摘要： A field emission backlight unit for a liquid crystal display (LCD) includes: a lower substrate; first electrodes and second electrodes alternately formed in parallel lines on the lower substrate; emitters disposed on at least the first electrodes; an upper substrate spaced apart from the lower substrate by a predetermined distance such that the upper and lower substrates face each other; a third electrode formed on a bottom surface of the upper substrate; and a fluorescent layer formed on the third electrode. Since the backlight unit has a triode-type field emission structure, field emission is very stable. Since the first electrodes and the second electrodes are formed in the same plane, brightness uniformity is improved and manufacturing processes are simplified. If the emitters are disposed on both the first electrodes and the second electrodes, and a cathode voltage and a gate voltage are alternately applied to the first electrodes and second electrodes, the lifespan and brightness of the emitters can be improved. The above advantages are also achieved as a result of the method of driving the backlight unit and the method of manufacturing the lower panel thereof.

摘要： An uplink packet data transmission system and method are provided which can reduce a collision probability in a contention period by assigning a priority to mobile stations when bandwidth allocation is rejected due to lack of resources of a base station from which a best effort service is provided. In a method for transmitting best effort data in a communication system, the base station allocates resources to mobile stations for which a reservation has been made in a previous time period when bandwidth for the mobile stations requesting bandwidth allocation is insufficient, reserves bandwidth for mobile stations for which the bandwidth allocation has been rejected, and transmits reservation information. The mobile stations receive the reservation information, skip a next scheduled bandwidth allocation request, and transmit data through bandwidth allocated from the base station.

摘要： A voice packet communication apparatus and method in a wireless communication system are provided. The communication method includes extracting, at a base station, RTP data from an IP packet received from a corresponding terminal in voice packet communication, generating the RTP data as a MAC PDU, and sending the generated MAC PDU to a wireless terminal; and extracting, at the wireless terminal, the RTP data from the MAC PDU received from the base station and reproducing the RTP data through a voice codec. Since the amount of data to be transmitted and received in the radio section is reduced, the present invention can enhance the bandwidth efficiency.
