    • More particularly, the present invention relates to an input system using unit patterns representing absolute coordinate information and an electronic pen that may recognize the patterns. The input system using the electronic pen according to the present invention includes: a coordinate pattern sheet on which a plurality of unit patterns representing absolute coordinate information are arranged; a pen tip moving on the coordinate pattern sheet; an electronic pen including a camera having a range of vision in which the pen tip and at least one of the unit patterns may be recognized together; and a controller obtaining absolute coordinate information on the unit pattern recognized by the camera, calculating the relative coordinates of the pen tip based on the unit pattern through the location of the pen tip and the location of the unit pattern recognized by the camera, adding up the relative coordinates of the pen tip and the absolute coordinates of the unit pattern, and calculating the absolute coordinates of the pen tip. The input system using the electronic pen according to the present invention may very easily make all surfaces, in addition to a display unit such as a computer monitor or a mobile terminal display, function as an input unit similar to a touch panel.
    • 更具体地,本发明涉及使用表示绝对坐标信息的单位图案的输入系统和可识别图案的电子笔。 使用根据本发明的电子笔的输入系统包括:坐标图案片,其上布置表示绝对坐标信息的多个单位图案; 笔尖移动在坐标图纸上; 一种电子笔,其包括具有视点范围的相机,其中笔尖和至少一个单元图案可以一起识别; 以及控制器获取关于由照相机识别的单位图案的绝对坐标信息,通过笔尖的位置和由照相机识别的单位图案的位置,基于单位图案计算笔尖的相对坐标,相加 笔尖的相对坐标和单位图形的绝对坐标,并计算笔尖的绝对坐标。 根据本发明的使用电子笔的输入系统除了诸如计算机监视器或移动终端显示器之类的显示单元之外,也可以非常容易地将所有表面用作类似于触摸面板的输入单元。

    • A liquid crystal display panel for improving a response speed of a liquid crystal and a left DC using a carbon nanotube, and a fabricating method thereof are discussed. In the liquid crystal display panel according to an embodiment, a color filter substrate has first thin film patterns. A thin film transistor substrate is formed in opposition to the color filter substrate and has second thin film patterns which form a horizontal electric field. And a liquid crystal composition is injected between a cell gap formed by the two substrates and is rotated in a horizontal direction in accordance with a horizontal electric field, wherein the liquid crystal composition includes liquid crystals and carbon nanotubes which are dispersed between the liquid crystals in a predetermined quantity.
