Abstract
A touch panel and a method for fabricating the touch panel are presented. The touch panel includes a panel and a conductive border. A touch circuit is formed on a first side of the panel. A conductive border is formed on a circumference of the first side along the touch circuit. A method for fabricating the touch panel is further presented. The touch circuit of the touch panel is integrated onto the panel, so as to reduce the number of substrates that need to be bonded, thereby avoiding problems caused by substrate bonding and effectively decreasing the overall thickness of the touch panel.
Claims13
A touch panel, comprising:
- a panel, acting as an only substrate for a touch circuit in the touch panel, having a first side printed with the touch circuit and a second side opposite to the first side, the second side of the panel, being configured to face a user and being devoid of a touch circuit, thereby allowing the user to perform touch screen functionality from the second side;
- a conductive border formed on a circumference of the first side along the touch circuit;
- and
- a recess, formed at two opposite peripheral edges of a second side surface of the panel, the recess being configured to face the user who performs touch screen functionality, the recess being configured to transmit signals generated by the touch circuit, wherein the touch circuit comprises a sensing unit, a driving unit, and an interconnection circuit therebetween.
A method for forming a touch panel, comprising:
- patterning indium tin oxide (ITO) pre-formed on a first side of a panel through laser imprinting so as to form a touch circuit on the first side of the panel, with a second side of the panel that is opposite the first side and devoid of a touch circuit, wherein the panel acts as an only substrate for the touch circuit in the touch panel;
- allowing the second side of the panel to be viewable to a user, thereby allowing the user to perform touch screen functionality from the second side;
- printing a first conductive material along the touch circuit onto a circumference of the first side of the panel, so as to form a conductive border;
- and
- forming a recess at two opposite peripheral edges of a second side surface of the panel, thereby allowing the recess to face the user who performs touch screen functionality, the recess being configured to transmit signals generated by the touch circuit, wherein
- the forming of the touch circuit comprises forming a sensing unit, a driving unit, and an interconnection circuit therebetween.
