Abstract: An array substrate, a manufacturing method thereof, and a liquid crystal display panel are provided. The array substrate includes a substrate, a transparent oxide electrode, an interface protection layer, and a first insulating layer. The transparent oxide electrode is disposed on a side of the substrate. The interface protection layer is disposed on a side of the transparent oxide electrode away from the substrate. The first insulating layer is disposed on the interface protection layer.

Abstract: A method and a furnace for electrical calcination enables utilization of volatile matters of petroleum coke or anthracite during electrical calcination, i.e. conventional calcination or semi-graphitization. The furnace includes an anode, a cathode, and a furnace body. The furnace body includes an annular inner wall, an annular fume duct disposed circumferentially outside of the annular inner wall, an annular outer wall for heat preservation disposed circumferentially outside of the annular fume duct, and an air passage disposed in the annular outer wall. The air passage is in communication with the fume duct and outer atmosphere, respectively. An outlet opening for the volatile matters, in communication with a hearth of the furnace body, is disposed in the fume duct. The combustible volatile matters of the petroleum coke, anthracite, or other raw material are sufficiently utilized during electrical calcination, therefore the energy is saved and the environmental pollution is reduced.
