Description

Holder structure for a display and display device

[0001] The present disclosure relates to a holder structure for a display and a display device.

[0002] Some holder structures for a display prevent the display from falling off by holding the housing of the display that displays an image.

[0003] For example, Patent Document 1 discloses a holding structure for holding a display including a housing having a rectangular shape in a front view and protrusions provided on each of two sides of the rectangular shape of the housing in the front view. The holding structure described in Patent Document 1 includes a frame having a rectangular shape in a front view, and the protrusions of the display are placed on the surface on the front side of the frame. And the holding structure further includes a pressing portion for pressing the protrusions, and the pressing portion sandwiches the protrusions of the display between it and the frame, thereby holding the display and preventing it from falling off. [[ID=I0]]

[0004] Japanese Unexamined Patent Application Publication No. 2010 - 134139

[0005] In the holding structure described in Patent Document 1, it is necessary to provide protrusions on the housing of the display, and as a result, the structure is complicated.

[0006] In addition, the holding structure described in Patent Document 1 includes a cover glass that covers the display surface of the display in order to protect the display. This holding structure fixes the cover glass to the frame, protrudes the protrusions of the display outside the portion of the frame where the cover glass is fixed, and further presses the tip of the protrusions with a pressing portion. Thus, in the holding structure described in Patent Document 1, the structure is complicated.

[0007] The present disclosure has been made to solve the above problems, and an object thereof is to provide a holder structure for a display and a display device that can prevent the display from falling off with a simple configuration.

[0008] To achieve the above objective, the display holder structure according to this disclosure comprises a cover glass, a frame, and at least one opposing member. The cover glass is formed to be larger than the front surface of the display that displays an image, covering the front surface of the display, and having a peripheral edge that extends beyond the front surface of the display. The frame has an outer frame portion into which the cover glass is fitted, and an inner frame portion provided behind the outer frame portion into which the display is fitted. In cross-sectional view, the inner frame portion has a shape that 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 to house the display in the internal space. 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 opposing member.

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

[0011] Hereinafter, the display holder structure and display device according to the embodiments of this disclosure will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals. Furthermore, in the Cartesian coordinate system XYZ shown in the drawings, when the longitudinal direction of the display surface of the display device is oriented in the left-right direction and the short direction is oriented in the up-down-left-right direction, 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. Hereafter, this coordinate system will be referenced as appropriate in the explanation.

[0012] The display holder structure according to this embodiment is a holder structure that holds a display unit incorporated into a control panel. First, with reference to Figures 1 and 2, the configuration of the display device, which consists of the display unit to be held and the holder structure, will be described. In the following description, the electronic device which is a combination of a display unit and the holder structure into which the display unit is incorporated will be referred to as a display device.

[0013] Figure 1 is a front view of the display device 1 and the control panel 2 into which the display device 1 is incorporated, according to an embodiment. Figure 2 is a perspective view of the display device 1 and the front panel 21 of the control panel 2 to which the display device 1 is mounted.

[0014] As shown in Figure 1, the display device 1 is incorporated into the control panel 2. More specifically, the control panel 2 comprises a housing 20. The housing 20 houses various components for controlling the devices and equipment controlled by the control panel 2. The display device 1 is incorporated into the control panel 2 to display the operating status of the control panel 2 or to operate the control panel 2.

[0015] Furthermore, the housing 20 described above 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 so as to be openable and closable in order to facilitate maintenance. Also, as shown in Figure 2, the front panel 21 has a rectangular opening 27. The display device 1 is attached to the front panel 21 with this configuration by being fitted into the opening 27. This makes the display device 1 visible to the user from the front of the control panel 2. It also makes it possible for the user to operate the control panel 2 from the front.

[0016] The display device 1 is equipped with a touch panel, and during operation, it may be touched not only by the user's fingers but also by other objects. To protect itself from such environments, the display device 1 is equipped with a cover glass. 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 Figures 3 to 5.

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

[0018] As shown in Figures 3 and 4, the display device 1 comprises a display unit 3 for displaying images, a cover glass 4 that covers the display unit 3 from the front, a frame 5 that houses the display unit 3 and the cover glass 4, and a plurality of opposing members 6 provided behind the display unit 3 and facing the cover glass 4.

