Special Issue Information

Dear Colleagues,

The fast response time of liquid crystals (LCs) has long been an important topic for both display and non-display applications. In many new advanced applications, such as VR/AR, the fast response time of liquid crystals has become an even more important and critical requirement in order to minimize problems such as motion blur, motion sickness, etc.

At present, there are many possible techniques for improving the response time of nematic LC, such as over-drive, materials development (e.g., low viscosity, high birefringence, etc.), virtual walls, dual frequency, pi-cell or OCB, polymer stabilization, three-electrode design, etc. Some of these techniques have already been employed by industry, and some are still being actively researched and developed for next-generation displays and advanced photonics applications. Apart from nematic LC, other possible LC effects such as blue phase, flexoelectrics, Sm*C surface-stabilized ferroelectrics (SSFLC), Sm*C deformed-helix ferroelectrics (DHFLC), Sm*A, etc., may also be employed. These non-nematic LC effects can potentially achieve a much faster intrinsic response time compared to that of nematic LC. Thus, very active research has been carried out in recent years to develop these non-nematic LC effects for displays and advanced photonics applications. With the advancement of technologies such as photo-alignment, some of these non-nematic LC technologies have been demonstrated in recent years to be capable of producing high-quality and high-performance LC devices with a fast response time, high light efficiency, high pixel density, etc.  

In this Special Issue, we intend to focus on collecting papers that are related to some of the latest developments and advancements in this highly important topic of the fast response time of liquid crystals, for both nematic and non-nematic liquid crystals and for both display and non-display applications. We hope that this Special Issue can help bring together some of the latest research that can help further develop next-generation liquid crystal devices that will continue to require higher and higher operation speeds.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
