Abstract

The invention relates to a flexible OLED substrate structure and the design method thereof.The flexible OLED substrate structure contains the first inorganic layer with conductive demand which has multiple via holes on positions with conductive needs for conduction and adjustment on density of the organic layer patterning.The design method of the flexible OLED substrate structure at least comprises: 1. Adopt multiple via holes on inorganic layer where needs conduction; 2. Adopt net structure on power routing of the metal layer; 3. Adopt snakelike structure on signal routing which is vertical to bent axis or flexible axis. The flexible OLED substrate structure and its design method can increase its collapsible frequency, reduce its bend radius and improve bend performance; it can also improve the flexible frequency of the substrate structure, reduce its flexible radius and improve its flexible 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 ...
