  • Bistable bend-splay Liquid Crystal Display
    Applied Physics Letters, 2004
    Co-Authors: X J Yu, Hoi Sing Kwok
    Abstract:

    A bistable Liquid Crystal Display based on the bend and splay configurations has been demonstrated.\rThis Display can be switched between the bend and splay deformation in a three-electrode\rconfiguration and has infinite bistable lifetime. It also has wide viewing angles, excellent contrast\rratios, and very fast selection. Selection electric pulse duration of 50 ms can be used to switch this\rDisplay, implying the possibility of a high information content applications.

  • truly bistable twisted nematic Liquid Crystal Display using photoalignment technology
    Applied Physics Letters, 2003
    Co-Authors: Fion Sze Yan Yeung, Hoi Sing Kwok
    Abstract:

    Truly bistable twisted nematic Liquid Crystal Display has been fabricated using photoalignment. This Display can be switched between the −22.5° and 157.5° twist states by breaking the anchoring condition on one of the substrates. The application of a photoalignable polymer SDA-1 was able to achieve the weak anchoring energy necessary for switching. Both theoretical and experimental results show that this mode has excellent contrast ratio and wide viewing angles.

  • reflective bistable twisted nematic Liquid Crystal Display
    Japanese Journal of Applied Physics, 1998
    Co-Authors: Zhiliang Xie, Hoi Sing Kwok
    Abstract:

    A reflective bistable twisted nematic (BTN) Liquid Crystal Display has been developed. It combines the advantages of a truly reflective Display without the rear polarizer, and the bistable nature of the zero voltage state. It was found experimentally that switching between the two bistable twist states could be achieved by adjusting the magnitude of the selection voltage pulse, just like the case in transmittive BTNs. In demonstrating the reflective BTN, we also show for the first time bistability between the -36° and 324° twist states.

  • Optically controllable bistable reflective Liquid Crystal Display.
    Optics letters, 2012
    Co-Authors: Chun-ta Wang, Hung-chang Jau, Tsung-hsien Lin
    Abstract:

    This Letter demonstrates a photo-addressable, bistable reflective Liquid Crystal Display that is based on a dye-doped Liquid Crystal (DDLC). Bistable bright and dark states can be attained using the 45 deg twisted nematic (TN) and photo-induced isotropic states (PHI) of the DDLC, respectively. Both the 45 deg TN and PHI states can exist stably for tens of hours, and each can be rapidly switched to the other by the isomerization effect using UV and green light. A bistable reflective Liquid Crystal Display is simply fabricated, easily operated, and rapidly switched. It therefore has the potential to be used in portable information systems.

  • photoaddressable bistable reflective Liquid Crystal Display
    Applied Physics Letters, 2006
    Co-Authors: Tsung-hsien Lin, Hung-chang Jau, Sanyi Hung, Hueiru Fuh, Andy Yingguey Fuh
    Abstract:

    This work presents a bistable reflective Liquid Crystal Display. The mechanism is based on the laser-induced adsorption of azo dyes on the polymer-coated glass substrate. This reflective Liquid Crystal Display is very simple to fabricate and can be optically written, erased, and rewritten with a high contrast. A simulation is performed to fit the measured electro-optical characteristics of this device.

    Co-Authors: Liwei Liu, Jianpeng Cui, Qiong-hua Wang
    Abstract:

    The invention provides a viewing angle controllable blue phase Liquid Crystal Display comprising an upper substrate, a Liquid Crystal layer and a lower substrate. The upper substrate and the lower substrate are parallel to each other and respectively consist of main pixels and sub-pixels; the main pixels and sub-pixels are made of the same blue phase Liquid Crystal material; transparent strip pixel electrodes and transparent strip public electrodes are arranged at intervals on the lower substrate; the transparent strip electrodes of the upper substrate are arranged in the range of the sub-pixels of the upper substrate; the conversion between a narrow viewing angle mode and a wide viewing angle mode is achieved by selecting whether to apply an offset voltage to the electrodes of the upper substrate. The viewing angle controllable blue phase Liquid Crystal Display has a good viewing angle control effect, high transmission rate and a simple manufacturing process and is simple and convenient to operate.
