The touch display panel 2 is disposed on the substrate 1, and the package board 3 is disposed on the touch display panel 2. The sealing portion 4 is located between the substrate 1 and the sealing plate 3, and seals the touch display panel 2 in a space between the substrate 1 and the sealing plate 3.

In this embodiment, the transparent conductive material is ITO (indium Tin oxide), which is a transparent film material, is an N-type semiconductor, has good conductive performance at room temperature, has good transmittance for visible light, and is commonly used as an anode material in an OLED display device. ITO can walk in a large number directly over encapsulation portion 4, if change ordinary metal and walk the line into ITO and walk the line, then can solve encapsulation portion 4 and marginal routing area 5' among the prior art and dodge thereby occupy the problem of space. However, the impedance of the ITO is relatively large, which may be 500 times the impedance of the metal, and if the ITO traces are used completely, the sensing amount is too small due to the too large impedance, which affects the performance of the entire touch display device. Therefore, in order to control the impedance within a range that can be covered by an IC (Integrated Circuit) and solve the problem of occupying space, the invention overlaps the metal trace 521 and the ITO trace 522 to form a complete overlapping trace 520, thereby solving the problem of avoiding the edge trace region 5' and the package portion 4 in the prior art and achieving the effect of a narrow frame.
