  • Patent number: 12205520
    Abstract: A splicing screen includes a connecting plate and two sub-displays. The sub-display screens include gate signal lines, data lines, and first pads, each of which is electrically connected to a data line or a gate signal line. The connecting plate is arranged on one side of the sub-display screen facing away from a light-emitting side thereof. Two first pads connected to the data lines or gate signal lines of two sub-display screens that are spliced are connected in pair by the connecting plate. By utilizing pads and the connection plate to achieve a communication between the signal lines in the sub-display screens without needing, a drive circuit at an edge of each sub-display screen, a width of the non-display area at the splicing slit is reduced. The first pads are provided at one side of the sub-display screen facing the connecting plate, which reduces the width of the splicing slit.
