Abstract
(EN)
A display panel (01) is provided. The display panel (01) includes a flexible substrate (10); a display sub-region (100) on the flexible substrate (10) including a light emitting device (20); a peripheral region (200) of the display sub-region (100) spacing the display sub-region (100) from an adjacent display sub-region (100); and a current compensator (30) in the peripheral region (200) for compensating a current flowing through the light emitting device (20) of the display sub-region (100) in response to deformation of the flexible substrate (10).

L'invention concerne un panneau d'affichage (01). Le panneau d'affichage (01) comprend un substrat souple (10) ; une sous-région d'affichage (100) sur le substrat souple (10) comprenant un dispositif électroluminescent (20) ; une région périphérique (200) de la sous-région d'affichage (100) créant un espace entre la sous-région d'affichage (100) et une sous-région d'affichage adjacente (100) ; et un compensateur de courant (30) dans la région périphérique (200) pour compenser un courant circulant à travers le dispositif électroluminescent (20) de la sous-région d'affichage (100) en réponse à une déformation du substrat souple (10).
