Engineering Contradiction Analysis
1Measurement precision
If a single high-resolution timing control circuit is used to achieve 8K4K display, then display resolution is improved, but development cost and device complexity increase significantly
Solution Approach 1:
The patent divides the timing control function into multiple independent timing control circuits (first timing control circuit and second timing control circuit). Each circuit handles a portion of the display data (e.g., left half and right half of the screen), allowing the system to achieve high resolution (8K4K) without requiring a single complex high-resolution timing control circuit. This segmentation reduces the complexity and development cost of individual timing control circuits while maintaining overall high display resolution.
2Measurement precision
If two 4K2K timing control circuits are used with data expansion function, then 8K4K display is achieved, but timing control circuit specifications and components are limited
Solution Approach 1:
The patent introduces a dynamic data expansion mechanism where the timing control circuits can adaptively process and expand data between different resolutions. The first and second timing control circuits receive display data, perform data expansion to convert 4K2K signals into 8K4K signals, and dynamically allocate the expanded data to different scanning line groups. This dynamic capability allows the system to achieve high-resolution display without being constrained by fixed timing control circuit specifications.
3Ease of manufacture
If multiple timing control circuits are used to divide screen data, then timing component specifications can be reduced, but system complexity increases
Solution Approach 1:
The patent designs the timing control circuits and signal transmission circuit to perform multiple functions. The timing control circuits not only generate scanning signals but also perform data expansion and data allocation functions. The signal transmission circuit simultaneously manages data routing between timing control circuits and display panels, as well as coordinating the operation of multiple scanning line groups. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity despite using multiple timing control circuits.
