摘要

传统平面内扭转（In-Plane Switching

IPS）模式的聚合物稳定蓝相液晶显示器件由于死区（Dead Zone）的存在，导致了透光率较低的问题。通过引入浮置电极（Floating Electrodes），增强死区上方的横向电场强度，可以解决这一问题，提高蓝相液晶显示器件的总体透过率。引入浮置电极的蓝相液晶显示器件的电光特性由Techwiz3D程序仿真予以分析。我们定量计算了电极尺寸、工作波长和电极错位对电光特性的影响。仿真结果表明，引入浮置电极的IPS模式蓝相液晶显示器件的透过率提高了约15%，对显示应用中常见的3种可见光波长（450 nm

550 nm

650 nm）的总体透过率都达到了约90%。该新型器件结构能够显著提升蓝相液晶显示器件的透过率，使之在新一代显示技术发展和竞争过程中获得更大的优势地位。

Abstract

Polymer-stabilized blue-phase liquid crystal display (PSBP LCD) driven by conventional in-plane -switching (IPS) electrodes suffers from low transmittance due to the existence of dead zones. A floating electrode is introduced to enhance the lateral electric field on dead zone areas

so as to improve the peak transmittance of BP LCD device. The electro-optical properties of floating electrode enhanced protrusive IPS blue-phase LCD is analyzed by Techwiz3D simulation. The impact of electrode dimension

operation wavelength and misalignment of floating electrodes is investigated quantitatively. Our simulation results indicate that floating electrode increases the transmittance by 15% and the overall transmittance reaches ~90% for all three visible wavelengths (450 nm

550 nm

650 nm) employed for display applications. This makes blue-phase LCD a more competitive candidate for next generation display technology.
