[0048] <Composition of display device>

[0049] like Figures 3 to 5 As shown, an embodiment of the present application provides a display device 100 , which may be a liquid crystal display device.

[0050] In some embodiments, the display device 100 includes a housing 120 , which covers the display device 100 to cover internal components and protect the display device 100 .

[0051] The housing 120 includes a front housing 121 and a rear housing 122 , and the rear housing 122 is embedded in the back side of the front housing 121 .

[0052] In some embodiments, the display device 100 further includes a display panel 110 , which is used to display images and is mounted on the front housing 121 .

[0053] In some embodiments, the display device 100 also includes a backlight module, which is disposed on a side of the display surface away from the display panel 110 and is configured to provide backlight lamp beads to the display panel 110. The backlight module includes an optical film group and a light board. The optical film group is located between the display panel 110 and the light board. The light board is located on the light incident side of the display panel 110 and can provide the display panel 110 with the light required for display.

[0054] In some embodiments, the display device 100 further includes a back panel 130 disposed at the rear side of the light panel and supporting a backlight module and the like.

[0055] In some embodiments, the display device 100 further includes a control component 140, the control component 140 includes a key unit 141 and a control circuit board 142, the key unit 141 and the control circuit board 142 are both disposed on the back plate 130, the key unit 141 is located in the rear shell 122, and the control circuit board 142 has an infrared receiving unit 1421

[0056] In some embodiments, the display device 100 further includes a light guide 150 , the light incident end of the light guide 150 is embedded in the front shell end surface, the front shell end surface is located on the side away from the back plate 130 , and the light guide 150 extends along the back plate 130 toward the front shell end surface.

[0057] By arranging the light guide 150 and the button unit 141 as a whole front and back, the light guide 150 is embedded in the front side of the front shell 121, and the button unit 141 is located at the rear shell 122, so that the user can quickly find the position of the button 1411 and operate it conveniently; at the same time, the light guide 150 is assembled inside the front shell 121 and does not protrude from the overall structure, that is, it does not protrude from the side wall of the front shell 121, so that the multi-screen splicing function can be realized, and the effect is better.

[0058] The structures of various parts of the display device will be described in sequence below with reference to the accompanying drawings.

[0059] <Display Panel 110>

[0060] The display device 100 is a liquid crystal display device 100 , and the display device 100 includes a display panel 110 for displaying image information such as text and images.

[0061] The display panel 110 includes a touch glass and a liquid crystal screen, which are stacked in sequence along the thickness direction of the display device 100 .

[0062] It can be understood that the display panel 110 has a sky side, a ground side, a left side, a right side, and a front side and a rear side. The left side and the right side of the display panel 110 refer to the left side and the right side of the user when the user faces the touch glass side and performs a touch operation. Correspondingly, the side of the display panel 110 facing the user is the front side, the side of the display panel 110 facing away from the user is the rear side, the upper side of the display panel 110 is the sky side, and the lower side of the display panel 110 is the ground side. In this way, the touch glass is arranged in front of the liquid crystal screen to protect the liquid crystal screen.

[0063] The display panel 110 is a main component of the display device 100, which mainly includes a liquid crystal display panel, a color filter (CF) substrate of the liquid crystal display panel, a thin film transistor (TFT) substrate (also called an array substrate) and a liquid crystal (LC) layer, and the liquid crystal layer is located between the color filter substrate and the array substrate. Among them, the thin film transistor substrate is provided with data lines and scan lines, and the liquid crystal molecules are controlled to change direction by whether the data lines and the scan lines are powered on or not, so that the light of the light source is emitted through the color filter substrate and a picture of a preset color is generated.

[0064] <Housing 120>

[0065] The housing 120 includes a rear housing 122, which is located on a side of the backlight module away from the display panel 110, that is, the rear housing 122 is arranged on the rear side of the backlight module, and the controller, electrical connection lines, etc. of the display device 100 can be arranged between the backlight module and the rear housing 122 to simplify the appearance of the display device 100. The material of the rear housing 122 can be plastic, metal, etc.

[0066] The housing 120 further includes a front housing 121 , and the front housing 121 includes an upper front housing 1214 , a left front housing 1212 , a right front housing 1213 , and a lower front housing 1215 , which are arranged around the display panel 110 .

