Tiling device including substrates and data driving circuit

A tiling device, comprising:

• a first substrate, comprising a plurality of first semiconductor units;
• a second substrate, comprising a plurality of second semiconductor units;
• and
• a data driving circuit, coupled to the first substrate and the second substrate, and configured to simultaneously provide first data signals to the plurality of first semiconductor units and the plurality of second semiconductor units, and simultaneously provide second data signals to the plurality of first semiconductor units and the plurality of second semiconductor units,
• wherein the first substrate further comprises at least one first data channel for receiving the first data signals,
• wherein the second substrate further comprises at least one second data channel for receiving the second data signals,
• wherein the data driving circuit comprises at least one data pin for providing the first data signals and the second data signals, and
• wherein a number of the at least one data pin is less than a sum of a number of the at least one first data channel and a number of the at least one second data channel.
