  • Publication number: 20240298479
    Abstract: A display panel includes a substrate, an insulating layer arranged at one side of the substrate, a conductive adhesive layer arranged at one side of the insulating layer away from the substrate, and a chip arranged at one side of the conductive adhesive layer away from the substrate. The insulating layer is provided with an accommodation groove, and first electrodes are arranged within the accommodation groove. Along a direction perpendicular to a plane where the substrate is located, an orthographic projection of the conductive adhesive layer on the substrate covers an orthographic projection of the accommodation groove on the substrate. Part of the conductive adhesive layer is in contact with the first electrodes, and the chip is in contact with the conductive adhesive layer. A channel is provided in the insulating layer for the accommodation groove to communicate with outside.

  • Patent number: 10633271
    Abstract: A zero discharge process for separating sludge and salt from desulfurization wastewater includes a pretreatment process, a membrane treatment process and an evaporative crystallization process; in the pretreatment process, the desulfurization wastewater enters a raw water tank, an aeration fan introduces compressed air into the raw water tank, and the wastewater is lifted to first-stage reaction and clarification by a raw water pump; in the membrane treatment process, the incoming wastewater is first filtered by ultrafiltration, then enters a pH adjustment tank, and is pumped into a nanofiltration membrane separation system and a reverse osmosis membrane separation system; in the evaporative crystallization process, the incoming wastewater is first subjected to two-stage preheating, then enters a degasser, and finally enters an evaporative concentration system and a crystallization system.
