  • Patent number: 12250142
    Abstract: A method is applied to a network comprising a first area and a second area. A first node in the first area obtains aggregated routing information, where the aggregated routing information is obtained by aggregating a plurality of pieces of original routing information, the plurality of pieces of original routing information correspond to N nodes in a network segment, the N nodes in the network segment have a same flexible algorithm flex-algo, and the aggregated routing information carries an algorithm identifier used to indicate the flex-algo and a network segment identifier used to indicate the network segment. The first node sends the aggregated routing information to the second area, where the aggregated routing information is used to indicate a node in the second area to send a packet to the N nodes in the network segment based on the aggregated routing information.

  • Patent number: 9759976
    Abstract: An electrophoretic display medium and preparing method thereof. The electrophoretic display medium comprises: negatively or positively-charged pigment particles; neutral pigment particles with colors different from the charged pigment particles; and low-polar and/or non-polar dispersing solvent. The method of preparing the electrophoretic display medium comprises: synthesizing neutral pigment particles; synthesizing charged pigment particles; and preparing electrophoretic display medium. The method of synthesizing the neutral pigment particles comprises: mixing together pigment particles, macromonomers, coupling-agents and chain-initiators for polymeric reaction in the solvent, and reacting at a temperature of 30-120° C. for 4-48 hours. The method is applied to many kinds of inorganic oxides, inorganic salts and complex inorganic salt pigments.

  • Patent number: 9318059
    Abstract: The present invention discloses an electrophoretic display and a driving met hod thereof, comprising: arranging each pixel electrode in the electrophoretic display to correspond to a pixel; determining a driving waveform of the electrophoretic display based on the initial gray level and the final gray level of the pixel, applying a display signal of the driving waveform to the pixel electrode, controlling the pixel whose gray level value needs to be changed; wherein the driving waveform comprises at least one gray level driving procedure, each driving procedure corresponds to a gray level changing direction, the final gray level is a gradually changing gray level in the gray level changing direction which the last driving procedure corresponds to. The present invention can realize relatively accurate control to the gray level change while keeping DC balance by means of the electrophoretic display and the driving method thereof when the screen is refreshed.
