Description

TECHNICAL FIELD

[0001] The utility model relates to but are not limited to the installation equipment field of display screen, especially installation frame, display device and HUD device. BACKGROUND

[0002] Liquid crystal display screens are widely used in outdoor display devices such as billboards, mobile phones, tablet computers, notebook computers, vehicle-mounted display screens, and the like. For example, liquid crystal display screens are used in vehicle-mounted HUD devices (head-up display devices). As a vehicle-mounted HUD device, in addition to replacing the instrument, displaying various information of the instrument panel (such as speed, tire pressure, fuel consumption, speed limit, warning, and the like), it can also display information such as navigation, auxiliary driving, automatic driving, and the like that were originally displayed on the central control multimedia screen, so that the driver hardly needs to lower his head when driving, greatly improving driving safety.

[0003] A liquid crystal display screen in a flat plate shape is usually installed into a HUD device through an installation frame. In order to ensure that the liquid crystal display screen can be smoothly installed into the installation frame, a certain gap needs to be reserved between the four peripheral edges of the liquid crystal display screen and the installation frame. However, if the gap is too large, since the vehicle will produce bumps and the like during driving, it can cause the position of the liquid crystal display screen to deviate relative to the installation frame, which can in turn affect the normal display of the HUD device; if the gap is too small, it can cause installation difficulties, and can also cause the corner of the liquid crystal display screen to collide with the installation frame, which can in turn cause the corner of the liquid crystal display screen to be damaged.

[0004] In the past structure, there is a structure in which the gap between the four peripheral edges of the liquid crystal display screen and the installation frame is appropriately enlarged, and the liquid crystal display screen is adhered to the installation frame by an adhesive such as double-sided tape. However, in this structure, there is still a case in which the position of the liquid crystal display screen deviates due to bumps and the like of the vehicle. SUMMARY

If it is described as first, second, it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present embodiment, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and those skilled in the art can reasonably determine the specific meaning of the above words in the present embodiment in combination with the specific content of the technical solution.

[0038] Referring to Figures 1 to 6 , and mainly referring to Figures 1 to 4 , as the mounting frame 100 of the first embodiment, for mounting the display screen 101. As the display screen 101, typically, the display screen 101 in a rectangular shape (including a square) can be listed. In addition, as the type of display screen 101, various types of display screens such as liquid crystal display screens, OLED display screens, MicroLED, and QLED can be listed. For example, the display screen 101 can be a liquid crystal display screen used on the known vehicle HUD device 200. The liquid crystal substrate 102 of the display screen 101, for example, includes a main body part 101a used as the main display device, and an FPC board 101b (flexible circuit board) electrically connecting the main body part 101a and other electrical elements (for example, the control system of the automobile). The FPC board 101b is connected to one end of the main body part 101a in the width direction, for example. The main body part 101a is installed in the mounting frame 100 as a whole, so that the display screen 101 as a whole can be effectively protected, and the main body part 101a and other components are prevented from being bumped, etc. The main body part 101a (for example, the glass part) is generally in a rectangular shape, and the main body part 101a is installed in the mounting frame 100 in a manner that the display area is exposed at the position of the opening of the mounting frame 100. In addition, in the process of installing the display screen 101 in the mounting frame 100, it is necessary to prevent the four corner parts 102 of the display screen 101 and the mounting frame 100 from being bumped, and in the process of use, it is necessary to prevent the position of the display screen 101 from being deviated.

[0039] The outer shape of the mounting frame 100 is set in accordance with the outer shape of the display panel 101, and in the case where the display panel 101 is substantially rectangular, the mounting frame 100 is also substantially rectangular. In the following description, for the sake of convenience, the thickness direction of the mounting frame 100 will be referred to as the "first direction" (i.e., the front-rear direction in the drawing), the direction of one side of the mounting frame 100 (e.g., the long side direction) will be referred to as the "second direction" (i.e., the left-right direction in the drawing), and the direction of the other side of the mounting frame 100 (e.g., the short side direction) will be referred to as the "third direction" (i.e., the up-down direction in the drawing). Furthermore, the first direction, the second direction, and the third direction are orthogonal to one another.

