  • Publication number: 20080266214
    Abstract: An active matrix drive system drives an emissive display device such as an organic light-emitting diode display and is configured to measure sub-pixel current in the emissive display device. One or more power column power lines of the emissive display device are turned off while sub-pixel current is measured. As a result, the sub-pixel current is relative large compared to the background current of the emissive display device, which facilitates accurate measurement of the sub-pixel current.

  • Patent number: 7175494
    Abstract: An electron-emitting device contains a vertical emitter electrode patterned into multiple laterally separated sections situated between the electron-emissive elements, on one hand, and a substrate, on the other hand. The electron-emissive elements comprising carbon nanotubes are grown at a temperature range of 300° C. to 500° C. compatible with the thermal stress of the underlying substrate. The electron-emissive elements are grown on a granulized catalyst layer that provides a large surface area for growing the electron-emissive elements at such low temperature ranges. To ensure growth uniformity of the carbon nanotubes, the granularized substrate is soaked in a pre-growth plasma gas to enhance the surface diffusion properties of the granularized substrate for carbon diffusion.

  • Patent number: 6841003
    Abstract: Carbon nanotubes are formed on a surface of a substrate using a plasma chemical deposition process. After the nanotubes have been grown, a purification step is performed on the newly formed nanotube structures. The purification removes graphite and other carbon particles from the walls of the grown nanotubes and controls the thickness of the nanotube layer. The purification is performed with the plasma at the same substrate temperature. For the purification, the hydrogen containing gas added as an additive to the source gas for the plasma chemical deposition is used as the plasma source gas. Because the source gas for the purification plasma is added as an additive to the source gas for the chemical plasma deposition, the grown carbon nanotubes are purified by reacting with the continuous plasma which is sustained in the plasma process chamber. This eliminates the need to purge and evacuate the plasma process chamber as well as to stabilize the pressure with the purification plasma source gas.

  • Patent number: 6841002
    Abstract: Carbon nanotubes are formed on a surface of a substrate using a plasma chemical deposition process. After the nanotubes have been grown, a post-treatment step is performed on the newly formed nanotube structures. The post-treatment removes graphite and other carbon particles from the walls of the grown nanotubes and controls the thickness of the nanotube layer. The post-treatment is performed with the plasma at the same substrate temperature. For the post-treatment, the hydrogen containing gas is used as a plasma source gas. During the transition from the nanotube growth step to the post-treatment step, the pressure in the plasma process chamber is stabilized with the aforementioned purifying gas without shutting off the plasma in the chamber. This eliminates the need to purge and evacuate the plasma process chamber.
