Abstract:

The ink jet printing technique can be an alternative fabrication route for LCD color filters. The source of luminance nonuniformity in color filters fabricated by ink jet printing is described and methods to minimize this nonuniformity are presented. Both drop volume uniformity of the ink jet printhead and morphology of the printed color filter layer are important to achieve required luminance uniformity. Some practical methods to control the drop volume uniformity were tested and proposed. Morphological control of the printed color filter was also studied. Desirable interfacial energy between color filter and black matrix was modeled and tested using both plasma treatment and solution treatment.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
