- the lateral sliding support plate 132 Rotating connection with the rotation support plate 133, rotatable connection between the rotation support plate 133 and the screen body fixed support plate 134, sliding of the side slide support plate 132 in the chute in the fixing member 14, when the flexible display body is unfolded shape In the folded state, the first support component 21 and the second support component 22 are folded in opposite directions at the same time, that is, the first support component 21 and the second support component 22 are folded in half. Since the first support component 21 and the second support component 22 The folding direction is opposite.
- the first driving component 101 drives the first supporting component 21 to rotate away from the first driving component 101
- the second driving component 102 drives the second supporting component 22 to rotate relatively and away from the second driving component 102. Therefore, the first support The component 21 and the second supporting component 22 are separated from each other, and provide more accommodation space for the bent portion of the flexible display body. Therefore, during the folding process of the flexible display device, the occurrence of creases in the bent portion of the flexible display body is avoided. Problems that invalidate the display body.
- the second driving component 102 driving the second supporting component 22 to rotate relatively and away from the second driving component 102 is as described above. I will not repeat them here.
- the first support component 21, the second support component 22, and two driving components are located below the flexible display body and support and fix the first portion, the second portion, and the flexible display body together.
- the bent part is shown in FIG. 7.
- the first supporting component 21 is far from the second supporting component 22, and the folded structure of the flexible display device is shown in FIG. 8.
- the flexible display body in the embodiment provided by the present application may further include a circuit board, and the circuit board is disposed inside the support assembly 2.
- the circuit board is used to provide a driving circuit required for the flexible display body. It should be understood that the embodiments of the present application may choose to set the circuit board at different positions according to the requirements of the actual application scenario (such as the internal capacity of the supporting component, etc.), and this application does not limit the position of the circuit board.
- the circuit board may be a flexible circuit board. Since the flexible circuit board has a bending performance, the circuit board in this embodiment may be disposed at the driving component.
- the flexible display body in the embodiment provided by the present application may further include a battery, and the battery is disposed inside the support assembly 2.
- the battery is used to provide the power required by the circuit board. It should be understood that the embodiments of the present application may choose to set the battery at different positions according to the requirements of the actual application scenario (such as the internal capacity of the support component 2), and the application does not limit the position of the battery.
- the battery may be a flexible battery. Since the flexible battery has a bending performance, the battery in this embodiment may be disposed at the driving component. Therefore, although the present application has been described with reference to specific examples, which are intended to be illustrative only, and not to limit the present application, it will be apparent to one of ordinary skill in the art that Based on the spirit and scope of the application, the disclosed embodiments can be changed, added or deleted.
