Abstract
A touch sensing device and a display device for improving hovering performance including: a touch sensing display panel including sense electrodes arranged in a matrix; and a sensing signal controller connected to the touch sensing display panel. The sense electrode includes a metal mesh electrode and a conductive layer contacting the metal mesh electrode.
Claims12
A display device comprising:
- a substrate including a first area in which light is blocked and a second area in which light passes;
- a thin film transistor disposed on the substrate;
- a pixel electrode connected to the thin film transistor;
- a first layer disposed on the pixel electrode;
- and
- a sense electrode disposed on the first layer,
- wherein:
