The stylus 28 is disposed in the receiving hole 25, so that the stylus 28 is prevented from being lost.
In the present embodiment, the size of the second display portion 12 is smaller than the size of the first display portion 10. The area that panel support piece 2 did not set up flexible display screen 1 forms and dodges district 27, it is provided with camera subassembly, interface and function button, earphone and microphone in the district 27 to dodge. The escape area 27 may be provided at any position of the edge of the panel support 2, for example, the upper edge, the lower edge, the left edge or the right edge. Wherein, depending on the user's habits, and in view of appearance considerations, the escape area 27 is located near the extreme edge of the panel support 2 as shown. Thus, the folding is not affected by the arrangement of the avoiding area 27, the avoiding area 27 is only arranged on one side of the second supporting surface 22 in the display area, and other edges can be processed by narrow frames, so that the appearance effect can be improved. Some parts of the folding terminal that can be seen from the outside can also be disposed in the avoiding area 27, for example, in the case of a mobile phone, it is often necessary to provide keys 101 such as a power-on key and a volume key, and an interface for charging, etc., and as shown in fig. 2, the keys 101 can be disposed on the other side surface opposite to the side supporting surface 24. In other embodiments, a volume key may be further provided at the bent portion 14, so that the volume can be adjusted by touching.
In order to fix the second display portion 12 to the second supporting surface 22 of the panel supporting member 2 after being folded, a locking mechanism (not shown) is disposed on each of the second display portion 12 and the second supporting surface 22, and the locking mechanism is used for fixing the relative position of the second display portion 12 after the second display portion 12 is folded. Locking mechanism can have multiple implementation, for example, the joint structure, magnetism inhale structure or magic subsides etc. can conveniently fix and the connected mode of separation.
In addition, the first display portion 10, the second display portion 12 and the bending portion 14 can be independently controlled by a system main board, that is, in a folded state, the system main board can only selectively control the first display portion 10, the second display portion 12 and the bending portion 14 to realize their respective display functions. In the unfolded state, the system motherboard controls the first display portion 10, the second display portion 12 and the bending portion 14 to form a full screen, and the three display screens together.
In this embodiment, in order to switch the flexible display panel 1 between the folded state and the unfolded state, a deformation layer may be disposed in a region where the folding portion 14 is located, and the deformation layer is made of Shape Memory Alloy (SMA). Shape memory alloys are materials composed of two or more metal elements that exhibit a Shape Memory Effect (SME) through thermoelastic and martensitic transformation and their inversions. The shape memory alloy deforms at a relatively low temperature and can recover the shape before deformation after heating.
