    Abstract: In a method for fabricating a lightweight and thin liquid crystal display (LCD), a first mother substrate, a subsidiary substrate and a thin second mother substrate are provided. An edge cut is formed by cutting edges of the first and second mother substrates and the subsidiary substrate to be inclined at a predetermined angle. An array process is performed on the first mother substrate. The subsidiary substrate is attached to the second mother substrate. A color filter process is performed on the second mother substrate having the subsidiary substrate attached thereto. The first and second mother substrates are attached together. The subsidiary substrate is separated from the first and second substrates by spraying air between the second mother substrate and the subsidiary substrate, in which the edge cut is formed.

    Abstract: A display device having a built-in touchscreen and a driving chip, a circuit film, and a chip-on-film (COF) type driving circuit included in the display device. The COF type driving circuit performs data driving and touch driving in a combined manner. A source driving circuit outputs image data voltages through data channels. At least one touch driving circuit outputs touch driving signals through touch channels. The source driving circuit and the at least one touch driving circuit are mounted on an integrated circuit film. Data channel lines electrically connected to the data channels and touch channel lines electrically connected to the touch channels are disposed on the integrated circuit film. The noise avoidance line disposed on the integrated circuit film is located outward of an at least one outermost touch channel line.

    Abstract: A touch display device includes: a touch panel including N touch electrodes; a sensor sensing unit block including M sensor sensing units and to sense two or more touch electrodes among the N touch electrodes; a front multiplexer to select two or more touch electrodes from among the N touch electrodes and connect the selected touch electrodes to the sensor sensing unit block. The front multiplexer is configured to select M touch electrodes, which are disposed in a sensing active region corresponding to a first sensing period, from among the N touch electrodes, and to match and connect the M touch electrodes to the M sensor sensing units, wherein M is greater than or equal to 2, and N is greater than M. The M sensor sensing units are configured to simultaneously sense the M touch electrodes disposed in the sensing active region during the first sensing period.
