1. A splicing screen display device, wherein the splicing screen display device comprises:
display modules comprising a plurality of basic display modules and at least one supplementary display module, wherein the supplementary display module is disposed at a joint of two of the basic display modules;
a processing module connected to the display modules with electrical signals and configured to perform a first process on a received source image frame to obtain a target sub-image frame corresponding to each of the display modules;
a transmitting module connected to the processing module with electrical signals and configured to receive and perform a second process on a target sub-supplemental image frame transmitted by the processing module, wherein the target sub-supplemental image frame is the target sub-image frame corresponding to the supplementary display module, wherein the second process is to further optimize the image quality of the target sub-supplemental image; and
a driving module disposed corresponding to the supplementary display module, and connected to the transmitting module and the supplementary display module with electrical signals,
wherein the driving module comprises a substrate, and a driving unit and a distribution unit integrated on the substrate, the driving unit is connected to the distribution unit with electrical signals, the driving unit is configured to perform a third process on the received target sub-supplemental image frame and transmit the received target sub-supplemental image frame to the distribution unit; and wherein the distribution unit is connected to the supplementary display module with electrical signals, and the distribution unit is configured to receive the target sub-supplemental image frame processed by the driving unit and distributes the target sub-supplemental image frame to a corresponding one of the supplementary display modules for the supplementary display module to display,
wherein the driving module comprises a driving board, and the driving board comprises the substrate, and a port unit, the driving unit, and the distribution unit disposed on the substrate,
wherein the driving board comprises:
a main driving board comprising the substrate, the port unit, the driving unit, the distribution unit, and an expansion connector;
an auxiliary driving board disposed at one side of the main driving board along the joint, and comprising the substrate, the distribution unit, and the expansion connector, wherein the main driving board is docked and fixed to the auxiliary driving board through the expansion connector to realize electrical signal connection,
wherein only the main driving board comprises the driving unit,
and the driving unit is electrically connected to a plurality of display interfaces on both the main driving board and the auxiliary driving board to enable both the main driving board and the auxiliary driving board to emit light.
