Abstract: A display substrate is provided. The display substrate includes a respective encapsulated unit and a separation structure substantially surrounding the respective encapsulated unit. The respective encapsulated unit includes a color conversion layer comprising one or more color conversion blocks; and a respective encapsulating block in an encapsulating layer encapsulating the one or more color conversion blocks. The encapsulating layer is at least partially absent in a peripheral region around the respective encapsulated unit.

Abstract: Provided are a display substrate and a manufacturing method thereof, and a visible light communication apparatus. The display substrate includes a substrate, and the substrate includes a display region and a peripheral region surrounding the display region; the peripheral region includes a visible light signal receiving region surrounding the display region; the display substrate further includes a photosensitive sensing unit, the photosensitive sensing unit is located in the visible light signal receiving region and is configured to receive a visible light signal and convert the visible light signal into an electrical signal to achieve visible light communication.

Abstract: A mask plate includes a plurality of first supporting and shielding strips, and a plurality of second supporting and shielding strips. The second supporting and shielding strips and the first supporting and shielding strips perpendicularly intersect. The first supporting and shielding strips and the second supporting and shielding strips are provided with at least one objective supporting and shielding strip, and an edge of a predetermined surface of the objective supporting and shielding strip parallel to an extending direction of the objective supporting and shielding strip is provided with a thinned area; the thinned area extends in the extending direction of the objective supporting and shielding strip, and has a thickness smaller than a thickness of other areas except the thinned area; and the predetermined surface is a surface of the objective supporting and shielding strip facing a deposition material when a mask evaporation is performed through the mask plate.

Abstract: Embodiments of the present disclosure provide a method of manufacturing a mask, a mask and an evaporation method with a mask. The method comprises: providing a frame and a mask body; and fixing the mask body to the frame to form the mask in a case where at least one of the mask body and the frame is at a predetermined temperature, such that the mask body is elastically deformed by a predetermined amount by tensioning the mask body by the frame by a thermal deformation at a usage temperature different from the predetermined temperature.

Abstract: The present invention discloses a blind bolt fastening device, and belongs to the technical field of bolts. The blind bolt fastening device includes Z-shaped gaskets, a fixed plate, elastic hinges, a screw cap, a nut, an integrated gasket and the like. The top end of the screw cap is connected to the fixed plate in a spot welding manner. A plurality of elastic hinges is uniformly mounted on the fixed plate. One end of each elastic hinge is rotatably fixed on the fixed plate. Connection points of the elastic hinges and the fixed plate do not exceed the outer edge of the fixed plate. The other end of each elastic hinge is connected to one Z-shaped gasket in a spot welding manner. In an initial state, the plurality of Z-shaped gaskets are uniformly distributed and fitted onto the outer wall of the screw cap along a circumferential direction.

Abstract: The present disclosure relates to a measurement tool, for measuring the thickness of an evaporated film at a particular position on a large-sized substrate. The measurement tool includes: a measurement part, having at least one measurement surface onto which at least one sampling substrate sheet is positional and fixable; and a support part connected with the support part and configured to be supportable on an edge frame of a mask so as to place the measurement part in an inside of the edge frame of the mask through the support part. The present disclosure also relates to a method of measuring a thickness of an evaporated film of a large-sized substrate by using the above measurement tool.
