Description

  The present invention relates to a display device, and more particularly to a display device including a front cabinet and a rear cabinet that cover a display panel that displays an image.

  A liquid crystal display, which is an example of a display device, supplies power to, for example, a liquid crystal panel (cell) that displays an image, a light source (backlight), a control circuit that controls each component of the liquid crystal panel, a liquid crystal panel, and a control circuit. A power supply circuit and the like are provided.

  In recent years, in the liquid crystal display, the frame is narrowed so that the width (frame) of the front cabinet surrounding the liquid crystal panel is narrowed. The front cabinet is a member that covers the liquid crystal panel from the front side, and is a part of the casing of the liquid crystal display.

  The difference in configuration between the narrow frame liquid crystal display and the conventional liquid crystal display will be briefly described.

  FIG. 11 is an external view showing an example of the external appearance of the liquid crystal display. FIG. 12 is a cross-sectional view showing an example of the configuration of a frame portion of a liquid crystal display that is not a narrow frame. FIG. 13 is a cross-sectional view showing an example of the configuration of the frame portion of the narrow frame liquid crystal display. 12 and 13 each show a cross section of a portion corresponding to the AA 'portion of FIG. In addition, in FIGS. 11 to 13, the longitudinal direction of the liquid crystal display 100 having a rectangular shape when viewed from the front side is defined as the X axis, the lateral direction is defined as the Y axis, and the thickness direction is defined as the Z axis.

  A liquid crystal display 100 shown in FIG. 12 includes a front cabinet 101, a bezel 102, a cell 103, a cell guide 104, a rear frame 107, and the like.

  The front cabinet 101 is a member that covers the display panel (cell 103) from the front side, and is a part of the casing of the liquid crystal display 100. The front cabinet 101 forms a frame that covers the periphery of the display panel. The bezel 102 and the cell guide 104 are members that support the cell 103. The rear frame 107 is a metal member provided with a backlight, an optical sheet, a reflective sheet (not shown), and the like.

  In the liquid crystal display 100 shown in FIG. 12, the front cabinet 101 and the rear frame 107 are connected by screws 121. The screw 121 is screwed in the Z-axis direction so that the axis is parallel to the Z-axis.

  A narrow frame liquid crystal display 200 shown in FIG. 13 includes a front cabinet 201, a cell 203, a cell guide 204, a rear frame 207, a rear cabinet 208, and the like.

  The front cabinet 201 is a member that covers the display panel from the front side, and is a part of the casing of the liquid crystal display 200. The front cabinet 201 forms a frame that covers the periphery of the display panel. The cell guide 204 is a member that supports the cell 203. The rear frame 207 is a member provided with a backlight, an optical sheet, a reflection sheet (not shown), and the like. The rear cabinet 208 constitutes a part of the rear surface of the casing of the liquid crystal display 200. Note that the narrow frame liquid crystal display 200 illustrated in FIG. 13 does not include the bezel 102. Each member has a different shape, but its role is substantially the same in FIGS. 12 and 13.

  In the liquid crystal display 200 shown in FIG. 13, the front cabinet 201 and the rear frame 207 are connected by screws 122, and the rear frame 207 and the rear cabinet 208 are connected by screws 123.

  Here, in the liquid crystal display 100 shown in FIG. 12, the front cabinet and the rear frame are screwed in the Z-axis direction so that the axis of the screw 121 is parallel to the Z-axis at the frame portion. However, the frame width WF2 of FIG. 13 is significantly narrower than the frame width WF1 of the conventional liquid crystal display 100 shown in FIG. In the narrow frame liquid crystal display 200 shown in FIG. 13, since the width of the frame portion is narrow, it is not possible to secure an area for screwing in the Z-axis direction. Therefore, in the narrow frame liquid crystal display 200 shown in FIG. 13, the front cabinet 201 and the rear frame 207 are screwed in the X-axis direction so that the axis of the screw 122 is parallel to the X-axis (for example, Patent Document 1).

JP 2008-216934 A

  As described above, in recent years, the frame of a liquid crystal display has been narrowed, and a configuration without a bezel and a configuration in which a front cabinet and a rear frame are screwed in the X-axis direction may be employed.

