  • Display Module and Display Apparatus
    Publication number: 20240122001
    Abstract: A display includes a polygonal display region and a plurality of non-display portions. The non-display portions are coupled to side edges of the display region in a one-to-one correspondence. At least two of the non-display portions are bent to a back side of the display region. When the non-display portions bent to the back side include adjacent non-display portions, there is an opening between two adjacent non-display portions.

  • Quinone radicals for enriching specific species of carbon nanotubes
    Patent number: 9475701
    Abstract: The present invention is directed to a method for enriching specific species of carbon nanotubes, comprising contacting a composition of carbon nanotubes with one or more quinone compounds, reacting the carbon nanotubes with the quinone compounds, and separating the carbon nanotubes reacted with the quinone compounds from the unreacted carbon nanotubes. The present invention is also directed to a field-effect transistor comprising a semiconducting single-walled carbon nanotube enriched using a method described herein.

  • Method for dispersing carbon nanotubes using chondroitin sulfate cation salt
    Patent number: 9082984
    Abstract: The present invention relates to a method for dispersing carbon nanotubes. The method may include contacting the carbon nanotubes with a solution containing chondroitin sulfate cation salt of formula (I) wherein R1 is MSO3 and R2 is H, or R1 is H and R2 is MSO3; M is an alkaline metal, or an alkaline earth metal further bound to a monovalent counter-anion; n is at least 20.
