Abstract:
A thin film circuit comprising:a thin film switching circuit having: an upper circuit layer comprising at least one upper joint; a lower circuit layer comprising at least one lower joint corresponding to the upper joint, wherein the lower circuit layer is set under the upper circuit layer, and an air-filled space is disposed between the upper joint and the lower joint; and at least one first air conduit being set between the upper circuit layer and the lower circuit layer and being connected to the air-filled space; and at least one bus structure being connected to the thin film switching circuit and extending out of the thin film switching circuit to transmit electrical signals of the thin film switching circuit, the bus structure having at least one second air conduit, one end of the second air conduit being connected to ambient atmosphere; wherein another end of the second air conduit is connected to the first air conduit so that the air in the air-filled space can flow in and out to the ambient atmosphere through the first air conduit and the second air conduit.
