  • Patent number: 7622857
    Abstract: An electron emission display including a first substrate having at least one electron emission device and a second substrate opposite the first substrate. The second substrate is formed with an effective region and a non-effective region. The effective region includes a fluorescent layer for emitting light by collision with electrons emitted from the electron emission device. The non-effective region includes a region in which a light-shielding layer has a transparent conductive layer and a metal layer. The transparent conductive layer is formed in the effective region where the fluorescent layer is absent. The second substrate improves the brightness of light emitted from the fluorescent layer and prevents a power supply layer, to which a high voltage is applied, from being damaged, because the transparent conductive layer is not formed under the effective region.

  • Patent number: 7514858
    Abstract: An electron emission display comprising an electron collector or metal member is provided. The electron emission display comprises an electron emission substrate comprising at least one electron emission device and an image forming substrate comprising at least one emission region and at least one non-emission region. Images are formed in the emission regions by the collision of electrons emitted from the electron emission devices with the emission regions. The image forming substrate further comprises a metal layer positioned on at least the emission regions, and at least one electron collector positioned in the non-emission region. The electron collector may comprise first and second ends, wherein the first end is attached to the image forming substrate and the second end faces the electron emission substrate. The electron collector stabilizes the metal layer and fluorescent layers, thereby reducing arc and maintaining uniform brightness by re-directing scattered electrons toward the fluorescent layers.

  • Patent number: 7251702
    Abstract: In a method of controlling transmitting and receiving buffers of a network controller and a network controller operating under such a method, at least one request for access to a system bus from the transmitting buffer and the receiving buffer is received, and the occupancy level of data in the receiving buffer and the vacancy level of data in the transmitting buffer are determined. Access to the system bus is granted based on the determination result. Buffers in the transmitting and receiving paths are treated as a single virtual transmitting buffer and a single virtual receiving buffer, respectively. Bus priority is determined by the data occupancy level in each virtual buffer and any change in the occupancy level. Therefore, it is possible to prevent or reduce underflow of the transmitting buffer and overflow of the receiving buffer, thereby impartially arbitrating which of the buffers can access the memory.