  However, in the screwing in the Z-axis direction, as shown in FIG. 12, a force for pulling the front cabinet 101 toward the rear frame 107 in the Z-axis direction is exerted by the screw 121. On the other hand, with the screwing in the X-axis direction, as shown in FIG. 13, the force for pulling the front cabinet 201 toward the rear frame 207 does not work.

  For this reason, in the liquid crystal display 200 with a narrow frame, there is a problem that the inner peripheral end of the front cabinet 201 tends to float, that is, the interval between the front cabinet 201 and the cell 203 becomes larger than the intended interval. . Further, in the liquid crystal display 200 having a narrow frame, there is a problem that the wave of the cell 203 is likely to occur because the force for pulling the front cabinet 201 toward the rear frame 207 does not work. When the inner peripheral edge of the front cabinet 201 is floated or the cell 203 is waved, there is a problem that the design quality and the commercial value are deteriorated.

  Furthermore, such a problem may become more remarkable, for example, when the front cabinet 201 is warped or due to assembly variations. Further, in the liquid crystal display 200 that does not include the bezel 102 due to the narrow frame, the self-weight of the cell 203 is directly applied to the front cabinet 201, and therefore, the cell 203 and the front cabinet 201 tend to open easily.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a display device capable of improving design quality and commercial value in a narrow frame display device.

In order to achieve the above object, a display device according to an aspect of the present invention includes a display panel, a rear frame disposed on the back side of the display panel, a front cabinet that covers the display panel from the front side, A housing having a rear cabinet that covers the rear frame from the back side, and a first connecting member that connects the front cabinet and the rear frame inside the housing, the main axis being parallel to the display panel The first connecting member configured with a shaft body arranged to be, and the second connecting member configured with a shaft body connecting the rear frame and the rear cabinet, and the front cabinet and the rear cabinet, the end surface of one of the outer peripheral edge of the front cabinet and the rear cabinet is in contact with the other, outside of the one The end face of the end other are formed so as to press in a direction substantially perpendicular to the main surface of the display panel.

In the display device configured as described above, the end surface of one of the front and rear cabinets presses the other in the direction substantially perpendicular to the main surface of the display panel, so that the front cabinet and the rear cabinet come into contact with each other. A force is applied to the portion in the direction of separating the front cabinet and the rear cabinet . As a result, since the force that pulls the inner peripheral edge of the front cabinet toward the display panel can be applied with the first connecting member as a base point, the gap between the inner peripheral edge of the front cabinet and the display panel becomes larger than necessary. Can be prevented.

For example, before SL front cabinet, said protrusion protruding to the rear cabinet side is provided, the convex portion is the rear cabinet, may be pressed in a direction substantially perpendicular to the main surface of the display panel before SL rear cabinet, the convex portion is provided to protrude on the front cabinet side, the convex portion of the front cabinet may be pushed in a direction substantially perpendicular to the main surface of the display panel.

The display device having the above configuration is a product in which the front cabinet and the rear cabinet are assembled, and the convex portion causes the contact portion between the front cabinet and the rear cabinet to be separated from each other with the first connection member as a base point , that is, the display panel. A force can be applied in a direction substantially perpendicular to the main surface of the . Thereby, the force which draws in the inner peripheral end of a front cabinet to the display panel side can be added.

  Moreover, the said front cabinet and the said rear cabinet may each be provided with the annular fitting part which mutually fits in an outer peripheral part, and the said convex part may be provided in the perimeter of the said fitting part.

  If the convex portion is provided on the entire outer peripheral portion, it is possible to eliminate the gap or the unevenness of the gap in appearance.

  Further, each of the front cabinet and the rear cabinet may be provided with an annular fitting portion that fits to an outer peripheral portion, and the convex portion may be provided on a part of the entire circumference of the fitting portion. .

  In the case where the convex portion is provided in part, the amount of the generated material of the front cabinet or the rear cabinet can be reduced. Moreover, it becomes easy to cope with a design change.

