  • Publication number: 20250133068
    Abstract: An encrypted communication method and apparatus, a device, and a medium are disclosed. The method includes: a first protocol layer of a first party obtains a MAC address of a second party according to a data transmission request from an application layer, the data transmission request including an NLP address of the second party; the first protocol layer generates a first temporary key pair including a first temporary public key and a first temporary private key; the first protocol layer obtains a second temporary public key of the second party according to the first temporary public key; the first protocol layer generates a shared key according to the second temporary public key and the first temporary private key; the first protocol layer determines a data message, the data message carrying encrypted data obtained by encrypting using the shared key, and the receiver of the data message being the second party.

  • Patent number: 12008947
    Abstract: A pixel includes a light emitting element, a first transistor connected to the light emitting element, a second transistor connected between a data line and a first electrode of the first transistor, a third transistor connected between a gate electrode of the first transistor T1 and a second electrode of the first transistor, a fourth transistor connected between a gate electrode of the first transistor and an initialization power source, and a storage capacitor connected between the first power source and the gate electrode of the first transistor. A voltage provided through the data line is time divided into a data voltage provided to the gate electrode of the first transistor when both the second and third transistors turn on, and an on-bias voltage provided to the first electrode of the first transistor when the second transistor turns on and the third transistor turns off.

  • Patent number: 11825600
    Abstract: Provided are a printed circuit board, a display device and a method of manufacturing a display device. The printed circuit board includes a base film including a first surface and a second surface, lead lines disposed on the first surface of the base film, and a first cover layer that covers at least a part of the lead lines and includes fill-in portions disposed between the lead lines. Each of the fill-in portions has a surface height less than a surface height of each of the lead lines with respect to the first surface of the base film.

  • Patent number: 8321747
    Abstract: An efficient general QC-LDPC code decoder includes a general-purpose processor for distributing the storage storage space of the data memory block, and establishing an index for data addressing; a data memory block for storing the information used during decoding; a hardware accelerator for conducting part or all of the information processing operations including parity check, check node updating and variable node updating. A corresponding QC-LDPC code decoding method includes initializing the variable node information and performing parity check on the check matrix row block by row block; updating the check node row block by row block and updating the variable node column block by column block if any check equation is not met.
