Abstract
(EN)
An antistatic display panel and a preparation method. The display panel comprises a display area, and a driving chip fixed on the surface of a flexible circuit board is bound to the lower edge of the display area. A pin on the driving chip is electrically connected to an electrostatic discharge circuit, and the pin and the electrostatic discharge circuit form a closed loop.
(FR)
L'invention concerne un panneau d'affichage antistatique et un procédé de préparation. Le panneau d'affichage comprend une zone d'affichage, et une puce d'entraînement fixée sur la surface d'une carte de circuit imprimé flexible est liée au bord inférieur de la zone d'affichage. Une broche sur la puce d'entraînement est électriquement connectée à un circuit de décharge électrostatique, et la broche et le circuit de décharge électrostatique forment une boucle fermée.
