Abstract: A peptide biomarker for identifying Hippocampus species based on peptidomics and application thereof are disclosed, belonging to the technical field of biology. The protein in Hippocampus is studied, and the Hippocampus thermostable protein is comprehensively analyzed using a peptidomics method. The analysis discovered potential peptide biomarkers of Hippocampus collagen, the specificity of the potential peptide biomarkers is verified by HPLC-triple quadrupole mass spectrometry, and the peptide biomarkers are comprehensively identified by combining bioinformatics analysis. Finally, 10 peptide biomarkers are discovered, targeting 11 different species of Hippocampus. The markers provided may identify Hippocampus existing in the market, promote the scientific and standardized classification and grading of Hippocampus commodities, and play an important role in high-quality and high-price trade circulation of the Hippocampus commodities.

Abstract: The present invention provides a light guide plate (30) for an electronic paper display and the electronic paper display. The light guide plate (30) is arranged above a display surface of an electrophoretic display module (10), and it comprises a main body, wherein a tooth-shaped pattern is arranged on an in-light surface (33) of the main body. The electrophoretic display module (10) comprises a microcapsule electrophoretic display module or a microcup electrophoretic display module. The tooth-shaped pattern is formed by a plurality of arc-shaped projections (331), arc-shaped recesses (332), angle-shaped projections, or angle-shaped recesses (333).

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.
