Display device and driving method for reducing dark zones around frame area of display screen

A display device, comprising:

• a first substrate, comprising a first signal input side, wherein the first substrate comprises:
• a plurality of first display units;
• a plurality of first signal lines, respectively extending from the first signal input side and respectively electrically connected to at least one of the plurality of first display units;
• a plurality of gate signal lines, located on a different layer from the plurality of first signal lines and respectively extending in a direction transverse to the plurality of first signal lines, wherein each of the plurality of first signal lines is respectively electrically connected to one of the plurality of gate signal lines and then a portion of the plurality of first display units arranged along the corresponding one of the plurality of gate signal lines;
• a plurality of second display units, wherein each of the plurality of second display units is of a display mechanism different from each of the plurality of first display units;
• and
• a plurality of second signal lines, respectively extending from the first signal input side and respectively electrically connected to at least one of the plurality of second display units;
• and
• a second substrate, at least partially stacked with the first substrate and comprising a second signal input side corresponding to the first signal input side to perform inter-substrate signal transmission from the first signal input side to the second signal input side, wherein the second substrate comprises:
• a plurality of third display units;
• and
• a plurality of third signal lines, respectively extending from the second signal input side and respectively electrically connected to at least one of the plurality of third display units,
• wherein a vertical projection range of the plurality of third display units on the first substrate is not overlapped with the plurality of second display units.

A method for driving a display device, comprising the following steps:

• inputting a first signal from a first signal input side of a first substrate through a first signal line and then through a gate signal line extending in a direction transverse to the first signal line to a portion of a plurality of first display units arranged along the gate signal line on the first substrate;
• inputting a second signal from the first signal input side of the first substrate to at least one of a plurality of second display units on the first substrate, wherein each of the plurality of second display units is of a display mechanism different from each of the plurality of first display units;
• and
• inputting a third signal from the first signal input side and performing inter-substrate signal transmission between the first signal input side and a second signal input side of a second substrate at least partially overlapped with the first substrate so as to transmit the third signal to the second signal input side to drive a plurality of third display units on the second substrate, wherein the second signal input side corresponds to the first signal input side, and a vertical projection range of the plurality of third display units on the first substrate is not overlapped with the plurality of second display units.
