    • Disclosed is a reflection type liquid crystal display (LCD) and a manufacturing method thereof. A first substrate on which a pixel array is formed is prepared. A second substrate is formed facing the first substrate. A liquid crystal layer is formed between the first and second substrates. A reflective electrode is formed on the first substrate. The reflective electrode includes a plurality of first regions and a plurality of second regions having a height difference relative to the first regions, in which a first total sum in length components of the second regions arranged along a direction perpendicular to a first direction is greater than a second total sum in length components of the second regions arranged along a direction perpendicular to a second direction such that the second regions have higher reflectivity in the first direction relative to the second direction. A reflective electrode of oriented micro lenses defined by the first grooves and the second grooves is provided to enhance a reflection efficiency. The contrast and image quality are improved remarkably. The micro lenses are suitable for electronic displays that need a high reflectivity towards a specific direction. Since the reflective electrodes may be formed by an improved exposure and development process, the manufacturing cost and time would be reduced.
    • 公开了一种反射型液晶显示器(LCD)及其制造方法。 准备形成有像素阵列的第一基板。 形成面向第一基板的第二基板。 在第一和第二基板之间形成液晶层。 在第一基板上形成反射电极。 反射电极包括多个第一区域和多个相对于第一区域具有高度差的第二区域,其中沿着垂直于第一方向的方向布置的第二区域的长度分量的第一总和大于 沿着与第二方向垂直的方向布置的第二区域的长度分量的第二总和,使得第二区域在相对于第二方向的第一方向上具有较高的反射率。 提供由第一凹槽和第二凹槽限定的定向微透镜的反射电极以增强反射效率。 对比度和图像质量得到显着改善。 微透镜适用于需要朝向特定方向的高反射率的电子显示器。 由于可以通过改进的曝光和显影处理形成反射电极,所以制造成本和时间将会降低。

    • A method of converting an image rate by using image scaling includes changing a resolution of an input original image sequence and generating a changed resolution image sequence; determining a first motion vector by estimating motion of a first image by using a plurality of images from the changed resolution image sequence; determining a second motion vector by modifying the first motion vector of the first image to correspond to a resolution of an original image of the original image sequence, where the original image corresponds to the first image; detecting characteristic information of the original image; determining a third motion vector corresponding to the resolution of the original image by compensating the second motion vector based on the detected characteristic information; and converting an image rate of the input original image sequence based on the detected characteristic information of the original image and the third motion vector.
    • 通过使用图像缩放来转换图像速率的方法包括改变输入原始图像序列的分辨率并生成改变的分辨率图像序列; 通过使用来自改变的分辨率图像序列的多个图像估计第一图像的运动来确定第一运动矢量; 通过修改第一图像的第一运动矢量来对应于原始图像的原始图像的分辨率来确定第二运动矢量,其中原始图像对应于第一图像; 检测原始图像的特征信息; 通过基于检测到的特征信息来补偿第二运动矢量来确定与原始图像的分辨率对应的第三运动矢量; 以及基于检测到的原始图像的特征信息和第三运动矢量来转换输入的原始图像序列的图像速率。
