  • Patent number: 12215580
    Abstract: A differential-pressure sliding sleeve has an outer cylinder with a flow guiding hole being provided in a wall of the outer cylinder, an inner cylinder arranged in an inner cavity of the outer cylinder, an upper joint extending into the outer cylinder and fixedly connected to an upper end of the outer cylinder, a lower joint extending into the outer cylinder and fixedly connected to a lower end of the outer cylinder, and a dissolvable carrier ring arranged between the lower joint and the inner cylinder. An area of the axial upper end surface of the inner cylinder is greater than that of an axial lower end surface thereof, so that the working fluid generates a pressure difference to provide downward pressure for the inner cylinder, which moves downward under the pressure after the carrier ring is dissolved to open the flow guiding hole.

  • Patent number: 10303004
    Abstract: The present disclosure relates to the field of quantum dot display technology and discloses a method for manufacturing a quantum dot display device. The method comprises: providing an array substrate and a counter substrate opposite to each other; printing an alignment solution containing a quantum dot material onto a side of the array substrate facing the counter substrate; removing a solvent in the alignment solution printed onto the side of the array substrate facing the counter substrate; heating the array substrate after removal of the solvent; and providing a backlight source at a side of the array substrate facing away from the counter substrate. The present disclosure further relates to a corresponding quantum dot display device. With such a manufacturing method, the display quality of the resulting quantum dot display device is greatly improved, and the associated manufacturing cost and process difficulty are reduced.

  • Publication number: 20190144987
    Abstract: A mask assembly and manufacturing method thereof are provided. The mask assembly includes: a frame, a first mask and a second mask stacked on the frame. The second mask has at least one evaporation region with each being provided with a plurality of evaporation holes having the same shape. The first mask includes a plurality of cross-arranged sub-masks defining at least one open region. The at least one open region is in one-to-one correspondence to the at least one evaporation region, and includes at least one irregular open region. An orthographic projection of each irregular open region on the second mask is located in a corresponding evaporation region. With the mask assembly, the phenomenon of poor color-mixing during evaporation due to the uneven surface of the second mask can be avoided when the irregular display panel is manufactured, and the display reliability of the manufactured display panel can be improved.

  • Publication number: 20170077442
    Abstract: The embodiments of the present invention provide a packaging structure for OLED device, packaging method and electronic equipment. According to the embodiments of the invention, an anaerobic sealant is applied in the OLED packaging process as a packaging material. Since anaerobic sealant can be cured at room temperature without heat curing or UV curing, the technological process can be simplified, saving the cost. Meanwhile, the OLED process per se should be performed in a vacuum or inert gas environment (i.e., an anaerobic environment), which is advantageous for applying the anaerobic sealant; therefore no more investment is required, and the cost is saved. Moreover, the bonding strength of the cured anaerobic sealant is relatively strong, thus the sealed bonding between the cover plate and the substrate can be realized without an additional dam coating process, simplifying the technological process.
