  • Publication number: 20240118741
    Abstract: A power source module for powering a motherboard comprises a rectifier circuit, a controlling unit, and a leakage protection circuit. The rectifier circuit electrically connected with the motherboard converts the input voltage into the first voltage configured for powering the motherboard. The controlling unit electrically connected with the motherboard outputs the control signals based on an operation state of the motherboard. The leakage protection circuit electrically connected with the controlling unit guides the control signals into a signal line before the motherboard being powered. The leakage protection circuit avoids the control signals to the component of the motherboard, and an operation time sequence of the component is not disturbed before being powered. A power distribution board and a server system are also disclosed.

  • Patent number: 10908331
    Abstract: A display substrate and a manufacturing method thereof, and a display panel are provided. The display substrate includes a base substrate with a black matrix BM disposed thereon. The base substrate is provided with a display area and a non-display area, and the BM disposed in the non-display area comprises a first BM portion and a second BM portion. The first BM portion and the second BM portion are sequentially arranged in a direction away from the center of the base substrate, and a gap exists between the first BM portion and the second BM portion. When an external electric field exists around the display substrate, the second BM portion can effectively shield the external electric field, thereby effectively preventing the external electric field from affecting the display area of the display panel. Thus, the display effect of the display substrate is improved.

  • Publication number: 20160003448
    Abstract: A color filter layer, a color film substrate including the color filter layer, and a display apparatus including the color filter substrate are provided. The invention relates to the field of display technology and can solve the problem that the color membrane substrates in the prior art have a relatively low utilization ratio of light. The color filter layer of the invention comprises a filter membrane and a light conversion layer disposed on the light entering side of the filter membrane. According to the invention, the light of other frequencies in incident light can be converted into light having the same spectral characteristics as the respective filter membranes, due to the presence of the light conversion layer. Therefore, the utilization ratio of light and the display brightness can be improved, and thus energy consumption can be saved effectively and the display performance can be enhanced.