[0040] Continuing to refer to Figures 1 to 4 The mounting frame 100 of the embodiment includes a first frame body 103, a second frame body 104, a first side wall portion 105, and a plurality of positioning portions 106. The first frame body 103 and the second frame body 104 face each other with a space therebetween in the front-rear direction. The first side wall portion 105 is interposed between the first frame body 103 and the second frame body 104 in the front-rear direction, and cooperates with the first frame body 103 and the second frame body 104 to form a housing space 107 for housing the display panel 101. The plurality of positioning portions 106 are distributed around the display panel 101 in the housing space 107 in such a manner as to avoid the corners 102 of the display panel 101.

[0041] Among the plurality of positioning portions 106, there are positioning portions 106 (also referred to as "first positioning portions 106a" and "second positioning portions 106b" for the sake of convenience) that are respectively located on the left and right sides of the display panel 101 in the left-right direction, and the distance (also referred to as the first distance S1 for the sake of convenience) between the first positioning portions 106a and the second positioning portions 106b in the left-right direction is greater than the length (also referred to as the first length L1 for the sake of convenience) of the display panel 101 in the left-right direction. Furthermore, among the plurality of positioning portions 106, there are positioning portions 106 (also referred to as "third positioning portions 106c" and "fourth positioning portions 106d" for the sake of convenience) that are respectively located on the up and down sides of the display panel 101 in the up-down direction, and the distance (also referred to as the second distance S2 for the sake of convenience) between the third positioning portions 106c and the fourth positioning portions 106d in the up-down direction is greater than the length (also referred to as the second length L2 for the sake of convenience) of the display panel 101 in the up-down direction.

[0042] The mounting frame 100 of the embodiment can easily mount the display panel 101 while suppressing excessive displacement of the display panel 101 in the mounting frame 100. In the mounting frame 100 of the embodiment, because the plurality of positioning portions 106 distributed in the housing space 107 further limit the range in which the display panel 101 can move in the left-right direction and the up-down direction, the positioning accuracy of the display panel 101 in the housing space 107 can be improved, and excessive displacement of the display panel 101 in the housing space 107 can be suppressed.

[0043] Further, since these positioning portions 106 avoid the corners 102 of the display 101, in other words, the gap between the corners 102 of the display 101 and the first side wall portion 105 is larger than the gap between the side surfaces of the display 101 other than the corners 102 and these positioning portions 106, even in the position where the display 101 is at the maximum offset, the corners 102 of the display 101 do not collide with the first side wall portion 105. Therefore, when the display 101 is installed, the collision of the corners 102 of the display 101 and the first side wall portion 105 can be suppressed, and thus the display 101 can be installed more easily.

[0044] For example, the first side wall portion 105 defines a substantially rectangular accommodation space 107 as a whole, and in a state where the display 101 is accommodated in the accommodation space 107 in a center-symmetrical manner, the one-sided gap between each inner side (the side facing the accommodation space 107) of the first side wall portion 105 and each side surface of the display 101 can be in a range of 0.75 mm or more and 1.25 mm or less. That is, the length in the left-right direction and the length in the up-down direction of the rectangular accommodation space 107 defined by the first side wall portion 105 are each larger than the length in the left-right direction (also referred to as the first width W1 for convenience of distinction) and the length in the up-down direction (also referred to as the second width W2 for convenience of distinction) of the display 101 by 1.50 mm or more and 2.50 mm or less.

[0045] Further, in a state where the display 101 is accommodated in the accommodation space 107 in a center-symmetrical manner, the one-sided gap between each of the first positioning portion 106a and the second positioning portion 106b and each side surface of the display 101 in the left-right direction can be in a range of 0.20 mm or more and 0.40 mm or less. That is, the distance between the first positioning portion 106a and the second positioning portion 106b in the left-right direction (i.e., the first distance S1: the closest distance) can be larger than the length in the left-right direction (i.e., the first length L1) of the display 101 by 0.40 mm or more and 0.80 mm or less.

