    • A liquid crystal panel (1) includes plural signal lines and scanning lines disposed in matrix, and liquid-crystal-driving LSIs (5, 6) having input and output portions directly connected by thermocompression bonding with an anisotropically conductive adhesive (9). The LSIs are mounted on a conductor on a rim of the panel. Film jumper boards (10, 14), the respective numbers of which correspond to the number of the driving LSIs (5, 6), connects between a terminal conductor (21) at the rim of the liquid crystal panel (1) and circuit boards (12, 16). As a result, a liquid crystal display which can be designed freely, can be modified easily, can employs common components, and can have a defective driving LSI specified and repaired readily and accurately is provided. A method of inspecting the display is also provided.

    • To eliminate display unevenness caused by lateral luminance error or longitudinal luminance error or crosstalk in image display on liquid crystal panel by using a low-cost drive circuit, relating to a liquid crystal panel 14 having 2N scanning lines (12) arranged in the horizontal direction, and M signal lines (10, 11) disposed in the vertical direction, in which the scanning lines (12) are driven simultaneously at both ends by using scanning line left drive circuit (17A) and scanning line right drive circuit (17B). Drive pulses are sequentially applied to the scanning lines (12) at addresses X1 to X2N to turn on the individual scanning lines (12). Necessary voltage pulses are simultaneously applied to the signal lines (10, 11) at addresses Y1 to YM to control each pixel. As compared with the conventional method of one-end driving, the luminance error is reduced to ¼, and it is effective for enhancing the picture quality, especially in large-sized liquid crystal panels.
    • 为了通过使用低成本驱动电路来消除液晶面板上的横向亮度误差或纵向亮度误差或串扰造成的显示不均匀,涉及具有沿水平方向布置的2N条扫描线(12)的液晶面板14 以及通过使用扫描线左驱动电路(17A)和扫描线右驱动电路(17B)在两端同时驱动扫描线(12)的垂直方向上配置的M条信号线(10,11)。 在地址X1〜X2N的扫描线(12)依次施加驱动脉冲,使各个扫描线(12)导通。 对地址Y1〜YM的信号线(10,11)同时施加必需的电压脉冲,以控制每个像素。 与常规的一端驱动方法相比,亮度误差降低到1/4,对于提高图像质量是有效的,特别是在大尺寸液晶面板中。

    • A wire cut electric discharge machine for electric discharge machining a work (W) held on a work table (24). A wire electrode (14) supplied by a wire supplying device (12) is passed between upper and lower heads (22, 26) under tension through an electric discharge machining region where the work (W) is subjected to electric discharge machining. When a breakage of the wire electrode is detected during the electric discharge machining operation by a suitable detector, the broken wire electrode is drawn back and held in the neighborhood of the upper head (22) by a wire electrode feeding mechanism, the broken end of the wire electrode is detected outside the electric discharge machining region by a broken end detecting device (66), the work table is shifted by a XY driving mechanism from the electric discharge machining region to a predetermined wire repairing position, the broken end is cut and removed to repair the wire electrode with a cutter (60) and a cutting block (64) at a wire electrode repairing position separated from the electric discharge machining region, the work table is returned to the electric discharge machining region by the XY driving mechanism, the repaired wire electrode (14) is extended again between the upper and lower heads (22, 24) by means of a jet nozzle (74), and then the electric discharge machining operation is restarted.
