Image Display Device Partial Layer Data Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display devices face inefficiencies in power consumption and operating efficiency due to the need to read and process both valid and invalid data layers, leading to increased bandwidth usage and power consumption, especially at higher image display frequencies.
Innovation Solution
The solution involves an image display device and method that reads partial data from layers, specifically identifying and separating valid data within the second layer data, and blending it with first layer data to generate and display blended data, reducing the need to read and process invalid data, thereby optimizing bandwidth and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data in the second layer is read and processed, then complete image information is displayed, but bandwidth consumption and power usage increase
Solution Approach 1:
The patent extracts only the valid data portions from the second layer by using a display buffer to store validity information and reading only those specific portions, excluding invalid data. This extraction principle directly reduces bandwidth consumption and power usage while maintaining complete image display by ensuring all valid pixels are processed.
2Reliability
If all data in the second layer is read and processed, then complete image information is displayed, but processing time increases
Solution Approach 1:
The patent extracts only the valid data portions from the second layer by using a display buffer to store validity information and reading only those specific portions, excluding invalid data. This extraction principle directly reduces processing time while maintaining complete image display by ensuring all valid pixels are processed.
3Use of energy by moving object
If partial data from the second layer is read, then power consumption is reduced, but image display completeness may be compromised
Solution Approach 1:
The patent performs preliminary action by pre-storing validity information for each data block in the display buffer before the actual display process. This allows the system to quickly identify and read only valid data portions during display, ensuring complete image rendering while minimizing power consumption. The preliminary organization of validity data prevents any loss of image completeness.
