快速响应的共面转换型液晶显示器
Fast-response in-plane switching liquid crystal display
摘要
Abstract
Excellent viewing angle and outstanding ability of color reproduction in-plane switching liq-uid crystal displays (IPS-LCDs)are widely applied in TFT-LCD.However,its development in high-end LCD is limited by its slow response.In this paper,the electro-optic characteristics and response time of FFS and FIS modes in the IPS type are simulated with different rubbing angle by using the positive liquid crystal material.Furthermore,we report a simple method to reduce the response time in the fringe and in-plane switching (FIS)cell by optimizing tilt angle,electrodes size,and elastic constants.Through the simulations,we can obtain that the rubbing angle has a great influence on operating voltage in FFS cell,and small rubbing angle can achieve high transmittance and low operat-ing voltage.However,the rubbing angle has a great impact on the response time in FIS cell.When the angle is greater than 10°,the response speed is increased by more than 82.7% compared with 2°.In addition,the elastic constants have an effect on the response time under different rubbing angles in the FIS mode.When the rubbing angle is 2°,the response speed is related to K 11 ,K 22 and K 33 .When the rubbing angle is 12°,the response speed is only related to K 22 ,which results in an increase in switc-hing speed of 84.2% compared to 2°.关键词
