[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-134139 Summary of the Invention [Problem to be solved by the invention]

[0005] The holding structure described in Patent Document 1 requires a protrusion to be provided on the housing of the display, resulting in a complex structure.

[0006] Furthermore, the holding structure described in Patent Document 1 includes a cover glass that covers the display surface of the display to protect the display. This holding structure fixes the cover glass to the frame, and causes the protruding portion of the display to protrude outside the portion of the frame where the cover glass is fixed, and furthermore, the tip of the protruding portion is held down by a holding portion. As such, the holding structure described in Patent Document 1 is complex in structure.

[0007] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a display device and a display holding structure that can prevent the display device from falling off with a simple configuration. [Means for solving the problem]

[0008] To achieve the above object, the display holding structure according to the present disclosure includes a cover glass, a frame, and at least one opposing member. The cover glass is formed larger than the front surface of the display that displays an image, covers the front surface of the display, and has a peripheral edge that protrudes beyond the front surface of the display. The frame has an outer frame portion in which the cover glass is fitted and an inner frame portion provided behind the outer frame portion in which the display is fitted. In a cross-sectional view, the inner frame portion protrudes from the rear surface of the outer frame portion into the internal space of the outer frame portion and then bends backward to support the peripheral edge of the cover glass and accommodate the display in the internal space. The at least one opposing member is provided on the rear surface of the display, extends to the rear end of the inner frame portion of the frame, and faces the peripheral edge of the cover glass, with the inner frame portion positioned between the peripheral edge and the frame. [Effects of the Invention]

[0009] According to the configuration of the present disclosure, the cover glass and the opposing member sandwich the display from the front and rear, and the inner frame portion of the frame is located between the cover glass and the opposing member. Therefore, the display holding structure can prevent the display from falling off in the front-to-rear direction. In addition, the configuration of the display holding structure is simple.

[0011] A display device holding structure and a display device according to an embodiment of the present disclosure will be described in detail below with reference to the drawings. In the drawings, identical or equivalent parts are designated by the same reference numerals. In the Cartesian coordinate system XYZ shown in the drawings, when the longitudinal direction of the display surface of the display device is oriented left-right and the lateral direction is oriented up-down, left-right, the left-right direction is the X-axis, the up-down direction is the Z-axis, and the direction perpendicular to the X-axis and Z-axis is the Y-axis. This coordinate system will be referenced as appropriate below.

[0012] The display device holding structure according to the embodiment is a holding structure for holding a display device incorporated in a control panel. First, with reference to Figures 1 and 2, the configuration of a display device including the display device to be held and the display device and the holding structure will be described. In the following description, an electronic device that is a combination of a display and a holding structure in which the display is incorporated will be referred to as a display device.

[0013] Fig. 1 is a front view of a display device 1 according to an embodiment and a control panel 2 incorporating the display device 1. Fig. 2 is a perspective view of the display device 1 and a front panel 21 of the control panel 2 to which the display device 1 is attached.

[0014] As shown in Fig. 1, the display device 1 is incorporated into a control panel 2. More specifically, the control panel 2 has a housing 20. The housing 20 houses various components for controlling the devices and equipment that are the targets of control by the control panel 2. The display device 1 is incorporated into the control panel 2 in order to display the operating state of the control panel 2 or to operate the control panel 2.

[0015] The above-mentioned housing 20 is formed in the shape of a rectangular parallelepiped. As a result, the housing 20 has a front panel 21, a right side panel 22, a left side panel 23, a rear panel, a top panel 24, and a bottom panel 25. Of these panels, the front panel 21 is attached to the right side panel 22 in an openable and closable manner to facilitate maintenance. As shown in FIG. 2, the front panel 21 has a rectangular opening 27 formed therein. The display device 1 is attached to the front panel 21 configured as described above by fitting it into the opening 27. This allows the user to view the display device 1 from the front of the control panel 2. Furthermore, the control panel 2 can be operated by the user from the front.

[0016] The display device 1 is equipped with a touch panel, which may come into contact with not only the user's fingers but also other objects during operation. The display device 1 is equipped with a cover glass to protect itself from such an environment. Furthermore, the display device 1 is equipped with a frame for mounting to the control panel 2. Next, the detailed configuration of the display device 1 will be described with reference to FIGS. 3 to 5.

