[0008] One embodiment of the present invention will be described below with reference to the drawings.

[0009] (Configuration of display device 100) Figure 1 is an external perspective view showing the front side of the display device 100 according to one embodiment. Figure 2 is an external perspective view showing the rear side of the display device 100 according to one embodiment.

[0010] In the following explanation, the direction corresponding to the vertical direction of the display 121 will be referred to as the up-and-down direction (Z-axis direction). The direction corresponding to the horizontal direction of the display 121 will be referred to as the width direction and the left-right direction (Y-axis direction). The direction corresponding to the depth direction of the display 121 will be referred to as the front-to-back direction (X-axis direction).

[0011] However, the direction to the left (positive Y-axis direction) when viewed from the back of the display (negative X-axis side) is defined as the left direction, and the direction to the right (negative Y-axis direction) when viewed from the back of the display (negative X-axis side) is defined as the right direction.

[0012] The display device 100 shown in Figures 1 and 2 has a display surface 121A of a display 121 on its front (the positive X-axis side) and is connected to an external device (e.g., a laptop computer, smartphone, etc.) via a cable 10. It is capable of displaying various images (videos, still images, etc.) transmitted from the external device via the cable 10 on the display surface 121A of the display 121. In other words, the display device 100 is a thin, portable display device with a built-in battery, and can be carried together with an external device and used as an extended display for the external device by connecting to the external device when needed.

[0013] As shown in Figures 1 and 2, the display device 100 comprises a resin housing 110 that forms the external shape of the display device 100. The housing 110 has a thin section 111 and a thick section 112.

[0014] The thin portion 111 is a plate-like part that constitutes the front side (positive Z-axis side) of the housing 110. The thin portion 111 has a horizontally elongated rectangular shape when viewed from the front (positive X-axis direction) or rear (negative X-axis direction) in plan view. The thin portion 111 is a relatively thin portion in the depth direction (X-axis direction). A display 121 is provided on the thin portion 111. A rectangular opening 111A is formed on the front side (positive X-axis side) of the thin portion 111, and the display surface 121A of the display 121 is exposed through this opening 111A. For example, an organic EL (Electro-Luminescence) display, a liquid crystal display, etc., can be used as the display 121.

[0015] In the thin portion 111, a touch sensor 122 is provided overlapping the display surface 121A of the display 121. The touch sensor 122 receives various input operations (for example, selection operations, handwritten input operations, etc.). As the touch sensor 122, for example, a capacitive touch panel or the like can be used.

[0016] The thick portion 112 is a plate-like portion that constitutes the back side (negative X-axis side) of the housing 110, and is provided protruding rearward from the lower part of the back of the thin portion 111. The thick portion 112 is a portion having a relatively large thickness in the depth direction (X-axis direction). The thick portion 112 has a horizontally long rectangular shape in a plan view from the rear (negative X-axis direction). However, the thick portion 112 has an upper and lower width and a left and right width so as not to protrude from the thin portion 111 in a plan view from the rear (negative X-axis direction). The thick portion 112 houses a control board 131, a battery 133 (both shown in FIG. 4), etc. Further, an interface portion 123 (see FIG. 3) to which the connector 11 of the cable 10 is connected is provided on the back surface of the thick portion 112. The interface portion 123 is, that is, a "terminal" to which the connector 11 of the cable 10 is connected.

[0017] In addition, switches 134 and 135 are provided on the left side (positive Y-axis side) side surface of the thick portion 112. The switches 134 and 135 are, for example, a power button, a selection button, an OK button, a return button, etc.

[0018] (Configuration of the back of the display device 100) FIG. 3 is a rear view and a side view of a display device 100 according to an embodiment. FIG. 3(a) is a rear view of a display device 100 according to an embodiment. FIG. 3(b) is a side view of a display device 100 according to an embodiment.

[0019] As shown in FIG. 3, a recess 113 is formed on the back surface of the thick portion 112 of the housing 110. The recess 113 is a portion recessed with a certain depth toward the front (positive X-axis direction). In the example shown in FIG. 3, the recess 113 has a rectangular shape in a plan view from the rear, but the shape of the recess 113 is not limited to this.

[0020] As shown in Figure 3, the interface portion 123 is provided exposed within the recess 113 of the thick portion 112. In particular, in the example shown in Figure 3, the interface portion 123 is provided exposed within the recess 113 from the inner wall surface 113A on the left side (positive Y-axis side) of the recess 113 of the thick portion 112.

[0021] As a result, the display device 100 according to one embodiment can connect the connector 11, which is provided at one end of the cable 10, to the interface unit 123 with the connector positioned within the recess 113, as shown in Figure 3.