[0067] Among them, the upper front shell 1214, the left front shell 1212, the right front shell 1213 and the lower front shell 1215 are based on the user facing the display panel 110. The left front shell 1212 is located on the left side of the display panel 110, the right front shell 1213 is located on the right side of the display panel 110, the upper front shell 1214 is located at the upper end of the display panel 110, and the lower front shell 1215 is located at the lower end of the display panel 110.

[0068] <Backlight module>

[0069] Since the liquid crystal display panel itself cannot emit light, in order for the display device 100 to display normally, the display device 100 also includes a backlight module, which includes a light board. The light board is arranged on a side of the display surface away from the display panel, and the light board is used to generate light. The light board is configured to provide backlight to the display panel.

[0070] It can be understood that the light board is to provide sufficient brightness and evenly distributed backlight for the display panel, and the display panel can modulate the backlight as needed to display different images.

[0071] In some embodiments, the light board may include a light board body and a light source. The light source may be a light-emitting diode (LED), a sub-millimeter light-emitting diode (Mini-Light Emitting Diode, Mini LED) or a micron-level light-emitting diode (Micro-Light Emitting Diode, Micro LED).

[0072] There may be multiple light sources, and the multiple light sources are arranged on a side of the light board body facing the display panel and are arranged at intervals, so that the light sources provide backlight for the display panel.

[0073] Among them, the light source can be a lamp bead or a light strip, etc., and multiple light sources can be fixed on the light board body by means of snap connection, threaded connection, etc.

[0074] <Optical Components>

[0075] The display panel 110 is located on the light-emitting side of the optical assembly, and the backlight plate is located on the light-incoming side of the optical assembly. That is, the display panel 110 , the optical assembly, and the backlight plate are stacked along the thickness direction of the display device 100 .

[0076] Depending on the type of light emitted by the light source, the optical components can be of different types. For example, when the light source emits white light, the optical components can include a reflector, a light guide plate, a brightness enhancement film, etc. The reflector is mounted on the side of the backlight body where the light source is arranged.

[0077] When the light source emits blue light, the optical component may include a diffusion film, a fluorescent film and a brightness enhancement film. The diffusion film is arranged on the front side of the light source, and the user mixes the light from multiple light sources evenly, that is, converts a point light source into a surface light source.

[0078] The fluorescent film converts the light emitted by the light source into white light, so that the color of the light emitted by the light source is not limited, and the light source can emit blue light or purple light.

[0079] The brightness enhancement film is used to increase the brightness of light. It is understandable that when the light source emits white light, the optical component may also include a diffusion film, a fluorescent film and a brightness enhancement film. This embodiment is described by taking the optical component including the diffusion film, the fluorescent film and the brightness enhancement film as an example.

[0080] In some embodiments, the display panel 110 (ie, the aforementioned liquid crystal screen) and the fluorescent film assembly may be pressed together to avoid air gaps between the display panel 110, the brightness enhancement film, the fluorescent film, and the diffusion film that allow air to circulate with the outside air.

[0081] In some embodiments, the LCD screen and the optical components can also be bonded and fixed in pairs, for example, by photosensitive adhesive (UV adhesive), foam, double-sided adhesive, etc. In other words, the display panel 110 and the optical components can be connected as a whole by bonding and fixing.

[0082] <Border>

[0083] The frame can be arranged around the circumference of the display panel 110, and the formation of the frame matches the shape of the display panel 110. For example, the display panel 110 is in the direction and the frame can be a square frame structure. On the one hand, the frame can support or assist in supporting the display panel 110. On the other hand, the outer side of the frame can serve as a decorative strip.

[0084] In some embodiments, the frame may also include a top side, a left side, a right side, and a ground side, wherein the correspondence and connection relationship between the top side, the left side, the right side, and the ground side of the frame may be consistent with the correspondence and connection relationship between the top side, the left side, the right side, and the ground side of the display panel 110, and will not be repeated here.

[0085] <Control Component 140>

[0086] The control assembly 140 includes a button unit 141 and a control circuit board 142 . Both the button unit 141 and the control circuit board 142 are disposed on the back plate 130 . The button unit 141 is located in the rear shell 122 . The control circuit board 142 has an infrared receiving unit 1421 .

