    • A high transmittance brightness enhanced optical element for backlight modules and liquid crystal display device is disclosed. The brightness enhanced polarizing optical element comprises a reflective polarizer film, a phase retardation film, and a polarization enhancement film. The reflective polarizer film provides a function of selectively reflecting right-handness circularly polarized light or left-handness circularly polarized light and will transmit the other one of them. The one was selectively reflected will be recombined with the light source or the backlight and re-direct toward the reflective polarizer. The portions of the reflective light will be recombined with the fresh light from the light source as above and the processes repeatedly. As a result, almost all of the light transmit the reflective polarizer and in the same circular polarization. The light is then transmitted the phase retardation film and converted to a polarized light with another optical axis.
    • 公开了用于背光模块和液晶显示装置的高透光率亮度增强型光学元件。 亮度增强偏振光学元件包括反射偏振膜,相位延迟膜和偏振增强膜。 反射偏振膜提供选择性地反射右手圆偏振光或左手圆偏振光的功能,并且将透射另一个。 选择性地反射的光将与光源或背光重新组合并重新指向反射型偏振器。 如上所述,反射光的部分将与来自光源的新鲜光重新组合,并重复处理。 结果,几乎所有的光透射反射偏振器并且以相同的圆偏振。 然后将光传输相位延迟膜,并用另一个光轴转换成偏振光。

    • A wire grid polarizer with double metal layers for the visible spectrum. Parallel dielectric layers having a period (p) of 10˜250 nm and a trench between adjacent dielectric layers overlie a transparent substrate. A first metal layer having a first thickness (d1) of 30˜150 nm is disposed in the trench. A second metal layer having a second thickness (d2) of 30˜150 nm and a width (w) overlies on the top surface of each dielectric layer. The first and second metal layers are separated by a vertical distance (l) of 10˜100 nm. The first thickness (d1) is the same as the second thickness (d2). A ratio of the width (w) to the period (p) is 25˜75%.
