[0009] [Embodiment 1] FIG. 1 is a view showing the front surface of a display module 1 according to Embodiment 1 of the present invention. FIG. 2 is a view showing the back surface of the display module 1 according to Embodiment 1 of the present invention. As shown in these figures, the display module 1 includes a display panel 2, a support frame 4, and a back chassis 6.

[0010] The display panel 2 is a component that displays various types of information such as still images, text, and videos. In the present embodiment, the display panel 2 is a self-luminous display panel 2, for example, an organic EL panel having organic EL (Electro Luminescence) elements. The back chassis 6 is a protective structure for protecting the back surface of the display module 1. The back chassis 6 is disposed behind the display panel 2. The support frame 4 is a support structure for supporting the peripheral portion of the display module 1. The support frame 4 is disposed behind the peripheral portion of the display panel 2.

[0011] FIG. 3 is a view showing the inside of the display module 1. This figure shows the front surface of the display module 1 with the display panel 2 removed. As shown in FIG. 3, the display module 1 further includes a heat sink 8 (rear member) disposed inside the display module 1. The heat sink 8 is disposed behind the display panel 2 and in front of the back chassis 6. In other words, the back chassis 6 is disposed behind the heat sink 8. The heat sink 8 is made of a material having high thermal conductivity such as metal, and has a role of removing heat generated in the display panel 2 from the display panel 2 and discharging it to the outside of the display module 1.

[0012] As shown in FIG. 3, the support frame 4 has an upper frame 41 (partial frame), a left frame 42 (horizontal frame, partial frame), a right frame 43 (horizontal frame, partial frame), and a lower frame 44. The upper frame 41 is disposed at a position corresponding to the upper peripheral edge (peripheral edge) of the display module 1. The left frame 42 is disposed at a position corresponding to the left peripheral edge (peripheral edge) of the display module 1. The right frame 43 is disposed at a position corresponding to the right peripheral edge (peripheral edge) of the display module 1. The lower frame 44 is disposed at a position corresponding to the lower peripheral edge of the display module 1.

[0013] FIG. 4 is a cross-sectional view showing a cross-section near the upper frame 41 in the display module 1. The left side in FIG. 4 corresponds to the front side of the display module 1, and the right side in FIG. 4 corresponds to the rear side of the display module 1. As shown in this figure, the portion facing the heat dissipation plate 8 on the back surface of the display panel 2 is fixed to the front surface of the heat dissipation plate 8 by a double-sided tape 11 (first fastening member). The double-sided tape 11 is made of a material with high thermal conductivity and efficiently transfers the heat generated in the display panel 2 to the heat dissipation plate 8. The double-sided tape 1 2 is , like the double-sided tape 11, is made of a material with high thermal conductivity and efficiently transfers the heat transferred from the display panel 2 to the heat dissipation plate 8 to the back chassis 6.

[0014] The upper end portion of the display panel 2 is exposed outside the display module 1. In other words, the upper frame 41 does not have a portion covering the upper end portion of the display panel 2. The front surface of the upper frame 41 is not connected to the back surface of the upper peripheral edge portion of the display panel 2. That is, the front surface of the upper frame 41 is separated from the back surface of the upper peripheral edge portion of the display panel 2. In other words, there is a certain space between the front surface of the upper frame 41 and the back surface of the upper peripheral edge portion of the display panel 2. On the other hand, the back surface of the upper frame 41 is fixed to the front surface of the back chassis 6 by a double-sided tape 13 (the second fastening member) .

[0015] The lower end portion 21 of the upper frame 41 facing the upper end portion 31 of the back chassis 6 is spaced apart from the upper end portion 31 of the back chassis 6. Also, the lower end portion 22 of the upper frame 41 facing the upper end portion 32 of the heat dissipation plate 8 is spaced apart from the upper end portion 32 of the heat dissipation plate 8. In the example of FIG. 4, the distance between the lower end portion 21 and the upper end portion 31 is smaller than the distance between the lower end portion 22 and the upper end portion 32.

