Display Region Filtering Based on Pixel Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-saving modes in electronic displays, such as reducing screen brightness or disabling features, can negatively impact performance and visibility, and do not effectively conserve power by deactivating only non-critical pixels.
Innovation Solution
Assigning pixel priority values to determine the relative importance of each pixel and deactivating those that do not meet a defined threshold, allowing critical pixels to remain active while non-critical pixels are turned off, thereby reducing power consumption without affecting performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If existing power-saving modes reduce screen brightness or disable features, then power consumption is reduced, but visibility and performance are negatively impacted
Solution Approach 1:
The display is segmented into multiple regions with different priority levels (first display region with first pixels and second display region with second pixels). Different power-saving strategies are applied to different segments, allowing critical regions to maintain full performance while non-critical regions consume less power.
Solution Approach 2:
Different quality levels are applied to different parts of the display. The first display region maintains high quality with all pixels active, while the second display region applies lower quality with selectively deactivated pixels, optimizing the balance between power consumption and visual quality in different areas.
2Reliability
If all pixels are kept active to maintain visibility, then performance is preserved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts pixel activation based on priority values and thresholds. Pixels are selectively deactivated or activated depending on their priority value relative to a dynamic threshold, allowing the display to adapt power consumption to the actual visual requirements of different regions.
Solution Approach 2:
The system changes the operational parameters of pixels by assigning priority values and adjusting activation thresholds. By modifying these parameters, the system can control which pixels remain active and which are deactivated, optimizing the balance between visibility and power consumption.
3Use of energy by moving object
If non-critical pixels are deactivated to save power, then power consumption is reduced, but display complexity increases due to priority assignment and threshold comparison
Solution Approach 1:
Priority values for each pixel are predetermined and assigned before the power-saving operation begins. This preliminary action simplifies the subsequent threshold comparison process, as the system only needs to compare each pixel's pre-assigned priority value against the threshold rather than performing complex analysis in real-time.

AI summary
Aspects of the present disclosure relate to display region filtering. A pixel priority value for each of a plurality of pixels on a display region are assigned in response to identifying portions of the display region for prioritization, wherein the pixel priority values indicate a relative importance of each of the pixels, respectively, for viewing based on a magnitude of the pixel priority values. The pixel priority value of each pixel is compared to a first pixel priority threshold to identify pixels of the plurality of pixels having pixel priority values which do not satisfy the first pixel priority threshold. The pixels of the plurality of pixels having pixel priority values which do not satisfy the first pixel priority threshold are deactivated, wherein a subset of pixels satisfies the first pixel priority threshold and remain active.