[0046] Similarly, in a state where the display 101 is accommodated in the accommodation space 107 in a center-symmetrical manner, the one-sided gap between each of the third positioning portion 106c and the fourth positioning portion 106d and each side surface of the display 101 in the up-down direction can be in a range of 0.20 mm or more and 0.40 mm or less. That is, the distance between the third positioning portion 106c and the fourth positioning portion 106d in the up-down direction (i.e., the second distance S2: the closest distance) can be larger than the length in the up-down direction (i.e., the second length L2) of the display 101 by 0.40 mm or more and 0.80 mm or less.

[0047] The first sidewall portion 105 includes a first side portion 108 and a second side portion 109 located on both sides in the left-right direction, and the first side portion 108 and the second side portion 109 extend in the vertical direction, respectively. The first side portion 108 is adjacent to the first positioning portion 106a, and the second side portion 109 is adjacent to the second positioning portion 106b. The first sidewall portion 105 also includes a third side portion 110 and a fourth side portion 111 located on both sides in the vertical direction, and the third side portion 110 and the fourth side portion 111 extend in the left-right direction, respectively. The third side portion 110 is adjacent to the third positioning portion 106c, and the fourth side portion 111 is adjacent to the fourth positioning portion 106d. Thus, from a top view, the first sidewall portion 105 is generally formed into a ring shape surrounding the storage space 107. In addition, a notch (not marked) can be opened in one of these sides for the routing of the FPC board 101b of the display screen 101.

[0048] The first sidewall portion 105 includes a plurality of corner protection portions 112, each corner protection portion 112 being spaced apart from each corner portion 102 of the display screen 101. The gap between each corner protection portion 112 and each corner portion 102 of the display screen 101 is the same as the gap between each inner surface of the first sidewall portion 105 and each side surface of the display screen 101. When the display screen 101 is rectangular and has four corner portions 102, the first sidewall portion 105 also includes four corner protection portions 112. Each corner protection portion 112 is sequentially connected to the end of each side portion. For example, the adjacent ends of the first side portion 108 and the third side portion 110 are connected by one corner protection portion 112, and the adjacent ends of the first side portion 108 and the fourth side portion 111 are connected by another corner protection portion 112. Each corner protection portion 112 has a first protection portion 113 and a second protection portion 114. The first protection portion 113 protects the corner 102 of the display screen 101 in the left-right direction, and the second protection portion 114 protects the corner 102 of the display screen 101 in the up-down direction. For example, in the corner protection portion 112 connecting the first side portion 108 and the third side portion 110, the first protection portion 113 extends in the up-down direction and connects to the first side portion 108; the second protection portion 114 extends in the left-right direction and connects to the third side portion 110.

[0049] The first frame 103 is a generally flat component, with a rectangular first groove 115 formed in the center. The first frame 103 is used to mount the display screen 101, and the back of the display screen 101 is attached to the first frame 103 using adhesive (not shown) such as tape. More specifically, the display screen 101 is attached to the first frame 103 with its sides facing each positioning part 106. The back of the display screen 101 is adjacent to the backlight 302 (auxiliary reference). Figure 5 On the opposite side, light from the backlight 302 shines on the back of the display screen 101 through the first groove 115.

[0050] The first side wall portion 105 and the first frame 103 are integrally formed components, and the first side wall portion 105 projects from the first frame 103 in the front-rear direction around the four peripheral edges of the first frame 103. The manner in which the first side wall portion 105 and the first frame 103 are integrally formed is not particularly limited, and for example, the first side wall portion 105 and the first frame 103 can be integrally formed by press working of sheet metal. As the material for press working, a thin sheet of a metal material such as an aluminum alloy, stainless steel, mild steel, or a magnesium alloy can be used. Alternatively, the first side wall portion 105 and the first frame 103 can be integrally formed by injection molding. As the material for injection molding, a PEEK plastic material such as ABS (acrylonitrile-butadiene-styrene), PC (polycarbonate), PC / ABS alloy, or PPS (polyphenylene sulfide) can be used. Alternatively, the first side wall portion 105 and the first frame 103 can be integrally formed by machining using a machine tool such as a CNC. As the material for machining, a metal material such as an aluminum alloy, magnesium alloy, stainless steel, or titanium alloy, an engineering plastic material such as POM (polyoxymethylene) or PC (polycarbonate), or a composite material such as carbon fiber can be used.

