As shown in <FIG>, in one embodiment, a sliding flexible display device <NUM> comprises a flexible display panel <NUM> and a sliding component <NUM> configured to carry the flexible display panel <NUM>. The sliding component <NUM> comprises a first sliding module <NUM>, a second sliding module <NUM>, and a third sliding module <NUM>. The first sliding module <NUM> and the second sliding module <NUM> are slidably connected, and the second sliding module <NUM> and the third sliding module <NUM> are slidably connected. It should be noted that, in this embodiment, through providing the sliding component <NUM> and making use of a relative sliding relationship between the three sliding modules, a transition of the sliding flexible display device <NUM> from a flat state to a retracted state and a folded state is achieved. In a process of retraction and folding, the flexible display panel <NUM> bends, and fully gives play to ultimate flexibility of the flexible display panel <NUM>. Moreover, dynamic continuity of a display screen of the sliding flexible display device <NUM> and user experience are greatly improved.

When the sliding flexible display device <NUM> is in the flat state, the second sliding module <NUM> and the first sliding module <NUM> are adjacent and arranged in parallel. The third sliding module <NUM> and the second sliding module <NUM> are adjacent and arranged in parallel, and the flexible display panel <NUM> is flattened and disposed on a flat surface formed by the plurality of sliding modules. At this time, the sliding flexible display device <NUM> has the largest display area so as to provide a better visual display effect.

When the sliding flexible display device <NUM> is in the retracted state, the second sliding module <NUM> slides gradually toward a back side of the first sliding module <NUM>, the third sliding module <NUM> gradually slides to between the first sliding module <NUM> and the second sliding module <NUM>, an area of the flexible display panel <NUM> corresponding to the first sliding module <NUM> is fixed relative to the first sliding module <NUM>, areas of the flexible display panel <NUM> corresponding to the second sliding module <NUM> and the third sliding module <NUM> are gradually recovered to the back side of the first sliding module <NUM> in a retracting process. During retracting of the sliding flexible display device <NUM>, its display area is gradually decreased, and space occupied by itself is also gradually decreased.

When the sliding flexible display device <NUM> is in the folded state, the third sliding module <NUM> is between the first sliding module <NUM> and the second sliding module <NUM>, the area of the flexible display panel <NUM> corresponding to the first sliding module <NUM> is fixed relative to the first sliding module <NUM>, and the areas of the flexible display panel <NUM> corresponding to the second sliding module <NUM> and the third sliding module <NUM> are folded between the first sliding module <NUM> and the third sliding module <NUM>. At this time, the display area of the sliding flexible display device <NUM> reaches a minimum, and only an area of the flexible display panel above the first sliding module <NUM> performs a display function. Space occupied by the entire sliding flexible display device <NUM> reaches a minimum, and a portable feature is realized.

The second protective layer <NUM> is detachable relative to a carrying surface of the second sliding module <NUM> and a carrying surface of the third sliding module <NUM>, so that in the retracted and folded state of the sliding flexible display device <NUM>, the second protective layer <NUM> exerts its protective effect as the flexible display panel <NUM> is bent.

Optionally, the protective layer <NUM> is a band-shaped layer disposed along both ends of the sliding component <NUM>, or is a layer covering an entire surface of the sliding component <NUM>. It should be understood that, when the protective layer <NUM> is the band-shaped layer, the flexible display panel <NUM> is lifted by the protective layer <NUM> and does not directly contact the sliding component, and thus the protective layer <NUM> achieves its protective effect, while consumables of the protective layer <NUM> are reduced. When the protective layer <NUM> is a full-face layer, the flexible display panel <NUM> and the sliding component <NUM> surface may be completely separated to provide comprehensive protection for the flexible display panel <NUM>.

It should be noted that, when the sliding flexible display device <NUM> is in the flat state, the elastic member <NUM> pulls the clamping slot <NUM> tightly against the side of the second sliding module <NUM>. During retracting or folding of the sliding flexible display device <NUM>, the third sliding module <NUM> is passed between the clamping slot <NUM> and the second sliding module <NUM>, and the elastic member <NUM> forces the clamping slot <NUM> to always be parallel to an edge of the second sliding module <NUM> and closely adhere to an edge of the third sliding module <NUM>.

Optionally, the first sliding module <NUM> and the second sliding module <NUM> are connected by a first slidably connecting rod <NUM>, and the first sliding module <NUM> is disposed with a first sliding path <NUM>.
