The data forwarding units 123 of the other connected driving controllers 100 receive the multimedia data and transmit the multimedia data to the decoding unit 121 for decoding.

Specifically, the present embodiment is suitable for a scenario in which a plurality of drive controllers 100 are spliced for use.

Specifically, the present embodiment is suitable for a scenario in which a plurality of drive controllers 100 are spliced for use. When the plurality of driving controllers 100 are connected together, each driving controller 100 needs to send partial multimedia data of the same frame to the corresponding display 300, and therefore needs to send a frame synchronization signal to the other driving controllers 100 through the synchronization unit 124, so that the plurality of connected driving controllers 100 can send different partial data of the same frame to the corresponding display 300, and the plurality of display 300 can cooperatively display a complete frame of picture.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a driving control device according to an embodiment. In one embodiment, as shown in fig. 5, a drive control apparatus 10 is provided that includes a plurality of drive controllers 100. The drive controller 100 of the present embodiment may refer to the description of any of the above embodiments, which is not repeated herein.

In the present embodiment, each driving controller 100 drives one display panel 300 correspondingly, and the driving control apparatus 10 of the present embodiment can increase the driving upper limit by driving the corresponding display panel 300 by the driving controllers 100 respectively.

Specifically, each drive controller 100 has a drive upper limit, for example, to support a display with 320 × 320 resolution and 60fps (frame rate), which means that each card can drive the display 300 only within 320 × 320 resolution. The drive controller 10 of the present embodiment connects a plurality of drive controllers 100 to realize linkage, thereby driving a screen with higher resolution and frame rate.

For example, if each driver controller 100 supports a display with a resolution of 320 × 320 and 60fps, when a display with a resolution of 640 × 320 is to be driven, the display with a resolution of 640 × 320 can be realized by two driver controllers 100 supporting the resolution of 320 × 320.

Referring to fig. 6, fig. 6 is a schematic structural diagram of another driving control device according to an embodiment. In one embodiment, when the drive controller 100 includes the storage medium interface 140, in order to increase the drive frame rate of the drive controller 100, each drive controller 100 is configured with one storage medium 200, and the plurality of drive controllers 100 acquire the display data through the respectively configured storage media 200.

In this embodiment, specifically, each driving controller 100 is configured with a preset address in advance, and the preset address corresponding to the driving controller 100 is related to the position of the driven display screen 300 on the display screen. The plurality of driving controllers 100 respectively transmit display data matched with a preset address to the display screen 300, thereby achieving a high frame rate display effect. In this embodiment, only the frame sync signal is communicated between the driving controllers 100, for example, the frame sync signal 0000001 is forwarded between the driving controllers 100, and the plurality of driving controllers 100 simultaneously parse the first frame display data.

In the present embodiment, by configuring one storage medium 200 per drive controller 100, it is possible to achieve an increase in the frame rate of the display screen. In addition, not only is the frame rate solved, but also because many decoding algorithms are added on the display at present, for example, the high-bit-rate high-color-gamut display not only displays 8-bit RGB colors, but also enters 10-bit or even 16-bit high-color-gamut, so that the data volume is further increased and the HDR algorithm and the like cause the over-heavy load of the host computer and the over-large data transmission volume, so that the real effect cannot be displayed. The driving control apparatus 10 of the present embodiment can improve the display effect by connecting a plurality of driving controllers 100, and each driving controller 100 drives one display screen 300.

It should be noted that the multimedia data stored in the storage medium 200 in this embodiment may be complete multimedia data or cut multimedia data. The cutting of the multimedia data may be performed according to a position of the display screen 300, which is driven by the driving controller 100, on the display screen.

It is understood that when the storage medium 200 is integrated in the drive controller 100, the storage medium 200 in each drive controller 100 stores multimedia data in advance.

Referring to fig. 7, fig. 7 is a schematic structural diagram of another driving control device according to an embodiment. In one embodiment, to ensure the integrity of the display, a plurality of driving controllers 100 are connected in sequence by respective synchronizing units 124. The frame synchronization signal can be forwarded between the synchronization units 124 connected in sequence, thereby ensuring the integrity of the picture display.

With continued reference to fig. 7, in one embodiment, a plurality of drive controllers 100 are connected in sequence by respective data forwarding units 123.

Specifically, when some of the plurality of driving controllers 100 can acquire the multimedia data, the multimedia data can be forwarded through the data forwarding units 123 connected in sequence, so that each driving controller 100 can normally drive the corresponding display screen 300 to display.

In this embodiment, after acquiring the multimedia data, the processing module 120 of the drive controller 100 only needs to process a part of the multimedia data that needs to be driven, and the remaining multimedia data or all multimedia data may be forwarded to other drive controllers 100. While the plurality of driving controllers 100 forward the multimedia data through the data forwarding unit 123, the synchronization unit 124 may also forward the frame synchronization signal, so that the display total screen formed by the display screens 300 corresponding to the plurality of driving controllers 100 may normally display a complete frame of picture.

It is understood that whether each drive controller 100 is configured with one storage medium 200 may be determined as necessary, that access to the storage medium 200 may be reduced to reduce the cost but not to achieve the highest frame rate display, and that configuring one storage medium 200 per drive controller 100 may achieve the best picture display at the high frame rate.