[0051] The positioning portion 106 and the first side wall portion 105 are integrally formed components, and the positioning portion 106 projects from the inner side of the first side wall portion 105 toward the accommodation space 107. For example, among the positioning portion 106, the first positioning portion 106a and the second positioning portion 106b project toward the accommodation space 107 in the left-right direction from the side of the first side wall portion 105 that faces the accommodation space 107. More specifically, the first positioning portion 106a projects toward the accommodation space 107 from the inner side of the first side portion 108 of the first side wall portion 105, and the second positioning portion 106b projects toward the accommodation space 107 from the inner side of the second side portion 109 of the first side wall portion 105 in a manner that brings the first positioning portion 106a and the second positioning portion 106b closer to each other in the left-right direction. The third positioning portion 106c and the fourth positioning portion 106d project toward the accommodation space 107 in the up-down direction from the side of the first side wall portion 105 that faces the accommodation space 107. More specifically, the third positioning portion 106c projects toward the accommodation space 107 from the inner side of the third side portion 110 of the first side wall portion 105, and the fourth positioning portion 106d projects toward the accommodation space 107 from the inner side of the fourth side portion 111 of the first side wall portion 105 in a manner that brings the third positioning portion 106c and the fourth positioning portion 106d closer to each other in the up-down direction. Thus, a positioning space that is smaller than the display panel 101 is defined in the accommodation space 107 by the first positioning portion 106a, the second positioning portion 106b, the third positioning portion 106c, and the fourth positioning portion 106d.

[0052] Reference will be made primarily to Figure 4The first positioning portion 106a and the second positioning portion 106b each include a plurality of portions, and the plurality of first positioning portions 106a and the plurality of second positioning portions 106b are each spaced apart in the up-and-down direction. For example, the first positioning portion 106a can be formed with two portions on the first side portion 108, and the two first positioning portions 106a are spaced apart in the up-and-down direction of the first side portion 108. The distance between the two first positioning portions 106a is not particularly limited as long as the two first positioning portions 106a avoid the position of the corner protection portion 112. The second positioning portion 106b can also be formed with two portions on the second side portion 109, and the two portions are opposite to the first positioning portion 106a in the left-and-right direction.

[0053] The third positioning portion 106c and the fourth positioning portion 106d each include a plurality of portions, and the plurality of third positioning portions 106c and the plurality of fourth positioning portions 106d are each spaced apart in the left-and-right direction. For example, the third positioning portion 106c can be formed with two portions on the third side portion 110, and the two third positioning portions 106c are spaced apart in the left-and-right direction of the third side portion 110. The distance between the two third positioning portions 106c is not particularly limited as long as the two third positioning portions 106c avoid the position of the corner protection portion 112. The fourth positioning portion 106d can also be formed with two portions on the fourth side portion 111, and the two portions are opposite to the third positioning portion 106c in the left-and-right direction.

[0054] The first positioning portion 106a, the second positioning portion 106b, the third positioning portion 106c, and the fourth positioning portion 106d can have substantially the same structure, except that the positions in which the first positioning portion 106a, the second positioning portion 106b, the third positioning portion 106c, and the fourth positioning portion 106d are formed in the first side wall portion 105 are different. Therefore, when the structures of the positioning portions 106 are described, the positioning portions 106 are collectively described without being particularly distinguished unless necessary.

[0055] Mainly referring to Figure 3 The positioning portion 106 has a positioning surface 116, and the positioning surface 116 is opposite to the side surface of the display screen 101, and the positioning surface 116 is closer to the side surface of the display screen 101 than to the side of the first side wall portion 105 to which the positioning portion 106 is connected. For example, the positioning surface 116 of the first positioning portion 106a is closer to the side surface of the display screen 101 on the same side in the left-and-right direction than to the inner side surface of the first side portion 108 which is integrally formed with the first positioning portion 106a. Similarly, the positioning surface 116 of the second positioning portion 106b is also closer to the side surface of the display screen 101 on the same side in the left-and-right direction than to the inner side surface of the second side portion 109 which is integrally formed with the second positioning portion 106b. The same is true for the third positioning portion 106c and the fourth positioning portion 106d.