[0017] Fig. 3 is an exploded perspective view of the display device 1. Fig. 4 is a front view of the display device 1. Fig. 5 is a cross-sectional view taken along the VV cutting line shown in Fig. 4.

[0018] As shown in Figures 3 and 4, the display device 1 includes a display 3 that displays an image, a cover glass 4 that covers the display 3 from the front, a frame 5 that houses the display 3 and the cover glass 4, and a plurality of opposing members 6 that are provided behind the display 3 and face the cover glass 4.

[0019] As shown in FIG. 5, the display device 3 has a liquid crystal panel 31 that displays images, and a touch panel 32 attached to the liquid crystal panel 31.

[0020] The liquid crystal panel 31 is, for example, a transmissive liquid crystal panel driven by a TFT (Thin Film Transistor). Although not shown, a backlight having LEDs (Light Emitting Diodes) is provided on the rear, i.e., -Y side, of the liquid crystal panel 31. The liquid crystal panel 31 also has a plurality of pixels, each having a TFT, arranged in a matrix. In the liquid crystal panel 31, each TFT is driven by a drive circuit based on an image signal, thereby adjusting the light transmittance of each pixel. In this way, the liquid crystal panel 31 adjusts the intensity of light emitted by the backlight to generate display light containing an image. A touch panel 32 is provided on the front, i.e., +Y side, of the liquid crystal panel 31 to enable operation of the control panel 2 related to the image displayed by the display light.

[0021] The touch panel 32 is a device that detects the touch position of a user's finger when the user touches it with the fingertip. For example, a capacitance-type touch panel is used for the touch panel 32. The touch panel 32 has a conductive film and detects the position of the user's fingertip based on changes in capacitance between the conductive film and the user's fingertip. The touch panel 32 outputs the detected position information. A controller (not shown) then identifies the user's operation from the position information. In this way, the touch panel 32 enables the user to operate the control panel 2.

[0022] As described above, the user's fingertip touches the touch panel 32 for operation. The location where the fingertip touches is the front surface of the touch panel 32, i.e., the +Y surface of the touch panel 32 shown in FIG. 5. However, an object other than the user's finger may come into contact with the +Y surface of the touch panel 32. Furthermore, if the control panel 2 is installed indoors, mist of oil, water, or the like may seep in through the +Y surface of the touch panel 32. Alternatively, if the control panel 2 is installed outdoors, rainwater may seep in through the +Y surface. Therefore, a cover glass 4 is provided on the +Y side of the touch panel 32 to prevent damage to the touch panel 32.

[0023] The cover glass 4 is larger than the +Y surface of the liquid crystal panel 31 and the touch panel 32. Specifically, both the liquid crystal panel 31 and the touch panel 32 have a rectangular shape with their longitudinal sides aligned in the left-right direction, i.e., the X direction, and their lateral sides aligned in the up-down direction, i.e., the Z direction, when viewed in the Y direction. In contrast, the cover glass 4 has a rectangular plate shape with its longitudinal sides longer than those of the liquid crystal panel 31 and the touch panel 32. In the rectangular plate shape of the cover glass 4, the lateral sides are longer than those of the liquid crystal panel 31 and the touch panel 32. The cover glass 4 covers the +Y surface of the touch panel 32, i.e., the +Y surface of the display 3. Furthermore, the cover glass 4 is fixed to the display 3 with an adhesive (not shown). As a result, the cover glass 4 protects the +Y surface of the display 3.

[0024] Furthermore, as shown in FIG. 3 , the +X end portion and the -X end portion of the cover glass 4 protrude in the +X direction and the -X direction from the +X end and the -X end of the display 3, respectively. As a result, the cover glass 4 completely covers the display 3 in the X direction. Furthermore, the +Z end portion and the -Z end portion of the cover glass 4 protrude in the +Z direction and the -Z direction from the +Z end and the -Z end of the display 3, respectively. As a result, the cover glass 4 completely covers the display 3 in the Z direction as well. With this configuration, the cover glass 4 covers and protects the entire +Y surface of the display 3. The cover glass 4 is housed together with the display 3 in the frame 5.

