the key contact are relatively accurate.

[0022] In some embodiments of the present application, at least one of the key and the light guide piece is welded to the light filtering piece. Such a connection mode is simple and will not affect the outer surface of the light filtering piece.

[0023] In some embodiments of the present application, the lower front shell extends along the width direction of the display panel; and / or the opening is located below the display panel. The lower front shell extends along the width direction of the display panel to shield the entire lower end of the display panel.

[0024] In some embodiments of the present application, the shell further includes a rear shell, the rear shell and the front shell are arranged opposite to each other, and the rear shell, the front shell and the display panel define the accommodation space.

[0025] In some embodiments of the present application, the light filtering piece is a purple-black piece. In this way, the transmission efficiency of infrared light is relatively high.

[0026] The structure of the present application and other inventive purposes and benefits will be more obvious and easy to understand through the description of the preferred embodiments in combination with the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0050] [Display panel]

[0051] The display surface of the display panel 10 is used for displaying an image, and the display surface of the display panel 10 for displaying the image is the front side, and in the case that the display panel 10 is a liquid crystal display panel 10, the display surface of the display panel 10 is the front side of the display panel 10. Figure 1 In the embodiments of the present application, the direction perpendicular to the drawing surface and away from the drawing surface is defined as the front direction, and the direction perpendicular to the drawing surface and inward is defined as the back direction.

[0052] In the embodiments of the present application, the display panel 10 can be an organic light-emitting diode (OLED) display panel, or a liquid crystal display panel. In the embodiments of the present application, the display panel 10 is taken as a liquid crystal display panel for example, but the present application is not limited thereto.

The display device 100 can include an upper side U, a lower side D, a left side L and a right side R, wherein the upper side U and the lower side D are opposite, and the left side L and the right side R are opposite.

[0054] [Shell]

[0055] The shell 20 is used for fixing the display panel 10, and the shell 20 and the display panel 10 define a receiving chamber located inside the display device 100. Further, the backlight module, various circuit boards, sensors, batteries and other modules (not shown) included in the display device 100 can also be accommodated in the shell 20.

[0056] The backlight module includes a back plate, a middle frame and a glue frame (not shown), and the display panel 10 is fixed on the middle frame and the glue frame, the middle frame and the glue frame are fixed on the back plate, and the back plate is fixed on the shell 20, so as to finally fix the display panel 10 on the shell 20.

[0057] Figure 3 The rear view structure schematic diagram of the front shell 21 in the display device 100 provided by the embodiments of the present application is shown.

[0058] Referring to Figure 1 , Figure 3The housing 20 comprises a front shell 21, which can be a frame extending along the side ends of the display panel 10. For example, the front shell 21 comprises a left front shell 211, a right front shell 212, an upper front shell 213, and a lower front shell 214, which are connected end to end in sequence to form the frame-shaped front shell 21.

[0059] For example, the front shell 21 covers the side ends of the display panel 10, where the side ends of the display panel 10 specifically refer to the side ends perpendicular to the display surface of the display panel 10. The front shell 21 is formed with an opening 22 communicating with the accommodating chamber. Part of the front shell 21 is located in front of the display panel 10, thereby covering the edge of the display surface of the display panel 10; another part of the front shell 21 is located below the display panel 10 to cover the side end surfaces of the display panel 10.

[0060] In a possible implementation, the opening 22 is arranged on the lower front shell 214 to conform to the general aesthetic habit and operation habit of users. It can be understood that the opening 22 can be arranged on the left front shell 211, the right front shell 212, or the upper front shell 213, which is not limited in the present application.

[0061] Further, referring to Figure 1 , Figure 2 The opening 22 is located beside the side ends of the display panel, for example, the opening 22 can be located below the lower end of the display panel 10, so that when the first structural member 50 is arranged through the opening 22, the first structural member 50 is located below the display panel 10 without affecting the thickness of the display device 100.

[0062] In some embodiments of the present application, the housing 20 further comprises a rear shell (not shown), which is arranged opposite to the front shell 21, and the rear shell and the front shell 21 are opposite to each other to jointly define the accommodating chamber with the display panel 10.

