“…Therefore, when an ICR layer is placed between the FFS array and LC layer, it causes a rapid increase in the operating voltage (V op ), since an average twisted angle of LC director from its initial orientation in the transmissive part should be 45u, which will exceed the driver integrated circuit (IC) range for mobile application. To solve this issue, slit angles, defined as the angle between the horizontal field direction and the initial LC director in the transmissive and reflective parts, were adjusted, respectively, to change the V op , although the results were not satisfactory (4,5).…”

When a dielectric layer, in-cell retarder (ICR) is formed between the electrode and LC layer to obtain a single-gap transflective fringe-field switching (FFS) display, the driving voltage is highly increased due to the thickness of the dielectric material. In particular, the driving voltage of the transmissive part becomes very high, and goes beyond the driver integrated circuit (IC) range for mobile application because the homogenously aligned liquid crystal director should rotate twice as far as that in the reflective part. The correlation between the driving voltage and electrode structures was investigated. It was found that the problem could be solved by optimisation of the common electrode structure such that the electrode structure changed from a plane to slit shape (in-plane field is mainly used instead of fringe field), realising a high performance FFS transflective display.

This paper investgates the transflective liquid crystal displays (LCDs) associated with fringe-field switching (FFS) mode to achieve high image quality. In the past, several cell structures were used to fabricate transflective FFS LCDs. Their structures and characteristics are carefully examined to find their merits and demerits. In addition, we attempt to optimize cell parameters to achieve a single driving circuit.

A conventional single gap transflective fringe‐field switching display has a difficulty in fabricating a reflector with embossing. To solve this problem, we propose a new structure which has the reflector on the color filter side, without deteriorating reflectance and transmittance. and this single gap transflective LCDs has a problem such that the voltage‐dependent transmittance and reflectance curves do not match each other and thus a dual driving circuit is required. New FFS electrode structure which optimized an angle of the electrode in the transmissive and reflective area solves this problem so that the transflective display with a single gamma curve and for reflective and transmissive region is possible.

P-111: Voltage and Rubbing Angle Dependent Behavior of the Single Cell Gap Transflective Fringe Field Switching (FFS) Mode

Abstract: Rubbing angle-dependent electro-optic characteristics in the single cell gap transflective FFS mode have been studied. The adjustment of the rubbing angle reduces the difference in voltagedependent reflectance and transmittance curves.