[0019] As shown in Figure 5, the display unit 3 includes a liquid crystal panel 31 for displaying images and a touch panel 32 attached to the liquid crystal panel 31.

[0020] The liquid crystal panel 31 uses, for example, a transmissive liquid crystal panel with a TFT (Thin Film Transistor) drive system. The liquid crystal panel 31 is provided with a backlight having an LED (Light Emitting Diode) on the rear side, i.e., the -Y side (not shown). The liquid crystal panel 31 also has multiple 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 to adjust the light transmittance of each pixel. As a result, the liquid crystal panel 31 adjusts the intensity of the light emitted by the backlight to generate display light including an image. On the front side of the liquid crystal panel 31, i.e., the +Y side, a touch panel 32 is provided 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 contact position of a user's fingertip when the user touches it. For example, a capacitive touch panel is used for the touch panel 32. The touch panel 32 is equipped with a conductive film, and detects the position of the user's fingertip by the change 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 fingertips come into contact with the touch panel 32 for operation. The area where the fingertips make contact is the front surface of the touch panel 32, that is, the +Y surface of the touch panel 32 as shown in Figure 5. However, objects other than the user's fingers may come into contact with the +Y surface of the touch panel 32. Also, if the control panel 2 is installed indoors, oil, water, or other mist may seep in from the +Y surface of the touch panel 32. Alternatively, if the control panel 2 is installed outdoors, rainwater may seep in from the same +Y surface. Therefore, a cover glass 4 is placed 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 plane shape of the liquid crystal panel 31 and the touch panel 32. More specifically, both the liquid crystal panel 31 and the touch panel 32 have a rectangular shape in the Y direction, with their longitudinal direction oriented left to right, i.e., the X direction, and their transverse direction oriented up to down, i.e., the Z direction. In contrast, the cover glass 4 has a rectangular plate shape in which its longitudinal direction is larger than the longitudinal direction of the liquid crystal panel 31 and the touch panel 32. In the rectangular plate shape of the cover glass 4, its transverse direction is larger than the transverse direction of the liquid crystal panel 31 and the touch panel 32. The cover glass 4 covers the +Y plane of the touch panel 32, i.e., the +Y plane of the display unit 3. Furthermore, the cover glass 4 is fixed to the display unit 3 with an adhesive (not shown). As a result, the cover glass 4 protects the +Y plane of the display unit 3.

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

[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 unit 3 is fitted, and a rear frame portion 53 into which a plurality of opposing members 6 provided on the display unit 3 are locked.

[0026] The outer frame portion 51 has a rectangular frame shape. The rectangular 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. In addition, the depth of the outer frame portion 51 in the front-to-back 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 unit 3. The detailed positional relationship between the inner frame portion 52 and the outer frame portion 51 is shown in Figure 6.

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

[0028] The inner frame portion 52 is formed in the shape of a rectangular frame when viewed from the front, and in cross-sectional view, it is formed in the shape of a flange, as shown in Figure 6. More specifically, the inner frame portion 52 has a crank-shaped bend when viewed in cross-section. That is, the inner frame portion 52 protrudes from the rear surface of the outer frame portion 51 into the inside of the outer frame portion 51 when viewed in cross-section, and then bends backward.

[0029] The length L1 of the portion P1 of the inner frame 52 that protrudes inward from the rear surface of the outer frame 51 in a cross-sectional view is equal to or smaller than the length L2 of the protrusions of the ends of the cover glass 4, i.e., the +X end portion, -X end portion, +Z end portion, and -Z end portion of the cover glass 4, from the +X end, -X end, +Z end, and -Z end portions of the display unit 3, respectively, so that the +X end portion, -X end portion, +Z end portion, and -Z end portion of the cover glass 4 can be placed on it. The +X end portion, -X end portion, +Z end portion, and -Z end portion of the cover glass 4, i.e., the ends of the cover glass 4, are placed on the portion P1 of the inner frame 52. In this way, the portion P1 of the inner frame 52 supports the rear surface of the cover glass 4. Furthermore, by forming the inner frame portion 52 in this shape, the inner frame portion 52 itself and the rear frame portion 53 are made smaller than the cover glass 4 by a length L3 at each end, thereby miniaturizing the frame 5.