[0063] [Interaction unit]

[0064] The interaction unit 40 is configured to enable the display device to interact with objects outside the display device. In the embodiments of the present application, the interaction unit 40 can comprise the light filtering member 30.

[0065] Figure 4 A structural schematic diagram of the light filtering member 30 in the display device 100 provided by the embodiments of the present application is shown in FIG. 4, Figure 5 A structural schematic diagram of the cooperation between the light filtering member 30 and the first structural member 50 in the display device 100 provided by the embodiments of the present application is shown in FIG. 5.

[0066] The filter 30 is used to filter visible light and allow infrared light for infrared remote control to pass through. Further, the interaction unit 40 further comprises an infrared receiver 41. The infrared receiver 41 is arranged inside the display device 100, for example, on the first circuit board 55 described below, and a receiving end of the infrared receiver 41 faces the filter 30. An infrared remote controller outside the display device 100 emits infrared light for infrared remote control. The infrared light is received by the infrared receiver 41 inside the display device 100 through the filter 30, so as to realize operations such as changing the working mode of the display device 100 and page turning.

[0067] With reference to Figure 2 , Figure 4 For example, the filter 30 is embedded on the front shell 21 through the opening 22. In this way, part of the filter 30 is exposed outside the display device 100, and the other part of the filter 30 is located in the accommodation chamber.

[0068] In the embodiment of the present application, with reference to Figure 4 , the filter 30 can comprise a mounting portion 31 and a protruding portion 32. The mounting portion 31 is located in the accommodation chamber and is fixed on the front shell 21. The protruding portion 32 is connected with the mounting portion 31 and protrudes from the mounting portion 31. When the protruding portion 32 is located in the opening 22, the mounting portion 31 is arranged inside the front shell 21.

[0069] In the above scheme, the filter 30 comprises the mounting portion 31 located in the accommodation chamber and the protruding portion 32 exposed outside through the opening 22. When the protruding portion 32 is located in the opening 22, the mounting portion 31 is arranged inside the front shell 21, that is, the rear surface of the front shell 21, so as to play a limiting role to prevent the filter 30 from being separated from the front shell 21.

[0070] With reference to Figure 4 , for example, the mounting portion 31 surrounds the outside of the protruding portion 32, and the outer contour of the mounting portion 31 is substantially rectangular, and the outer contour of the protruding portion 32 is long circular. Further, the mounting portion 31 comprises a mounting lug 311, and a mounting hole 312 is arranged on the mounting lug 311. When the protruding portion 32 is located in the opening 22, the mounting portion 31 is arranged inside the front shell 21, and the filter 30 is fixed on the front shell 21 by fastening the fastener through the mounting hole 312 on the mounting lug 311 and fastening with the front shell 21.

[0071] It can be understood that the fixing mode of the filter 30 and the front shell 21 is not limited to this, and other connection modes such as heat fusion, clamping, riveting and the like can also be used, and the present application does not limit this.

[0072] In the embodiment of the present application, with reference to Figure 3 , Figure 4The outer contour of the protrusion 32 matches the opening 22 edge of the opening 22, so that the side of the protrusion 32 is in contact with the opening edge of the opening 22, to prevent a gap between the protrusion 32 and the opening 22, causing dust and the like to enter the inside of the display device 100.

[0073] In the embodiments of the present application, with reference to Figure 5 The protrusion 32 is provided with a through avoiding hole 33 at a position corresponding to the first structural member 50 described below, and at least part of the first structural member 50 is exposed to the outside of the display device 100 through the through avoiding hole 33. Since the light filtering piece 30 is embedded on the front shell 21 through the opening 22, the through avoiding hole 33 provided on the protrusion 32 is in communication with the accommodation chamber inside the display device 100. In this way, part of the first structural member 50 can be located in the accommodation chamber, and the other part can be exposed to the outside of the display device 100 through the through avoiding hole 33.

