  • Patent number: 11791351
    Abstract: The present disclosure provides an array substrate and a manufacturing method of the array substrate. In the manufacturing method of the array substrate, during performing a first wet etching and a second wet etching on a second metal layer, the wet etching is stopped when a copper conductive layer is merely etched completely. Because a wet etching speed of a liner layer is slow, an etching time of the wet etching and a CD loss of the copper conductive layer can be greatly reduced, and the CD loss is relatively small. Meanwhile, an entire CD loss of the second metal layer can be reduced, and an aperture ratio can be improved.

  • Patent number: 11764331
    Abstract: In a flip-chip LED assembly having an array of LEDs formed on the same substrate, different LEDs of the array have different distances to the n-contacts of the assembly. This may cause current crowding as current has to spread from the n-contacts through the substrate to each the farthest LEDs of the LED array, requiring LEDs that are farther away to be driven with a higher voltage in order to receive a desired amount of current. To spread current more evenly through the LED assembly and reduce a voltage difference between the closest and farthest LEDs of the array, one or more additional n-contacts are formed within the LED array. In some embodiments, the n-contacts may replace a pixel of the LED array. In other embodiments, one or more p-contacts of the LED array are resized or repositioned to accommodate the additional n-contacts without sacrificing pixels of the LED array.

  • Patent number: 11749787
    Abstract: An array of phosphor pixels is positioned on an array of semiconductor LED pixels with thermally curable adhesive between them. Selected LED pixels of the array are electrically activated; resulting heat cures the adhesive to attach the corresponding phosphor pixel to the activated LED pixel and to release the corresponding phosphor pixel from a carrier. Removal of the carrier removes unattached phosphor pixels, leaving behind phosphor pixels attached to the LED pixels that were activated. The process can be repeated for phosphor pixels of different colors.
