Abstract

The invention discloses a flexible substrate and a fabrication method thereof, and a display panel. The flexible substrate comprises a first flexible layer comprising a bending area and a display area, a metal oxidation layer arranged on the display area of the first flexible layer, and a first metal layer arranged on the bending area of the first flexible layer, and the surface of the first metallayer is oxidized as the metal oxidation layer so that the flexible substrate has excellent water-oxygen blocking capability and bending resistance.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a flexible substrate, a manufacturing method thereof, and a display panel. Background technique [0002] With the rapid development of modern display technology, the field of display technology is developing towards lighter, thinner, softer and more transparent. Traditional glass substrates are difficult to meet the requirements of future flexible display technology due to their own characteristics of hardness and brittleness, while polymer film substrates have the characteristics of light weight, flexibility, and excellent comprehensive performance, which can well meet the requirements of display technology for flexibility. Therefore, flexible polymer substrate materials are the materials of choice for future flexible display technologies. [0003] At present, the most promising polymer material for flexible substrates is polyimide (PI). Polyimide has excellent heat res...