[0087] It is understandable that when the key unit 141 is pressed by the operator, the display device 100 is put into standby mode, turned off, etc., so as to achieve human-computer interaction.

[0088] It should be noted that, with such a configuration, the user can quickly find the position of the key unit 141, which is convenient for operation.

[0089] Figure 6 A schematic diagram of the structure of a display device provided by an embodiment of the present application from a third viewing angle, Figure 7 A schematic structural diagram of a fourth viewing angle of a display device provided in an embodiment of the present application.

[0090] refer to Figures 3 to 7 In some optional embodiments, the button unit 141 includes a button 1411 and a button bracket 1412, the button 1411 is movably arranged on the button bracket 1412, and at least a portion of the projection of the button bracket 1412 along the direction from the rear shell 122 to the front shell 121 is located on the bearing surface;

[0091] It is understandable that the fixing method of the button 1411 and the button bracket 1412 is not limited to this, and can also be other connection methods such as heat welding, clamping, riveting, etc., and this application does not impose any restrictions on this.

[0092] In some examples, the button bracket 1412 may be a metal piece, and its material may include one or more of copper, iron, aluminum, tin, and lead.

[0093] In other examples, the button bracket 1412 may be made of plastic.

[0094] It should be noted that the specific material of the button bracket 1412 is not excessively limited in the embodiment of the present application.

[0095] Of course, during manufacturing, the button bracket 1412 can also be made of steel plate, plastic or synthetic material while ensuring strength.

[0096] The rear shell 122 has a second mounting hole. The button bracket 1412 is embedded in the second mounting hole and is disposed on the back plate 130 .

[0097] It is understandable that the design of the second mounting hole allows the button bracket 1412 to pass through the second mounting hole and be fixed on the back plate 130 .

[0098] like Figure 4 As shown, in some embodiments, the cross-section of the button bracket 1412 is step-shaped, and the button bracket 1412 includes a first wall 1412a, a second wall 1412b, a third wall 1412c and a fourth wall 1412d, wherein the first wall 1412a, the second wall 1412b, the third wall 1412c and the fourth wall 1412d are connected in sequence and are in a bent step shape.

[0099] Exemplarily, the first wall surface 1412a and the second wall surface 1412b are perpendicular to each other, the second wall surface 1412b and the third wall surface 1412c are perpendicular to each other, and the third wall surface 1412c and the fourth wall surface 1412d are perpendicular to each other.

[0100] The first wall surface 1412 a is located at the outer side of the rear shell 122 , and the button 1411 is movably disposed on the first wall surface 1412 a of the button bracket 1412 and extends toward the rear shell 122 .

[0101] In some embodiments, the first wall 1412a, the second wall 1412b, the third wall 1412c and the fourth wall 1412d are integrally formed, which can ensure that the first wall 1412a, the second wall 1412b, the third wall 1412c and the fourth wall 1412d are integrally formed and manufactured and are inseparable from each other. On the one hand, the number of parts used can be reduced, the difficulty of assembly and the requirements for assembly accuracy can be reduced, the process of welding and connecting the first wall 1412a, the second wall 1412b, the third wall 1412c and the fourth wall 1412d is omitted, and the assembly efficiency is improved.

[0102] On the other hand, the overall rigidity of the key bracket 1412 can be improved, and the possibility of looseness between the first wall 1412a, the second wall 1412b, the third wall 1412c and the fourth wall 1412d can be reduced.

[0103] In some optional embodiments, the button unit 141 is located at the light emitting end of the light guide 150 .

[0104] It can be understood that the button unit 141 extends toward the back side away from the light guide 150, so that the light guide 150 and the button unit 141 are arranged integrally front and back.

[0105] The button 1411 extends along a side away from the light guide 150 , so that the button 1411 and the light guide 150 are respectively located on two opposite sides of the bearing surface of the back plate 130 .

[0106] <Light Guide 150>

[0107] The light incident end of the light guide 150 is embedded in the front shell end surface, the front shell end surface is located on the side away from the back plate 130, and the light guide 150 extends along the back plate 130 toward the front shell end surface.

[0108] In some optional embodiments, the light emitting end of the light guide 150 extends toward the back plate 130 , and the light emitting end of the light guide 150 and the infrared receiving unit are arranged opposite to each other.