  Furthermore, the said convex part may be provided with two or more, and the height of each said convex part may be set so that it may become so high that the position of the said convex part moves away from said 1st connection member.

  The height of the convex portion is changed according to the distance from the first connecting member, that is, according to the magnitude of the force that pulls the inner peripheral end of the front cabinet toward the display panel, so the inner peripheral end of the front cabinet is It becomes possible to make the force drawn to the display panel side more uniform.

  The housing may include a cell guide that supports the display panel, and the cell guide may include a restricting portion that restricts an inner peripheral end of the front cabinet from approaching the display panel.

  If the cell guide restricts the inner peripheral edge of the front cabinet from approaching the display panel, the inner peripheral edge of the front cabinet can be prevented from coming too close to the display panel.

  The present invention provides a display device capable of improving design quality and commercial value in a narrow frame display device.

  A liquid crystal display 10 according to the present embodiment includes a liquid crystal panel (cell), a light source (backlight), a control circuit that controls each component of the liquid crystal panel, a power supply circuit that supplies power to the liquid crystal panel, the control circuit, and the like. Etc. are provided.

[1-1. Case configuration]
The housing of the liquid crystal display 10 is composed of a plurality of members including a front cabinet 111 and a rear cabinet 18.

[1-1-1. Front cabinet]
The front cabinet 111 is a member that covers the cell 13 from the front side. In other words, the front cabinet 111 is a member constituting the frame of the cell 13.

  More specifically, the front cabinet 111 has a front surface portion f1, a side surface portion f2, a rib f3, and a screw fastening portion f4. The front cabinet 111 is a resin member in which these parts are integrally formed.

  The front part f1 is a member that constitutes the front face of the housing, and is constituted by a plate-like member having a rectangular opening. The front part f1 constitutes a frame part. The thickness of the plate member is about 2 to 3 mm. The size of the front portion f1 is a size corresponding to the size of the liquid crystal display 10, and the length of the front portion f1 in the X-axis direction (lateral direction) is determined by the number of inches of the liquid crystal display 10. It is the length in the X-axis direction + the left and right width of the frame. The length of the front portion f1 in the Y-axis direction (vertical direction) is the length of the cell 13 determined in accordance with the number of inches of the liquid crystal display 10 in the Y-axis direction + the vertical width of the frame.

  The side surface portion f2 is a member that constitutes a part of the side surface of the housing, and is configured by a plate-like member that extends from the outer peripheral end of the front surface portion f1 to the back surface side. The side surface portion f2 is provided on the entire outer peripheral end of the front surface portion f1, and is a cylindrical member. In other words, the front cabinet 111 is a bottomed cylindrical member having a rectangular bottom surface, and a rectangular opening is provided on the bottom surface. Moreover, the cross section (cross section of XZ plane in FIG. 2) of the connection part between the front part f1 and the side part f2 is shape | molded by R shape. The side surface portion f2 is in contact with the rear cabinet 18 at an end surface f5 (an example of a contact portion) at the outer peripheral end. The thickness of the side surface part f2 is about 2.5 mm. The height (length in the Z-axis direction) of the side surface part f2 is about 10 mm. The thickness of the liquid crystal display 10 is determined by the sum of the height of the side surface portion f2 and the thickness of the rear cabinet 18 described later. The size of the opening of the side surface part f2 is the same as the size of the display panel (display area of the cell 13).

  The rib f3 is a plate-like member that extends from the front surface portion f1 toward the back surface. The rib f3 is disposed inside the casing with respect to the side surface part f2. The rib f3 is provided on the entire outer periphery of the front portion f1. In other words, the rib f3 is formed of a rectangular cylindrical member whose bottom surface shape is smaller than the size of the inner periphery of the side surface portion f2 (the size inside the bottom surface), and the inner side of the side surface portion f2. Is arranged. The interval between the side surface portion f2 and the rib f3 is an interval at which a front end portion r2 of the rear cabinet 18 described later can be fitted. That is, the side wall portion f2 and the rib f3 of the front cabinet 111 and the front end portion r2 of the rear cabinet constitute a fitting portion. The thickness of the rib f3 is about 1 mm. The inner circumference of the rib f3 is larger than that of the display panel (display area of the cell 13). The size of the outer periphery of the rib f3 is smaller than the inner periphery of the side surface portion f2.

