[Effects of the Invention]

[0007] According to the present invention, damage during impact can be suppressed. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 shows the external appearance of a display device according to an embodiment. [Figure 2] Figure 2 shows a top view of the display device. [Figure 3] Figure 3 is a cross-sectional view of the display device. [Figure 4] Figure 4 is a cross-sectional view of the display device. [Figure 5] Figure 5 is a magnified view of the bracket. [Figure 6] Figure 6 is a diagram illustrating the function and effect of the bracket. [Modes for carrying out the invention]

[0009] The embodiments of the display device disclosed herein will be described in detail below with reference to the attached drawings. However, the present invention is not limited to the embodiments described below.

[0010] First, the appearance of the display device according to the embodiment will be described using Figure 1. Figure 1 is a diagram showing the appearance of the display device according to the embodiment. The display device 1 is, for example, a display device such as a navigation system mounted in a vehicle, and is located in the center cluster, which is the central part of the front of the vehicle interior.

[0011] As shown in Figure 1, the display device 1 includes a front panel 100 which serves as a display surface for displaying information. In the example shown in Figure 1, the front panel 100 is positioned so that its upper end protrudes from the vehicle's dashboard 200.

[0012] Furthermore, the front panel 100 is configured such that the frame 2 and the display panel 3 are on the same plane. In this disclosure, the view of the front panel 100 from the front (viewed from the rear of the vehicle interior towards the front) may be referred to as a "plan view."

[0013] Frame 2 is positioned to surround and house the outside of the display panel 3 in a plan view, and functions as a bezel for the front panel 100. Frame 2 is made of, for example, a resin material.

[0014] In Figure 1, the bezel widths at the top and bottom of the frame 2 surrounding the display panel 3 are narrower than the bezel widths at the right and left edges. However, the bezel widths at the top and bottom edges may be wider than those at the right and left edges, and the bezel widths at the top, bottom, right, and left edges may all be the same.

[0015] The display panel 3 functions as the display surface of the front panel 100. A glass panel member 32 (see Figure 3) is positioned on the front portion of the display panel 3. As will be described in more detail later, the display panel 3 also includes a display element 31 (see Figure 3) and a resin member 33, etc. (see Figure 3).

[0016] Here, conventionally, when an object collides with the frame in the front panel, there was a risk that the frame would be pushed into the back side, causing the end of the glass panel member to be exposed. As a result, there was a risk that the panel member would be damaged if the object struck directly against the end of the panel member.

[0017] Therefore, in the present disclosure, the frame 2 and the display panel 3 are held by the bracket 4 (see FIG. 2) to suppress damage to the display device 1 during impact.

[0018] Hereinafter, the details of the bracket 4 will be described while referring to the drawings after FIG. 2. FIG. 2 is a top view of the display device 1. FIGS. 3 and 4 are cross-sectional views of the display device 1. In FIG. 2, a top view of the display device 1 with the frame 2 omitted is shown. Further, in FIG. 3, a cross-section when cut along the line A-A in FIG. 2 is shown, and in FIG. 4, a cross-section when cut along the line B-B in FIG. 2 is shown.

[0019] As shown in FIGS. 2 to 4, the bracket 4 extends to the outside in the plan view of the display panel 3. Further, the bracket 4 has a bent portion that bends toward the front side of the display panel 3 on the outside in the plan view of the display panel 3, and the frame 2 is disposed so as to be supported from the back side at the bent portion.

[0020] Specifically, as shown in FIG. 3, the bracket 4 extends to the upper end side of the display panel 3 and enters the frame 2 by bending toward the front side of the display panel 3 at the upper end side. That is, the bracket 4 extends to the upper end side and has a bent portion that bends toward the front side of the display panel 3 at the upper end side, and supports the upper side (the upper end side bezel) of the frame 2 from the back side.

[0021] More specifically, the end portion 21 of the frame 2 on the display panel 3 side has a shape that bends from the front side to the back side of the display panel 3. That is, the frame 2 has a substantially U-shaped cross-section with the back side recessed.

[0022] And the first end portion 41 of the bracket 4 is arranged to enter the recessed portion of the U-shaped frame 2. In other words, the first end portion 41 of the bracket 4 is arranged to sandwich the end portion 21 of the frame 2 between the display panel 3.

[0023] And the first end portion 41 of the bracket 4 and the frame 2 are arranged with a gap therebetween, and support the frame 2 when the frame 2 receives an impact. That is, the bracket 4 is arranged so as to be able to support the frame 2 during an impact.

[0024] Thereby, even when an object collides with the front side of the frame 2, the upward movement of the end portion 21 of the frame 2 is restricted by the first end portion 41 of the bracket 4, so that the frame 2 can be prevented from coming off the display device 1. The action and effect of the bracket 4 during an impact will be described in detail later in FIG. 6.

[0025] Further, the bracket 4 has a second end portion 42 (an example of a protrusion) that holds the display panel 3 from the side at the bent portion described above. Specifically, the bracket 4 holds the display panel 3 from the upper side surface which is the side surface on the upper end side of the display panel 3.

[0026] FIG. 5 is an enlarged view of the bracket 4. As shown in FIG. 5, a recess 33a is provided on the upper side surface of the display panel 3, and the bracket 4 holds the display panel 3 in a state where the tip of the second end portion 42 which is a protrusion is fitted into the recess 33a.

