Abstract: An image compensation device including a substrate and island display units is provided. The substrate includes a central area and configuration rings surrounding the central area and spaced apart from the central area at different intervals. The island display units are disposed on the substrate. One of the island display units is disposed at the central area, and the other island display units are respectively disposed at the configuration rings. Each island display unit includes a real display area and a dummy display area located around the real display area, and includes real pixels and dummy pixels. The real pixels are disposed in the real display area. The dummy pixels are disposed in the dummy display area, and a number of the dummy pixels is greater than a number of the real pixels to compensate for a display image spliced by discrete images.

Abstract: A spliced display including a transparent substrate, a plurality of micro (light-emitting diodes) LEDs, and a plurality of light sensors is provided. The transparent substrate has a display surface and a back surface opposite to each other. The driving backplanes are disposed on the back surface of the transparent substrate to be spliced with each other. The micro LEDs are disposed on the driving backplanes respectively and located between the micro LEDs and the transparent substrate. Each of the driving backplanes is corresponding to parts of the micro LEDs. The light sensors are disposed on the transparent substrate and located between the driving backplanes and the transparent substrate. Each of the light sensors is adjacent to at least two of the micro LEDs, and at least one of the at least two of the micro LEDs is adjacent to two of the light sensor.

Abstract: A spliced display including a transparent substrate, a plurality of light emitting diode modules, at least one control element and a signal transmission structure is provided. The transparent substrate has a display surface and a back surface opposite to each other. The light emitting diode modules are disposed on the back surface of the transparent substrate to be spliced with each other. Each of the light emitting diode modules includes a driving backplane and a plurality of micro light emitting diodes, and the micro LEDs are disposed in an array between the driving backplane and the transparent substrate. The control element is disposed on the transparent substrate. The control element is connected to the light emitting diode modules via the signal transmission structure, and the light emitting diode modules are connected to each other via the signal transmission structure.