[0074] Further, in the case where the number of the first structural member 50 is multiple, each first structural member 50 is concentrated in the range of the light filtering piece 30, so that the exposed part of each first structural member 50 is more concentrated, which can increase the aesthetic appearance of the display device 100.

[0075] In some embodiments of the present application, the light filtering piece 30 is a purple black piece, so that the transmission efficiency of infrared light is higher. The purple black piece refers to the appearance color of the light filtering piece 30 being purple black, so as to better filter out visible light.

[0076] The first structural member 50:

[0077] In the present application, the interactive unit 40 can also include the first structural member 50, which can refer to a structural member whose part of the structure is located inside the display device 100 and part of the structure is exposed to the outside of the display device 100, for example, can be a key 51, a light guide piece 52, etc., or can refer to a component located inside the display device 100 but arranged near the inside surface of the shell 20, for example, a near field communication NFC module 53, etc. In the present application, the first structural member 50 is arranged on the light filtering piece 30.

[0078] In this way, during assembly, only the light filtering piece 30 and the front shell 21 need to be assembled, without the need to assemble the light filtering piece 30 and the first structural member 50 one by one on the front shell 21 as in the prior art, so that the assembly process of the light filtering piece 30 and the first structural member 50 with the shell 20 becomes simple.

[0079] Further, integrating each first structural member 50 exposed to the outside of the display device 100 on the light filtering piece 30 makes the appearance of the display device 100 without the light filtering piece 30 being obviously visible, which makes the display device 100 look more simple and beautiful.

[0080] In some embodiments of the present application, the number of the first structural members 50 is multiple. For the case that the number of the first structural members 50 is multiple, the multiple first structural members 50 are integrated on the light filtering member 30, and then the light filtering member 30 integrated with the first structural members 50 is assembled on the front shell 21. Compared with the technical solution that each first structural member 50 is assembled respectively, the technical solution is more obvious in the aspects of easy assembly and high production efficiency.

[0081] Figure 6 FIG. 2 is a sectional view of the light filtering member 30 and the first structural member 50 cooperating with each other in the display device 100 provided by an embodiment of the present application, Figure 7 FIG. 3 is a rear view of the light filtering member 30 and the first structural member 50 cooperating with each other in the display device 100 provided by an embodiment of the present application.

[0082] Referring to Figure 5 The multiple first structural members 50 include the key 51. Correspondingly, the interaction unit 40 further includes a key contact 551 cooperating with the key 51. When the key 51 is pressed by an operator, the key 51 is in contact with the key contact 551, and standby, shutdown and the like of the display device are realized, so as to realize human-computer interaction.

[0083] The through avoiding hole 33 includes a key avoiding hole 511. Part of the structure of the key 51 is arranged in the key avoiding hole 511, and the key 51 can move along the action direction (the through direction of the case avoiding hole) of the key 51. The key avoiding hole 511 can be arranged on the protruding part 32.

[0084] The key 51 includes a pressing part 512 and a guide seat 513. The pressing part 512 is arranged in the guide seat 513, and can move along the pressing direction or the rebound direction of the pressing part 512 relative to the guide seat 513.

[0085] The pressing part 512 can be formed by using a light-transmissive material, and a non-light-transmissive covering layer is coated on the surface of the pressing part 512. Then, a required pattern, for example, a power pattern, is etched on the outer end surface of the pressing part 512. In the case that the key 51 has a backlight source, for example, the light source 42, the light transmitted in the pressing part 512 is emitted through the power pattern, so as to form the effect of the power-shaped light source on the case.

[0086] In the embodiment of the present application, the key 51 is welded to the light filtering member 30. Such a connection mode is simple, and does not affect the outer surface of the light filtering member 30. For example, the guide seat 513 can be welded to the inner surface of the light filtering member 30, so as to fix the key 51 on the light filtering member 30.

