  • Patent number: 11930663
    Abstract: A display panel includes a first substrate, pixel structures, a first common pad, a second substrate, a second common electrode, a display medium and a conductive particle. The pixel structures are disposed on an active area of the first substrate. The first common pad is disposed on a peripheral area of the first substrate, and is electrically connected to first common electrodes of the pixel structures. The second common electrode is disposed on the second substrate. The conductive particle is disposed on the first common pad, and is electrically connected to the first common pad and the second common electrode. The conductive particle includes a core and a conductive film disposed on a surface of the core, where the conductive film has a main portion and raised portions, and a film thickness of each of the raised portions is greater than a film thickness of the main portion.

  • Publication number: 20230160194
    Abstract: An automatic sewage regulation system and a regulating method are provided. The automatic sewage regulation system is disposed between preset sewage sources and a preset sewage treatment apparatus and includes an equalization tank and an automatic sewage regulating device. The automatic sewage regulating device includes sensing modules for sensing and transmitting water quality sensing values of sewage in the preset sewage sources to a control module which outputs regulating signals to water flow regulators, so that the water flow regulators can regulate flowing volumes of the sewage of the preset sewage sources according to the regulating signal, to keep a water quality sensing value of the sewage in the equalization tank within a preset range, thereby preventing the equalization tank from converging sewage having excessively-high or excessively-low water quality sensing value. As a result, burden of a preset sewage treatment apparatus can be reduced.

  • Publication number: 20200378105
    Abstract: An automatic sewage regulation system and a regulating method are provided. The automatic sewage regulation system includes buffer tanks, an equalization tank, a sewage treatment apparatus and an automatic sewage regulating device. The automatic sewage regulating device includes sensing modules for sensing and transmitting water quality sensing values of sewage in the buffer tanks to a control module which outputs regulating signals to water flow regulators, so that the water flow regulators can regulate flowing volumes of the sewage of the buffer tanks according to the regulating signal, to keep a water quality sensing value of the sewage in the equalization tank within a preset range, thereby preventing the equalization tank from converging sewage having excessively-high or excessively-low water quality sensing value. As a result, burden of the sewage treatment apparatus can be reduced, and the lifetime of the sewage treatment apparatus can be extended.
