[0091] The rear cover is shown below. 110 with reference to Fig. 7A and Fig. 7B is described in more detail. <Ausführliche Konfiguration einer hinteren Beispielabdeckung>

[0092] Fig. Figure 7A is a top view of a rear cover of the display device according to an exemplary embodiment of the present disclosure. Fig. 7B is an enlarged view of a region. A " from Fig. 7A. As in Fig. As shown in 7A, the rear cover can be removed. 110 a mounting area FA , a support area PA and a flexible area MA include, in particular, the fastening area FA the printed circuit boards 140 and the flexible films 130 be attached in the support area PA are the multiple openings 111 Not arranged. In the flexible area MA can the multiple openings 111 be arranged. In this case, the rear cover can 110 a first support area PA1 on the upper section of the rear cover 110 and a second support area PA2 on the lower section of the rear cover 110 include the rear cover. 110 can also the mounting area FA between the first support area PA1 and the second support area PA2 include the rear cover. 110 can also provide an initial flexible area MA1 between the first support area PA1 and the fastening area FA and a second flexible area MA2 between the fastening area FA and the second support area PA2 include.

[0093] As in Fig. As shown in 7A, the first support area is PA1 the rear cover 110 the uppermost area of ​​the rear cover 110 and can be found at the header 164 be attached. The first support area PA1 can the first mounting holes AH1 include so that it is attached to the header 164 is attached. As above with reference to Fig. As described in section 3, the screws SC, which secure the headboard, can also be used. 164 and the first mounting holes AH1 penetrate, be intended to be in order to penetrate the header 164 at the first support area PA1 the rear cover 110 to attach. Since the first support area PA1 at the header 164 Furthermore, the rear cover can be attached. 110 move upwards or downwards simultaneously when the linkage unit 162 , which are located at the header 164 is attached, moves upwards or downwards. The display field 120 , which is on the rear cover 110 Once fixed, it can also move upwards or downwards. Fig. 7A provides five initial mounting holes AH1 as an example, but the number of initial mounting holes AH1 This can vary and is not limited to the example shown. Furthermore, it represents Fig. 7A shows that the rear cover 110 at the header 164 using the first mounting holes AH1 It may be attached. However, the present disclosure is not limited to this. The rear cover 110 can be found at the header 164 It can be attached without mounting holes.

[0094] As in Fig. As shown in 7A, this is the second support area PA2 the rear cover 110 the lowest part of the rear cover 110 and can play a role 151 be attached. The second support area PA2 can use second mounting holes AH2 include, so that he can participate in the role 151 is attached with screws SC , which plays the role 151 and the second mounting holes AH2 penetrate, may for example be intended to fulfill the role 151 at the second support area PA2 the rear cover 110 to attach. Since the second support area PA2 on the role 151 The rear cover can also be attached. 110 by rotating the roller 151 to play 151 wound up or unwound from it. Fig. 7A provides two second mounting holes AH2 as an example, but the number of second mounting holes AH2 may vary and is not limited to the example shown.

[0095] The fastening area FA can be an area that lies between the first support area PA1 and the second support area PA2 is arranged. The flexible films 130 , which are connected to one end of the display field 120 are connected, and the printed circuit boards 140 can in the fastening area FA be attached.

[0096] The fastening area FA can enable the flexible films 130 and the printed circuit boards 140 flat around the roll 151 to be wound up without being bent, in order to make the flexible films 130 and the printed circuit boards 140 to protect. Furthermore, the role can 151 It may also be partially flat, so that it corresponds to the mounting area FA and the mounting area FA keeps it flat. Details of this are given below with reference to Fig. 9A to Fig. 9C described.

[0097] Multiple mounting holes 112 can in the fastening area FA be arranged. Each of the multiple mounting holes 112 can choose between the flexible films 130 be arranged. Consequently, it is possible to use flexible films. 130 and the printed circuit boards 140 more stable together with a base plate 170 and a top cover 180 to attach, which through the multiple mounting holes 112 are attached. Without the use of mounting holes, the display section can become dislodged during winding or unwinding. DP the flexible films 130 and the printed circuit boards 140 , which are located in the fastening area FA The components are not securely fastened and can be shaken. In particular, during the winding or unwinding of the display section DP, the mounting area may be affected. FA the rear cover 110 A tension is applied, caused by contraction or expansion. Therefore, the multiple mounting holes can 112 in the fastening area FA be trained to handle the base plate 170 and the top cover 180 to attach to each other. Consequently, the flexible films can 130 and the printed circuit boards 140 , which are between the base plate 170 and the upper cover 180 are arranged to be more securely fastened. The number of multiple mounting holes 112 , which in Fig. The number shown in 7A is just an example and can vary depending on the number of printed circuit boards. 140 , the number of flexible films 130 and other design considerations may be modified. Details of the multiple mounting holes 112 are below with reference to Fig. 8A and Fig. 8B described.