[0025] As shown in Figures 3 and 5, the frame 5 has an outer frame portion 51 into which the cover glass 4 is fitted, an inner frame portion 52 into which the display device 3 is fitted, and a rear frame portion 53 into which multiple opposing members 6 provided on the display device 3 are engaged.

[0026] The outer frame portion 51 has a rectangular frame shape. The rectangular frame shape of the outer frame portion 51 is larger than the cover glass 4 and has a rectangular shape into which the cover glass 4 can be fitted. The depth of the outer frame portion 51 in the front-to-rear direction, i.e., the Y direction, is the same as or greater than the combined length of the thickness of the cover glass 4 and the thickness of the adhesive 7. With this configuration, the outer frame portion 51 can accommodate the cover glass 4 in its internal space. The cover glass 4 is fitted into the outer frame portion 51. An inner frame portion 52 is provided behind the outer frame portion 51 to support the rear surface of the cover glass 4 and to surround and protect the display 3. The detailed positional relationship between the inner frame portion 52 and the outer frame portion 51 is shown in FIG. 6.

[0027] Fig. 6 is an enlarged cross-sectional view of region VI shown in Fig. 5. In Fig. 6, to make it easier to understand the shapes of outer frame portion 51, inner frame portion 52, and rear frame portion 53, dotted lines are drawn at the boundary between outer frame portion 51 and inner frame portion 52 and at the boundary between inner frame portion 52 and rear frame portion 53.

[0028] The inner frame portion 52 is formed in the shape of a rectangular frame when viewed from the front, and is formed in a flange shape when viewed in cross section, as shown in Fig. 6. In more detail, the inner frame portion 52 has a crank-like bent shape when viewed in cross section. That is, the inner frame portion 52 has a shape that protrudes from the rear surface of the outer frame portion 51 toward the inside of the outer frame portion 51 and then bends backward when viewed in cross section.

[0029] Length L1 of portion P1 of inner frame portion 52 protruding from the rear surface of outer frame portion 51 toward the inside of outer frame portion 51 in a cross-sectional view is equal to or smaller than length L2 of the ends of cover glass 4, i.e., the +X end portion, -X end portion, +Z end portion, and -Z end portion of cover glass 4 protruding from the +X end, -X end, +Z end, and -Z end portion of display 3, respectively, to an extent that the +X end portion, -X end portion, +Z end portion, and -Z end portion of cover glass 4 can be placed thereon. Portion P1 of inner frame portion 52 rests on the +X end portion, -X end portion, +Z end portion, and -Z end portion of cover glass 4, i.e., the ends of cover glass 4. This allows portion P1 of inner frame portion 52 to support the rear surface of cover glass 4. Furthermore, by forming the portion P1 of the inner frame portion 52 in this shape, the inner frame portion 52 itself and the rear frame portion 53 are made smaller at each end by a length L3 than the cover glass 4, thereby miniaturizing the frame 5.

[0030] Furthermore, adhesive 7 is provided on the upper surface of portion P1 of inner frame 52. This secures the edge of the placed cover glass 4 to the upper surface of portion P1. As shown in FIG. 3 , adhesive 7 is tape-like and rectangular. Because display device 1 is installed by fitting cover glass 4 into opening 27 in the front panel of control panel 2, it is susceptible to factory mist. However, because adhesive 7 has a rectangular frame shape, adhesive 7 surrounds the periphery of cover glass 4. As a result, adhesive 7 enhances the airtightness or watertightness of display device 1, enabling control panel 2 to be cleaned. When control panel 2 is installed outdoors, rainwater may seep in through opening 27. However, because adhesive 7 is formed in a rectangular frame shape and surrounds the periphery of opening 27, rainwater can be prevented from seeping in through opening 27 even in such cases.

