Sensing device, display device including the same, and electronic device

A display device comprising:

• a light-emitting element arranged on a base layer;
• an encapsulation layer arranged on the light-emitting element;
• and
• a sensor arranged on the encapsulation layer,
• wherein the sensor comprises:
• a first sensor electrode extending in a first direction;
• and
• a second sensor electrode extending in a second direction and intersecting the first sensor electrode,
• wherein the second sensor electrode comprises:
• a first sensor pattern and a second sensor pattern, each of the first sensor pattern and the second sensor pattern not overlapping with the first sensor electrode;
• and
• a bridge pattern partially overlapping with the first sensor electrode and connecting the first sensor pattern and the second sensor pattern, and
• wherein the bridge pattern extends in a spiral form from a first end connected to the first sensor pattern to a second end connected to the second sensor pattern.

An electronic device, comprising:

• a processor providing input image data;
• a display module displaying an image based on the input image data;
• and
• a power supply supplying power to the display module,
• wherein the display module comprises:
• a display panel including pixels;
• and
• a sensor arranged on the display panel and sensing a touch input to the display module,
• wherein the sensor comprises:
• a first sensor electrode extending in a first direction;
• and
• a second sensor electrode extending in a second direction and intersecting the first sensor electrode,
• wherein the second sensor electrode comprises:
• a first sensor pattern and a second sensor pattern, each of the first sensor pattern and the second sensor pattern not overlapping with the first sensor electrode;
• and
• a bridge pattern partially overlapping with the first sensor electrode and connecting the first sensor pattern and the second sensor pattern,
• wherein the bridge pattern extends in a spiral form from a first end connected to the first sensor pattern to a second end connected to the second sensor pattern, and
• wherein the processor detects the touch input based on a change in capacitance, and detects a pressure of the touch input based upon a change in resistance of the bridge pattern in response to the pressure applied to the bridge pattern.
