Abstract
(EN)
The present application provides a display panel and a manufacturing method therefor, and a display device. The manufacturing method comprises the following steps: 1) providing a pretreatment solution containing a water-soluble organic protective agent, and forming, on an anode, a solution layer covering the anode; 2) drying the solution layer to form an adhesive layer; 3) removing the adhesive layer; and 4) drying the anode, wherein the pre-treatment solution comprises, in mass percent, 10-30% of propylene glycol methyl ether and 70-90% of water. The method can effectively improve the current efficiency of the display panel and reduce the driving voltage of the display panel.

La présente invention concerne un panneau d’affichage et son procédé de fabrication, et un dispositif d’affichage. Les étapes du procédé de fabrication consistent : 1) à appliquer une solution de prétraitement contenant un agent protecteur organique soluble dans l’eau, et à former, sur une anode, une couche de solution recouvrant l’anode ; 2) à sécher la couche de solution pour former une couche adhésive ; 3) à retirer la couche adhésive ; et 4) à faire sécher l’anode, la solution de prétraitement comprenant, en pourcentage en masse, entre 10 et 30 % de méthyléther de propylène glycol et entre 70 et 90 % d’eau. Le procédé peut améliorer efficacement l’efficacité de courant du panneau d’affichage et réduire la tension d’attaque du panneau d’affichage.
