Abstract

The invention relates to a flexible OLED substrate structure and design method. The flexible OLED substrate structure includes a first inorganic layer that requires conduction, and a plurality of via holes are provided on the first inorganic layer where conduction is required to conduct conduction and adjust the pattern density of the inorganic layer. The design method of the flexible OLED substrate structure at least includes: 1. Designing multiple via holes on the inorganic layer where there is a need for conduction; 2. Using a mesh design for the metal layer power supply wiring; 3. Perpendicular to the bending axis Or the signal routing of the winding shaft adopts a serpentine design. The flexible OLED substrate structure and design method of the present invention can increase the foldable times of the flexible OLED, reduce the bending radius, and improve the bendable performance; increase the curlable times of the flexible OLED, reduce the curling radius, and improve the rollable performance.

Description

technical field [0001] The invention relates to the field of active displays, in particular to a flexible OLED substrate structure and design method. Background technique [0002] OLED is a display technology with great development prospects. It not only has excellent display performance, but also has the characteristics of self-illumination, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display. Known as the "dream display", it has been favored by major display manufacturers and has become the main force of the third-generation display devices in the field of display technology. OLED displays generally include: a substrate, an anode on the substrate, an organic light-emitting layer on the anode, an electron transport layer on the organic light-emitting layer, and a cathode on the electron transport layer. The materials mainly include Inorganic layer, organic layer and metal layer, etc. [0003] With the development of ...