[0022] In other words, in one embodiment of the display device 100, the connector 11 of the cable 10 can be connected to the interface unit 123 without protruding from the side of the housing 110.

[0023] Therefore, according to the display device 100 of one embodiment, the display device 100 and external devices can be placed side by side.

[0024] Furthermore, according to the display device 100 of one embodiment, sudden loads on the connector 11 of the cable 10 can be prevented, thereby reducing the risk of damage to the interface unit 123.

[0025] Examples of the cable 10 include USB (Universal Serial Bus) cables and HDMI (High-Definition Multimedia Interface) (registered trademark) cables. The interface section 123 is made of a shape that fits the connector 11 of the cable 10.

[0026] Furthermore, the depth of the recess 113 (depth in the X-axis direction) is greater than the thickness of the connector 11 and the outer diameter of the cable 10. As a result, in one embodiment of the display device 100, as shown in Figure 3(b), the interface portion 123 can connect the cable 10 (including the connector 11) in the recess 113 without it protruding outside (negative X-axis side) beyond the back surface of the thick portion 112.

[0027] As a result, according to the display device 100 of one embodiment, it is possible to prevent sudden loads on the connector 11 of the cable 10 from the back side of the thick portion 112.

[0028] Furthermore, as shown in Figure 3, the thick section 112 has an outlet 113B that allows the cable 10 to be pulled out from the recess 113 to the upper side of the thick section 112. Specifically, the outlet 113B has a groove-like shape that extends upward (in the positive Z-axis direction) from the upper right corner (positive Z-axis side and negative Y-axis side) of the recess 113 and connects to the space above the thick section 112. The depth of the outlet 113B (depth in the X-axis direction) is the same as the depth of the recess 113 (depth in the X-axis direction).

[0029] As a result, according to the display device 100 of one embodiment, the cable 10 can be pulled out from the recess 113 to the upper side of the thick portion 112 without the cable 10 protruding outward (negative X-axis side) beyond the back surface of the thick portion 112.

[0030] Furthermore, as shown in Figure 3, the thick section 112 has a fastener 114 for securing the cable 10 to the outlet 113B. Specifically, the fastener 114 is positioned so that both ends of the fastener 114 in the left-right direction (Y-axis direction) can be fixed to the thick section 112 by a snap-in method, with the fastener 114 straddling the outlet 113B in the left-right direction (Y-axis direction).

[0031] As a result, according to the display device 100 of one embodiment, the cable 10 can be secured to the outlet 113B by the fastener 114 so that the cable 10 does not fall out of the outlet 113B. Furthermore, according to the display device 100 of one embodiment, even if a load such as pulling occurs on the cable 10, the fastener 114 can withstand the load, thereby reducing the risk of damage to the interface section 123.

[0032] Furthermore, as shown in Figure 3, the upper surface 112A of the thickened portion 112 allows the cable 10 pulled out from the outlet 113B to be guided along the upper surface 112A.

[0033] As a result, the display device 100 according to one embodiment can easily route the cable 10 pulled out from the outlet 113B along a predetermined routing path.

[0034] Furthermore, as shown in Figure 3, the thick portion 112 has a clamp 115 capable of holding the cable 10 whose routing path is guided by the upper surface 112A of the thick portion 112.

[0035] As a result, the display device 100 according to one embodiment can reliably hold the cable 10 pulled out from the outlet 113B along a predetermined routing path.

[0036] In the example shown in Figure 3, the thick section 112 has two clamps 115, one for the cable 10 routing path to the right of the outlet 113B (negative Y-axis side) and another for the cable 10 routing path to the left of the outlet 113B (positive Y-axis side).

[0037] As a result, in one embodiment of the display device 100, the cable 10 can be reliably held along the installation path by the two clamps 115, regardless of whether the cable 10 is pulled out from the outlet 113B to the left (positive Y-axis direction) or to the right (negative Y-axis direction).

[0038] In the example shown in Figure 3, the interface portion 123 is located on the back surface of the thick portion 112, to the left of the center in the left-right direction (Y-axis direction) (positive Y-axis side), while the outlet 113B is located in the center in the left-right direction (Y-axis direction).

[0039] As a result, in one embodiment of the display device 100, the cable 10 connected to the interface section 123 can be bent without force and pulled out from the outlet 113B (i.e., the central part in the left-right direction (Y-axis direction)) to the upper side of the thick section 112.

[0040] Furthermore, in one embodiment of the display device 100, the direction in which the cable 10 is pulled out from the outlet 113B can be either to the left (positive Y-axis direction) or to the right (negative Y-axis direction).