[0030] Furthermore, adhesive 7 is provided on the upper surface of portion P1 of the inner frame 52. This fixes the end of the placed cover glass 4 to the upper surface of portion P1. The adhesive 7 is tape-shaped and has a rectangular frame shape, as shown in Figure 3. The cover glass 4 is susceptible to factory mist because the display device 1 is fitted into the opening 27 of the front panel of the control panel 2. However, because the adhesive 7 has a rectangular frame shape, it surrounds the periphery of the cover glass 4. As a result, the adhesive 7 enhances the airtightness and watertightness of the display device 1. This makes it possible to clean the control panel 2. If the control panel 2 is installed outdoors, rainwater may enter through the opening 27, but because the adhesive 7 is formed in the shape of a rectangular frame and surrounds the periphery of the opening 27, it is possible to prevent rainwater from entering through the opening 27 even in such cases.

[0031] Furthermore, as shown in Figure 6, the inner frame portion 52 has a portion P2 that bends backward in a cross-sectional view and then extends backward. As a result, the inner frame portion 52 has a thickness T2 in the front-to-back direction that is smaller than the thickness T1, to the extent that the display unit 3 can be accommodated. The display unit 3 is fitted into the internal space of the inner frame portion 52. As a result, the inner frame portion 52 accommodates the display unit 3. Note that the thickness T2 of the inner frame portion 52 may be the same as the thickness T1 of the display unit 3, or it may be greater than the thickness T1 of the display unit 3.

[0032] As shown in Figure 3, portion P2 of the inner frame 52 is smaller than the outer frame 51. More specifically, the width in the left-right direction and the height in the up-down direction of portion P2 are smaller than the width in the left-right direction and the height in the up-down direction of the outer frame 51. As described above, an opening 27 is formed in the front panel 21 of the housing 20 of the control panel 2. The width in the left-right direction and the height in the up-down direction of portion P2 are the same as the width in the left-right direction and the height in the up-down direction of the opening 27 of the front panel 21, or are small enough to allow portion P2 to be fitted into the opening 27. The inner frame 52 and the outer frame 51 have this configuration, which facilitates the attachment of the frame 5 to the front panel 21.

[0033] Thus, the outer frame portion 51 and the inner frame portion 52 have a configuration that allows the cover glass 4 and the display unit 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 unit 3 when the display unit 3 with the cover glass 4 attached is fitted into them from the front. Furthermore, the cover glass 4 is attached to the inner frame portion 52 with adhesive 7. However, since the control panel 2 is installed outdoors and the front part 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 decreases due to deterioration of the adhesive 7, there is a risk that the display unit 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 that the display unit 3 may fall off the frame 5. Therefore, in order to prevent the display unit 3 from falling off, the frame 5 has a rear frame portion 53 and a plurality of opposing members 6 provided on the display unit 3 that engage with the rear frame portion 53, as shown in Figure 6.

[0034] The rear frame portion 53 is provided at the rear end of portion P2 of the inner frame portion 52 described above. The rear frame portion 53 is formed in the shape of a rectangular frame along the outer circumference of the rear end of portion P2 of the inner frame portion 52. As shown in Figure 6, the width W1 of the rear frame portion 53 is smaller than the width W2 of portion P2 of the inner frame portion 52. As a result, the inner circumference side of the rear end of portion P2 of the inner frame portion 52 has a flat end face E1 that is parallel to the rear surface of the display unit 3.

[0035] The display device 1 has two opposing members 6. These opposing members 6 are locked to the end face E1. The opposing members 6 are shown in Figures 7 and 8.

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

[0037] As shown in Figures 7 and 8, the opposing member 6 has the shape of a rectangular flat plate. The opposing member 6 has two end faces extending in the longitudinal direction, each of which has a constriction 61. The two constrictions 61 are provided to determine the position of the adhesive tape, which will be described later, when assembling the opposing member 6. In short, the two constrictions 61 are formed as markers to determine the position where the adhesive tape is applied. As shown in Figure 7, the two constrictions 61 are positioned inward from the inner circumferential surface of the inner frame portion 52 when viewed from the rear. The adhesive tape, which is not shown in Figure 7, is positioned a predetermined distance inward from these two constrictions 61. The two constrictions 61 are used as markers to determine the position of the adhesive tape in this positional relationship.

