高透过率共面转换液晶显示器 总被引:1,自引:0,他引:1
我们开发了一种在同一个基板上使用特殊电极设计的高透过率共面转换(HT-IPS)液晶显示器。这种特殊的电极构造在电极组之间产生实际的水平电场,在电极组区域内的边缘电场具有较高水平场成份。上半部分类似于IPS模式,而下半部分类似于边缘场转换(FFS)模式。HT-IPS模式显示出了很高的透过率[大于扭曲向列相(TN)模式的90%],同时,无论使用正性或负性各向异性的液晶材料,液晶盒都具有宽视角。此外,我们对比了相同条件下HT-IPS与IPS、FFS盒的光电特性。 相似文献

利用染料掺杂双频率液晶胶体材料制备了一种对比度高、响应速度快且无需偏光片的反射式显示器。器件的高对比度是由于聚合物胶体材料对光的散射和黑色染料分子对光的吸收。对双频率液晶材料进行频率调制使得器件产生较快的响应速度。 相似文献

3-D Liquid Crystal Displays and Their Applications 总被引:2,自引:0,他引:2

Three-dimensional (3-D) data is regularly used to create 3-D images that are rendered onto a plane and shown on a two-dimensional (2-D) display. Stereoscopic displays are becoming more widespread and are currently available at consumer level prices. With these displays it is possible to see images with a high-quality perception of depth and with a greater sense of realism. It is an exciting time in the 3-D displays market as the current generation of 3-D display technologies continues to develop. A number of technologies for 3-D displays have existed for some time, many of which are based on liquid crystal displays (LCDs). LCDs combined with the parallax barrier method have a number of advantages in terms of cost, ease of manufacture, size, weight,and most importantly the ability to switch from 2-D to 3-D mode. Several consumer products are available based on this type of display. Applications such as entertainment, scientific visualization, advertising, and education benefit greatly from the improved realism offered by stereoscopic displays. There are many challenges to creating suitable images for 3-D displays; some have been solved and others are receiving attention. In order to build the 3-D display market, industry will need to tackle all of them in order to support the content creators and provide the features and ease of use that end users require. The aim of this paper is to describe and compare the core 3-D display technologies, bring together a number of important considerations for content creation and discuss some of the applications that have a strong benefit from using 3-D images on a 3-D display. 相似文献

A series of low transition temperature and fast response chiral smectic C (SmC*) liquid crystals is designed and synthesized. The phase transition behaviors and electrooptical properties of the synthesized compounds are investigated and compared with reported values. The ferroelectric phase of the liquid crystals is characterized by means of differential scanning calorimetry, polarizing optical microscopy, wide‐angle X‐ray scattering (WAXS), and electrooptical measurements. The wide SmC* phase is achieved via the induction of achiral trisiloxane and a chiral methyl‐lateral substituent onto the terminuses of the molecules. The optimized packing arrangement model is studied based on the exceptionally high apparent tilt angles (≈41°) and smectic layer spacing observed using WAXS. A fast response time of 0.3 ms in an electric field of 10 V µm?1 provides an opportunity to use the synthesized materials for field‐sequential color liquid crystal displays (FSCLCDs). An FSCLCD sample cell is fabricated using the synthesized ferroelectric liquid crystals via a red (R), green (G), and blue (B) backlight. A color‐frame frequency of more than 500 Hz (i.e., a frame frequency more than 166 Hz) is achieved. As a single material liquid crystal display cell, the synthesized ferroelectric liquid crystals show great performances at room temperature. 相似文献