[0098] The flexible area MA the rear cover 110 can around the role 151 together with the display field 120 to be wound up or unwound. The flexible area MA can at least with the display field 120 overlap among the other components of the DP display section.

[0099] The multiple openings 111 can in the flexible area MA the rear cover 110 be arranged. During the winding or unwinding of the display part. DP can the multiple openings 111 deformed by a stress applied to the display part DP is applied. In particular, during the winding or unwinding of the display section. DP the flexible area MA the rear cover 110 They will be deformed if the multiple openings... 111 contract or expand. Because of the multiple openings 111 Furthermore, a sliding phenomenon of the display field can occur if it can contract or expand. 120 , which is in the flexible area MA the rear cover 110 It is arranged, minimized, or suppressed. Therefore, the display field can be... 120 Applied tension is minimized or suppressed.

[0100] During the winding of the display panel 120 and the rear cover 110 Can there be a difference in length between the display field? 120 and the rear cover 110 consist of those who play a role 151 They are wound up. This is because there is a difference in the radius of curvature between the display field. 120 and the rear cover 110 exists. For example, if the rear cover 110 and the display field 120 to play 151 The rear cover can be wound up. 110 and the display field 120 require that different lengths go around the reel once 151 be wound up. That is, the display field 120 is further out of sorts 151 arranged away from the rear cover 110 and may therefore require a greater length to go once around the reel 151 It is wound up as the rear cover 110 In principle, a difference in the radius of curvature during the winding of the display part DP can result in a difference in length for winding the rear cover. 110 and the display field 120 cause. Consequently, the display field can 120 , which is on the rear cover 110 It is attached, slides, and moves from its original position. In this case, a phenomenon can occur where the display field... 120 from the rear cover 110 Due to differences in tension and radius of curvature caused by winding, the sliding can be defined as a sliding phenomenon. If excessive sliding occurs, the display field may 120 from the rear cover 110 They may be dissolved or defects such as cracks may occur.

[0101] In this case, the display device 100 According to an exemplary embodiment of the present disclosure, even if a voltage is applied to the indicator part DP while it is being wound or unwound, the multiple openings 111 the rear cover 110 can be flexibly deformed to fit the rear cover 110 and the display field 120 to reduce applied tension. For example, if the rear cover 110 and the display field 120 to play 151 When wound up, a tension can form that affects the rear cover. 110 and the display field 120 deformed in upward and downward directions, and applied to it. In this case, the multiple openings can 111 the rear cover 110 in the upward and downward directions of the rear cover 110 extend and increase the length of the rear cover 110 It can also be flexibly modified. While the rear cover is being wound up. 110 and the display field can therefore have multiple openings 111 the rear cover 110 a difference in length between the rear cover 110 and the display field 120 to compensate for a difference in the radius of curvature. During the winding of the rear cover. 110 and the display field 120 Furthermore, the multiple openings can 111 be deformed to fit the display field 120 from the rear cover 110 to reduce applied tension.

[0102] As in Fig. 7A and Fig. As shown in 7B, the multiple openings can be 111 to the several openings 111 be offset from adjacent rows. The multiple openings 111 a series can, for example, refer to the multiple openings. 111 The centers of several openings may be offset from those of adjacent rows. In particular, the centers of multiple openings may be offset. 111 in odd-numbered rows from the centers of the multiple openings 111 in even-numbered rows by no less than, for example, 1 / 2 of the width 111WR (see e.g. Fig. 7B) of each opening 111 be staggered in a row direction. The placement and arrangement of the multiple openings. 111 are in Fig. 7A is shown only as an example and is not limited to it.