[0016] FIG. 5 is a cross-sectional view showing a cross-section in the vicinity of the left frame 42 in the display module 1. The lower side in FIG. 5 corresponds to the front side of the display module 1, and the upper side in FIG. 5 corresponds to the rear side of the display module 1. As shown in this figure, the front surface of the left frame 42 is not connected to the left peripheral edge portion of the display panel 2. That is, the front surface of the left frame 42 is spaced apart from the left peripheral edge portion of the display panel 2. In other words, there is a certain space between the front surface of the left frame 42 and the left peripheral edge portion of the display panel 2. On the other hand, the back surface of the left frame 42 is fixed to the front surface of the back chassis 6 by the double-sided tape 13.

[0017] FIG. 6 is a cross-sectional view showing a cross-section in the vicinity of the right frame 43 in the display module 1. The lower side in FIG. 6 corresponds to the front side of the display module 1, and the upper side in FIG. 6 corresponds to the rear side of the display module 1. As shown in this figure, the front surface of the right frame 43 is not connected to the right peripheral edge portion of the display panel 2. That is, the front surface of the right frame 43 is spaced apart from the right peripheral edge portion of the display panel 2. In other words, there is a certain space between the front surface of the right frame 43 and the right peripheral edge portion of the display panel 2. On the other hand, the back surface of the right frame 43 is fixed to the front surface of the back chassis 6 by the double-sided tape 13.

[0018] (Advantages of the display module 1) FIG. 7 is a diagram for explaining the advantages of the display module 1. Suppose a user of the display module 1 presses the upper frame 41 downward toward the display module 1. As a result, the upper frame 41 deforms downward toward the display module 1. At this time, since the back chassis 6 is fixed to the upper frame 41 via the double-sided tape 13, the force generated by the deformation of the upper frame 41 is transmitted to the back chassis 6 through the double-sided tape 13, and stress is applied to the back chassis 6. On the other hand, since the display panel 2 is separated from the upper frame 41, even if the upper frame 41 deforms, no stress is generated on the display panel 2. Thus, it is possible to prevent the deformation of the upper frame 41 from adversely affecting the display panel 2.

[0019] Although illustration is omitted, suppose a user of the display module 1 presses the left frame 42 to the right side of the display module 1. As a result, the left frame 42 deforms toward the right side of the display module 1. At this time, since the back chassis 6 is fixed to the left frame 42 via the double-sided tape 13, the force generated by the deformation of the left frame 42 is transmitted to the back chassis 6 through the double-sided tape 13, and stress is applied to the back chassis 6. On the other hand, since the display panel 2 is separated from the left frame 42, even if the left frame 42 deforms, no stress is generated on the display panel 2. Thus, it is possible to prevent the deformation of the left frame 42 from adversely affecting the display panel 2.

[0020] Although illustration is omitted, suppose a user of the display module 1 presses the right frame 43 to the left side of the display module 1. As a result, the right frame 43 deforms toward the left side of the display module 1. At this time, since the back chassis 6 is fixed to the right frame 43 via the double-sided tape 13, the force generated by the deformation of the right frame 43 is transmitted to the back chassis 6 through the double-sided tape 13, and stress is applied to the back chassis 6. On the other hand, since the display panel 2 is separated from the right frame 43, even if the right frame 43 deforms, no stress is generated on the display panel 2. Thus, it is possible to prevent the deformation of the right frame 43 from adversely affecting the display panel 2.

[0021] As described above, according to the present embodiment, there is provided a display module 1 that can prevent the upper frame 41, the left frame 42, or the right frame 43 from having an adverse effect on the display panel 2 when deformed.

[0022] Since the distance between the lower end portion 21 and the upper end portion 31 is smaller than the distance between the lower end portion 22 and the upper end portion 32, when the upper frame 41 is deformed downward of the display module 1, the lower end portion 21 contacts the upper end portion 31 before the lower end portion 22 contacts the upper end portion 32, preventing further deformation of the upper frame 41. Thereby, the stress received by the upper frame 41 can be dispersed.

