Ink writing head with piezoelectrically excitable membrane

Producing a glass solder seal without interfering thermal stresses in a display device containing at least two mutually parallel plates tightly connected at the edges via a frame. One plate is coated with a pattern of separately addressable electrodes which are each brought to the outsides through the frame. The method includes

Method for manufacturing a display device

A process for the manufacture of precision flat parts such as masks, templates, and the like having very small openings therein with high contour details yet with substantial material thickness utilizes a metallized glass carrier having a stencil etched thereon with a negative working photo resist laminated on it. Exposure of photo resist is achieved through the glass so that maximum intensity of light in the photo resist occurs at the juncture between the photo resist and the glass carrier for maximum adhesion. Irregularly shaped apertures can be generated by selective varied orientation of the glass carrier during the exposure.
