  • Patent number: 9704897
    Abstract: A display panel, a preparing method thereof and a display device are provided. The method of preparing a display panel includes steps of: coating an alignment material on both a display region of an array substrate and an electrode region of the array substrate located around a periphery of the display region; aligning the alignment material; assembling the aligned array substrate and an aligned color filter substrate into an assembly; cutting the assembly of the array substrate and the color filter substrate into a plurality of display panel units, such that the electrode region of the array substrate is not covered by the color filter substrate in each of the display panel units; and removing the alignment material covering the electrode region of the array substrate so as to expose the electrode region.

  • Patent number: 8964539
    Abstract: According to the teachings presented herein, a base station implements active queue management (AQM) for uplink transmissions from user equipment (UE), such as a mobile terminal. The base station, e.g., an eNodeB in a Long Term Evolution (LTE) network, uses buffer status reports, for example, to estimate packet delays for packets in the UE's uplink transmit buffer. In one embodiment, a (base station) method of AQM for the uplink includes estimating at least one of a transmit buffer size and a transmit buffer queuing delay for a UE, and selectively dropping or congestion-marking packets received at the base station from the UE. The selective dropping or marking is based on the estimated transmit buffer size and/or the estimated transmit buffer queuing delay.
