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 display device including a circuit substrate, a plurality of pixels, and a light-shielding layer is provided. The pixels include a plurality of light-emitting elements. The light-emitting elements are disposed on the circuit substrate and are electrically connected to the circuit substrate. The light-emitting elements in the pixels are arranged along an arrangement direction. The light-shielding layer is disposed on the circuit substrate and has a plurality of pixel apertures. The pixels are disposed in a corresponding pixel aperture. The light-shielding layer includes a plurality of first light-shielding patterns extending in the arrangement direction and a plurality of second light-shielding patterns connected to the first light-shielding patterns. The extending direction of the second light-shielding patterns is different from the extending direction of the first light-shielding patterns. A thickness of the first light-shielding patterns is greater than or substantially equal to a thickness of the second light-shielding patterns.
