  • Publication number: 20230189560
    Abstract: A display device has a display area with a plurality of light emitting areas and a non-light emitting area between the light emitting areas and a non-display area around a periphery of the display area. The display device includes: a base substrate having a first surface and an opposite second surface; a light emitting element in each of the light emitting areas on the first surface; a light blocking pattern in the non-light emitting area and in a light blocking area of the non-display area; a printed circuit film attached to a pad area of the non-display area on the first surface; and a light blocking layer on the light blocking pattern and the printed circuit film. The pad area is nearer to an end of the base substrate than the light blocking area is, and the light blocking layer includes a black resin and overlaps the light blocking pattern.

  • Patent number: 9530981
    Abstract: A method of sealing a flat panel display device by using laser and a charge-coupled device (CCD) camera. The sealing method includes applying a sealant around a light-emitting unit on a substrate and covering above the light-emitting unit with the encapsulating substrate; irradiating light onto a sealant area to harden the sealant for the first time (first hardening); monitoring a hardening state of the sealant; and further irradiating light onto a region of the sealant in a bad hardening state based on the monitoring result to harden the region of the sealant in the bad hardening state (second hardening). The sealing method may prevent a sealing flaw caused from insufficient laser irradiation dosage, and thus ensure a more stable sealed structure. This may improve quality of the flat-plan-display-device.
