Abstract:
A method for patterning crystalline indium tin oxide (ITO) using femtosecond laser is disclosed, which comprises steps of: (a) providing a substrate with an amorphous ITO layer thereon; (b) transferring the amorphous ITO layer in a predetermined area into a crystalline ITO layer by emitting a femtosecond laser beam to the amorphous ITO layer in the predetermined area; and (c) removing the amorphous ITO layer on the substrate using an etching solution.
Abstract:
A treatment system or treatment reactor (1) comprising at least one dielectric barrier discharge lamp (2) with a first electrode (20) and a housing (10) for containing a medium (3) like a fluid and/or a gas and/or a solid material which is to be treated by means of the radiation generated by the lamp (2) is disclosed which is especially characterized in that at least one second electrode of at least one lamp (2) is provided in the form of at least one intermediate counter electrode (3, 4) which is positioned within a volume (31) between at least one dielectric barrier discharge lamp (2) and the housing (10). By this, influences of the treated medium on the electrical behavior of the treatment system or reactor (1) and especially power losses in the medium can be avoided or considerably be decreased. Furthermore, losses of the lamp light due to absorption and/or shadowing at an outer electrode surrounding the lamp are avoided as well.
Abstract:
An anode electrode 10 is composed of a straight elongated cylindrical body, and the outer periphery of the cylindrical body is covered with a dielectric body 12. Further, a cathode portion 20 has a straight semicylindrical shape. A cathode 25 surrounds the anode, and the anode and cathode are disposed parallel to each other in the longitudinal direction. Further, the cathode comprises a cathode wire group 16. Both ends of the cathode wire group are fixed to both ends 20D in the longitudinal direction of the semicylindrical body constituting the cathode portion, so that a plurality of wires become parallel to each other. A reflective surface for reflecting irradiation in a vacuum ultraviolet region is formed on the surface 20S of the cathode portion at the side facing the anode.

Abstract:
A liquid crystal display includes a liquid crystal display panel which has first and second drain lines groups, a control circuit board which has a control unit, a first and second drain drivers groups connected to the corresponding first and second drain lines groups, a back light unit, a metal frame, and a shield member which shields against EMI. Both of the first and second drain drivers groups are arranged at a same peripheral side of the liquid crystal display panel. The control unit supplies first and second signals to the drain drivers groups via flexible printed circuits which are connected to the control circuit board. The control circuit board is sandwiched between the metal frame and the shield member, and the metal frame is arranged between the control circuit board and the liquid crystal display panel.
