1. A spliced display, comprising:
a transparent substrate having a display surface and a back surface opposite to each other;
a plurality of driving backplanes, disposed on the back surface of the transparent substrate and spliced with each other;
a plurality of micro (light-emitting diodes) LEDs, disposed on the driving backplanes respectively and located between the driving backplanes and the transparent substrate, wherein each of the driving backplanes is corresponding to parts of the micro LEDs; and
a plurality of light sensors, disposed on the transparent substrate and located between the micro LEDs and the transparent substrate, wherein 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 sensors,
wherein the micro LEDs and the light sensors are located on different carriers respectively, wherein the driving backplanes and the transparent substrate form the different carriers respectively,
wherein at least parts of the light sensors and the driving backplanes overlap in a direction perpendicular to the display surface.
