[0001] Cross-references to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0166815, filed on December 2, 2020, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a display device and a vehicle including the display device. Background Technology

[0004] Typically, liquid crystal display (LCD) monitors in the prior art are manufactured with the LCD panel and a backlight unit located on the back of the LCD panel bonded together using adhesive. However, because the LCD panel is directly bonded to the backlight unit in the prior art, the impact generated by external forces applied to the backlight unit is completely transmitted to the LCD panel, resulting in shape deformation of the LCD panel. LCD panel deformation is a major cause of light leakage.

[0005] In particular, unlike existing LCD monitors with flat shapes, light leakage is further increased in curved LCD monitors with curved surface shapes and structures in which the LCD panel and backlight unit are bonded together as in the prior art. This increased light leakage becomes an obstacle to manufacturing curved LCD monitors using LCD panels. Summary of the Invention

[0006] This disclosure aims to provide a display device having a structure that prevents light leakage by minimizing the impact of the external force on the liquid crystal display (LCD) panel, even when an external force is applied to the backlight unit.

[0007] In one aspect, the present disclosure provides a display device comprising: a backlight unit disposed at the rear side of the display device; a display panel disposed at the front side of the backlight unit; and an outer cover disposed at the front side of the display panel, wherein the backlight unit is configured to press against the outer cover and spaced apart from the display panel.

[0008] The display panel can be attached to an external cover.

[0009] The backlight unit may include a guide panel, which is configured to face the outer peripheral area of ​​the display panel when the display device is viewed from the front of the outer cover. The guide panel may be configured to press against the outer cover and be spaced apart from the display panel.

[0010] The display device may also include a joint disposed between the guide panel and the outer cover, and configured to engage the guide panel to the outer cover.

[0011] The guide panel may include: a main body portion configured to define the body of the guide panel and extending in a forward / backward direction; and a first protrusion portion extending from the main body portion in a left / right direction.

[0012] When the display device is viewed from the front of the external cover, the first protruding portion can be configured to overlap with the display panel.

[0013] The guide panel may also include a second protrusion that extends from the body portion in a direction opposite to that of the first protrusion. A joint may engage the second protrusion to the outer cover.

[0014] The second protrusion can be positioned closer to the front than the first protrusion.

[0015] The backlight unit may further include: a sheet-like member disposed on the rear side of the display panel; a light guide portion disposed on the rear side of the sheet-like member and configured to be in close contact with the sheet-like member; and a reflective portion disposed on the rear side of the light guide portion and configured to be in close contact with the light guide portion.

[0016] The sheet-like member can be spaced apart from the display panel in a forward / backward direction. At least a portion of the first protrusion can be disposed in the space between the sheet-like member and the display panel.

[0017] The first protruding part can be spaced apart from the display panel in the forward / backward direction.

[0018] The thickness of the display panel can be greater than the thickness of the joint.

[0019] The display panel can be an LCD panel.

[0020] The backlight unit may also include a bottom cover disposed on the rear side of the reflector and configured to be in close contact with the reflector. The bottom cover may include: a rear region disposed on the rear side of the reflector and configured to be in close contact with the reflector; and a side region projecting forward from the outer periphery of the rear region and configured to surround the reflector.

[0021] In another aspect, this disclosure provides a vehicle including a display device, wherein the display device includes: a backlight unit disposed at the rear side of the display device; a display panel disposed at the front side of the backlight unit; and an outer cover disposed at the front side of the display panel, wherein the backlight unit is configured to press against the outer cover and spaced apart from the display panel.

[0022] According to this disclosure, a display device with such a structure can be manufactured that prevents light leakage by minimizing the impact of the external force on the LCD panel, even when an external force is applied to the backlight unit. Attached Figure Description

[0023] Figure 1 This is a cross-sectional view showing the component structure of the display device according to the present disclosure.

[0024] Figure 2 This is an exploded perspective view showing the structure of the display device according to the present disclosure. Detailed Implementation

[0025] In the following description, a display device according to the present disclosure and a vehicle including the display device are described with reference to the accompanying drawings.

[0026] When a component, device, element, etc., of this disclosure is described as having a purpose or performing an operation or function, the component, device, or element shall be regarded herein as "configured to" satisfy that purpose or perform that operation or function.

[0027] Display device

[0028] Figure 1 This is a cross-sectional view showing the component structure of the display device according to the present disclosure.

[0029] like Figure 1 As shown, component A of the display device 10 according to this disclosure may include: a backlight unit 100 disposed at the rear side of the display device; a display panel 200 disposed at the front side of the backlight unit 100; and an outer cover 300 disposed at the front side of the display panel 200. According to this disclosure, light emitted from the backlight unit 100 can be propagated to the outside through the display panel 200 and the outer cover 300. For example, the display panel 200 may be a liquid crystal display (LCD) panel. However, the display panel 200 may be a panel different from an LCD panel.

[0030] In this case, according to the present disclosure, the backlight unit 100 may be configured to press the outer cover 300 and be spaced apart from the display panel 200.

[0031] According to this disclosure, unlike the prior art, the backlight unit 100 is spaced apart from the display panel 200 without being in close contact with it. Therefore, even if an external force is applied to the backlight unit 100, the impact of the impact caused by the external force on the display panel 200 can be minimized. Therefore, according to this disclosure, light leakage in the display device 10 due to external forces can be prevented.

