Abstract

The embodiment of the invention discloses an image data transmission method, an image data transmission device, a display controller, a display screen control system and an LED display system. The image data transmission method is suitable for a display controller of a display screen control system, and the display screen control system further comprises a plurality of cascaded module controllers electrically connected with the display controller. The method comprises the following steps: determining one of the plurality of module controllers as a target module controller, and sending a target image line data packet to the plurality of module controllers according to load region coordinate information, load region height and load region width of the target module controller, the target image line data packet comprises recognition information and line packet data of the target module controller, and the data size of the line packet data is equal to the width of the loading region. The embodiment of the invention can solve the problem of bandwidth waste in the prior art.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to an image data transmission method, an image data transmission device, a display controller, a display screen control system and an LED display system. Background technique [0002] In the field of LED display, an LED display control system generally includes a display controller (eg, a sending card) and a module controller (eg, a receiving card) electrically connected via an Ethernet interface of the display controller. The maximum load of the network port of the display controller is generally the corresponding number of pixels calculated according to the network port bandwidth (eg, 1G bandwidth) of the display controller equivalently. For example, the number of pixels corresponding to 1G bandwidth is 650,000. [0003] In practical applications, under the condition that the maximum loading pixels of the network port are certain, the loading capacity of the module control...