  The screw fastening portion f4 is a plate-like member in which a hole into which the screw 21 is fitted is formed, and extends further from the tip of the rib f3 to the back side. Since the screw fastening portion f4 is provided so as to extend from the rib f3, the front cabinet 111 and the rear frame 17 are connected inside the casing.

  Furthermore, as shown in FIG. 1 and FIG. 2, the front cabinet 111 of the present embodiment has a convex portion 11a on the end surface f5 of the outer peripheral end of the side surface portion f2. In other words, the front cabinet 111 of the present embodiment has the same shape and dimensions as the front cabinet 201 shown in FIG. 13 except for the convex portion 11a.

Convex portion 11a, the direction to separate the contact portion of the front cabinet 111 and the rear cabinet 18, i.e. a force in a direction substantially perpendicular to the main surface of the display panel (display region of the cell 13) Ru added. In the present embodiment, the convex portion 11a is formed of a rectangular ring having a rectangular cross section. The size of the inner periphery of the square ring is the same as the size of the inner periphery of the side surface portion f2 of the front cabinet 111. The size of the outer periphery of the square ring is smaller than the size of the outer periphery of the side surface portion f2 of the front cabinet 111. Note that the width (length in the X-axis direction) of the convex portion 11a of the present embodiment is narrower than the width of the front cabinet 111, as shown in FIGS.

  The dimension of the convex portion 11 a is determined by the size of the liquid crystal display 10. For example, when the liquid crystal display 10 is 32 inches, the thickness of the front cabinet 111 is about 10 mm, and the height of the convex portion 11a (the length in the Z-axis direction) is about 0.2 to 0.3 mm.

  The front cabinet 111 is connected to the rear frame 17 using screws 21. The screw 21 is an example of a first connecting member that connects the front cabinet 111 and the rear frame 17 inside the housing, and is arranged so that the main axis is parallel to the X-axis direction.

[1-1-2. Rear cabinet]
The rear cabinet 18 is a member that covers the cell 13 and the rear frame 17 from the back side.

  More specifically, the rear cabinet 18 has a side part r1, a tip part r2, and a back part r3. The rear cabinet 18 is a resin member in which these parts are integrally formed.

  The side surface portion r1 is formed of a cylindrical member having a rectangular bottom surface. The size of the outer periphery of the side surface portion r1 is substantially the same as the size of the outer periphery of the side surface portion f2 of the front cabinet 111. The size of the inner periphery of the side surface portion r1 is larger than the outer periphery of the rib f3 of the front cabinet 111.

  A part of the end surface of the side surface portion r1 is provided with a leading end portion r2 extending further to the front side. The tip portion r2 is thinner as it goes to the front side. The size of the inner periphery of the tip portion r2 is the same as the size of the inner periphery of the side surface portion r1. The size of the outer periphery of the tip portion r2 is smaller than the size of the outer periphery of the side surface portion r1.

  With such a configuration, a square annular end surface is formed on the side surface r1 outside the connection portion with the tip end r2. This end surface constitutes an abutting portion r4 that abuts the front cabinet 111. The thickness of the side surface portion r1 is configured such that the portion where the contact portion r4 is formed is the largest and gradually decreases toward the portion connected to the back surface portion r3. The thickness of the side surface portion is about 2.5 mm at the portion connected to the back surface portion r3.

  The back surface portion r <b> 3 is a member that covers a part of the back surface of the liquid crystal display 10. The back surface portion r3 is formed of a quadrangular frustum-shaped member. A screw fastening portion r5 through which a screw for connecting to the rear frame 17 is passed is formed on the back surface portion r3.

  The screw fastening portion r5 is a bottomed cylindrical member having a circular bottom surface, and extends from the rear portion r3 toward the rear frame 17 (is formed so as to protrude). A hole for fitting the screw 22 is formed on the bottom surface of the screw fastening portion r5. The thickness of the screwing portion r5 is the same as or smaller than the back surface portion r3.