[0023] (Modification example) The distance between the lower end portion 21 and the upper end portion 31 may be larger than the distance between the lower end portion 22 and the upper end portion 32. In this example, when the upper frame 41 is deformed downward of the display module 1, the lower end portion 22 contacts the upper end portion 32 before the lower end portion 21 contacts the upper end portion 31, preventing further deformation of the upper frame 41. Therefore, the stress received by the upper frame 41 can be dispersed.

[0024] Alternatively, the distance between the lower end portion 21 and the upper end portion 31 may be the same as the distance between the lower end portion 22 and the upper end portion 32. In this example, when the upper frame 41 is deformed downward of the display module 1, the lower end portion 22 contacts the upper end portion 32 before the lower end portion 21 contacts the upper end portion 31. Therefore, further deformation of the upper frame 41 is prevented, and the stress received by the upper frame 41 can be dispersed.

[0025] As described above, the distance between the lower end portion 21 and the upper end portion 31 may be the same as the distance between the lower end portion 22 and the upper end portion 32, or one may be smaller than the other.

[0026] 〔Embodiment 2〕 FIG. 8 is a cross-sectional view showing a cross-section near the upper frame 41A in the display module 1A according to Embodiment 2 of the present invention. The left side in FIG. 8 corresponds to the front side of the display module 1A, and the right side in FIG. 8 corresponds to the back side of the display module 1A. As shown in this figure, the display module 1A includes a display panel 2, a support frame 4A, a back chassis 6, and a heat dissipation plate 8. Since the configurations of the display panel 2, the back chassis 6, and the heat dissipation plate 8 are the same as those in Embodiment 1, detailed descriptions thereof are omitted.

[0027] The display module 1A is different from the display module 1 in that the structure of the support frame 4A is different from the structure of the support frame 4 in Embodiment 1. Specifically, the upper frame 41A of the support frame 4A has a portion that covers the upper end portion (end portion) of the display panel 2. Therefore, the upper end portion of the display panel 2 is not exposed outside the display module 1 and is hidden inside the display module 1. Although illustration is omitted, the right frame 43A has a structure that covers the right end portion of the display panel 2, similar to the upper frame 41A. Further, the left frame 42A has a structure that covers the left end portion of the display panel 2, similar to the upper frame 41A.

[0028] As shown in FIG. 8, the lower end portion 23 (first end portion) of the upper frame 41 A opposite to the upper end portion 33 of the display panel 2 is separated from the upper end portion 33 of the display panel 2. In the example of FIG. 8, the distance (first distance) between the lower end portion 23 and the upper end portion 33 is larger than the distance (second distance) between the lower end portion 21 (second end portion) and the upper end portion 31. Further, the distance between the lower end portion 2 3 and and the upper end portion 33 is larger than the distance (third distance) between the lower end portion 22 (the third end) and the upper end portion 32.

[0029] FIG. 9 is a diagram for explaining the advantages of the display module 1A. Assume that a user of the display module 1A presses the upper frame 41A downward below the display module 1. As a result, the upper frame 41A deforms downward. At this time, since the back chassis 6 is fixed to the upper frame 41A via the double-sided tape 13, the force generated by the deformation of the upper frame 41A is transmitted to the back chassis 6 through the double-sided tape 13, and stress is applied to the back chassis 6. On the other hand, since the display panel 2 is separated from the upper frame 41A, no stress is generated on the display panel 2 even if the upper frame 41A is deformed. Thereby, it is possible to prevent adverse effects on the display panel 2.

[0030] Although detailed description is omitted, when the left frame 42A or the right frame 43A is deformed, no stress is generated on the display panel 2 because the display panel 2 is separated from the left frame 42A and the right frame 43A. As described above, according to the present embodiment, there is provided a display module 1A that can prevent adverse effects on the display panel 2 when the upper frame 41A, the left frame 42A, or the right frame 43A is deformed.