[0056] The distance between the positioning surface 116 and the side of the first side wall portion 105 to which the positioning surface 116 is connected (also referred to as the third distance S3 for ease of distinction) is in a range of 0.35 mm or more and 1.05 mm or less. For example, the distance between the positioning surface 116 of the fourth positioning portion 106d and the inner side surface of the fourth side portion 111 in the up-down direction is in a range of 0.35 mm or more and 1.05 mm or less. The positioning surface 116 can be, for example, a flat surface, and the positioning surface 116 and the inner side surface of the first side wall portion 105 adjacent to the positioning surface 116 are parallel.

[0057] The positioning portion 106 can also have a guide surface 117 that connects the positioning surface 116 and the side of the first side wall portion 105 to which the positioning surface 116 is connected and is inclined toward the first frame 103. For example, the guide surface 117 of the first positioning portion 106a connects the positioning surface 116 of the first positioning portion 106a and the inner side surface of the first side portion 108 and is inclined toward the first frame 103. The angle R1 of the side of the guide surface 117 toward the first frame 103 with respect to the inner side of the first side wall portion 105 to which the guide surface 117 is connected is, for example, in a range of 30° or more and 60° or less.

[0058] The guide surfaces 117 and the positioning surfaces 116 of the positioning portions 106 can be formed when the first side wall portion 105 and the first frame 103 are integrally formed. For example, when the first side wall portion 105 and the first frame 103 are integrally formed by sheet metal stamping, the first side wall portion 105 can be stamped from the outer side of the first side wall portion 105 to form the positioning portions 106 that protrude toward the accommodation space 107. In addition, in order to easily deform the positioning portions 106 and prevent a round corner between the bottom of the positioning portions 106 and the first frame 103 from interfering with the display screen 101, a notch (not shown) or the like can be formed in the blank at the position where the positioning portions 106 are formed before stamping. In addition, when formed by injection molding or machining by cutting away material, the positioning portions 106 can be machined together with the first side wall portion 105 and the first frame 103 by a conventional process.

[0059] Continuing with reference to Figure 1 and Figure 2The second frame 104 is a member that covers the first frame 103, thereby forming the housing space 107. The second frame 104 is a substantially flat member, and a rectangular second groove portion 118 is formed in a central portion of the second frame 104. The second frame 104 is used to cover the four peripheral edges of the front surface of the display panel 101, and the display surface of the display panel 101 is exposed from the second groove portion 118. A second side wall portion 119 is formed in the peripheral edge of the second frame 104, and the second side wall portion 119 is located outside the first side wall portion 105. That is, in the state in which the first frame 103 and the second frame 104 cover each other, the second side wall portion 119 surrounds the outside of the first side wall portion 105.

[0060] The second side wall portion 119 and the second frame 104 are formed as an integral member, and the second side wall portion 119 surrounds the peripheral edge of the second frame 104 and protrudes from the second frame 104 in the front-rear direction. The manner in which the second side wall portion 119 and the second frame 104 are formed as an integral member is not particularly limited, and for example, the second side wall portion 119 and the second frame 104 can be formed by the same molding method as the first frame 103, such as a press working method, an injection molding method, or a material-removing machining method. Alternatively, the second side wall portion 119 and the second frame 104 can be formed by a method different from the first frame 103 among these molding methods.

[0061] In the mounting frame 100 of the embodiment, since the plurality of positioning portions 106 distributed in the housing space 107 further restrict the range in which the display panel 101 can move in the left-right direction and the up-down direction, the positioning accuracy of the display panel 101 in the housing space 107 can be improved, and excessive displacement of the display panel 101 in the housing space 107 can be suppressed. Furthermore, since the positioning portions 106 avoid the corners 102 of the display panel 101, in other words, the gap between the corners 102 of the display panel 101 and the first side wall portion 105 is larger than the gap between the side surfaces of the display panel 101 other than the corners 102 and the positioning portions 106, even when the display panel 101 is positioned at the maximum displacement position, the corners 102 of the display panel 101 do not collide with the first side wall portion 105. Therefore, when the display panel 101 is mounted, the corners 102 of the display panel 101 can be prevented from colliding with the first side wall portion 105, and thus the display panel 101 can be more easily mounted.