[0109] It should be noted that the light guide 150 is embedded in the front shell 121, and the button 1411 is located at the rear shell 122. The light guide 150 and the button 1411 are arranged integrally front to back. The button 1411 is located at the rear shell 122, and the user can quickly find the position of the button 1411 for easy operation.

[0110] In some embodiments, the light guide 150 may be made of glass, transparent plastic, etc., and may refract or reflect light to transmit the light emitted by the external remote control transmitting device to the control panel of the display device 100 .

[0111] In other embodiments, the light guide 150 can be made of a light-guiding material, or can be made of a light-transmitting material with an inner wall coated with a reflective layer or a scattering layer, as long as it can guide the light emitted by the external remote control transmitting device to the control panel.

[0112] Through the above-mentioned arrangement, that is, by arranging the light guide 150 and the button unit 141 as a whole front and back, the light guide 150 is embedded in the front side of the front shell 121, and the button unit 141 is located at the rear shell 122, so that the user can quickly find the position of the button 1411 and operate conveniently; at the same time, the light guide 150 is assembled inside the front shell 121, does not protrude from the structure of the whole machine, that is, does not protrude from the side wall of the front shell 121, and can realize the multi-screen splicing function with better effect.

[0113] Continue to refer Figures 3 to 7 In some optional embodiments, the light guide is embedded in the front shell 121.

[0114] The light guide 150 is located in one of the left front shell 1212 and the right front shell 1213. The specific installation position can be adjusted according to actual conditions.

[0115] One of the left front shell 1212 and the right front shell 1213 defines a first mounting hole, and the light incident end of the light guide 150 is embedded in the first mounting hole.

[0116] The following description is made by taking the light guide member 150 being located in the left front housing 1212 as an example.

[0117] In some embodiments, the front shell 121 has a front wall and a side wall connected to each other, and the side wall is arranged on the periphery of the front wall and connected to the rear shell 122;

[0118] The left front shell 1212 defines a first mounting hole 1211, and the light-incoming end of the light guide 150 is embedded in the first mounting hole 1211. The front wall can be divided into an upper front shell 1214, a left front shell 1212, a right front shell 1213, and a lower front shell 1215 according to the upper, lower, left, and right positions of the display panel 110.

[0119] It can be understood that the first mounting hole 1211 is opened in the left front shell 1212, wherein the left front shell 1212 is the side facing the user, and the end of the light guide 150 extends into the first mounting hole 1211, so as to facilitate the transmission of light outside the display device 100 to the inside of the display device 100.

[0120] like Figure 4 As shown, in some embodiments, the back plate 130 has at least one step, and the step has a bearing surface, and the bearing surface is used to bear part of the key unit 141;

[0121] The light guide 150 is located outside the bearing surface, the light input end of the light guide 150 is located outside the edge of the back plate 130, and the light output end of the light guide 150 is bent toward the side of the step toward the middle of the back plate relative to the light input end of the light guide 150.

[0122] That is to say, there is an angle between the extending direction of the light incident end of the light guide member 150 and the extending direction of the light output end of the light guide member 150 .

[0123] In order to match the installation position of the light guide 150 , wherein the light guide 150 is bent, the angle between the extension direction of the light incident end of the light guide 150 and the extension direction of the light output end of the light guide 150 may be an obtuse angle.

[0124] like Figures 3 to 7 As shown, in some optional embodiments, the shape of the first mounting hole 1211 matches the shape of the light incident end of the light guide 150 , and the light incident end of the light guide 150 is flush with the left front shell 1212 .

[0125] In some embodiments, the shape of the light incident end of the light guide 150 may be rectangular or arc-shaped. Specifically, the embodiments of the present application do not impose any additional restrictions thereto.

[0126] Exemplarily, the light incident end of the light guide 150 in the embodiment of the present application is described by taking a rectangle as an example, and accordingly, the shape of the first mounting hole 1211 is also a rectangle.

[0127] It should be noted that the light incident end of the light guide 150 can be flush with the left front shell 1212 or embedded in the first installation hole 1211 .

[0128] Specifically, the shape and size of the first mounting hole 1211 are consistent with the shape and size of the light incident end of the light guide 150. The specific size values ​​are not restricted in the embodiments of the present application and can be adjusted according to actual conditions.

