Abstract: A planar heating structure is disclosed. The planar heating structure includes a glass substrate layer, a nanometallic transparent conductive layer, and a first passivation layer. The nanometallic transparent conductive layer is disposed on the glass substrate layer and receives a voltage to generate heat energy. The first passivation layer is disposed on the nanometallic transparent conductive layer and completely covers the nanometallic transparent conductive layer.

Abstract: A touch control device includes a cover lens, a groove, a fingerprint, and a touch sensing structure. The cover lens has a first surface and a second surface opposite to the first surface, in which the first surface is a touch surface. The groove is disposed on the second surface and has a top surface and a side surface adjacent to the top surface, in which an angle between the top surface and the side surface is greater than 90°. The fingerprint recognition structure is at least partially disposed on the top surface of the groove. The touch sensing structure is disposed on the second surface.

Abstract: A touch display device includes a transparent substrate, a first ink layer, a shading layer, and a decorative layer. The transparent substrate has a visible region and an non-visible region. The non-visible region is located at the peripheral of the visible region. The first ink layer is disposed on the non-visible region of the transparent substrate. The shading layer is disposed on the first ink layer. The decorative layer is disposed on a portion of the first ink layer and located between the first ink layer and the shading layer. The optical density of the first ink layer is between 0.3 and 0.67.

Abstract: A touch device comprises a touch sensing structure, a cover lens, a first mask layer, a second mask layer and a fingerprint identification structure. The cover lens has a first surface and a second surface opposite to the first surface. The cover lens has a groove; the groove is disposed on the second surface and has a top surface and side surfaces adjacent to the top surface. The first mask layer covers the top surface of the groove. The second mask surface covers the side surface of the groove. The color of the first mask layer and the second mask layer are different. At least a portion of the fingerprint identification structure is disposed on the top surface in the groove. The touch sensing structure is disposed on the second surface.