[0087] In some embodiments of the present application, the plurality of first structural members 50 includes a light guide member 52, which can be used to collect ambient light for brightness adjustment of the display panel 10. Specifically, the interactive unit 40 further includes a light sensing element 552 cooperating with the light guide member 52, the light guide member 52 is used to transmit light outside the display device 100 to the light sensing element 552 inside the display device 100, and the display device further includes a controller, which can control the display brightness of the display panel according to the brightness of the ambient environment detected by the light sensing element 552, so that when the light of the display panel is incident on the human eye, the human eye is comfortable.

[0088] Further, referring to Figure 6 In the case where light propagates in the key 51, the light guide member 52 and the key 51 are further provided with a shielding member 54 to prevent light in the key 51 from leaking into the light guide member 52 and affecting the light intensity in the light guide member 52.

[0089] For example, the shielding member 54 is a plate-shaped member extending away from the light filtering member 30. In this way, the shielding member 54 is simple in structure and easy to process. Of course, the structure of the shielding member 54 includes but is not limited to a plate-shaped member, and can also be a cylindrical member, which surrounds the light guide member 52, as long as it can prevent light in the key 51 from shining on the light guide member 52.

[0090] The shielding member 54 can be arranged on the light filtering member 30 or other structural members inside the display device.

[0091] In the embodiments of the present application, referring to Figure 5 , Figure 6 The light guide member avoiding hole 521 and the key avoiding hole 511 can be arranged adjacent to and spaced apart from each other to achieve better shielding effect of the shielding member 54. The hole diameter of the light guide member avoiding hole 521 and the key avoiding hole 511 can be matched with the outer contour of the light guide member 52 and the key 51 respectively. It can be understood that the hole diameter of the key avoiding hole 511 can be slightly larger than the outer contour of the pressing portion 512 of the key 51 to facilitate the pressing action of the pressing portion 512.

[0092] In the embodiments of the present application, the light guide member 52 can be welded to the light filtering member 30. For example, the light guide member 52 is welded to the inward side of the light filtering member 30 by laser heat fusion. Such a connection method is simple and will not affect the outer surface of the light filtering member 30.

[0093] In some embodiments of the present application, referring to Figure 6The display device 100 further comprises a first circuit board 55 fixed at the rear side of the light filter 30, and a key contact 551 and a light receiving element 552 are arranged on the first circuit board 55; as mentioned above, the key contact 551 is arranged opposite to the key 51 and is used to cooperate with the key 51; the light receiving element 552 is arranged opposite to the light guide 52 and is used to receive the light transmitted by the light guide 52.

[0094] The structure cooperating with the key 51 and the light guide 52 is arranged on the first circuit board 55, and the first circuit board 55 is also fixed on the light filter 30, so that the relative positions of the light receiving element 552 and the light guide 52, and the key 51 and the key contact 551 are more accurate.

[0095] Further, referring to Figure 5 The first circuit board 55 is further provided with a light source 42, which is arranged around the key contact 551, and the light source 42 is arranged opposite to the key 51, so that the light emitted by the light source 42 can enter the key 51 to make the hollow power supply pattern on the pressing part 512 emit light.

[0096] Referring to Figure 6 In a possible implementation, the interaction unit 40 can also realize the near field communication function of the display device 100.

[0097] For example, the first structure 50 comprises a near field communication NFC module 53, which is arranged in the accommodating chamber and opposite to the light filter 30, so that the light filter 30 can function as the shell of the near field communication NFC module 53. Further, the light filter 30 is arranged opposite to the mounting part 31.

[0098] Since the metal has a certain influence on the near field communication process of the near field communication NFC module 53, the light filter 30 is arranged opposite to the near field communication NFC module 53, and the near field communication NFC module 53 is shielded by the light filter 30 to avoid interfering with the communication of the near field communication NFC module 53.

[0099] In the prior art, when the near field communication NFC module 53 is arranged on the shell 20, since the shell is mostly made of metal material, in order to avoid affecting the communication of the near field communication NFC module 53, a avoiding through hole is arranged on the shell 20 at a position corresponding to the near field communication NFC module 53, and a shielding cover is arranged in the avoiding through hole to serve as a shell of the near field communication NFC module 53. In this way, in the prior art, when the near field communication NFC module 53 and the light filtering piece are arranged at the same time, two corresponding avoiding holes need to be arranged on the shell 20, while in the present application, the light filtering piece 30 is ingeniously used as the shell of the near field communication NFC module 53, the number of openings on the shell 20 is reduced, and the appearance is more beautiful.

