  • Patent number: 10082703
    Abstract: Provided are a liquid crystal display panel, and a composite substrate and a method for fabricating the composite substrate. The composite substrate includes: a substrate, a carbon nanotube layer and a photoalignment matrix material. The carbon nanotube layer is adhered to a surface of the substrate with the photoalignment matrix material; the carbon nanotube layer includes multiple carbon nanotubes extending in a same direction. Multiple grooves arranged in parallel may be formed between carbon nanotubes since the extending direction of the carbon nanotube is the same, and the groove may be used for an initial alignment of liquid crystal molecules, hence the carbon nanotube layer may serve as an alignment layer. In addition, the carbon nanotube has a polarizing feature to serve as a polarizing layer. Therefore, the composite substrate may serve as both the alignment layer and the polarizing layer.

  • Patent number: 9798175
    Abstract: Provided are a liquid crystal display panel, a composite substrate and a method for fabricating the composite substrate. The composite substrate includes: a substrate, multiple electrodes insulated from each other and a carbon nanotube layer arranged on a surface of the substrate. The carbon nanotube layer is divided into multiple blocks insulated from each other in a plane where the carbon nanotube layer is located. Each block includes multiple carbon nanotubes extending in a same direction, and the extending directions of the carbon nanotubes in at least two blocks are different. Each of the electrodes is electrically connected to a respective block of a plurality of blocks.

  • Patent number: 9733495
    Abstract: Polarization glasses are provided. The polarization glasses include a frame, and a first lens and a second lens disposed within the frame. The first lens and the second lens each include a transparent substrate, an optical alignment base material and a carbon nanotube layer; the carbon nanotube layer is adhered to a surface of the transparent substrate through the optical alignment base material; the carbon nanotube layer includes multiple carbon nanotubes extending in a same direction, and the orientation of the optical alignment base material is parallel to the extension direction of the carbon nanotube. Since the carbon nanotube layer has a flat light absorption rate within a wide wave spectrum range, the polarization glasses may efficiently alleviate discomfort of human eyes caused by light, and the carbon nanotube layer may have an absorption and isolation effect on ultraviolet light.