  The screw 22 is an example of a second connecting member formed of a shaft body that connects the rear frame 17 and the rear cabinet 18, and is arranged so that the axis is parallel to the Z-axis direction.

[1-2. Internal configuration of the housing]
The liquid crystal display 10 includes a cell (display panel) 13, a cell guide 14, a rear frame 17, a rear cabinet 18, and the like in a housing.

  The configurations of the cell 13, the rear frame 17 and the rear cabinet 18 are the same as the configurations of the cell 203, the rear frame 207 and the rear cabinet 208 of the liquid crystal display 200 shown in FIG.

  The cell guide 14 is a member that supports the cell 13. The basic configuration of the cell guide 14 is the same as the cell guide 204 of FIG.

  The cell guide 14 contacts the front cabinet 111 at the end surface 14b of the one end portion 14a. In the present embodiment, the length of the one end portion 14a is shorter than the cell guide 204 (circle WB2 portion) in FIG. 13 by about 0.2 mm to 0.4 mm. This is because the force for pulling the inner peripheral edge f6 of the front cabinet 111 toward the cell 13 side works well. The end surface 14 b of the one end portion 14 a of the cell guide 14 functions as a restricting portion that restricts the inner peripheral end f 6 of the front cabinet 111 from approaching the cell 13 by contacting the front cabinet 111.

[1-3. Configuration of liquid crystal display (assembly)]
The configuration of the liquid crystal display 10 will be briefly described.

  On the rear frame 17 on which a light source (not shown) is mounted, a reflection sheet and an optical sheet (not shown), a cell 13, a cell guide 14 and the like are arranged in this order, and the front cabinet 111 is covered from the front side. Connected to the cell 13 is a COF (Chip on Film, Chip on Flexible) equipped with a drive circuit for driving the cell 13. Further, a PCB (Printed Circuit Board, printed circuit board) is connected to the COF. The front cabinet 111 and the rear frame 17 are connected by screws 21.

  Further, the rear cabinet 18 is attached to the front cabinet 111. Specifically, the front end r2 of the side surface portion r1 of the rear cabinet 18 is inserted between the side surface portion f2 and the rib f3 of the front cabinet 111 from the back side to the front side.

  The rear cabinet 18 and the rear frame 17 are connected by screws 22.

  The liquid crystal display 10 is assembled by mounting a TCON (timing controller), a power supply circuit, and the like.

[1-4. Effect etc.]
As described above, the liquid crystal display 10 according to the present embodiment has a configuration in which the front cabinet 111 is provided with the convex portion 11a on the surface that contacts the rear cabinet 208 of the front cabinet 201 shown in FIG. In addition, FIG. 14 is a figure which shows an example of a structure of the front cabinet in the comparative example in which the convex part is not provided.

  As shown in FIG. 13, the front cabinet 201 and the rear cabinet 208 are sized to fit with no gap in a state where the convex portion 11 a is not provided.

  In the present embodiment, on the other hand, a convex portion 11a is provided at a place where the front cabinet 111 and the rear cabinet 18 are fitted, and a gap is provided between the cell guide 14 and the front cabinet 111. As shown in FIG. 1, a counterclockwise force in FIG. Thereby, the edge part (inner peripheral end f6) of the opening part of the front cabinet 111 is pressed on the cell 13 side.

  Since the counterclockwise force can be made substantially constant over the entire inner peripheral end f6 of the front cabinet 111, it is possible to reduce the influence of assembling variation of each member.

  In addition, since the force which acts on the front cabinet 111 by the convex part 11a is controlled by the part which contacts the cell guide 14, it can prevent that the inner peripheral end f6 of the front cabinet 111 approaches the cell 13 too much. Further, due to the restriction by the cell guide 14, the distance between the inner peripheral edge f6 of the front cabinet 111 and the cell 13 can be made uniform.

  As a result, it is possible to more effectively prevent floating of the inner peripheral end f6 of the front cabinet 111, undulation of the cell 13, and the like.