[0041] In this embodiment, the display device 100 has an outlet 113B in the center in the left-right direction (Y-axis direction). Therefore, the length of the portion of the cable 10 guided along the upper surface of the thick portion 112 can be made equal whether the cable 10 is pulled out from the outlet 113B to the left (positive Y-axis direction) or to the right (negative Y-axis direction). In other words, the length of the portion of the cable 10 pulled out to the outside from the housing 110 can be made equal. For this reason, the display device 100 according to this embodiment can maintain a constant cable length regardless of whether the external device to be connected is positioned to the left or to the right.

[0042] Furthermore, in the example shown in Figure 3, two interface portions 123 are provided side by side in the vertical direction (Z-axis direction) on the inner wall surface 113A on the positive Y-axis side of the recess 113 of the thick portion 112. As a result, the display device 100 according to one embodiment can connect two cables 10 within the recess 113, and two external devices can be connected via the two cables 10. Moreover, in the example shown in Figure 3, the outlet 113B has a width greater than (outer diameter of cable 10 × 2) so that the two cables 10 can be pulled out side by side.

[0043] Furthermore, as shown in Figure 3, in one embodiment of the display device 100, a stand 136 is provided in the thick portion 112 so as to be housed therein. As shown in Figure 3, the stand 136 has a pivot shaft 136X at its upper end and is provided so as to be rotatable about the pivot shaft 136X.

[0044] Furthermore, the stand 136 has a rectangular frame shape. On the other hand, a storage groove 112B, which has the same shape as the stand 136, is formed in the thick portion 112. Therefore, in the display device 100 according to one embodiment, the stand 136 can be stored in the storage groove 112B without protruding from the back surface of the thick portion 112.

[0045] As shown in Figures 1 and 2, in one embodiment of the display device 100, the housing 110 can be made to stand on its own on the installation surface by rotating the stand 136 from the stored position to the open position. Furthermore, in one embodiment of the display device 100, the tilt of the housing 110 relative to the installation surface can be adjusted by adjusting the opening angle of the stand 136.

[0046] Furthermore, the pivot axis 136X of the stand 136 is located below the upper surface 112A of the thick portion 112. Therefore, in one embodiment of the display device 100, the opening and closing operation of the stand 136 does not interfere with the cable 10 which is arranged along the upper surface 112A of the thick portion 112.

[0047] Furthermore, as shown in Figure 3, when the cable 10 is pulled out from outlet 113B in the rightward direction (negative Y-axis direction), the two clamps 115 located to the right of outlet 113B (negative Y-axis side) hold the cable 10, while the two clamps 115 located to the left of outlet 113B (positive Y-axis side) are free.

[0048] Therefore, in one embodiment of the display device 100, the cable 10 can be folded back near the right end (negative Y-axis side) of the housing 110, and the other end of the cable 10 can be held by a clamp 115 provided to the left of the outlet 113B (positive Y-axis side).

[0049] As a result, the display device 100 according to one embodiment can securely hold the cable 10 without it protruding from the housing 110 when the display device 100 is not in use (during transport, storage, etc.), and can store the cable 10 in a retracted state.

[0050] Furthermore, in the display device 100 according to one embodiment, the connector 11 at one end of the cable 10 is connected to the interface portion 123 without protruding rearward (in the negative X-axis direction) from the recess 113 of the thick portion 112. Therefore, even when not in use (during transport, storage, etc.), load is less likely to be placed on the connector 11 at one end. For this reason, the display device 100 according to one embodiment can store the cable 10 while the connector 11 at one end remains connected to the interface portion 123.

[0051] In one embodiment of the display device 100, the difference between the thickness of the thick portion 112 and the thickness of the thin portion 111 is greater than the outer diameter of the cable 10. As a result, in one embodiment of the display device 100, the portion of the cable 10 that is pulled out from the outlet 113B can be positioned on the back of the thin portion 111 above the thick portion 112, so that the cable 10 does not protrude outward (negative X-axis side) beyond the back surface of the thick portion 112.

[0052] (Internal configuration of the display device 100) Figure 4 is a rear view showing the internal configuration of a display device 100 according to one embodiment.

[0053] As shown in Figure 4, the thick portion 112 of the housing 110 is divided into a left gripping portion R1, an intermediate portion R3, and a right gripping portion R2 by a storage groove 112B.

[0054] Specifically, the storage groove 112B has a first storage section 112Ba that extends in the vertical direction (Z-axis direction) and stores the left frame portion of the stand 136, and a second storage section 112Bc that extends in the vertical direction (Z-axis direction) and stores the right frame portion of the stand 136.