[0038] Furthermore, as shown in Figures 7 and 8, the opposing member 6 has a rectangular groove 62 formed on its end face extending in the shorter direction when viewed from the rear. The groove 62 extends straight in the thickness direction of the opposing member 6.

[0039] In contrast, ribs 54 are provided on the left inner circumference and the right inner circumference of the rear frame portion 53. The ribs 54 are formed in the shape of a rectangular prism and extend straight in the front-rear direction. The length of the ribs 54 is sufficiently longer than the thickness of the opposing member 6 in order to improve ease of assembly. The ribs 54 also have a rectangular shape that can be inserted into the groove 62 when viewed from the rear as shown in Figure 7. The ribs 54 are positioned at fixed positions in the vertical direction on the left inner circumference and the right inner circumference of the rear frame portion 53.

[0040] The two opposing members 6 described above face each other with a small gap between them and the end face E1 of the rear frame 53. Furthermore, the end faces of the two opposing members 6 also abut against the inner wall of the rear frame 53. In this state, the ribs 54 are fitted into the grooves 62 of each of the two opposing members 6. As a result, each opposing member 6 is locked into the respective rib 54. In addition, the vertical positions of the two opposing members 6 on the rear frame 53 are determined. As a result, the positions of the two opposing members 6 relative to the rear frame 53 are determined, and their positional displacement relative to the rear frame 53 is prevented.

[0041] Furthermore, the two opposing members 6 may abut against the end face E1 of the rear frame 53. In this case as well, the end faces of the two opposing members 6 may abut against the inner wall of the rear frame 53, or they may not be in contact with the inner wall of the rear frame 53. Moreover, the two opposing members 6 may not only be locked, that is, engaged and stopped by the rib 54, but may also be fixed to the rib 54. In that case, for example, the rib 54 may be bonded to the groove 62, but it is preferable that the rib 54 is simply fitted into the groove 62 of each of the opposing members 6, and the rib 54 is not bonded to the groove 62. This is because if the rib 54 is bonded to the groove 62, stress may be applied to the opposing members 6.

[0042] Furthermore, it is desirable that the adhesive tape 8 has a greater adhesive strength per unit area than the adhesive strength per unit area of ​​the adhesive 7. The opposing member 6 is fixed to the rear surface of the display unit 3 by such adhesive tape 8, thereby sandwiching the display unit 3 between itself and the cover glass 4, preventing the display unit 3 from falling off. As a result, the display unit 3 is less likely to detach forward in the display device 1.

[0043] Incidentally, the adhesive 7 and the adhesive tape 8 described above are examples of the first adhesive and the second adhesive in the present disclosure. The +X end portion, -X end portion, +Z end portion, and -Z end portion of the cover glass 4 are examples of the peripheral portion of the cover glass 4. Further, the front surface of the touch panel 32, that is, 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 has an outer frame portion 51 into which the cover glass 4 is fitted and an inner frame portion 52 provided behind the outer frame portion 51 into which the display 3 is fitted. And the inner frame portion 52 has a shape that protrudes inward from the rear surface portion of the outer frame portion 51 in a cross-sectional view and then bends backward to support the end portion of the cover glass 4 and houses the display 3 in the internal space. Further, two opposing members 6 are provided on the rear surface of the display 3 and extend to the rear end portion of the inner frame portion 52 of the frame 5 and face the peripheral portion of the cover glass 4. As a result, the inner frame portion 52 is positioned between the peripheral portion and the two opposing members 6. The display device 1 is configured such that the cover glass 4 and the opposing members 6 sandwich the display 3 from the front and rear. For this reason, the configuration of the holding structure of the display 3 is simple. Also, the holding structure of the display 3 can prevent the display 3 from falling off.