[0031] Also, as shown in FIG. 9, since the distance between the lower end portion 23 and the upper end portion 33 is larger than the distance between the lower end portion 21 and the upper end portion 31, the upper frame 41A contacts the upper end portion 31 of the back chassis 6 before contacting the upper end portion 33 of the display panel 2. Thereby, further deformation of the upper frame 41 is prevented. Therefore, since the upper frame 41A does not need to contact the upper end portion 33, it is possible to prevent the upper end portion 33 side of the display panel 2 from being damaged when the upper frame 41 is deformed.

[0032] (Modification example) The distance between the lower end portion 23 and the upper end portion 33 may be greater than at least either the distance between the lower end portion 21 and the upper end portion 31 or the distance between the lower end portion 22 and the upper end portion 32. That is, the distance between the lower end portion 23 and the upper end portion 33 may be smaller than the distance between the lower end portion 21 and the upper end portion 31 and greater than the distance between the lower end portion 22 and the upper end portion 32. Alternatively, the distance between the lower end portion 23 and the upper end portion 33 may be greater than the distance between the lower end portion 21 and the upper end portion 31 and smaller than the distance between the lower end portion 22 and the upper end portion 32. In any case, when the upper frame 41A is deformed, the upper frame 41A contacts the back chassis 6 or the heat dissipation plate 8 before contacting the upper end portion 33 of the display panel 2, and the upper frame 41A is not deformed any further. As a result, the upper frame 41A does not need to contact the upper end portion 33 of the display panel 2, so that it is possible to prevent the upper end portion 33 side of the display panel 2 from being damaged.

[0033] 〔Embodiment 3〕 FIG. 10 is a cross-sectional view showing a cross-section in the vicinity of the upper frame 41 in the display module 1B according to Embodiment 3 of the present invention. The left side in FIG. 10 corresponds to the front side of the display module 1B, and the right side in FIG. 10 corresponds to the back side of the display module 1B. As shown in this figure, the display module 1B includes a display panel 2, a support frame 4, and a back chassis 6B. Since the configurations of the display panel 2 and the support frame 4 are the same as those in Embodiment 1, detailed descriptions thereof are omitted.

[0034] In the display module 1B according to the present embodiment, the back chassis 6B has a structure in which the back chassis 6 and the heat dissipation plate 8 in Embodiment 1 are integrated. The back chassis 6B has a portion corresponding to the back chassis 6 in Embodiment 1 and a portion corresponding to the heat dissipation plate 8 in Embodiment 1. Therefore, the thickness of the back chassis 6B is greater than the thickness of the back chassis 6. The back chassis 6B is made of a material with high thermal conductivity such as metal, and has a role of removing heat generated in the display panel 2 from the display panel 2 and releasing it to the outside of the display module 1. That is, the back chassis 6B also functions as the heat dissipation plate 8.

[0035] As shown in FIG. 10, the portion of the back surface of the display panel 2 facing the back chassis 6B is fixed to the front surface of the back chassis 6B by the double-sided tape 11. The thickness of the portion of the back chassis 6B where it is fixed to the display panel 2 is greater than the thickness of the portion of the heat sink 8 in Embodiment 1 where it is fixed to the display panel 2. Therefore, the heat dissipation performance of the back chassis 6B is greater than the heat dissipation performance of the heat sink 8. Furthermore, since the thickness of the back chassis 6B is greater than the thickness of the back chassis 6 in Embodiment 1, the strength of the back chassis 6B is greater than the strength of the back chassis 6.

[0036] As described above, according to the present embodiment, a display module 1B with higher heat dissipation efficiency and higher strength is provided.

[0037] 〔Embodiment 4〕 FIG. 11 is a cross-sectional view showing a cross-section near the upper frame 41C in the display module 1C according to Embodiment 4 of the present invention. The left side in FIG. 11 corresponds to the front side of the display module 1C, and the right side in FIG. 11 corresponds to the back side of the display module 1C. As shown in this figure, the display module 1C includes a display panel 2, a support frame 4C, a back chassis 6, and a heat sink 8. Since the configurations of the display panel 2, the back chassis 6, and the heat sink 8 are the same as those in Embodiment 1, detailed descriptions thereof are omitted.

