【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(450nm,550nm,650nm)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]:Due to the existence of Dead Dead Zone1, the traditional planar torsional In-Plane switching (IPS) mode polymer stabilized blue-phase liquid crystal display devices have low transmittance. By introducing floating electrode to increase the transverse electric field intensity above the dead zone, this problem can be solved and the overall transmittance of the blue liquid crystal display device can be improved. The electro-optic characteristics of blue liquid crystal display devices with floating electrodes are simulated by Techwiz3D program. The effects of electrode size, working wavelength and electrode dislocation on electro-optic characteristics were calculated quantitatively. The simulation results show that the transmittance of IPS mode blue liquid crystal display devices with floating electrodes has been increased by about 15 percent, and the overall transmittance of three kinds of visible light wavelength devices, which are usually used in display applications, is about 90nmg. The new device structure can significantly improve the transmittance of blue liquid crystal display devices and make them gain more advantages in the development and competition of the new generation of display technology.
