  • Publication number: 20240038153
    Abstract: The present disclosure provides an electronic device and a display panel. The display panel includes a transition display region and a transparent display region. First pixel driving circuits are placed in the transition display region. Dummy pixel driving circuits are placed in the transition display region. One of the dummy pixel driving circuit is adjacently placed within a predetermined distance from at least one side of the first pixel driving circuits arranged along the second direction. This could reduce the environment difference between the pixel driving circuit close to the light sensing region and the pixel driving circuit inside the transition display region and thus reduce the luminance difference between the first display pixels controlled by the pixel driving circuit close to the light sensing region and the first display pixels controlled by the pixel driving circuit inside the transition display region.

  • Patent number: 11884603
    Abstract: The present invention utilizes a high-speed intensive mixer in a fluidizing-type, solid-phase, neutralization reactor to blend solid-state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste-like formation, extrusion, granulation, drying, and grinding, etc. The invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, plant space, and labor and energy costs. All of these factors coupled with increased productivity will drastically lower the overall production cost. Also, the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues.