[0129] Figure 8 This is an assembly diagram of a control component and a light guide member in a display device provided in an embodiment of the present application from a second viewing angle.

[0130] like Figures 3 to 8 As shown, in some optional embodiments, the light guide 150 has at least one first plug-in portion 151, the first plug-in portion 151 is located on the side of the light guide 150, and the button bracket 1412 has at least one second plug-in portion 14123, the second plug-in portion 14123 and the first plug-in portion 151 are plugged into each other, and the plug-in directions of the first plug-in portion 151 and the second plug-in portion 14123 match each other and have an angle with the length direction of the light guide 150.

[0131] It should be noted that there are two first plug-in parts 151 and two second plug-in parts 14123. The two first plug-in parts 151 are respectively located on two opposite sides of the light guide 150, and the two second plug-in parts 14123 are respectively located on two opposite sides of the button bracket 1412. The positions of the first plug-in part 151 and the second plug-in part 14123 correspond to each other, and the second plug-in part 14123 and the first plug-in part 151 are plugged into each other, so that the light guide 150 can be plugged into the button bracket 1412.

[0132] In some embodiments, the plugging directions of the first plugging portion 151 and the second plugging portion 14123 and the length direction of the light guide 150 are perpendicular to each other. Of course, other forms are also possible.

[0133] like Figures 3 to 8 As shown, in some optional embodiments, the second plug-in portion 14123 includes a protrusion extending toward the light guide member 150 and a latch connected to the side of the protrusion;

[0134] The first plug-in portion 151 has a plug-in groove, the groove opening of which faces the protrusion, and the groove wall shape of the plug-in groove matches the contour of the second plug-in portion 14123, so that the first plug-in portion 151 and the second plug-in portion 14123 are mutually engaged.

[0135] Specifically, a snap-fitting notch is provided on the slot wall of the plug-in slot, the protrusion extends into the plug-in slot, and the snap-fitting teeth are snap-fitted with the snap-fitting notch, so that the light guide 150 and the button bracket 1412 are connected.

[0136] It should be noted that, during the assembly process of the light guide member 150 and the key bracket 1412 , the problem of collision between the light guide member 150 and components on the control circuit board 142 is avoided.

[0137] It should be noted that there may be multiple latching teeth, each located on the side of the protrusion. Specifically, the number of latching teeth is not too limited in the embodiment of the present application.

[0138] The latching teeth and the latching notch match each other. When the protrusion extends into the insertion slot, the latching teeth and the latching notch are latched to connect the light guide 150 and the button bracket 1412 .

[0139] The extending direction of the latch teeth may be consistent with the length direction of the light guide 150 . Specifically, the embodiments of the present application do not impose any additional restrictions thereto.

[0140] It should be noted that by forming the protrusion and the latch tooth as an integral part, not only the connection strength between the protrusion and the latch tooth can be improved, but also a seamless connection between the protrusion and the latch tooth can be achieved, thereby reducing the risk of cracking at the connection position between the protrusion and the latch tooth.

[0141] It should be noted that, in some embodiments, the protrusion and the latch tooth are connected by an integral connection method, and in other embodiments, the protrusion and the latch tooth can also be connected by other connection methods. As long as the connection method can fix the protrusion and the latch tooth, the purpose of this embodiment can be achieved. Here, there is no limitation on the connection method between the protrusion and the latch tooth.

[0142] like Figures 3 to 8 As shown, in some optional embodiments, the button bracket 1412 has a first hook 14121 and a second hook 14122, and the first hook 14121 and the second hook 14122 are arranged opposite to each other and form a clamping space between the side wall of the button bracket 1412, and the end of the control circuit board 142 extends into the clamping space so that the control circuit board 142 is clamped on the first hook 14121 and the second hook 14122.

[0143] Specifically, a first clamping space is formed between the first clamping hook 14121 and the side wall of the button bracket 1412, and a second clamping space is formed between the second clamping hook 14122 and the side wall of the button bracket 1412. The ends on opposite sides of the control circuit board 142 extend into the first clamping space and the second clamping space respectively, so that the control circuit board 142 is clamped in the first clamping hook 14121 and the second clamping hook 14122.

