A method of encapsulating devices including providing a getter layer in the penetration path of atmospheric elements. The getter layer serves as a barrier to potentially deleterious atmospheric components, such as moisture and gases, that penetrate the device. In one embodiment, the getter layer surrounds an active region where active component or components are formed.

Encapsulation for organic devices

A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects, the adverse effect on the uniformity of the polymer layer is reduced or prevented.

Uniform deposition of organic layer

An OLED device having pillars with a cross section that is wider on the top. The pillars structure a conductive layer during deposition into distinct portions located between the pillars and on the top of the pillars. In one embodiment, the grooves between the pillars extend outside the electrode region to prevent shorting of adjacent electrodes.

Electrode patterning in OLED devices

An encapsulation for a device is disclosed. Spacer particles are randomly located in the device region to prevent a cap mounted on the substrate from contacting the active components, thereby protecting them from damage.

Encapsulation for organic LED device

An OLED device having a conductive layer patterned by pillars to form electrodes in the device is disclosed, wherein portions of the pillars have at least 2 sub-rows to prevent shorting of adjacent electrodes. In one embodiment, the ends of the pillars are split into at least 2 sub-rows.

Robust electrode patterning in OLED devices

A method of encapsulating an organic device including flash evaporating a getter layer on the substrate is disclosed. The getter layer comprises an alkaline earth metal, such as barium. The getter layer serves to protect the active components by absorbing surrounding moisture and gases.

Method of fabricating electronic devices

An OLED device having pillars with cross section that is wider on the top. The pillars structure a conductive layer during deposition into distinct portions located between the pillars and on the top of the pillars. In one embodiment, the grooves between the pillars extend outside the electrode region to prevent shorting of adjacent electrodes.

An OLED device using improved pillars to facilitate patterning of a conductive layer is described. Conventional use of pillars to pattern electrodes encounters shorting problems due to piling of polymer material at the base of the pillars. This piling deteriorates the profile of the pillars which adversely impacts the ability of the pillars to pattern the conductive layer to form the electrodes. The present invention avoids the shorting problem by separating the pillars into at least first and second sub-pillars. By providing a relatively narrow gap between the sub-pillars, the amount of polymers filling the area between the gap is small. This prevents at least the sidewalls of the pillars facing the gap from being deteriorated by polymer pile-up, thus ensuring that the conductive layer is discontinuous between the sub-pillars.
