In the state shown in fig. 9, the end of the second display screen 22 away from the first display screen 21 is slid rightward to the near end (located at the end position of the first side 13 facing the second display screen side) in the first direction on the back surface 12 by the first sliding mechanism, at this time, the second display screen 22 is no longer close to the outer surface of the main body 10, but the second display screen 22 is still bent along the shape of the outer surface of the main body 10, the area of the second display screen 22 facing the front surface 11 is the largest, the display area of the display device facing the front surface direction includes the area of the first display screen 21 and the area of the second display screen 22 facing the front surface 11, and the expansion of the display area of the display device facing the front surface direction is realized.
The first state of the display device shown in fig. 8 is a state when it is stored. It is easily understood that, due to the arrangement of the second sliding mechanism 70, a hollow space exists between the flexible support sheet 32 and the main body 10 in the first state, so that the flexible support sheet 32 cannot be attached to the outer surface of the main body 10, and thus the second display screen 22 may collapse in the storage state. To avoid this, as shown in fig. 8, in the present embodiment, the display device further includes a support structure 60.
In the present embodiment, as shown in fig. 8 and 9, the support structure 60 includes a support body 61, and the support body 61 is disposed between the second slide mechanism 70 and the first slide mechanism. The first slide mechanism includes mating first and second slide members 41 and 42, and the second slide mechanism 70 may include third and fourth slide members 71 and 71.
Fig. 10a is a schematic diagram of the display device of the second embodiment facing the user side in the second state, and fig. 10b is a schematic diagram of the display device of the second embodiment facing away from the user side in the second state. As shown in fig. 10b, the first sliding member 41 is disposed on the back surface of the main body 10, the supporting body 61 is fixedly connected with the second sliding member, the third sliding member 71 is disposed on the supporting body 61, and the fourth sliding member is connected with one end of the second display screen far from the first display screen.
The first slide mechanism may include one set of the first slide member 41 and the second slide member 42, or may include a plurality of sets of the first slide member 41 and the second slide member 42. When the first sliding mechanism may include a set of the first sliding member 41 and the second sliding member 42, the first sliding mechanism may be disposed at an intermediate position of the display device along a dimension of a second direction, which is a direction perpendicular to the first direction. In one embodiment, the first slide mechanism includes two sets of first slide member 41 and second slide member 42. Two sets of first and second sliding members 41 and 42 may be provided at both ends of the rear surface of the display device in the second direction, respectively, as shown in fig. 10 b. In fig. 10b, two sets of first and second slide members 41 and 42 are provided at the upper and lower ends of the display device, respectively. When the first sliding mechanism includes more sets of the first sliding member 41 and the second sliding member 42, the sets of the first sliding member 41 and the second sliding member 42 may be disposed at regular intervals from the upper end to the lower end of the display device to ensure that the second display screen is uniformly stressed during the sliding process. In fig. 10b, the second slide mechanism 70 comprises three sets of third and fourth slide members 71, 71. The three third sliding parts 71 are uniformly spaced from the upper end to the lower end of the display device on the supporting body 61 to ensure that the second display screen is uniformly stressed during the sliding process. The fourth slide member is provided on the second display screen and corresponds to the third slide member 71. It will be readily appreciated that the second slide mechanism may be identical to the first slide mechanism.
As shown in fig. 8 and 9, the support structure may further include a filling body 62, and the filling body 62 is disposed at an end of the support body 61 facing the second display screen. The sliding of the end of the second display screen 22 away from the first display screen 21 by the first sliding mechanism and the second sliding mechanism in the direction opposite to the first direction can make the second display screen fit on the outer surface of the main body 10 through the filling body 62. In the state shown in fig. 8, the second display screen is attached to the outer surface of the main body 10 by the flexible support sheet 32 and the filling body 62. With the structure, when the display device is in the first state, the second display screen 22 and the main body 10 are no longer hollow, so that the display device is prevented from collapsing and deforming in the storage state, and the storage of the display device is facilitated.
The display device of the present embodiment, when deformed from the first state (shown in fig. 8) to the second state (shown in fig. 9), therefore, first pushes the second slide mechanism 70 rightward, and then pushes the first slide mechanism rightward to reach the state shown in fig. 9; when deforming from the second state (shown in fig. 9) to the first state (shown in fig. 8), the first slide mechanism is pulled leftward first, and then the second slide mechanism 70 is pulled leftward to reach the state shown in fig. 8.
