AI Technical Summary
Technical Problem
Existing technologies struggle to achieve high pixel density and ultra-high resolution in small-sized display devices while avoiding reliability issues.
Method used
The design employs a cross-repetitive planar and tower-like region structure, combined with a suspended structure of metal and insulating dikes, to form light-emitting elements through deposition and photopatterning processes, avoiding the use of fine metal masks.
Benefits of technology
It achieves a high pixel integration and ultra-high resolution display with over 1500 pixels per inch, and has no reliability defects, making it suitable for small-sized display devices.
