Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display device is increased to support 8K broadcasting, then the image quality is improved, but the number of wirings and power consumption are increased
Solution Approach 1:
The patent combines multiple signal processing functions (shifting, sampling, holding, buffering) into an integrated semiconductor device that processes image data internally. This merging of functions reduces the need for separate wirings to external components, thereby reducing wiring complexity while maintaining 8K resolution capability.
Solution Approach 2:
The semiconductor device performs multiple functions including signal shifting, sampling, holding, and buffering within a single integrated circuit. This multi-functionality eliminates the need for separate discrete components and their associated wirings, reducing overall device complexity while supporting high-resolution image processing.
2Measurement precision
If the resolution of the display device is increased to support 8K broadcasting, then the image quality is improved, but the power consumption is increased
Solution Approach 1:
By integrating multiple signal processing functions into a single semiconductor device, the patent reduces the total power consumption associated with multiple separate components. The combined circuitry can be optimized for lower power operation while handling the high data rates required for 8K resolution.
Solution Approach 2:
The patent replaces traditional mechanical or discrete electronic signal processing systems with an integrated semiconductor-based system. This substitution enables more efficient power management and lower overall power consumption while maintaining the capability to process high-resolution image data.

If more wirings are used to transmit image data, then the data transmission capacity is improved, but the device complexity and cost are increased
Solution Approach 1:
The patent processes image data in the spatial domain within the semiconductor device, transforming the data dimensionally before output. This allows efficient data transmission with reduced wiring requirements by performing processing operations internally rather than requiring extensive wiring for external processing.
Solution Approach 2:
The integration of shifting, sampling, holding, and buffering functions into a single device consolidates the wiring requirements. The combined circuitry achieves the necessary data transmission capacity for high-resolution images without requiring a proportional increase in wiring complexity.