[0100] Further, referring to Figure 6 , Figure 7 , the mounting portion 31 is provided with a clamping portion 313, and the near field communication NFC module 53 is clamped on the clamping portion 313, so that the sensing surface of the near field communication NFC module 53 is attached to the mounting portion 31. In this way, the distance between the near field communication NFC module 53 and the sensing element outside the light filtering piece 30 can be minimized.

[0101] Referring to Figure 6 and Figure 7 , the position of the near field communication NFC module 53 is closer to the light filtering piece 30 than the position of the first circuit board 55.

[0102] In the display device 100 of the present application, according to the first inventive concept, the first structural member 50 included in the interaction unit 40 is integrated on the light filtering piece 30, and then the light filtering piece 30 is assembled to the front shell 21, so that the assembly process of the light filtering piece 30 and the first structural member 50 with the shell 20 is simplified, and the production efficiency is improved. Moreover, the first structural member 50 exposed to the outside of the display device 100 is integrated on the light filtering piece 30, so that the display device 100 has no obvious light filtering piece 30 in appearance, which makes the display device 100 look more simple and beautiful.

[0103] According to the second inventive concept, the light filtering piece 30 includes the mounting portion 31 located in the accommodating chamber, so that the mounting portion 31 located in the inside of the display device 100 can also be used to fix other internal components.

[0104] According to the third inventive concept, the outer contour of the protruding portion 32 matches the opening edge of the opening 22, so that the gap between the protruding portion 32 and the front shell 21 is as small as possible, and the user is not easy to notice the boundary between the light filtering piece 30 and the front shell 21 when observing the appearance.

[0105] According to the fourth inventive concept, the through avoiding hole 33 is arranged on the protruding portion, so that the exposed parts of the first structural members 50 are distributed more concentratedly, and the appearance is more beautiful.

[0106] According to the fifth inventive concept, the opening 22 is located at the side of the side end of the display screen. In this way, when the light filter 30 is installed, it will not interfere with the display panel 10, and it is easy to assemble.

[0107] According to the sixth inventive concept, the number of the first structural members 50 is multiple. For the case that the number of the first structural members 50 is multiple, the superiority of the integrated first and then assembled second can be better embodied.

[0108] According to the seventh inventive concept, the multiple first structures include a light guide member 52. The light guide member 52 can be used to collect light in the surrounding environment for the brightness adjustment of the display panel 10.

[0109] According to the eighth inventive concept, in the case that the light propagates in the key 51, a shielding member 54 is further arranged between the light guide member 52 and the key 51, so that the measurement accuracy of the sensing element corresponding to the light guide member 52 is more accurate.

[0110] According to the ninth inventive concept, the shielding member 54 is a plate-shaped member extending from the light filter 30 to the direction away from the light filter 30. The structure is simple and easy to process.

[0111] According to the tenth inventive concept, the first structural member 50 includes a near field communication NFC module 53. The near field communication NFC module 53 is located in the accommodating chamber and is arranged opposite to the light filter 30. In this way, the near field communication NFC module 53 can be shielded by the light filter 30 to avoid interfering with the communication of the near field communication NFC module 53. In this way, the light filter 30 simultaneously plays the role of the shell of the near field communication NFC module 53 and the light filtering, and the number of parts is reduced.

[0112] According to the eleventh inventive concept, the near field communication NFC module 53 is buckled at the sensing surface of the near field communication NFC module 53 and the mounting portion 31. In this way, the distance between the near field communication NFC module 53 and the sensing member outside the light filter 30 can be minimized.

[0113] According to the twelfth inventive concept, the front shell 21 includes a lower front shell 214. The light filter 30 and the opening 22 are arranged on the lower front shell 214 to conform to the usual aesthetic habits and operation habits of the user.
