  • Patent number: 12211967
    Abstract: A light-emitting display device includes at least a transparent substrate, a first patterned conductive layer and a second patterned conductive layer respectively disposed on top of the opposite first and second surfaces of the transparent substrate, and a plurality of inorganic electroluminescent objects disposed in form of an array on top of the first surface of the transparent substrate with the inorganic electroluminescent objects being spaced from one another in a distance of at least 2 mm. Each of the inorganic electroluminescent objects has one power pin and light signal pins for red light, green light, and blue light. The transparent substrate has a plurality of through holes between the first surface and the second surface. The first patterned conductive layer has a plurality of soldering pad regions respectively in connection with the power pin and the light signal pins.

  • Patent number: 12040438
    Abstract: A light-emitting display device has a substrate, at least four electrically isolated soldering pad regions, and a plurality of light-emitting assemblies. The minimum distance between the light-emitting assemblies is at least 2 mm. The soldering pad regions are correspondingly in electrical connection with the input voltage pin, the data signal input or output pin, the clock signal input or output pin, and the ground pin of one of the light-emitting assemblies. The soldering pad region which is in electrical connection with the input voltage pin is electrically connected with a first grid wiring, the soldering pad region which is in electrical connection with the ground pin is electrically connected with a second grid wiring, and the soldering pad region which is in electrical connection with the data signal input pin, the data signal output pin, the clock signal input pin, or the clock signal output pin is electrically connected with a slender wire.

  • Patent number: 8073264
    Abstract: An image-based technique for shredded document reconstruction includes the steps of: employing an image processing process to obtain shred images of the shredded document, and then extracting several features of shred images for reconstruction with two similarity measures, and then employing an algorithm using the shred coding scheme and average word length that is insensitive to the shredding noise on image boundaries, and then a weighted digraph is then carried out to derive the optimal shred sorting result for document reconstruction in terms of the shortest path. Experiments are presented for both the synthetic and real data sets. The results show that the proposed method has correctly merged the majority of the shredded document.