[0103] Since the multiple openings 111 in a series with regard to the openings 111 They can be offset in an adjacent row, a distance can 111 WB (see e.g. Fig. 7B) between the two adjacent openings 111 , where their centers are aligned in the column direction, are reduced or minimized. In particular, in the flexible areas MA an area between the several openings 111 whose centers are aligned in the direction of the gap, exhibit stiffness. Furthermore, during the winding of the rear cover 110 the rear cover 110 be bent in the direction of the slit. If the length 111WB the section between two adjacent openings 111 As the number of centers aligned in the column direction increases, it can consequently become more difficult to remove the rear cover. 110 to bend in the direction of the gap. Since in this case there are several openings 111 the distance can be offset from row to row 111 WB between the several openings 111 , whose centers are aligned in the slit direction, are reduced or minimized compared to an arrangement in which the openings 111 are not staggered from row to row. The area between the multiple openings 111 The distance can also be reduced or minimized. 111WB between the several openings 111 , whose centers are aligned in the column direction, can decrease and the flexible areas MA can be continuously extended in the slit direction to remove or reduce the area in which the multiple openings are located. 111 are not arranged. Since the length 111WB the area between the several openings 111 By reducing or minimizing stiffness in the gap direction, the overall stiffness of the rear cover can also be affected. 110 without interfering with the winding or unwinding of the rear cover 110 can be improved.

[0104] As in Fig. As shown in 7B, the maximum width can be 111 WR the multiple openings 111 in the row direction be larger than the maximum width 111 WC in the column direction. That is, as in Fig. As shown in 7B, the maximum width can be 111 WR the multiple openings 111 in a transverse or row direction greater than the maximum width 111 WC the multiple openings 111 in the vertical or column direction.

[0105] If the width 111 WR the multiple openings 111 As the number of rows increases, it may become easier for the flexible area to function. MA the rear cover 110 It is flexibly deformed. In particular, this can occur during the winding of the rear cover. 110 the rear cover 110 bent in the direction of the gap and tension can be applied to the multiple openings 111 to extend in the column direction. If, in this case, the width 111 WR the multiple openings 111 in the row direction increases when the multiple openings 111 If the column width is stretched in the direction of the slit, it can be increased. 111 WC the multiple openings 111 to increase in size. If the multiple openings 111 Furthermore, by expanding in the column direction, the stress applied to the flexible areas MA can be reduced. By increasing the row direction width 111 WR the multiple openings 111 Therefore, the flexible areas can MA the rear cover 1110 They can be wound or unwound more easily and are designed for flexible areas. MA The applied tension can be reduced.

[0106] If the column direction width 111 WC with multiple openings 111 As the number of openings increases, they can increase. 111 They are easier to form. However, if the slit direction width 111 WC the multiple openings 111 As the opening ratio of the multiple openings increases, it can change. 111 in the flexible areas MA increase. A contact surface between the display field 120 and the rear cover 110 , which are located in the flexible areas MA If they are attached, they can also be removed. If, in this case, there is an overlap area between the display field... 120 and the rear cover 110 , i.e., a contact area between the rear cover 110 and the second adhesive layer AD2 , decreases, the rear cover can 110 from the second adhesive layer AD2 They can be separated. Therefore, the column direction width can be adjusted. 111WC the multiple openings 111 so that the adhesive strength between the display field 120 and the rear cover 110 It is controlled to suppress or prevent separation between them. Furthermore, the row direction width can be adjusted. 111 WR of multiple openings 111 be controlled in such a way that the rear cover 110 can exhibit a high degree of flexibility.

[0107] In this case, the multiple openings can 111 in the flexible area MA, but not in the first support area PA1 or in the second support area PA2 be formed. That means the first mounting holes. AH1 and the second mounting holes AH2 can in the first support area PA1 or in the second support area PA2 be trained. The multiple openings 111 , which are in the flexible sector MA are trained, but are not in the first support area PA1 or in the second support area PA2 trained. Furthermore, the first mounting holes can be AH1 and the second mounting holes AH2 in the form of the multiple openings 111 They may be different. The first support area PA1 and the second support area PA2 can be found at the header 164 or the role 151 be attached. Consequently, the first support area can be PA1 and the second support area PA2 exhibit higher stiffness than the flexible area MA Especially since the first support area PA1 and the second support area PA2 exhibiting higher stiffness, the first support area PA1 and the second support area PA2 securely attached to the header 164 or the role 151 be attached. Therefore, the display unit DP can be attached to the roller. 151 and the header 164 of the movement part MP be attached and can move in and out of the housing part HP move according to an activation of the moving part MP.

