Abstract: An embodiment described herein includes a method for input channel voting. The method includes steps for sorting the three input values by magnitude into a high input value, a middle input value, and a low input value. The three input values are then tested. The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.

Abstract: The present invention relates to efficient organic light emitting devices (OLEDs). The devices employ three emissive sub-elements, typically emitting red, green and blue, to sufficiently cover the visible spectrum. Thus, the devices may be white-emitting OLEDs, or WOLEDs. Each sub-element comprises at least one organic layer which is an emissive layer—i.e., the layer is capable of emitting light when a voltage is applied across the stacked device. The sub-elements are vertically stacked and are separated by charge generating layers. The charge-generating layers are layers that inject charge carriers into the adjacent layer(s) but do not have a direct external connection.

The antenna traces may then be electroplated.

Abstract: A method for forming an electronic device such as a passive color OLED display. Bottom electrodes are patterned onto a substrate in rows. Raised posts formed by photoresist are patterned into columns oriented orthogonally to the bottom row electrodes. One or more organic layers, such as R, G, B organic emissive layers are patterned over the raised posts and bottom electrodes using organic vapor jet printing (OVJP). An upper electrode layer is applied over the entire device and forms electrically isolated columnar electrodes due to discontinuities in the upper electrode layer created by the raised columnar posts. This permits patterning of the upper electrodes over the organic layers without using photolithography. A device formed by this method is also described.
