一种基于飞秒激光诱导双向波纹结构丰富信息显示的方法
By performing two metal film depositions and laser induction on a glass substrate, a bidirectional corrugated structure with different included angles is formed, which solves the problem of limited structural color display range in the prior art and realizes the display of synthetic colors other than rainbow colors and information display in multiple modes.

AI Technical Summary
In existing technologies, femtosecond laser-induced periodic surface structures can only produce structural colors ranging from red to purple, which limits the display range and application scenarios of structural colors. Furthermore, structural colors can only be obtained in reflection mode on the surface of metal blocks, thus limiting the information display range.
By performing two depositions of metal films and laser induction on a glass substrate, a metal film is first deposited on the surface of a unidirectional corrugated structure and then laser induction is performed. Subsequently, a second deposition and laser induction are performed on the surface of the unidirectional corrugated structure to form a bidirectional corrugated structure with different included angles.
It expands the display range of structural colors, enables the display of synthetic colors other than rainbow colors, and can acquire structural colors in both reflection and transmission modes, thus enriching the choices and application scenarios for information display.