[0031] 6, the inner frame portion 52 has a portion P2 that bends rearward in a cross-sectional view and then extends rearward. As a result, the inner frame portion 52 has a thickness T2 in the front-to-rear direction that is smaller than the thickness T1 and is large enough to accommodate the display device 3. The display device 3 is fitted into the internal space of the inner frame portion 52. As a result, the inner frame portion 52 accommodates the display device 3. The thickness T2 of the inner frame portion 52 may be the same as the thickness T1 of the display device 3, or may be larger than the thickness T1 of the display device 3.

[0032] As shown in FIG. 3 , the portion P2 of the inner frame portion 52 described above is smaller than the outer frame portion 51. Specifically, the left-right width and the up-down height of the portion P2 are smaller than the left-right width and the up-down height of the outer frame portion 51. As described above, the opening 27 is formed in the front panel 21 of the housing 20 provided in the control panel 2. The left-right width and the up-down height of the portion P2 are either the same as the left-right width and the up-down height of the opening 27 in the front panel 21, or are small enough that the portion P2 can be fitted into the opening 27. The inner frame portion 52 and the outer frame portion 51 have such a configuration, which makes it easy to attach the frame 5 to the front panel 21.

[0033] As described above, the outer frame portion 51 and the inner frame portion 52 are configured to allow the cover glass 4 and the display device 3 to be fitted into them. The outer frame portion 51 and the inner frame portion 52 support the cover glass 4 and the display device 3 by fitting the display device 3 with the cover glass 4 attached from the front. Furthermore, the cover glass 4 is attached to the inner frame portion 52 with an adhesive 7. However, because the control panel 2 is installed outdoors and the front portion of the display device 1 is located outside the housing 20 of the control panel 2, the adhesive 7 is prone to deterioration over time. If the adhesive strength of the adhesive 7 decreases due to deterioration over time, the display device 3 with the cover glass 4 attached may fall forward from the outer frame portion 51 and the inner frame portion 52. In other words, there is a risk of the display device 3 falling off from the frame 5. To prevent the display device 3 from falling off, the frame 5 includes a rear frame portion 53 and a plurality of opposing members 6 attached to the display device 3 and engaging with the rear frame portion 53, as shown in FIG. 6 .

[0034] The rear frame portion 53 is provided at the rear end of the portion P2 of the inner frame portion 52. The rear frame portion 53 is formed in the shape of a rectangular frame that follows the outer periphery of the rear end of the portion P2 of the inner frame portion 52. As shown in FIG. 6, the width W1 of the rear frame portion 53 is smaller than the width W2 of the portion P2 of the inner frame portion 52. As a result, the inner periphery of the rear end of the portion P2 of the inner frame portion 52 has an end surface E1 that is flat and parallel to the rear surface of the display 3.

[0035] The display device 1 has two opposing members 6. The opposing members 6 are engaged with the end face E1. The opposing members 6 are shown in FIGS.

[0036] Fig. 7 is a rear view of the display device 1. Fig. 8 is a perspective view of the opposing member 6 that the display device 1 includes.

[0037] As shown in FIGS. 7 and 8, the opposing member 6 has a rectangular flat plate shape. The opposing member 6 has two end faces extending in the longitudinal direction, each of which has a constriction 61 formed thereon. The two constrictions 61 are provided to determine the position of an adhesive tape (described later) when assembling the opposing member 6. In other words, the two constrictions 61 are formed as marks for determining the position to which the adhesive tape is to be applied. As shown in FIG. 7, the two constrictions 61 are positioned inward from the inner peripheral surface of the inner frame portion 52 in rear view. The adhesive tape not shown in FIG. 7 is positioned a predetermined distance inward from the two constrictions 61. The two constrictions 61 are used as marks for determining the position of the adhesive tape in this positional relationship.

[0038] 7 and 8, the opposing member 6 has a groove 62 that is rectangular in rear view on an end surface extending in the short side direction. The groove 62 extends straight in the thickness direction of the opposing member 6.

[0039] In contrast, ribs 54 are provided on both the left and right inner peripheries of the rear frame portion 53. The ribs 54 are formed in the shape of a rectangular pillar and extend straight in the front-to-rear direction. To facilitate assembly, the length of the ribs 54 is sufficiently longer than the thickness of the opposing member 6. The ribs 54 also have a rectangular shape that can be inserted into the grooves 62 when viewed from the rear as shown in FIG. 7. The ribs 54 are disposed at fixed positions in the up-down direction on the left and right inner peripheries of the rear frame portion 53.

