Abstract

The present application discloses a display control method for an LED display system. The LED display device includes a control terminal and multiple sets of cascaded LED modules, and each set of cascaded LED modules includes multiple cascaded LED modules, including: The control terminal performs gamma correction on the display data to obtain grayscale data, the display data has an initial bit width a, and the grayscale data has a first bit width b; compresses the grayscale data to obtain compressed data, and the compressed data has a second bit width m ; Send the compressed data to the cascaded LED modules of the corresponding group. The present application also provides an LED display system, which can reduce the bit width of the display data transmitted between the control terminal and the cascaded LED modules, thereby driving more LED modules with the same bandwidth and increasing the communication bandwidth. Loaded display area.

Description

technical field [0001] The present invention relates to the technical field of LED display, in particular to an LED display system and a display control method thereof. Background technique [0002] LED display systems are widely used to display characters and patterns. The LED display system includes a control terminal and an LED display. The LED module (also known as the unit board) is the main component of the LED display, corresponding to a display area of ​​the LED display. The LED module can be used individually, or multiple LED modules can be cascaded into a group to expand the display area of ​​the display screen. [0003] The console has multiple communication output ports. In the case that the LED display screen contains multiple groups of cascaded LED modules, the control terminal can provide multiple channels of grayscale data to control the corresponding groups of cascaded LED modules respectively. Utilize cascaded LED modules to form scalable displays. [...
