    • Disclosed is a liquid crystal display device comprising a display part. The liquid crystal display device allows a common electrode voltage swinging depending on a gate off voltage of the display part to be fed-back through a feed-back circuit and to be held at a constant level, thus stabilizing the common electrode voltage and the gate off voltage coupled to a capacitance component, thereby preventing a picture displayed on the liquid crystal display panel from being divided into blocks. The common electrode voltage is detected at a position capable of being connected to the common electrode. The detected common electrode voltage is input into a comparator for outputting the common electrode voltage. The output of the comparator is controlled to thereby control the swing of the common electrode voltage.

    • The present invention relates to a method and an apparatus for testing the surface properties, i.e., abrasion property, friction coefficient, lubrication property, etc., of cylindrical object, e.g., VTR head drums, photocopier or laser printer drums, sewing machine spindles, fishing rod reels, etc. The apparatus of the present invention provides: a mounting means upon which a specimen of cylindrical object and a relative specimen of a flexible material is mounted and which can measure tension; a motor control unit which is connected to said mounting means so as to enable control; an amplifier electrically connected to a tension meter of said mounting means; and a computer, electrically connected to said amplifier and said motor control unit, which has been programmed to record at timed intervals the motor rotation speed and the estimated tension values, and organizes and controls all of the above said parts. Further, said mounting means including a motor where cylindrical specimen is positioned and whose revolution may be accurately controlled; a tension meter wherein each end of said relative specimen is mounted where said relative specimen is wrapped around said specimen so that at least of part of the flexible material is in contact with said specimen; and a tension meter support upon which said tension meter is mounted. According to the present invention, the abrasion and lubrication properties of cylindrical object with respect to the relative material, such as magnetic recording tape, paper, wire, etc., which could not be gauged with previous methods, may be evaluated.
