The embodiment of the application provides a driving system of a display device and a driving method of the display device. The following are detailed descriptions. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a driving system of a display device according to an embodiment of the present disclosure. As shown in fig. 1, a driving system 10 of a display device provided in an embodiment of the present application includes a display panel 101, a driving control board 102, and a programmable logic controller 103. The driving control board 102 is provided with a field programmable gate array chip 1021 and a timing control chip 1022, and the timing control chip 1022 includes a master timing control chip 1023 and a plurality of slave timing control chips 1024.
The programmable logic controller 103 is configured to process the initial image data to divide the initial image data into a plurality of partition image data, and transmit the plurality of partition image data to the master timing control chip 1023 and the plurality of slave timing control chips 1024.
It should be noted that the programmable logic controller 103 is mainly configured to convert the initial image data with low resolution and low refresh rate into the image data with high resolution and high refresh rate, and divide the image data into a plurality of sets of partitioned image data, each set of partitioned image data corresponds to a different display area, where the number of sets of partitioned image data matches the number of the timing control chips 1022. For example, if the initial image data received by the programmable logic controller 103 is 10bit data of 4k × 2k, the programmable logic controller 103 converts the 10bit data of 4k × 2k into 10bit data of 8k × 4k, divides the 10bit data of 8k × 4k into four pieces of partitioned image data, and transmits the four pieces of partitioned image data to the corresponding timing control chip 1022. When the plc 103 transmits the tile image data to the timing controller 1022, the master timing controller 1023 also serves as a timing controller and receives a piece of tile image data.
The display area of the display panel 101 includes a plurality of sub-display areas arranged adjacently, and the timing control chip 1022 controls one corresponding sub-display area respectively and generates a timing signal for driving the display panel 101 to display to the sub-display area controlled by the timing control chip 1022.

The timing control chips 1022 controlling the sub-display regions arranged adjacently receive the edge video data between the sub-display regions arranged adjacently. It should be noted that, by enabling the timing control chips 1022 controlling the adjacently disposed sub-display areas to receive the edge video data between the adjacently disposed sub-display areas, the display area of the display panel can be smoother, and the split screen phenomenon can be avoided. In addition, in the embodiment of the present application, the programmable logic controller 103 directly transmits the edge video data to the corresponding sequential control chip 1022, so that data transmission between adjacent sequential control chips 1022 is not required.
The master timing control chip 1023 is configured to receive the tile image data, generate a synchronization signal according to the tile image data, and transmit the synchronization signal to the fpga chip 1021. The field programmable gate array chip 1021 is used for receiving the synchronization signal and transmitting the synchronization signal to the slave timing control chip 1024. The slave timing control chip 1024 is used for receiving a synchronization signal and partition image data. The master timing control chip 1023 and the slave timing control chip 1024 are also used for transmitting the partitioned image data to the display panel according to the synchronization signal, so as to synchronously drive the display panel to display.
It should be noted that, in the embodiment of the present application, the field programmable gate array chip 1021 copies the synchronization signal generated by the master timing control chip 1023 into multiple copies, and transmits the copies to the slave timing control chip 1024, so that when the master timing control chip 1023 and the slave timing control chip 1024 drive the display panel to display, synchronous driving can be implemented, thereby avoiding the occurrence of a drawing exception phenomenon, and improving the display quality of the display panel.
