Abstract

A touch display device includes a printed circuit board and a cover. The printed circuit board has a top surface, a bottom surface and soldering points. The printed circuit board includes a first printed circuit, a light element and a second printed circuit. A part of the first printed circuit is on the top surface or the bottom surface and connected with the corresponding soldering point. The light emitting element is on the top surface and electrically connected to the first printed circuit. On the top surface, the second printed circuit does not overlap with the first printed circuit. The cover covers the printed circuit board. The cover has light transmission areas which are aligned with the light elements. The second printed circuit is configured to provide a capacitance value coupled to a capacitive sensing element coupled between the second printed circuit and the cover.
