(Lower left) A laser makes a hole in a material. (Upper left) The fluence of the laser is measured. (Lower right) Measurements of the fluence and the hole depth are superimposed. (Upper right) The relationship between these measurements is then determined so that hole depth can be calculated based solely on the fluence. (Image: Sakurai et al.)

Optimized Laser Cutting Processes and System Solutions for Separation of Ultra-Thin Glass for OLED Lighting and Display Applications

This article is brought to you by: 

For some years now, laser cutting processes based on filament technology with ultra-short pulse (USP) lasers have been increasingly adopted in industrial applications.

The main reasons for this are the good edge quality that can be achieved with simultaneous easy automation and free-form capability. This ability to be automated is of critical importance, especially for applications that target the mass market with their end products.

However, the real advantage of the technology comes from its almost unlimited free-form capability. In addition to established manufacturing processes for glasses of medium thickness from 0.2-2 mm, an increasing number of applications with ultra-thin glasses of 30-100μm are entering the market. These applications also require further development of the process and fab technology.

This article describes the possibilities of laser technology based on applications for OLED-based lighting and glass components in the display area.