[0062] In the mounting frame 100 of the embodiment, the first side wall portion 105 includes a plurality of corner protection portions 112, so that the corner portion 102 of the display screen 101 can be protected, and damage to the corner portion 102 of the display screen 101 can be suppressed, in the case where the display screen 101 is mounted to another device (for example, the HUD device 200). In addition, since the corner protection portions 112 have the first protection portion 113 and the second protection portion 114, the corner portion 102 can be protected from a plurality of directions in the left-right direction and the up-down direction, and damage to the corner portion 102 of the display screen 101 can be further suppressed.

[0063] In the mounting frame 100 of the embodiment, by making the first side wall portion 105 and the first frame body 103 one-piece components, the number of parts can be reduced, the mounting frame 100 can be prevented from being bulky, and the assembly difficulty can be reduced. In addition, by making the positioning portion 106 and the first side wall portion 105 one-piece components, the positioning portion 106 can be easily formed in a compact space, the number of parts can be further reduced, and the mounting frame 100 can be further prevented from being bulky.

[0064] In the mounting frame 100 of the embodiment, by making the positioning portions 106 protrude from the first side wall portion 105 toward the accommodation space 107, and by making the positioning portions 106 have the positioning surface 116 and the guide surface 117, the display screen 101 can be positioned with higher accuracy, and excessive positional displacement of the display screen 101 can be suppressed. In addition, by the guide surfaces 117, the display screen 101 can be more easily mounted into the accommodation space 107.

[0065] In the mounting frame 100 of the embodiment, by making the distance between the positioning surface 116 and the side of the first side wall portion 105 to which the positioning surface 116 is connected be 0.35 mm or more, the corner portion 102 of the display screen 101 and the corner protection portion 112 of the first side wall portion 105 can be prevented from colliding in the case where the display screen 101 is positioned with rotation with respect to the accommodation space 107. In addition, by making the distance be 1.05 mm or less, the entire size of the accommodation space 107 can be prevented from being excessively large, and the size of the mounting frame 100 can be prevented from being excessively large.

[0066] In addition, in the state where the display screen 101 is accommodated in the accommodation space 107 in a center-symmetrical manner, by making the gap between the positioning portion 106 (the positioning surface 116) and the side surface of the display screen 101 be in the range of 0.20 mm or more and 0.40 mm or less, the mounting accuracy of the display screen 101 can be further improved, and excessive positional displacement of the display screen 101 can be suppressed.

[0067] In the mounting frame 100 of the embodiment, the first side wall portion 105 includes a first side portion 108, a second side portion 109, a third side portion 110, and a fourth side portion 111, thereby being able to entirely surround the display screen 101 from the side, and to suppress the display screen 101 from colliding with other components during actual use.

[0068] Further, by forming the plurality of positioning portions 106 in each of the side portions, respectively, it is possible to further suppress the display screen 101 from being excessively rotated and positionally displaced with respect to the housing space 107.

[0069] In the above embodiment, although the example in which the positioning portions 106 and the first side wall portion 105 are formed as an integral component has been described, the present application is not limited thereto. For example, the positioning portions 106 and the first frame 103 are formed as an integral component, and the positioning portions 106 protrude in the front-rear direction from the surface of the first frame 103 that faces the housing space 107. Specifically, the positioning portions 106 can be positioning pins or positioning blocks that protrude in the front-rear direction from the surface of the first frame 103, and the first frame 103 is formed by injection molding, and the positioning pins or the positioning blocks are formed on the surface of the first frame 103 at the same time as the first frame 103 is injection molded.

[0070] Similarly, in this embodiment, the first side wall portion 105 can also be formed at the same time as the first frame 103 is injection molded. Further, although the positioning portions 106 protrude from the surface of the first frame 103, the circumferential direction of the positioning portions 106 can also be connected to the first side wall portion 105, thereby being able to form the first side wall portion 105 and the positioning portions 106 in a compact space, and to suppress a gap from being formed between the first side wall portion 105 and the positioning portions 106.

[0071] In the above embodiment, although the example in which the first side wall portion 105 surrounds the display screen 101 has been described, the first side wall portion 105 can be the corner protection portion 112 that protects the four corners 102 of the display screen 101, and one or all of the first side portion 108 to the fourth side portion 111 can be omitted according to the actual situation.

