A common-voltage compensation driving apparatus and method and a crosstalk-compensation driving apparatus of an AMLCD detect current flowing through a common electrode for an optional period to compensate for a common electrode voltage by using the current value as a reference and eliminate crosstalk resulting from the variation of a video data value. The common-voltage compensation driving apparatus includes a current detector for detecting the current flowing through a common electrode for an optional period, a proportional voltage generator for integrating the current detected by the current detector to generate a proportional voltage corresponding to the integrated current, a common voltage generator for compensating the proportional voltage of the proportional voltage generator to a common electrode voltage during a compensating period shorter than one horizontal scanning period, and a controller for controlling driving times of the current detector, proportional voltage generator and common voltage generator. The method therefor is performed by a current detecting step, a proportional voltage generating step, and a common voltage generating step. The crosstalk compensation driving apparatus has the current detector, the proportional voltage generator, a data signal voltage compensator for compensating the proportional voltage of the proportional voltage generator to a data signal voltage output during a compensating period shorter than one horizontal scanning period, and the controller.

A touch panel-mounted liquid crystal panel minimizes picture distortion upon driving of the touch panel. In the liquid crystal panel, a lower glass substrate has switching devices provided in the vicinity of intersections between data lines and gate lines. An upper glass substrate has a black matrix joined to it. Patterned clusters of spacers are positioned at an area corresponding to the black matrix in such a manner to enlarge its contact area with the upper glass substrate, thereby keeping a uniform distance between the upper and lower glass substrates. The enlarged contact area allows the patterned clusters of spacers to sufficiently absorb a pressure load of a finger or a stylus pen. Accordingly, uniform distance between the upper and lower glass substrates is maintained even upon driving the touch panel. As a result, light deterioration and local image distortion is prevented or minimized.

摘要:
A method and apparatus of driving a liquid crystal panel to prevent an image distortion and a non-uniform phenomenon in the light transmissivity caused by propagation delay in a scanning wiring of the liquid crystal panel. Data signal voltages are supplied to a signal wiring with a predetermined time interval in accordance with a delay characteristic of a scanning signal in the scanning wiring. Accordingly, even when the scanning signal is delayed in the scanning wiring, the data signal voltages are accurately applied to all liquid crystal cells and hence a picture displayed on the liquid crystal panel is not distorted.

An apparatus for locating a point physically touched and producing an electrical signal corresponding to the location includes an insulating substrate; a resistor touch pattern supported on the insulating substrate; and a protective insulating plate arranged over the resistive touch pattern. The resistive touch pattern has a plurality of strip resistors parallel to a center line; a plurality of linear resistors connected to the strip resistors, the resistance of the linear resistors decreasing with distance from the center line; first and third terminals positioned on an intermediate point of alternate edges of the touch pattern; and second and fourth terminals, positioned on an intermediate point of other alternate edges of the touch pattern. The resistive value of the linear resistors selected for a corresponding strip resistor so as to produce equal potential at a corresponding selected point on all said strip resistors.

A liquid crystal display (LCD) device having a digitizer. A liquid crystal panel is supported by a lower frame having a side wall portion. A digitizer is located on the liquid crystal panel. An upper frame having a front surface with an opening region and a side wall portion is located over the digitizer such that the tipper frame pressurizes a peripheral portion of the digitizer. The opening region is formed at a location corresponding to the display region of the liquid crystal panel. The upper and lower frames mate to hold the liquid crystal panel and the digitizer in place. The upper frame is beneficially metallic to provide electrical shielding of conductors on the digitizer. Common electrical circuits are shared by the digitizer and the liquid crystal panel.
