MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202617013245 A) filed by Hkc Corporation Limited, Shenzhen, China, on Feb. 6, for 'display panel and preparation method therefor.'
Inventor(s) include Feng, Yajuan; Yi, Wenyu; Wei, Dongmei; Chen, Jie; Cao, Zhonglin; Wu, Chuan; and Ye, Lidan.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "A display panel (100) and a preparation method therefor. The preparation method comprises: providing an array substrate (10); coating a first electrode pattern layer (13) with an active group material, to form a bonding layer (21); placing the array substrate (10) in a reaction solution (40) containing a light-emitting material, so that the light-emitting material is attached to the bonding layer (21), to form a light-emitting layer (22); and manufacturing a second electrode pattern layer (23) on the light-emitting layer (22). The active group material has a first functional group (21a), and the light-emitting material has a second functional group (22b) and third functional groups (22c). In a reaction stage, the second functional group (22b) and the first functional group (21a) undergo a graft copolymerization reaction, so that the light-emitting material is attached to the bonding layer (21), and a third functional group (22c) and a third functional group (22c) undergo a polymerization reaction, to form a light-emitting layer (22) having a preset thickness (d). According to the preparation method, evaporation is not needed, the production costs can be reduced, and the utilization rate of the light-emitting material is increased."
The patent application was internationally filed on Aug. 30, 2024, under International application No.PCT/CN2024/115909.