[0144] It should be noted that the first hook 14121 includes a first body and a first hook portion which are connected to each other, wherein there is an angle between the extension direction of the first body and the extension direction of the first hook portion, and a first clamping space is formed between the first body, the first hook portion and the side wall of the button bracket 1412 to clamp the end of the control circuit board 142.

[0145] Correspondingly, the second hook 14122 includes a second body and a second hook portion connected to each other, wherein an angle is formed between an extension direction of the second body and an extension direction of the second hook portion, and a second clamping space is formed between the second body, the second hook portion and the side wall of the button bracket 1412 to clamp the end of the control circuit board 142.

[0146] It should be noted that the structures of the first hook 14121 and the second hook 14122 may be the same or different. Specifically, the embodiments of the present application are not limited in this regard.

[0147] In some examples, this is to improve the connection stability between the control circuit board 142 and the button bracket 1412 .

[0148] It also includes a connecting piece 160. The control circuit board 142 is provided with a first connecting hole 1423, and the button bracket 1412 is provided with a second connecting hole 14124. The connecting piece 160 passes through the first connecting hole 1423 and the second connecting hole 14124 in sequence to connect the control circuit board 142 and the button bracket 1412.

[0149] It should be noted that the connecting member 160 may be multiple or one, and the connecting member 160 can connect the control circuit board 142 and the button bracket 1412 to ensure the stability of the control circuit board 142 when it is installed on the button bracket 1412 to avoid looseness between the two.

[0150] It is understandable that, when there are multiple connectors 160 , the multiple connectors 160 can be spaced apart on the same side or different sides of the control circuit board 142 to improve the stability of the connection.

[0151] In some embodiments, the connector 160 may be a threaded fastener or other connector 160 , as long as it can ensure that the control circuit board 142 is installed on the button bracket 1412 , and there are no specific restrictions.

[0152] Of course, it should be noted that in the embodiment of the present application, considering the cost of the connector 160, the connector 160 can be a threaded fastener. Correspondingly, a first connecting hole 1423 is opened on the control circuit board 142, and the first connecting hole 1423 can be a threaded hole. The connector 160 can pass through the first connecting hole 1423 and can be tightened or loosened to adjust the fixed and disassembled states.

[0153] In addition, correspondingly, a second connecting hole 14124 is opened on the button bracket 1412, and the second connecting hole 14124 can also be a threaded hole. The connecting member 160 can pass through the first connecting hole 1423, and can be tightened or loosened to adjust the fixing and disassembly states.

[0154] Specifically, the connecting member 160 passes through the first connecting hole 1423 and the second connecting hole 14124 in sequence and is tightened, thereby fixing the control circuit board 142 to the button bracket 1412. Of course, when the control circuit board 142 needs to be removed, it is only necessary to loosen the connecting member 160 and then take the connecting member 160 out of the second connecting hole 14124 and the first connecting hole 1423 in sequence.

[0155] like Figures 3 to 8 As shown, in some optional embodiments, an indicator light 1422 is provided on the control circuit board 142 , and the light guide 150 has an opaque blocking rib 152 , which is located between the indicator light 1422 and the infrared receiving unit 1421 .

[0156] It should be noted that the retaining rib 152 can not only effectively prevent the light emitted by the indicator light 1422 from interfering with the light perception of the infrared receiving unit 1421, but also enhance the strength of the entire structure.

[0157] The display device provided in the embodiment of the present application includes: a display panel for displaying images; a shell, including a front shell and a rear shell; a backlight module, a back plate, and the front shell and the rear shell are arranged on the peripheral side of the back plate; a control component, the control component includes a key unit and a control circuit board, the key unit and the control circuit board are both arranged on the back plate, the key unit is located in the rear shell, and the control circuit board has an infrared receiving unit; a light guide, the light incident end of the light guide is embedded in the end face of the front shell, the end face of the front shell is located on the side away from the back plate, and the light guide extends along the back plate toward the end face of the front shell.

[0158] By arranging the light guide and the key unit in an integrated manner front to back, the light guide is embedded in the front side of the front shell, and the key unit is located in the rear shell, so that the user can quickly find the key position and operate it conveniently; at the same time, the light guide is assembled inside the front shell, does not protrude from the overall structure of the machine, can reduce the width of the entire machine, does not protrude from the side wall of the front shell, and can realize the multi-screen splicing function with better effect.