[0055] The left gripping portion R1 of the thick section 112 is the portion to the left (positive Y-axis side) of the first storage portion 112Ba of the storage groove 112B. The left gripping portion R1 has a certain width from the left side of the housing 110. The left gripping portion R1 is the portion that is gripped by the user's right hand when the user grips the housing 110 with both hands from the front side (positive X-axis side) of the housing 110. The left gripping portion R1 has a hollow structure. The internal space of the left gripping portion R1 is not connected to the internal space of the intermediate portion R3.

[0056] The right gripping portion R2 of the thick section 112 is the portion to the right (negative Y-axis side) of the second storage portion 112Bc of the storage groove 112B. The right gripping portion R2 has a certain width from the right side of the housing 110. The right gripping portion R2 is the portion that is gripped by the user's left hand when the user grips the housing 110 with both hands from the front side (positive X-axis side) of the housing 110. The right gripping portion R2 has a hollow structure. The internal space of the right gripping portion R2 is not connected to the internal space of the intermediate portion R3.

[0057] The intermediate portion R3 of the thick section 112 is the portion between the first storage section 112Ba and the second storage section 112Bc of the storage groove 112B. The intermediate portion R3 has a hollow structure.

[0058] As shown in Figure 4, the control board 131 and battery 133 are located inside the thick section 112.

[0059] The control board 131 is connected to the interface unit 123, and various electronic components are mounted on it to construct a control circuit that controls the operation of the display device 100.

[0060] Battery 133 supplies power to drive the display device 100. Various rechargeable secondary batteries (e.g., lithium-ion batteries, lithium polymer batteries, etc.) are used for battery 133. The display device 100 can also be charged by receiving power from an external device via cable 10 and interface unit 123.

[0061] Here, as shown in Figure 4, the high-temperature components, the control board 131 and the battery 133, are located inside the intermediate section R3. In other words, in the first example shown in Figure 4, the high-temperature components, the control board 131 and the battery 133, are not located inside either the left gripping section R1 or the right gripping section R2. Furthermore, in the first example shown in Figure 4, no other high-temperature components are located inside either the left gripping section R1 or the right gripping section R2.

[0062] As a result, in one embodiment of the display device 100, when the user grasps the housing 110 with both hands from the front side (positive X-axis side) of the housing 110, the left gripping portion R1 and the right gripping portion R2 that the user's hands touch can be prevented from becoming hot.

[0063] Furthermore, since the display device 100 according to one embodiment does not actively dissipate the heat emitted from the control board 131 and the battery 133 to the display 121, it is possible to suppress the display 121 from becoming overheated.

[0064] In particular, the display device 100 according to one embodiment includes a frame-shaped stand 136 that is rotatable and can be stored in a storage groove 112B formed on the back surface of the thick portion 112 of the housing 110, and the thick portion 112 of the housing 110 is divided by the storage groove 112B into a left gripping portion R1 and a right gripping portion R2, and an intermediate portion R3 provided between the left gripping portion R1 and the right gripping portion R2.

[0065] In other words, in the display device 100 according to one embodiment, the stand 136 is arranged to surround the interface section 123, and the left gripping section R1 and the right gripping section R2 are arranged outside the stand 136.

[0066] As a result, in one embodiment of the display device 100, the storage groove 112B allows the left gripping portion R1 and the right gripping portion R2 to be spatially separated from the intermediate portion R3, thereby suppressing the propagation of heat emitted from high-temperature components in the intermediate portion R3 to the left gripping portion R1 and the right gripping portion R2.

[0067] Furthermore, in one embodiment of the display device 100, the stand 136 can be made so as not to interfere with the hand that is gripping the left gripping part R1 and the right gripping part R2.

[0068] Furthermore, it is preferable that the interior of the left gripping portion R1 and the right gripping portion R2 have a width greater than the area that the user's hand touches. For example, in this embodiment, the interior of the left gripping portion R1 and the right gripping portion R2 have a width greater than the length corresponding to the distance from the tip of the user's fingertips to the second joint, considering that when the user grips the housing 110 with both hands from the front side (positive X-axis side) of the housing 110, the user's fingertips to the second joint touch these areas.

[0069] (First variation) Figure 5 is a rear view showing a first modified example of the internal configuration of the display device 100 according to one embodiment. Figure 6 is a cross-sectional view showing a first modified example of the internal configuration of the display device 100 according to one embodiment.

[0070] In the examples shown in Figures 5 and 6, the control board 131 (high-temperature component) has electronic components 131A and 131B mounted on it, which are sources of high temperature.