[0045] Also, in the display device 1, the frame 5 has a rib 54 that protrudes rearward from the rear end portion of the inner frame portion 52. And the opposing member 6 has a groove 62, and the rib 54 is locked to the rib 54 by fitting into the groove 62. For this reason, in the display device 1, the configuration of the holding structure of the display 3 is simple and the manufacturing is easy.

[0046] In the display device 1, the frame 5 includes a rear frame portion 53 provided behind the inner frame portion 52 and protruding rearward from the outer peripheral portion of the inner frame portion 52. And the rib 54 is provided on the inner wall of the rear frame portion 53. For this reason, the mechanical strength of the rib 54 is high. Also, the positional accuracy of the opposing member 6 is high.

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

[0048] For example, in the embodiment, the display device 1 includes two opposing members 6. However, the display device 1 is not limited thereto. The display device 1 may include at least one opposing member 6. For example, the display device 1 may include only one opposing member 6 at the rear end portion of the inner frame portion 52 of the frame 5. Specifically, one opposing member 6 may be provided on either the upper side portion or the lower side portion that faces each other above and below the square frame of the inner frame portion 52. Alternatively, the opposing member 6 may be provided at one of the four inner corner portions of the square frame of the inner frame portion 52. Also, the opposing member 6 may be provided on each of the upper side portion and the lower side portion of the square frame of the inner frame portion 52, or in addition to the upper side portion and the lower side portion of the square frame of the inner frame portion 52, the opposing member 6 may also be provided on each of the left side portion and the right side portion. Further, the opposing member 6 may be provided at each of the four inner corner portions of the square frame of the inner frame portion 52.

[0049] Also, in the embodiment, each of the opposing members 6 has the shape of a rectangular flat plate. However, the opposing member 6 is not limited thereto. The opposing member 6 is provided on the rear surface of the display 3, extends to the rear end portion of the inner frame portion 52 of the frame 5, faces the peripheral edge portion of the cover glass 4, and as long as the inner frame portion 52 is positioned between it and the peripheral edge portion. Therefore, as long as the opposing member 6 satisfies this condition, its shape is arbitrary. For example, the opposing member 6 may be a flat plate of a polygon such as a triangle or a pentagon. Also, it may have the shape of a block such as a rectangular parallelepiped or a cube.

[0050] Furthermore, in the embodiment, the opposing member 6 faces the end face E1 of the rear frame portion 53 with a slight gap, and as a result, it does not contact the end face E1. However, the opposing member 6 is not limited thereto. Since the opposing member 6 may satisfy the above-described conditions, the opposing member 6 may contact the end face E1 of the rear frame portion 53. Also, it is desirable that the opposing member 6 is not fixed to the rear frame portion 53 in order to prevent stress from being applied, but in some cases, it may be fixed to the rear frame portion 53. For example, the opposing member 6 may be fixed to the rib 54.

[0051] In this embodiment, the rib 54 is shaped like a rectangular column in cross-section. However, the rib 54 is not limited to this. The rib 54 only needs to protrude rearward from the rear end of the inner frame portion 52 of the frame 5. Therefore, as long as this condition is met, the shape of the rib 54 is arbitrary. For example, the rib 54 may be shaped like a polygonal prism such as a triangular prism or a pentagonal prism. Also, the rib 54 does not need to extend long enough to be called a column.

[0052] Furthermore, although the groove 62 is rectangular in cross-section in this embodiment, the groove 62 is not limited to this. The groove 62 only needs to be such that the rib 54 fits into it and is fixed in place. Therefore, the shape of the groove 62 is arbitrary as long as this condition is met. For example, if the rib 54 is rectangular in cross-section, the groove 62 may be U-shaped in cross-section to which the rib 54 fits.

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

[0054] Adhesive is a type of adhesive that adheres objects together without undergoing a change of state from liquid to solid. Adhesive tape 8 is a tape that contains this adhesive. Furthermore, because adhesive tape 8 does not undergo a change of state, unlike adhesive 7 which does, it is a reworkable tape.

[0055] Furthermore, in this embodiment, the display unit 3 is equipped with a touch panel 32. However, the display unit 3 is not limited to this. The display unit 3 only needs to display an image. Therefore, the display unit 3 may not be equipped with a touch panel 32 and may consist only of a liquid crystal panel 31.