[0038] The display module 1C is different from the display module 1 in that the structure of the support frame 4C is different from the structure of the support frame 4 in Embodiment 1. Specifically, the upper frame 41C of the support frame 4C has a recess 51 formed at a position facing the upper peripheral edge portion of the display panel 2 in the upper frame 41C. Although not shown, the left frame 42C has a recess 51 formed at a position facing the left peripheral edge portion of the display panel 2. The right frame 43C has a recess 51 formed at a position facing the right peripheral edge portion of the display panel 2.

[0039] In the display module 1C, when the force generated on the upper frame 41C cannot be fully absorbed by the back chassis 6 or the heat sink 8, the support frame 4C may tilt toward the display panel 2. At this time, since the upper peripheral portion of the display panel 2 faces the concave portion of the support frame 4C, even if the support frame 4C tilts toward the display panel 2, the upper peripheral portion of the display panel 2 will fit into the concave portion 51 of the upper frame 41C and will not contact the support frame 4C. Thus, it is possible to prevent stress from being applied to the upper peripheral portion of the display panel 2 when the support frame 4C tilts toward the display panel 2, and it is possible to prevent adverse effects on the display panel 2.

[0040] 〔Embodiment 5〕 FIG. 12 is a cross-sectional view showing the vicinity of the upper frame 41 in the display module 1D according to Embodiment 5 of the present invention. The display module 1D includes a display panel 2D, a support frame 4, a back chassis 6, and an optical member 61 (rear member). Since the configurations of the support frame 4 and the back chassis 6 are the same as those in Embodiment 1, detailed description thereof will be omitted.

[0041] The display panel 2D is a liquid crystal display panel having liquid crystal elements. Therefore, the display module 1D including the display panel 2D is a so-called liquid crystal display module. The optical member 61 is disposed behind the display panel 2D and is a member for irradiating light to the back surface of the display panel 2D. The optical member 61 may be any optical member such as, for example, a backlight, a light guide plate, a diffusion plate, an optical sheet, or a lens. The back surface of the display panel 2D is fixed to the front surface of the optical member 61 by a double-sided tape 11. The double-sided tape 11 is made of a material having a refractive index and light diffusion performance that do not adversely affect the information display on the display panel 2.

[0042] As shown in FIG. 12, the front surface of the upper frame 41 is not connected to the back surface of the upper peripheral portion of the display panel 2D. That is, the front surface of the upper frame 41 is spaced apart from the back surface of the upper peripheral portion of the display panel 2D. In other words, there is a certain space between the front surface of the upper frame 41 and the back surface of the upper peripheral portion of the display panel 2D. On the other hand, the back surface of the upper frame 41 is fixed to the front surface of the back chassis 6 by the double-sided tape 13. Thus, since the display panel 2D is spaced apart from the upper frame 41, even if the upper frame 41 is deformed, no stress is generated in the display panel 2D. Thereby, it is possible to prevent the upper frame 41 from deforming and adversely affecting the display panel 2D.

[0043] Although illustration is omitted, the front surface of the left frame 42 is not connected to the back surface of the left peripheral portion of the display panel 2D. That is, the front surface of the left frame 42 is spaced apart from the back surface of the left peripheral portion of the display panel 2D. Also, the front surface of the right frame 43 is not connected to the back surface of the right peripheral portion of the display panel 2D. That is, the front surface of the right frame 43 is spaced apart from the back surface of the right peripheral portion of the display panel 2D. Therefore, although detailed description is omitted, even when the left frame 42 or the right frame 43 is deformed, since the display panel 2D is spaced apart from the left frame 42 and the right frame 43, no stress is generated in the display panel 2D.

[0044] As described above, according to the present embodiment, there is provided a display module 1D that can prevent the upper frame 41, the left frame 42, or the right frame 43 from deforming and adversely affecting the display panel 2D.
