  • Publication number: 20250085577
    Abstract: A display panel includes an array substrate and a color filter substrate, where the color filter substrate includes a first substrate, spacer pillars, and color filter layers, each spacer pillar is in the spacing region, and each pixel region is provided with a color filter layer. Each spacer pillar includes at least one spacer layer each made of the same material as the color filter layer in one of the pixel regions. The array substrate includes a second substrate and a support layer, where the support layer is on a side of the second substrate facing the color filter substrate, and includes a body layer and a plurality of protrusions on a side of the body layer away from the second substrate, where each protrusion is each opposite to at least one of the spacer pillars. At least one of the spacer pillars is each supported on the corresponding protrusion.

  • Patent number: 10161468
    Abstract: The present invention provides a two-stage stiffness type elastomer combined device, including at least one small-stiffness elastic element and a large-stiffness elastic element, wherein the small-stiffness elastic element is arranged in an elastomer pre-compression device and is serially arranged with the large-stiffness elastic element under the action of a pre-compression load F1. The device has combined stiffness being hard at first and then becoming soft and is used as an elastic axle box suspension device of a railway vehicle, effectively solving the contradiction that a linear snaking critical operation speed of the vehicle and curve passing performance of the vehicle cannot be compromised.
