Problems solved by technology

Polyimide has excellent heat resistance, radiation resistance, chemical resistance, electrical insulation, mechanical properties, etc., but its ability to block water and oxygen is average, and the ability of flexible polyimide substrates to block water and oxygen is usually the main one. It is by depositing a multi-layer stacked inorganic film on the surface of a flexible substrate, or using a multi-layer polyimide / inorganic film alternately stacked structure, but there are problems such as cumbersome process, increased internal stress, stress concentration, and inorganic layer fracture.

Abstract

An embodiment of the invention discloses a flexible film and a making method thereof, a display panel and electronic equipment. The making method of the flexible film includes: providing a lining substrate; preparing a precursor, homogeneous solution and silver components into a homogeneous solution by mixing and evenly coating the homogeneous solution on the lining substrate; performing high-temperature heat imidization reaction in high purity hydrogen to form a polyimide-silver composite film on the lining substrate to meet requirements of heat resistance, flexibility, high resistance to water and oxygen, high luminous efficiency and the like. The flexible film can be implemented by applying a polyimide-silver composite film display panel or electronic equipment, and good resistance to oxygen and high luminous efficiency are achieved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a method for manufacturing a flexible film, a flexible film, a display panel and an electronic device. 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 hard and brittle characteristics; 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 preferred materials for future flexible display technologies. [0003] Currently, the most promising polymer material used as a flexible substrate is polyimide (PI). Pol...
