LED Display Module Segmentation for Parallel Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED display devices experience decreased display speed and visual refresh rate due to increased image resolution, as each display device processes more image data, leading to inefficiencies in processing and display speed.
Innovation Solution
The LED display device divides each LED module into multiple unit blocks, with each unit block containing gate drivers, data drivers, and a display controller that processes image data in parallel and transmits logic signals to drive the LEDs, enhancing processing speed and visual refresh rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image resolution is increased to improve display quality, then display quality is improved, but processing speed decreases
Solution Approach 1:
The LED display device is divided into multiple independently controllable display units, each with its own processing capabilities. This segmentation allows parallel processing of image data across multiple units, maintaining high processing speed while supporting high resolution through the combination of multiple units.
2Measurement precision
If image resolution is increased to improve display quality, then display quality is improved, but visual refresh rate decreases
Solution Approach 1:
By dividing the display into multiple independent units that can be controlled and refreshed separately, each unit can complete its refresh cycle faster. This segmented approach enables higher overall refresh rates even when the total display resolution is high, as not all pixels need to be updated simultaneously across the entire display.
3Speed
If parallel processing is implemented to improve processing speed, then processing speed is improved, but device complexity increases
Solution Approach 1:
The display system is segmented into multiple independent units, each capable of parallel processing. This modular architecture distributes the processing load across multiple simple units rather than requiring one complex processor, achieving parallel processing speed improvements while keeping individual unit complexity manageable.

AI summary
The present disclosure provides an LED display device. The LED display device divides each of LED modules into a plurality of unit blocks. In each of the unit blocks, a display controller transmits image data to be processed in parallel to the corresponding data driver at the same time, and transmits logic signals to the corresponding gate driver, thereby driving the corresponding data driver and then turning on the corresponding LEDs. Therefore, the speed processing the image data of each unit block can be improved, to enhance the visual refresh rate.
