Displaycia is dedicated to the open-access approach to publishing. Our belief is that this approach offers the best conditions and opportunities for research to achieve a meaningful impact within the academic community. We ensure that readers will not face any pay-per-view fees when accessing the articles published in our journals. This approach facilitates unrestricted online access to research findings and enhances the visibility of published articles. The article publication charge (APC) is a financial obligation required from authors to facilitate the open access availability of their research. The open-access journals we offer implement an Article Processing Charge to address the costs incurred during the publication process, which includes overseeing peer review to copy editing and the hosting of the final article on dedicated servers. This fee may be covered by the author or by the funding body supporting their research. Authors are not required to make any payments when submitting their manuscripts to our journal. Once the paper has been accepted for publication and the authors opt to publish their work in our journals, in that case, APC is required. This fee is applicable regardless of the number of authors or pages and is payable only after an article has been accepted.