[0040] The two opposing members 6 described above face the end face E1 of the rear frame portion 53 with a small gap between them. Furthermore, the end faces of the two opposing members 6 also abut against the inner wall of the rear frame portion 53. In this state, the ribs 54 are fitted into the grooves 62 of the two opposing members 6, respectively. This causes each opposing member 6 to engage with the corresponding rib 54. Furthermore, the positions of the two opposing members 6 in the up-down direction on the rear frame portion 53 are determined. As a result, the positions of the two opposing members 6 relative to the rear frame portion 53 are determined, and the positions are prevented from shifting relative to the rear frame portion 53.

[0041] The two opposing members 6 may abut against the end surface E1 of the rear frame portion 53. In this case, too, the end surfaces of the two opposing members 6 may abut against the inner wall of the rear frame portion 53, or may be spaced apart from the inner wall of the rear frame portion 53 and not in contact with it. Furthermore, the two opposing members 6 may not only be engaged with and stopped by the ribs 54, but may also be fixed to the ribs 54. In this case, for example, the ribs 54 may be bonded to the grooves 62, but it is preferable that the ribs 54 are simply fitted into the grooves 62 of the opposing members 6, and that the ribs 54 are not bonded to the grooves 62. This is because stress may be applied to the opposing members 6 if the ribs 54 are bonded to the grooves 62.

[0042] Furthermore, it is desirable that the adhesive strength per unit area of ​​the adhesive tape 8 is greater than the adhesive strength per unit area of ​​the adhesive 7. By fixing the opposing member 6 to the rear surface of the display device 3 with such adhesive tape 8, the display device 3 is sandwiched between the opposing member 6 and the cover glass 4, preventing the display device 3 from falling off. As a result, in the display device 1, the display device 3 is less likely to come off forward.

[0043] The adhesive 7 and adhesive tape 8 described above are examples of the first adhesive and second adhesive in the present disclosure. The +X end portion, the -X end portion, the +Z end portion, and the -Z end portion of the cover glass 4 are examples of the peripheral portion of the cover glass 4. The front surface of the touch panel 32, i.e., the +Y surface, is an example of the front surface of the display.

[0044] As described above, in the display device 1 according to the embodiment, the frame 5 includes an outer frame portion 51 in which the cover glass 4 is fitted, and an inner frame portion 52 provided behind the outer frame portion 51 and in which the display device 3 is fitted. The inner frame portion 52, in a cross-sectional view, protrudes inward from the rear surface of the outer frame portion 51 and then bends backward, supporting the edge of the cover glass 4 and housing the display device 3 within its internal space. Two opposing members 6 are provided on the rear surface of the display device 3 and extend to the rear end of the inner frame portion 52 of the frame 5 to face the periphery of the cover glass 4. As a result, the inner frame portion 52 is positioned between the periphery and the two opposing members 6. With this configuration, the display device 1 sandwiches the display device 3 between the cover glass 4 and the opposing members 6 from the front and rear. This simplifies the structure for holding the display device 3. Furthermore, the holding structure for the display device 3 prevents the display device 3 from falling off.

[0045] Furthermore, in the display device 1, the frame 5 has a rib 54 that protrudes rearward from the rear end of the inner frame portion 52. The opposing member 6 has a groove 62, and the rib 54 fits into the groove 62 to engage with the rib 54. Therefore, in the display device 1, the structure for holding the display 3 is simple and easy to manufacture.

[0046] In the display device 1, the frame 5 is provided behind the inner frame portion 52 and includes a rear frame portion 53 that protrudes rearward from the outer periphery of the inner frame portion 52. The ribs 54 are provided on the inner wall of the rear frame portion 53. Therefore, the mechanical strength of the ribs 54 is high. In addition, the positioning accuracy of the opposing member 6 is also high.

[0047] Although the display device 1 and the display device 3 holding structure according to the embodiment of the present disclosure have been described above, the display device 3 holding structure and the display device 1 are not limited to this.