[0072] In the case in which the first side wall portion 105 has only the corner protection portion 112, the positioning portions 106 can be formed by protruding in the front-rear direction directly from the surface of the first frame 103.

[0073] In the above embodiment, although the example in which the first side wall portion 105 and the first frame 103 mounted on the back of the display screen 101 are integrally formed is described, the present application is not limited thereto, and the first side wall portion 105 can be integrally formed with the second frame 104 mounted on the front of the display screen 101. In this embodiment, the positioning portion 106 can be integrally formed with the first side wall portion 105 and the second frame 104, or can be integrally formed with the first frame 103. In other words, either the first side wall portion 105 or the positioning portion 106 can be independently provided on the first frame 103 or the second frame 104. Further, the first side wall portion 105 can be integrally formed with the positioning portion 106, and then provided as an independent member on the first frame 103 or the second frame 104.

[0074] Further, the connection method between the components is not particularly limited, and for example, in the example in which the positioning portion 106, the first side wall portion 105, and the first frame 103 are integrally formed, the display screen 101 can be attached to the first frame 103 by an adhesive such as glue, and the first frame 103 can be connected to the second frame 104 by various known connection methods such as adhesion, snap connection, screw connection, and the like. Similarly, in the example in which the first frame 103, the second frame 104, the first side wall portion 105, and the positioning portion 106 are independently provided or arbitrarily combined, the connection method between the components can be selected from among these various known connection methods such as adhesion, snap connection, screw connection, and the like, as needed.

[0075] In the above embodiment, although the example in which the distance between the positioning surface 116 and the side of the first side wall portion 105 to which the positioning surface 116 is connected is in the range of 0.35 mm or more and 1.05 mm or less is described, the present application is not limited thereto. For example, for the display screen 101 used in the HUD device 200 mounted on a vehicle, the range can be applied, but for other display screens 101, the range can be appropriately adjusted as needed.

[0076] Continuing with reference to Figure 5 The mounting frame 100 of the first embodiment can be used to mount the display screen 101. For example, the display device 300 according to the second embodiment includes any of the above-described mounting frames 100 and the display screen 101. The display screen 101 is housed in the housing space 107, and each side surface of the display screen 101 faces the positioning portion 106 with a gap therebetween.

[0077] Further, as such a display device 300, typically further includes a housing 301 for mounting the backlight 302, for example, one end of the housing 301 is mounted to one side of the first frame body 103 of the mounting frame 100, and the backlight 302 is mounted to the other end of the housing 301. The housing 301 serves to limit and guide the light path of the backlight 302, so that the light from the backlight 302 can efficiently irradiate to the back side of the display screen 101.

[0078] According to the display device 300 of the present embodiment, by having such a mounting frame 100 as described above, it is possible to easily mount the display screen 101 while suppressing excessive displacement of the display screen 101 within the mounting frame 100.

[0079] Continuing to refer to Figure 6 , such a display device 300 of the second embodiment can be used in a HUD device 200. For example, the HUD device 200 according to the third embodiment can have the display device 300 as described above. Further, as such a HUD device 200, typically further includes a housing 201 and an optical assembly 202. The housing 201 has a housing cavity 203 and a window portion 204 that communicates the housing cavity 203 with the outside. The display device 300 and the optical assembly 202 are respectively housed in the housing cavity 203, and the optical assembly 202 is interposed between the window portion 204 and the display device 300, so that the display information from the display surface of the display device 300 is transmitted to the outside of the housing 201 via the window portion 204.

[0080] The window portion 204 of the housing 201 faces the windshield of an automobile, and the optical assembly 202 includes, for example, a mirror 205 positioned below the window portion 204 and a lens 206, for example, interposed between the mirror 205 and the display device 300, whereby the display information of the display device 300 is transmitted to the outside of the housing 201 via the window portion 204.

[0081] According to the HUD device 200 of the present embodiment, since the display device 300 thereof has such a mounting frame 100 as described above, it is possible to easily mount the display screen 101 while suppressing excessive displacement of the display screen 101 within the mounting frame 100.

[0082] While the embodiments of the present embodiment have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made hereto without departing from the principles and spirit of the present embodiment, and the scope of the present embodiment is defined by the claims and their equivalents.
