Engineering Contradiction Analysis
1Measurement precision
If up-conversion is performed to convert low-resolution image to high-resolution image, then display resolution is improved, but circuit scale and power consumption increase enormously
Solution Approach 1:
The patent segments the image processing function by dividing the display system into a processing unit that handles only low-resolution image processing and pixel circuits that perform local correction operations. This segmentation allows high-resolution display without requiring the entire system to process high-resolution data, thereby reducing circuit scale while maintaining display resolution.
Solution Approach 2:
The patent introduces a temporal dimension by storing correction data in memory circuits within pixels. Instead of performing complex real-time up-conversion, the system uses pre-calculated correction data that is applied to low-resolution images, transforming the problem from a spatial processing challenge to a temporal solution where correction is applied after the fact.
2Measurement precision
If up-conversion is performed to convert low-resolution image to high-resolution image, then display resolution is improved, but power consumption increases enormously
Solution Approach 1:
The patent segments the computational load by performing only low-resolution processing in the power-constrained display circuitry while using a separate processing unit for heavy computation. This segmentation enables high-resolution display output without requiring the display circuit itself to consume enormous power for full up-conversion processing.
Solution Approach 2:
The patent applies preliminary action by pre-calculating correction data that compensates for the limitations of low-resolution processing. This correction data is stored in memory circuits and applied to the displayed image, allowing the system to achieve high-resolution display quality without performing power-intensive real-time up-conversion in the display circuit.
3Measurement precision
If the number of pixels is increased to achieve high resolution, then display resolution is improved, but display unevenness due to transistor characteristic variation becomes noticeable
Solution Approach 1:
The patent applies local quality by implementing pixel circuits with memory circuits that store individual correction data for each pixel or pixel group. This allows local compensation for transistor characteristic variations in different regions of the display, maintaining display uniformity across the entire high-resolution panel despite manufacturing variations in individual transistors.
Solution Approach 2:
The patent uses parameter changes by adjusting the correction data stored in pixel memory circuits to compensate for transistor characteristic variations. By changing the electrical parameters (voltage levels, timing) of individual pixels based on stored correction data, the system maintains uniform display quality across all pixels despite manufacturing variations.
4Measurement precision
If complex image processing is performed in real-time, then display resolution is improved, but display delay increases
Solution Approach 1:
The patent segments processing tasks by separating real-time low-resolution processing from non-real-time correction operations. The processing unit handles time-sensitive low-resolution processing while correction data generation and application are performed separately, enabling real-time display updates without the delay of full high-resolution processing.
Solution Approach 2:
The patent applies preliminary action by pre-generating correction data that can be applied to low-resolution images in real-time. This allows the system to perform complex image processing in advance and store the results, enabling real-time display of high-resolution quality images without the processing delay that would occur if full up-conversion were performed at display time.