[0108] In the display device 100 According to an exemplary embodiment of the present disclosure, the rear cover can 110 with the multiple openings 111 on the rear surface of the display panel 120 be arranged to display the display field 120 to support and protect. The rear cover 110 It can be made of a metal material and can therefore exhibit rigidity. Furthermore, the flexible area can... MA the rear cover 110 , in which the display field 120 is arranged to have several openings 111 include and the rear cover 110 Consequently, it can exhibit improved flexibility. Therefore, in the fully unwound state, in which the display part DP the display device 100 outside the housing part HP The rear cover is presented. 110 , which is made of a rigid material and has high stiffness, the display field 120 Support it so that it is spread out flat. In the fully wound state, in which the display part DP the display device 100 within the housing part HP On the other hand, the rear cover can be removed. 110 with high flexibility due to the multiple openings 111 to play 151 be wound up and together with the display field 120 to be included in the HP housing section.

[0109] In the display device 100 According to an exemplary embodiment of the present disclosure, the row direction width can also be 111 WR the multiple openings 111 be controlled in such a way that the rear cover 110 It can exhibit flexibility. Furthermore, the rear cover can be adjusted. 110 The tension applied during a winding process can be reduced. In particular, this can occur during the winding of the rear cover. 110 and the display field 120 to play 151 the rear cover 110 bent in the direction of the gap and tension can be applied to the multiple openings 111 to extend in the direction of the gap. Since the multiple openings 111 a relatively large row width 111 WR The multiple openings can be observed. 111 more easily in the direction of the gaps while winding up the rear cover 110 and the display field 120 to play 151 expand, thereby affecting the rear cover 110 The applied voltage is reduced. Therefore, in the display device 100 according to an exemplary embodiment of the present disclosure by controlling the row direction width 111 WR of multiple openings 111 the flexibility of the rear cover 110 to be improved and the rear cover 110 and the display field 120 can more easily turn the role 151 to be wound up. Since the multiple openings 111 can reduce the voltage applied to the rear cover 110 and the display field 120 Furthermore, damage to the display field can occur when the material is applied while expanding in the direction of the column. 120 be suppressed.

[0110] In the display device 100 According to an exemplary embodiment of the present disclosure, the column direction width can also be 111WC the multiple openings 111 to be controlled to ensure the adhesive strength between the rear cover 110 and the display field 120 to control. In particular, the display field can be controlled. 120 on the flexible area MA of the rear cover 110 be fixed. In this case, if the opening ratio of the multiple openings 111 in the flexible area MA As it increases, a contact area between the display field is created. 120 and the rear cover 110 off. Consequently, the adhesive strength between the display field can be reduced. 120 and the rear cover 110 remove. In the display device 100 However, according to one exemplary embodiment of the present disclosure, the multiple openings can 111 in the rear cover 110 a relatively small slit direction width 111 WC. Consequently, the opening ratio of the multiple openings can vary. 111 be reduced and the contact area between the display field 120 and the rear cover 110 can be increased. If the contact area between the display field 120 and the rear cover 110 as the adhesive strength increases between the display field 120 and the rear cover 110 can be improved. Therefore, the display device can be improved. 100 according to an exemplary embodiment of the present disclosure by controlling the column direction width 111 WC with multiple openings 111 the adhesive strength between the rear cover 110 and the display field 120 to be kept at a certain level or higher in order to suppress the separation between them.

[0111] Furthermore, the row width of the multiple openings can be adjusted. 111 be larger than the slit direction width and the shape of the multiple openings 111 is not on the in Fig. 7A and Fig. The example shape shown in 7B is limited. The multiple openings 111 They can have various shapes, such as a dumbbell shape, a diamond shape, a band shape, an oval shape, or other similar shapes.

[0112] As in Fig. As shown in 7A, the flexible area MA the rear cover 110 a first flexible area MA1 between the first support area PA1 and the fastening area FA and a second flexible area MA2 between the fastening area FA and the second support area PA2 include. The first flexible area MA1 can deviate from the mounting area FA to the top of the rear cover 110 extend. In the first flexible area MA1 can the multiple openings 111 be arranged. The display field 120 can be found in the first flexible area MA1 be attached.

[0113] The second flexible area MA2 can be an area extending from the FA mounting area to the lower side of the rear cover 110 extends. In the second flexible area MA2 can the multiple openings 111 be arranged, but the display field 120 is not arranged. The second flexible area MA2 can extend to allow the active area AA of the display field 120 The HP part is presented outside the housing. For example, if the rear cover 110 and the display field 120 are in the fully unwound state, an area that is separated from the second support area PA2 the rear cover 110 , who played the role 151 is attached, up to the attachment area FA , where the flexible films 130 and the printed circuit boards 140 are attached, it is sufficient within the housing part HP be arranged. At the same time, an area that extends from the first flexible area can be... MAI , where the display field 120 is attached, up to the first support area PA1 It is sufficient to be presented outside the HP housing section.
