Disclosed herein are a touch panel and a fabricating method thereof. In the touch panel according to an embodiment of the present invention, a noise shielding layer may be separately formed between a transparent substrate and an electrode pattern, thereby shielding noise that occur from a display coupled to the touch panel. In addition, through a bridge electrode pattern formed by patterning the noise shielding layer and a bridge insulating pattern patterned on an insulating layer formed on the noise shielding layer, a first electrode pattern and a second electrode pattern may be formed on the same plane of the transparent substrate so as to intersect with each other, thereby ensuring reliability of electrical connection between each electrode pattern.

Touch panel and fabricating method thereof

Disclosed herein are a touch screen and a method for driving the same. The touch screen includes: a switching unit including a plurality of switches connected to traces of driving lines and sensing lines of the touch screen, respectively; a sensing unit sensing capacitance and electromagnetic resonance (EMR) according to a switching operation of the switching unit; and a main controlling unit controlling the switching operation of the switching unit according to an operation mode of the touch screen. Therefore, it is possible to improve sensitivity of sensing without increasing a bezel region of the touch screen. In addition, the EMR and the capacitance may be sensed using the same trace structure, and an antenna pattern may be formed and operated as an antenna.

Touch screen and method for driving the same

Disclosed herein is a digitizer including: an input unit having a magnetic field shielding part embedded therein; a driving coil supplied with current to induce a magnetic line of force; a sensing coil to which voltage is induced by the magnetic line of force; and a control unit supplying current to the driving coil and measuring voltage induced to the sensing coil, wherein the control unit senses variation of voltage induced to the sensing coil to calculate coordinates of the input unit when the voltage induced to the sensing coil is changed by the magnetic field shielding part.

Digitizer

Disclosed herein is a digitizer including: a driving coil supplied with current to induce a magnetic line of force; a sensing coil disposed so as to intersect the driving coil to flow induced current in one direction by the magnetic line of force; and a control unit sensing variation of voltage induced to the sensing coil to calculate coordinates of the input unit when the voltage is changed due to an approach of an input unit.

Disclosed herein is a display device having a capacitive touch screen, including: a display unit; and a capacitive touch screen that is coupled to the display unit by an adhesive layer and includes a base substrate, a plurality of first electrode patterns that are formed on an active region of the base substrate, ground patterns that are formed on the active region of the base substrate and are separated from the first electrode pattern, a transparent insulating layer that covers the first electrode patterns and the ground patterns and is formed on the base substrate, and a plurality of second electrode patterns that are formed on an active region of the transparent insulating layer.

Display device having capacitive touch screen

Disclosed is a method for correcting inner pin distortion generated in the CRT product and deflection yoke thereof. According to the disclosed method and deflection yoke thereof, the additional circuit for suppressing inner pin distortion phenomenon on the screen is not required as the related art, reduction in manufacturing costs is possibly achieved. Also, as the circuit for suppressing pincushion is not used, power dissipation could be reduced, and instability in dispersion and characteristics of a pin in the middle portion due to increase of dispersion generation by a wiring of a coil could be resolved.
