Glass: Electronics / Display

Display technology is manufactured in places like China. BOLD TM is helping clients develop new products leveraging thin glass materials to find new emerging display applications such as automotive dashboards that can be manufactured in the United States, Canada, South America and Europe.  In many cases, BOLD TM facilitating an opening door, by leveraging thin glass vendors who are proactively seeking to supply thin, light and strong glass to various markets, including electronics, architectural, automotive, and solar applications.  BOLD TM has adopted the same philosophy – help our clients achieve their product development goals, by supplying flexible and cost-effective automation through laser-based thin glass laser cutting, drilling, and thin film patterning processes.

Laser Glass Cutting

Within the marketplace, there is a multitude of laser-based glass cutting processes, the question is which do you choose?  BOLD TM offers its assistance when working with clients.  In many cases, the final process might be a combination of techniques to ensure process quality, repeatability and accuracy.   BOLD TM offers various options including such techniques as, Filamentation and Direct Ablation. For product information Contact BOLD

Laser Glass Drilling

When it comes to glass drilling, the reality is releasing small features within the glass sheet, such as speaker holes or mounting features, are limited to thin glass materials, such as thickness ranges from 0.5 to 1.1 mm, with hole diameters down to 3 to 4 mm.  For larger holes with glass thickness >1.1 mm, there are other techniques, such as Laser Ablation.  In terms of microelectronic applications, through via holes can be made to a diameter of <35 microns.

Glass Thin Film Patterning

Thin films are very useful for glass applications where the glass substrate is part of a system that needs to perform a specific function.  Applications for automotive glass heaters and IR reflective coating are common, biomedical devices where the thin film provides a means to conduct diagnostic tests and in architecture next generation smart windows which trigger a shading or solar energy functions.   In these cases, the thin film might need to be patterned or edge deleted.  BOLD TM has developed a number of systems for this type of application including 3D robotic edge deletion for windshields and linear patterning systems for touchscreen displays.  Coatings that can be patterned are numerous, however the most common are TCO "Thin Conductive Oxides", Graphene, ITO, Metals and Multi-layered dielectric coatings which can consist of different coatings, such as metals.
