Abstract
(EN)
Disclosed by the present invention are a flexible display panel, a flexible display apparatus and a preparation method for a flexible display panel: by means of a metal trace segment of a portion of a bending area of a flexible display panel being a dual-layer structure, and a second metal layer trace employing a wave-like trace design, the amount of stress received by the metal trace during a bending process may be reduced, thereby lessening the probability of a metal trace in a bending area of a flexible display breaking, and ensuring that the resistance of the metal trace is stable; and a connection portion of a first metal layer trace and the second metal layer trace may have improved reliability, thus lessening the probability of display abnormalities due to trace breakage, and ensuring that signal transmission is normal.

La présente invention concerne un panneau d'affichage souple, un appareil d'affichage souple et un procédé de préparation d'un panneau d'affichage souple : au moyen d'un segment de trace métallique d'une partie d'une zone de courbure d'un panneau d'affichage souple qui est une structure à double couche, et une seconde trace de couche métallique utilisant une conception de trace de type onde, la quantité de contrainte reçue par la trace métallique pendant un processus de courbure peut être réduite, ce qui permet de réduire la probabilité de rupture d'une trace métallique dans une zone de courbure d'un dispositif d'affichage souple, et d'assurer que la résistance de la trace métallique est stable; et une partie de connexion d'une première trace de couche métallique et de la seconde trace de couche métallique peut avoir une fiabilité améliorée, réduisant ainsi la probabilité d'anomalies d'affichage dues à une rupture de trace, et garantissant que la transmission de signal est normale.
