Disclosed are a display substrate and a packaging method of the display substrate. The display substrate comprises a substrate, a plurality of light emitting devices, a light absorbing layer, a light transmitting layer, and a transparent protective layer. The plurality of light emitting devices are arranged on the substrate with a spacing region between adjacent light emitting devices; the light absorbing layer is located at least in the spacing region; the light transmitting layer is continuously arranged on the side of the light absorbing layer away from the substrate and the side of the light emitting device away from the substrate; the transparent protective layer is arranged on the side of the light transmitting layer away from the light absorbing layer; wherein the plurality of light emitting devices comprise a first light emitting device, a second light emitting device, and a third light emitting device, the spacing between the first light emitting device and the second light emitting device is smaller than the spacing between the second light emitting device and the third light emitting device, and the difference between the minimum thickness of the light absorbing layer in the spacing region between the first light emitting device and the second light emitting device and the minimum thickness of the light absorbing layer in the spacing region between the second light emitting device and the third light emitting device is less than or equal to 2.0 μm.

This invention provides an image forming apparatus in which, compared to illuminating a light-emitting portion of a discharge end located in a position difficult for surrounding users to visually perceive, residual recording medium on the discharge end can be easily detected by nearby users. The image forming apparatus includes: a first discharge end for discharging recording medium; a second discharge end located in a position even more difficult for surrounding users to visually perceive than the first discharge end; a memory; and a processor, which controls the illumination of a first light-emitting portion located in a position wider than the second discharge end, where residual recording medium is found on the second discharge end.

This utility model discloses a light strip fixing tape with alignment function, belonging to the field of lighting equipment technology, used for fixing light strips. It includes a base film, a high-temperature resistant tape, several black and white adhesive strips, and a positioning film. The base film is a strip-shaped release film; the high-temperature resistant tape is a strip-shaped single-sided adhesive strip; the adhesive surface of the high-temperature resistant tape is attached to the base film; the black and white adhesive strips are block-shaped double-sided adhesive strips; one adhesive surface of the black and white adhesive strips is attached to the non-adhesive surface of the high-temperature resistant tape; several black and white adhesive strips are arranged in a row, corresponding one-to-one with the positions of the light strip's LED beads; the positioning film is a strip-shaped release film; the positioning film is attached to the other adhesive surface of the black adhesive strip; the side of the positioning film has positioning protrusions, which correspond to the LED bead gaps or LED bead positions in the light strip, i.e., the positioning protrusions are aligned or staggered with the black and white adhesive strips. This utility model can achieve precise alignment between the LED bead gaps and the black and white adhesive strips, avoiding the problem of overlap between the black and white adhesive strips and the LED bead areas.
