Abstract
(EN)
A display panel (10) and a method for detecting a crack thereof. The display panel (10) comprises a panel body (11), a grounding wire (12), a first grounding connection portion (13), a first test connection portion (14), a second grounding connection portion (15), and a second test connection portion (16), and a switch portion (17). The grounding wire (12) surrounds a display region (11a). The first grounding connection portion (13) and the first test connection portion (14) are connected in parallel to one end of the grounding wire (12). The second grounding connection portion (15) and the second test connection portion (16) are connected in parallel to the other end of the grounding wire (12). The switch portion (17) is electrically connected between the first grounding connection portion (13) and the grounding wire (12).

L'invention concerne un panneau d'affichage (10) et son procédé de détection de fissures. Le panneau d'affichage (10) comprend un corps de panneau (11), un fil de mise à la masse (12), une première partie de connexion de mise à la masse (13), une première partie de connexion de vérification (14), une seconde partie de connexion de mise à la masse (15), et une seconde partie de connexion de vérification (16), et une partie de commutation (17). Le fil de mise à la masse (12) entoure une région d'affichage (11a). La première partie de connexion de mise à la masse (13) et la première partie de connexion de vérification (14) sont connectées en parallèle à une extrémité du fil de mise à la masse (12). La seconde partie de connexion de mise à la masse (15) et la seconde partie de connexion de vérification (16) sont connectées en parallèle à l'autre extrémité du fil de mise à la masse (12). La partie de commutation (17) est connectée électriquement entre la première partie de connexion de mise à la masse (13) et le fil de mise à la masse (12).
