20100128215LIQUID CRYSTAL DISPLAY AND FABRICATION METHOD THEREOF - A liquid crystal display (LCD) and a fabrication method thereof are provided. The LCD includes a first substrate and a second substrate opposite to the first substrate. At least two layers of cholesteric liquid crystal layers are disposed between the first and the second substrates, wherein chiral dopants with different optical activities are respectively added in the cholesteric liquid crystal layers, and the chiral dopants have the same chemical structure. The fabrication method includes providing a first substrate and a second substrate opposite to the first substrate. A plurality of chiral dopants with different optical activities and having the same chemical structure are mixed into the same liquid crystal host respectively to form at least two kinds of cholesteric liquid crystal materials. Then, the cholesteric liquid crystal materials are disposed between the first and the second substrates to form at least two layers of cholesteric liquid crystal layers.05-27-2010
20100295875DRIVING METHOD AND DISPLAY DEVICE UTILIZING THE SAME - A display device including a gate driver, a data driver and a plurality of sub-pixels is disclosed. The gate driver sequentially asserts a first scan signal and a second scan signal. The data driver provides a first data signal and a second data signal. When the first scan signal is asserted, the first scan signal and the first data signal respond with a first response signal. When the second scan signal is asserted, the second scan signal and the second data signal respond with a second response signal. The pulse of the first response signal is different from the pulse of the second response signal. A first sub-pixel among the sub-pixels displays a first color according to the first response signal. A second sub-pixel among the sub-pixels displays a second color according to the second response signal, and the first color is different from the second color.11-25-2010

20100081005Friction Stir Welding Tool and Weld Metal Structure with Plural Onion Rings - A friction stir welding tool and weld metal structure with plural onion rings, in which the tool is formed on the tool head with three surfaces, which are connected to one another through three spaced surfaces. An eccentrical axis of the tool head deviates from a central axis of the tool handle. One of the three surfaces is a deviation cutting surface which is a flat surface formed by cutting off a wall thickness from one side of an outer peripheral surface of the tool head toward the central axis of the tool handle. Each of the three spaced surfaces is alternately formed with plural notches and plural protrusions. The above welding tool is used to perform a stir friction welding operation to two metals to form the weld metal structure with the same number of onion rings as the protrusions and notches of each of the spaced surfaces.04-01-2010