[0032] More specifically, the backlight unit 100 may include a guide panel 110, which is configured to face the outer peripheral region of the display panel 200 when the display device is viewed from the front side of the outer cover 300, i.e., when the display device 10 is viewed from the front side of the outer cover 300 in the forward / backward direction F. In this case, the guide panel 110 may be configured to press against the outer cover 300 and be spaced apart from the display panel 200.

[0033] Reference Figure 1 The component A of the display device 10 may further include a joint 400 disposed between the guide panel 110 and the outer cover 300 and configured to engage the guide panel 110 to the outer cover 300. The joint 400 may be double-sided tape having two opposing surfaces, each having adhesive strength. For example, the joint 400 may be made of polyurethane foam, but the type of joint 400 is not limited to this.

[0034] Furthermore, according to this disclosure, the display panel 200 can be bonded to the outer cover 300. In this case, because the display panel 200 defines the path of light, the bonding material used to bond the display panel 200 and the outer cover 300 can be light-transmitting. More specifically, the bonding material used to bond the display panel 200 and the outer cover 300 can be an optical bonding material.

[0035] Reference Figure 1 The guide panel 110 may include a main body portion 112 and a first protruding portion 114. The main body portion is configured to define the body of the guide panel 110 and extends in a forward / rearward direction F, while the first protruding portion extends from the main body portion 112 in a left / right direction W. In this configuration, when the display device 10 is viewed from the front side of the outer cover 300 in the forward / rearward direction F, the first protruding portion 114 may be configured to overlap with the display panel 200. Conversely, when the display device 10 is viewed from the front side of the outer cover 300 in the forward / rearward direction F, the main body portion 112 may be configured to be spaced apart from the display panel 200 without overlapping it.

[0036] Furthermore, according to this disclosure, the guide panel 110 may also include a second protrusion 116 that extends from the body portion 112 in a left / right direction W and in a direction opposite to that of the first protrusion 114. In this case, the engagement portion 400 can engage the second protrusion 116 to the outer cover 300.

[0037] Furthermore, the second protrusion 116 can be positioned closer to the front than the first protrusion 114. Therefore, the step portion can be positioned between the first protrusion 114 and the second protrusion 116 in the forward / backward direction F.

[0038] In addition, such as Figure 1 As shown, in addition to the guide panel 110, the backlight unit 100 may also include other components. For example, the backlight unit 100 may further include: a sheet member 120 disposed on the rear side of the display panel 200; a light guide portion 130 disposed on the rear side of the sheet member 120 and configured to be in close contact with the sheet member 120; and a reflective portion 140 disposed on the rear side of the light guide portion 130 and configured to be in close contact with the light guide portion 130. Furthermore, the sheet member 120 may have a structure with different material stacks. For example, the sheet member 120 may include a prism layer and a double brightness enhancement film (DBEF) layer.

[0039] In this configuration, the sheet member 120 may be spaced apart from the display panel 200 in the forward / backward direction F. In this configuration, at least a portion of the first protrusion 114 of the guide panel 110 may be disposed in the space between the sheet member 120 and the display panel 200. Therefore, according to this disclosure, the sheet member 120 may interfere with the first protrusion 114 and the display panel 200 may interfere with the first protrusion 114, thereby preventing the sheet member 120 and the display panel 200 from contacting each other. However, even in this configuration, the first protrusion 114 may be spaced apart from the display panel 200 in the forward / backward direction F. Therefore, according to this disclosure, contact between the first protrusion 114 and the display panel 200 can also be prevented.

[0040] In addition, such as Figure 1 As shown, the thickness of the display panel 200 can be greater than the thickness of the joint 400. Therefore, at least one area of ​​the second protrusion 116 can be configured to face the display panel 200.

[0041] Furthermore, the backlight unit 100 may also include a bottom cover 150 disposed at the rear side of the reflective portion 140 and configured to be in close contact with the reflective portion 140. In this case, the bottom cover 150 may further include a rear region 152 and a side region 154. The rear region is disposed at the rear side of the reflective portion 140 and configured to be in close contact with the reflective portion 140, and the side region protrudes forward from the outer peripheral region of the rear region 152 and is configured to surround the reflective portion 140. More specifically, the outer peripheral region of the reflective portion 140 may also protrude to have a shape corresponding to the side region 154. Furthermore, although not shown in the figures, the display device according to this disclosure may also include a light source. For example, the light source may be disposed in the side region 154 of the bottom cover 150 and configured to face the reflective portion 140.

[0042] Figure 2 This is an exploded perspective view showing the structure of the display device according to the present disclosure.

[0043] like Figure 2 As shown, the display device 10 may further include components for securing component A to a vehicle or the like. For example, the display device 10 may also include a mounting bracket B disposed at the rear side of component A and a rear housing R disposed at the rear side of the mounting bracket B.

[0044] Mounting bracket B can be configured to be in close contact with component A, and rear housing R can be configured to be in close contact with mounting bracket B. For this purpose, a PEM nut P can be located in the outer peripheral region of the rear surface of component A and protrude rearward. The PEM nut P passes through mounting bracket B and rear housing R and can be screwed on, i.e., tightened.

[0045] Furthermore, the display device 10 according to this disclosure can be a curved display device with a curved surface. Therefore, the components A, mounting bracket B, and rear housing R that constitute the display device 10 can have curved surfaces with shapes corresponding to each other. Of course, the backlight unit 100, display panel 200, and outer cover 300 that constitute component A can also have curved surfaces with shapes corresponding to the shapes of the curved surfaces.