[0027] Here, the display panel 3 includes a display element 31, a panel member 32 that covers the display surface which is the main surface of the display element, and a resin member 33 that is disposed on the side surface of the display element 31 and provided with the recess 33a (see FIG. 3).

[0028] Furthermore, any planar display element can be used as the display element, such as liquid crystal display (LCD) elements, plasma display panel (PDP) elements, or organic light-emitting diode (OLED) elements.

[0029] In other words, the second end portion 42 of the bracket 4 holds the display panel 3 by fitting into a recess 33a provided in the resin member 33. The resin member 33 is then fixed to the back of the panel member 32 by a fixing member 34. The fixing member 34 is, for example, an adhesive member such as double-sided tape.

[0030] As a result, when an object collides with the front side of frame 2, the second end 42 of bracket 4 pulls the panel member 32 through the recess 33a of resin member 33. Consequently, the frame 2 is pushed to the rear side by the object, and at the same time, the display panel 3 is pulled to the rear side.

[0031] As a result, the front panel 100, which is composed of the display panel 3 and the frame 2, moves (deforms) to the rear side while maintaining the same plane, thus preventing misalignment between the frame 2 and the panel member 32 and avoiding exposure of the edge of the panel member 32.

[0032] In other words, damage to the end of the panel member 32 due to direct impact with an object can be prevented. These actions and effects will be described in detail later in Figure 6.

[0033] Furthermore, as shown in Figure 4, the bracket 4 is fixed from the rear to the sheet metal chassis 5 that constitutes the back of the display panel 3. Specifically, the bracket 4 is positioned on the rear side of the sheet metal chassis 5 and is fixed by fasteners 400 such as screws.

[0034] This allows the display panel 3 to be pushed not only from the second end 42 of the bracket 4 but also from the rear of the sheet metal chassis 5 when an object collides with the front side of the frame 2.

[0035] Furthermore, as shown in Figure 2, the bracket 4 holds the side of the display panel 3 at multiple points. In the example shown in Figure 2, the bracket 4 holds the upper side of the display panel 3 with four second ends 42.

[0036] This allows the load on the second end 42 during an impact to be distributed to multiple locations, thus preventing the second end 42 from being damaged and becoming non-functional due to the impact.

[0037] Furthermore, as shown in Figure 2, the bracket 4 has its first end portion 41 divided and positioned at multiple locations. In other words, the bracket 4 extends outward at multiple locations in a plan view of the display panel 3, and each of these locations bends toward the front side of the display panel 3.

[0038] This allows the load on the first end 41 during an impact to be distributed to multiple locations, thus preventing the first end 41 from being damaged and becoming non-functional due to the impact.

[0039] Next, the function and effect of bracket 4 will be explained using Figure 6. Figure 6 is a diagram illustrating the function and effect of bracket 4. Figure 6 shows an example in which object OB collides with the vicinity of the display panel 3 of frame 2 at the upper end of the front panel 100.

[0040] As shown in Figure 6, when object OB collides with the frame 2 near the display panel 3, a force is generated in the direction from front to back (arrow a) due to the collision. Consequently, an upward force (arrow b) is generated on the frame 2. In other words, a force is generated in the direction that causes the frame 2 to move away from the panel member 32.

[0041] In such a case, the bracket 4 restricts the frame 2 from moving away from the panel member 32 (in the plane of the paper). Specifically, the first end 41 of the bracket 4 restricts the end 21 of the frame 2 from moving away from the panel member 32.

[0042] As a result, frame 2 was prevented from separating from display panel 3, thus reducing the risk of damage from direct impact with object OB due to the exposed edge of panel member 32.

[0043] In particular, in a structure where the upper end of the display device 1 (front panel 100) protrudes from the dashboard 200, it is not easy to reinforce the frame 2 on the upper end side due to the need to balance aesthetics. Therefore, by using the bracket 4, damage to the display device 1 from impact can be effectively suppressed while ensuring aesthetics.

[0044] Furthermore, the collision with object OB generates a force on frame 2 in the direction from front to back (arrow a). That is, frame 2 is pushed in the direction of the back. In this case, a force is generated on bracket 4 from front to back. As a result, the second end 42 of bracket 4 pushes the recess 33a of resin member 33 in the direction from front to back (arrow c).

[0045] As a result, the panel member 32 fixed to the resin member 33 is pulled from the front to the back (arrow d). In other words, when object OB collides, as the frame 2 is pushed to the back, the display panel 3 is also pulled from the front to the back.

[0046] In other words, since the frame 2 and the display panel 3 move (deform) to the rear side while maintaining the same plane, the frame 2 separates from the display panel 3, preventing the edges of the panel member 32 from being exposed. This reduces the risk of the edges of the panel member 32 directly hitting and damaging object OB.

[0047] As described above, the display device 1 according to the embodiment comprises a display panel 3, a frame 2, and a bracket 4. The frame 2 surrounds and houses the outside of the display panel 3 in a plan view, and together with the display panel 3, constitutes the front panel 100. The bracket 4 holds the display panel 3 from the rear and extends outward in a plan view of the display panel 3. The bracket 4 has a bent portion that bends toward the front side of the display panel 3 on the outside in a plan view of the display panel 3, and is positioned so as to be able to support the frame 2 from the rear side at the bent portion, and has a projection (second end portion 42) at the bent portion that holds the display panel 3 from the side. This makes it possible to suppress damage in the event of impact.

[0048] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
