Touch panel, touch display apparatus using the same and manufactured method thereof
View Patent ↗A manufacturing method of a touch panel is provided. The method includes the following steps. A conductive layer is formed on a substrate, and a dielectric layer is formed to cover the conductive layer. The conductive layer and the dielectric layer are then patterned to respectively form several sensing wires and several dielectric blocks by using a first mask, which is a half-tone mask. Next, a transparent conductive layer is first formed to cover the conductive layer and the dielectric layer, and is then patterned to form a touch sensing structure by using a second mask.
1. A touch panel, comprising:
a substrate;
a first sensing wire, formed on the substrate;
a dielectric block, formed on the first sensing wire and comprising two through holes, wherein the first sensing wire is exposed from the two through holes; and
a touch sensing structure, covering the dielectric block and extending to the first sensing wire via the two through holes;
wherein, an outer lateral surface of the first sensing wire is connected to an outer lateral surface or an inner lateral surface of the dielectric block, and the first sensing wire and the dielectric block are formed by using the same half-tone mask.
2. The touch panel according to claim 1 , wherein the outer lateral surface of the first sensing wire is substantially aligned with the outer lateral surface of the dielectric block.
3. The touch panel according to claim 1 , wherein the outer lateral surface of the first sensing wire is substantially adhered to the inner lateral surface of the dielectric block.
4. A touch display apparatus, comprising:
a display unit, for providing a display image; and
a touch panel according to claim 1 , disposed adjacent to the display unit, for providing a touch sensing function.
