Abstract
Official abstract text for this publication.
A method for manufacturing an organic light emitting diode (OLED) array is provided that includes applying an energizing signal to at least one of the OLED pixels in the array. The energizing signal exceeds a threshold level. The method also includes reducing the energizing signal and identifying an OLED in the array that continues to remain energized. The method further includes irradiating the identified OLED to degrade the organic material in the OLED. A method of performing quality control in a manufacturing process of an OLED array is provided. The method includes determining an intensity, a time and a wavelength of radiation sufficient to render an OLED of the OLED array inoperative by degrading organic material in the OLED. A system of performing quality control in a manufacturing process of an OLED array is provided. A computer-readable medium having stored thereon computer-executable instructions is provided.
First claim
Opening claim text (preview).
I claim: 1. A system of performing quality control in a manufacturing process of an organic light emitting diode (OLED) array comprising OLED pixels including organic material, comprising: means for applying an energizing signal to at least one of the OLED pixels, the energizing signal exceeding a threshold level below which the OLED pixel should not emit light; means for reducing the energizing signal applied to the at least one of the OLED pixels below the threshold level; m…
