Detection sensor and display device

A detection sensor, comprising:

• a first electrode member on a base layer and including a plurality of first sensing electrodes each including a first opening and electrically connected to each other along a first direction;
• a second electrode member on the base layer and including a plurality of second sensing electrodes each including a second opening and electrically connected to each other along a second direction crossing the first direction;
• a first conductive member including a plurality of first conductive patterns electrically connected to each other along the first direction;
• a second conductive member including a plurality of second conductive patterns electrically connected to each other along the first direction and spaced apart from the first conductive member;
• and
• a sensor controller configured to detect a change of a mutual capacitance between the first electrode member and the second electrode member in a first mode and configured to detect a change of a mutual capacitance between the second conductive member and the second electrode member or a change of a mutual capacitance between the second conductive member and the first electrode member in a second mode different from the first mode,
• wherein the first conductive pattern is in the first opening, and the second conductive pattern is in the second opening.

A display device, comprising:

• a base substrate;
• a self-light emitting element on the base substrate;
• a thin film encapsulation layer on the self-light emitting element;
• a first sensing electrode on the thin film encapsulation layer and including an opening;
• a second sensing electrode on the thin film encapsulation layer and spaced apart from the first sensing electrode;
• a conductive pattern in the opening and spaced apart from the first sensing electrode;
• and
• a sensor controller configured to detect a change of a mutual capacitance between the first sensing electrode and the second sensing electrode in a first mode and configured to detect a change of a mutual capacitance between the conductive pattern and the first sensing electrode in a second mode different from the first mode.
