Problems solved by technology

[0004] If the resolution of the desired display screen 2 is larger, or the resolution of the available sub-display D' is smaller, the number of required sub-display D' will increase
Correspondingly, more data transmission channels need to be provided, and the design complexity of the video distributor 1 will also increase.

Abstract

The invention provides a display device and a display control method. The display device comprises a plurality of sub display screens arranged in an array and connected via a display channel, whereineach sub display screen comprises: a data extraction module use for receiving display data, extracting a display data sub-portion corresponding to the display screen from the received display data, providing the display data sub-portion for a driving module, marking the display data sub-portion corresponding to the display screen in the display data as invalid and providing the display data sub-portion for a downstream sub display screen; the driving module used for performing display driving by using the display data sub-portion from the data extraction module; and a display module for displaying under the drive of the driving module. The display data can be automatically allocated among the sub display screens, so that the design of a video allocator can be simplified, and the allocationof the display data of the sub display screens can be accomplished without the video allocator.

Description

technical field [0001] The present disclosure relates to the technical field of display control, in particular to a display device and a display control method. Background technique [0002] With the development of display technology, people have higher and higher requirements for image quality. One of the most important points is that the resolution of images is getting higher and higher, which has developed from Full High Definition (FHD, Full High Definition) (1920×1080) to 4K (3840×2160), and even to 8K (7680×4320). As resolutions increase, it becomes increasingly difficult to display on a single, independent display. Specifically, a higher resolution of an image generally means that a larger size of the display screen is required, which tends to lower the product yield of the display screen. Therefore, usually a plurality of sub-display screens with low resolution are spliced ​​and assembled together to form a display screen with high resolution. [0003] figure 1 A...
