Abstract:
1. A touch panel, comprising: a bottom panel having: an EMI shielding layer formed on a bottom surface of the bottom panel; multiple lower sensing areas formed on a top surface of the bottom panel, parallelly aligned in a first direction, each of the lower sensing areas having multiple lower sensing units serially connected; multiple first lower ports, each of the first lower ports formed on an edge of one of the outermost lower sensing units in the first direction; multiple second lower ports collectively formed on a bordering portion of a side of the top surface of the bottom panel, wherein a count of the second lower ports corresponds to that of the first lower ports; and multiple lower wires formed on the top surface of the bottom panel and respectively connected between the first lower ports and the second lower ports; an anisotropic conductive film formed on the top surface of the bottom panel and covered on the second lower ports; an insulating layer formed on the top surface of the bottom panel; a top panel formed on the anisotropic conductive film and the insulating layer, being larger than the lower panel and having: a protruded side protruding beyond the side of the bottom panel having the second lower ports thereon; multiple upper sensing areas formed on a bottom surface of the top panel, parallelly aligned in a second direction that is perpendicular to the first direction, and each of the upper sensing areas having multiple upper sensing units serially connected; multiple first upper ports, each of the first upper ports formed on an edge of one of the outermost upper sensing units in the second direction; multiple second upper ports formed on the bottom surface of the top panel and extending to a bottom surface of the protruded side, wherein a count of the second upper ports corresponds to that of the first upper ports; multiple transfer ports formed on the bottom surface of the top panel and extending to the bottom surface of the protruded side, wherein a count of the transfer ports corresponds to that of the second lower ports, and one end of each of the transfer ports corresponds to and is electrically connected with a corresponding second lower port; and multiple upper wires formed on the bottom surface of the top panel and respectively connected between the first upper ports and the second upper ports; and a flexible PCB mounted on the bottom surface of the protruded side, and electrically connected with the second upper ports and the transfer ports.