[0048] For example, in the embodiment, the display device 1 includes two facing members 6. However, the display device 1 is not limited to this. The display device 1 may include at least one facing member 6. For example, the display device 1 may include only one facing member 6 at the rear end of the inner frame portion 52 of the frame 5. More specifically, one facing member 6 may be provided at either the upper or lower edge portion of the rectangular frame of the inner frame portion 52, which are opposed to each other from above and below. Alternatively, a facing member 6 may be provided at one of the four inner corners of the rectangular frame of the inner frame portion 52. Furthermore, a facing member 6 may be provided at each of the upper and lower edge portions of the rectangular frame of the inner frame portion 52, or a facing member 6 may be provided at each of the upper and lower edge portions of the rectangular frame of the inner frame portion 52, as well as at each of the left and right edge portions. Alternatively, a facing member 6 may be provided at each of the four inner corners of the rectangular frame of the inner frame portion 52.

[0049] Furthermore, in the embodiment, each of the facing members 6 has a rectangular flat plate shape. However, the facing members 6 are not limited to this. The facing members 6 may be provided on the rear surface of the display 3, extend to the rear end of the inner frame portion 52 of the frame 5, face the peripheral edge of the cover glass 4, and be positioned between the inner frame portion 52 and the peripheral edge. Therefore, the facing members 6 may have any shape as long as this condition is met. For example, the facing members 6 may be flat plates having polygonal shapes such as triangles or pentagons. They may also be block-shaped such as rectangular parallelepipeds or cubes.

[0050] Furthermore, in the embodiment, the facing member 6 faces the end face E1 of the rear frame portion 53 with a small gap therebetween, and as a result, does not abut against the end face E1. However, the facing member 6 is not limited to this. The facing member 6 may be any member that satisfies the above-mentioned conditions, and may abut against the end face E1 of the rear frame portion 53. Also, to prevent stress from being applied, it is desirable that the facing member 6 is not fixed to the rear frame portion 53, but in some cases it may be fixed to the rear frame portion 53. For example, the facing member 6 may be fixed to the rib 54.

[0051] In the embodiment, the rib 54 has a pillar shape that is rectangular in cross section. However, the rib 54 is not limited to this. The rib 54 may be any shape that protrudes rearward from the rear end of the inner frame portion 52 of the frame 5. Therefore, the shape of the rib 54 is arbitrary as long as it satisfies this condition. For example, the rib 54 may be a polygonal pillar shape, such as a triangular pillar or a pentagonal pillar. Furthermore, the rib 54 does not have to extend long enough to be called a pillar.

[0052] Furthermore, in the embodiment, the groove 62 has a rectangular cross section, but the groove 62 is not limited to this. The groove 62 may have any shape as long as the rib 54 fits into it and fixes it. Therefore, the groove 62 may have any shape as long as it satisfies this condition. For example, if the rib 54 has a rectangular cross section, the groove 62 may have a U-shape in cross section into which the rib 54 fits.

[0053] In the embodiment, the cover glass 4 is fixed to the frame 5 with adhesive 7, and the facing member 6 is fixed to the display 3 with adhesive tape 8. However, the means for fixing the cover glass 4 and the facing member 6 is not limited to this. The cover glass 4 and the facing member 6 may be fixed to the frame 5 and the display 3 by directly applying an adhesive. Alternatively, the cover glass 4 and the facing member 6 may be fixed to the frame 5 and the display 3 with an adhesive.

[0054] An adhesive is a type of glue that adheres things together without changing state from liquid to solid. The adhesive tape 8 is a tape that includes this adhesive. Unlike the adhesive 7, which does change state, the adhesive tape 8 does not change state, and is therefore reworkable.

[0055] Furthermore, in the embodiment, the display 3 includes a touch panel 32. However, the display 3 is not limited to this. The display 3 may be any device that displays images. Therefore, the display 3 may not include the touch panel 32 and may be configured only with the liquid crystal panel 31. In this case, the entire front surface of the liquid crystal panel 31, where the polarizing plate is located, is an example of the front surface of the display as referred to in the present disclosure.
