The present disclosure relates to a field of display technology, and particularly to a display panel and a display terminal.
Stretchable display technology, as an important technical upgrade of flexible displays after folding technology, has an ability to deform and stretch in any direction, can effectively solve existing technical questions, such as tetrahedral, non-gaussian curved surface bonding, display area bending, etc., and has broad application prospects. In an existing stretchable display panel, in order to facilitate tensile strain, display units of the stretchable display panel are spread out in a shape of islands, and these island-shaped units are connected through ribbon-like hinge regions (bending structures), wherein pixel circuits of the stretchable display panel are distributed in the island-shaped units, and connection lines (a plurality of metal lines) between the pixel circuits are distributed on the bending structures.
When the stretchable display panel is stretched and deformed, the bending structures will be deformed by force, wherein a strain resistance of the bending structures is inversely proportional to a width of the bending structures. At present, single-layer or multi-layer titanium (Ti)/aluminum (Al)/titanium (Ti) wiring is often used for the bending structures. Same-layer wirings are placed in parallel on a same layer, and a certain distance in a horizontal direction between two adjacent of the same-layer wirings is reserved to prevent short circuit.
