  • Patent number: 12274132
    Abstract: An embodiment of the present application discloses an OLED display device manufacturing method and an OLED display device. The method includes a first pixel definition partitioning bar forming step, a second pixel definition partitioning bar forming step, and a color ink printing step. The first pixel definition partitioning bar forming step includes forming first pixel definition partitioning bars on substrate along a first direction. the second pixel definition partitioning bar forming step includes forming second pixel definition partitioning bars on the substrate along a second direction. An overflow drainage region is defined in each of the second pixel definition partitioning bars. The present application uses the overflow drainage region to perform an overflow drainage color inks printed on the substrate in the color ink printing step to prevent an issue of the overflowing color inks has color mixing and affect a quality of the OLED display device.

  • Publication number: 20240222396
    Abstract: Embodiments of the present application provide an array substrate and a manufacturing method thereof, and a display panel. The array substrate includes a substrate, a source electrode, a drain electrode, a semiconductor layer, and a channel defining layer. The semiconductor layer is disposed between the source electrode and the drain electrode, and the semiconductor layer partially overlaps with the source electrode and the drain electrode. The channel defining layer is disposed around the semiconductor layer, and is correspondingly disposed on the source electrode and the drain electrode. When the semiconductor layer is prepared, the semiconductor layer is directly printed in a printing opening defined in the channel defining layer. Overflow of the semiconductor layer is prevented by the channel defining layer.