[0071] Furthermore, in the example shown in Figures 5 and 6, the display device 100 according to one embodiment includes a thermal conductive sheet 137 attached to the inner surface of the thick portion 112 of the housing 110 at a position facing the control substrate 131 (high-temperature component). The thermal conductive sheet 137 is made of a sheet-like material with high heat conductivity (for example, aluminum foil).

[0072] As a result, in one embodiment of the display device 100, the heat emitted from the electronic components 131A and 131B of the control board 131 is transferred to the entire heat conductive sheet 137, thereby suppressing a localized increase in the temperature of the intermediate portion R3 of the thick portion 112 of the housing 110. This configuration is useful because even the intermediate portion R3 may be touched by the user's hand.

[0073] (Second variation) Figure 7 is a rear view showing a second modified example of the internal configuration of the display device 100 according to one embodiment.

[0074] In the example shown in Figure 7, the thermal conductive sheet 137 is attached to a wide area on the inner surface of the thick portion 112 of the housing 110, encompassing the position facing the control board 131 (high-temperature component) and the position facing the battery 133 (high-temperature component).

[0075] As a result, in one embodiment of the display device 100, the heat emitted from the control board 131 and the heat emitted from the battery 133 are transmitted to the entire heat conductive sheet 137 over a wider area than in the first modified example, thereby suppressing localized temperature increases in the intermediate R3 of the thick portion 112 of the housing 110.

[0076] (Third variation) Figure 8 is a rear view showing a third modified example of the internal configuration of the display device 100 according to one embodiment. Figure 9 is a cross-sectional view showing a third modified example of the internal configuration of the display device 100 according to one embodiment.

[0077] Furthermore, in the example shown in Figures 8 and 9, the display device 100 according to one embodiment includes a heat transfer member 138 positioned between the back surfaces of the opposing displays 121 and the back surface of the housing 110 (excluding the left gripping portion R1 and the right gripping portion R2). The heat transfer member 138 is a sheet-like material made of a material with high heat conductivity (for example, aluminum foil, heat-transferring rubber, etc.).

[0078] As a result, the display device 100 according to one embodiment can suppress the display 121 from becoming overheated by releasing the heat emitted from the display 121 to the back of the housing 110 (excluding the left grip portion R1 and the right grip portion R2) via the heat transfer member 138. This configuration is useful because the display 121 may also be touched by the user's hand for touch operation.

[0079] (Fourth variation) Figure 10 is a rear view showing a fourth modified example of the internal configuration of the display device 100 according to one embodiment. Figure 11 is a cross-sectional view showing a fourth modified example of the internal configuration of the display device 100 according to one embodiment.

[0080] In the example shown in Figures 10 and 11, the display device 100 according to one embodiment includes a sheet-like heat insulating member 139 positioned between the back surfaces of the display 121 and the control board 131 (high-temperature component) and battery 133 (high-temperature component), which are facing each other.

[0081] As a result, the display device 100 according to one embodiment can suppress the transfer of heat from the control board 131 and the battery 133 to the display 121, thereby preventing the display 121 from becoming overheated.

[0082] (Fifth variation) Figure 12 is a cross-sectional view showing a fifth modified example of the internal configuration of the display device 100 according to one embodiment.

[0083] In the example shown in Figure 12, the display device 100 according to one embodiment includes a sheet-like heat insulating member 139 positioned between the back surfaces of the display 121 and the control board 131 (high-temperature component) and battery 133 (high-temperature component), which face each other, similar to the fourth modified example.

[0084] Furthermore, in the example shown in Figure 12, the display device 100 according to one embodiment includes a heat transfer member 138 positioned between the back surface of the display 121 and the heat insulating member 139, which are facing each other.

[0085] As a result, the display device 100 according to one embodiment can suppress the transfer of heat from the control board 131 and the battery 133 to the display 121, thereby preventing the display 121 from becoming overheated.

[0086] In addition, the display device 100 according to one embodiment can also suppress the display 121 from becoming overheated by releasing the heat emitted from the display 121 to the heat transfer member 138.

[0087] Although preferred embodiments of the present invention have been described in detail above, the present invention is not limited to these embodiments, and various modifications or changes are possible within the scope of the gist of the present invention as described in the claims.

[0088] Furthermore, the left gripping section R1 and the right gripping section R2 do not necessarily need to contain any components, and components that do not become hot (for example, a speaker, antenna, etc.) may be provided inside them.

[0089] Furthermore, the left gripping portion R1 and the right gripping portion R2 may be configured so that the user can easily recognize them. For example, the left gripping portion R1 and the right gripping portion R2 may have a shape that allows the user's hand to rest on them. Also, for example, the left gripping portion R1 and the right gripping portion R2 may be indicated by a different color from the intermediate portion R3. [Explanation of symbols]
