Abstract
A display apparatus includes a display panel configured to display an image, a shift register configured to output a gate signal which is to be applied to the display panel, based on a periodicity signal output from a level shifter, a pseudo generator configured to sense the periodicity signal to convert it into a current and invert a phase to output as a pseudo signal of an inverted current type, and a pseudo pattern part disposed on the display panel, the pseudo pattern part including a pattern where the pseudo signal is applied.

A display apparatus comprising:
- a display panel configured to display an image;
- a shift register configured to output a gate signal that is applied to the display panel based on a periodicity signal that is output from a level shifter;
- a pseudo generator configured to sense the periodicity signal to convert the periodicity signal into a current and invert a phase to output as a pseudo signal of an inverted current type;
- and
- a pseudo pattern part on the display panel, the pseudo pattern part including a pattern where the pseudo signal is applied,
- wherein the pseudo generator comprises a current sensing and phase inverting circuit including a first transistor configured to sense the periodicity signal to convert the periodicity signal into a current and a second transistor configured to operate identical to the first transistor and invert a phase of a sensed current to output as the pseudo signal of the inverted current type.
A pseudo signal generator circuit comprising:
- a pseudo generator configured to sense a periodicity signal to convert the periodicity signal into a current and invert a phase to output as a pseudo signal of an inverted current type;
- and
- a pseudo pattern part including a pattern for offsetting an electric field generated from the periodicity signal, based on the pseudo signal,
- wherein the pseudo generator comprises a first transistor configured to sense the periodicity signal to convert the periodicity signal into a current and a second transistor configured to operate identical to the first transistor and invert a phase of a sensed current to output as the pseudo signal of the inverted current type.
