Research On The Photoelectric Characteristic Of Reflective Chlcd

The multi-domain bistable reflective cholesteric liquid crystal displays (ChLCD) have been a kind of remarkable reflective display in recent years. This display is realized by the two contrastive states between reflective bright state (Plannar texture's Bragg) and dark state (Focal Conic's scattered). It is a reflective display with low power consume because of its two stable states at zero field..The Paper mainly focused on technology of reflective CHLCD including the fabrication of electrode, the printing of PI, rubbing and the perfusion of liquid crystal. On the base, the effect of technology parameters on multi-domain structure and photoelectric characteristic had been researched. During the research on multi-domain structure, the transition of P phase to FC phase, FC phase to H phase and H phase to P phase or FC phase had been mainly researched. Using the equipment of our lib, optimizing the parameters of technology, the results of technology experiments and sample screen have been achieved. Applying the reflected model of CHLCD photoelectric characteristic, connecting the dates of experiments, the basic reflected rule of CHLCD had been achieved. The relationship between liquid crystal materials, solidify, rubbing and photoelectric characteristic had been given. Weakening the rubbing the pile impression and rotation frequency, increasing the roller transport velocity are helpful to form the multi-domain and low the phase transition voltage.
