Title
(EN) METHOD FOR MANUFACTURING FLEXIBLE ARRAY SUBSTRATE
(FR) PROCÉDÉ DE FABRICATION DE SUBSTRAT DE RÉSEAU SOUPLE
(ZH) 柔性阵列基板的制作方法
Abstract
(EN) Disclosed is a method for manufacturing a flexible array substrate. The method comprises: first attaching a flexible substrate (3) to a rigid support plate (1) to manufacture a back drive circuit (4) and manufacturing, on the back drive circuit (4), a protective layer (5); then, after tearing off and turning over the flexible substrate (3), re-attaching same to the rigid support plate (1), so that the protective layer (5) comes into contact with an adhesive layer (2); and then forming a via hole (6) in the flexible substrate (3) to manufacture a front drive circuit (7) and a display circuit, wherein the front drive circuit (7) is electrically connected to the display circuit, and the back drive circuit (4) is electrically connected to the display circuit by means of the via hole (6), thus manufacturing a flexible array substrate with circuit structures on two sides. By means of distributing circuit structures in a non-display region to two sides of the flexible substrate (3), the width of the non-display region can be reduced, thereby realising ultra-narrow border or borderless display.
(FR) La présente invention concerne un procédé de fabrication d'un substrat de réseau souple. Le procédé comprend les étapes qui consistent : à fixer tout d'abord un substrat souple (3) à une plaque support rigide (1) pour fabriquer un circuit de commande arrière (4), et à fabriquer une couche de protection (5) sur le circuit de commande arrière (4) ; puis, après retrait et retournement du substrat souple (3), à le fixer à nouveau à la plaque support rigide (1), de sorte que la couche de protection (5) entre en contact avec une couche adhésive (2) ; et à pratiquer ensuite un trou d'interconnexion (6) dans le substrat souple (3) pour fabriquer un circuit de commande avant (7) et un circuit d'affichage, le circuit de commande avant (7) étant connecté électriquement au circuit d'affichage, et le circuit de commande arrière (4) étant connecté électriquement au circuit d'affichage au moyen du trou d'interconnexion (6), ce qui permet de fabriquer un substrat de réseau souple avec des structures de circuit sur deux côtés. Grâce à la distribution de structures de circuit dans une région de non-affichage sur deux côtés du substrat souple (3), la largeur de la région de non-affichage peut être réduite, ce qui permet de réaliser un écran ayant une bordure extrêmement étroite ou n'ayant aucune bordure.
