A nozzle assembly with a nozzle body cooperating with a flexible portion, the nozzle assembly also contains a throttle plate, and this combination is used to mitigate pressure variations transmitted to the nozzle assembly. The combination results in a more uniform liquid deposition during continuous liquid printing.

Pressure wave damper apparatus for continuous liquid printing

A liquid replenishment system includes a dispensing vessel for holding a supply of a liquid that has an outer can and corresponding lid conjoinable to the outer can in an air-tight manner. The dispensing vessel is improved by the provision of a separate self-supporting secondary inner container removably receivable within the outer can. The container is fabricated of a material that is non-reactive with a liquid composition containing an organic semiconductor material, such as a polytetrafluoroethylene material or stainless steel.

Liquid replenishment system for a printing apparatus for depositing a liquid composition on a backplane including a dispensing vessel having a self-supporting secondary container

A liquid replenishment system for a printing apparatus that includes a dispensing nozzle and a supply reservoir is improved by a replenishment system having a volume control network responsive to a signal representative of the volume of liquid within the reservoir for generating a volume control signal. The volume control signal is applied to a pump operable to inject replenishment liquid from a replenishment source into the reservoir. The replenishment liquid is injected at a pressure at least substantially equal to the pressure in the reservoir and at a flow rate selectable in accordance with the volume control signal such that the volume of liquid in the reservoir is maintained at a predetermined reference level. A temperature control network for adjusting the temperature of the replenishment liquid to a temperature that lies within a predetermined range of the temperature of the liquid in the reservoir may also be provided.

System and process for liquid replenishment for a printing apparatus for depositing a liquid composition on a backplane

An apparatus and method for liquid-phase dispensing of layers onto a substrate of an electronic device. An absorbent material reduces or eliminates splatter of printing material on the substrate during continuous printing operations. The absorbent material can be regenerated by exposure of new surface area or vacuum drawing of printing material through the absorbent material.

Apparatus and method for preventing splatter for continuous printing

Provided are methods for conditioning a getter material, comprising subjecting the getter material to microwave radiation. Electronic devices uses the conditioned getter materials and methods of making such electronic devices are also provided.

Methods of conditioning getter materials

Methods and devices are provided for improving the encapsulation processes for an organic electronic device.

Encapsulation tool and methods

The invention is directed to a screen-printable getter composition comprising: (a) glass frit; dispersed in (b) organic medium. The invention is further directed to a screen-printable thick film getter composition comprising: (a) glass frit; and (b) desiccant material; dispersed in (c) organic medium. The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO, 0-80% BO, 0-90% BiO, 0-90% PbO, 0-90% PO, 0-60% LiO, 0-30% AlO, 0-10% KO, 0-10% NaO, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure.
