Display Panel Processing Circuit with Region-Based Refresh Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High display quality requirements lead to increased refresh rates in display panels, resulting in significant power consumption and resource occupation in display devices.
Innovation Solution
A processing circuit for display panels that divides the display into regions, using a sight line acquisition circuit to determine focused areas and adjust refresh rates accordingly, with higher refresh rates for focused regions and lower rates for non-focused regions, employing a frame interpolation algorithm to maintain image quality while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the refresh rate of the display panel is increased to improve display quality, then the display quality is improved, but the power consumption increases significantly
Solution Approach 1:
The display panel is divided into multiple display regions, each controlled by independent display control circuits. This segmentation allows different refresh rates to be applied to different regions, enabling high refresh rates only in focused regions while using lower refresh rates in non-focused regions, thus reducing overall power consumption while maintaining display quality where needed
Solution Approach 2:
The refresh rate of each display region is dynamically adjusted based on real-time sight line detection. When a region is detected as the focused region, its refresh rate is increased to ensure high display quality. When not focused, the refresh rate is reduced to save power. This dynamic adjustment resolves the contradiction between maintaining high display quality and reducing power consumption
2Manufacturing precision
If the refresh rate of the display panel is increased to improve display quality, then the display quality is improved, but the processing resources occupied increase
Solution Approach 1:
The display panel is segmented into multiple regions with independent control circuits. This allows the processing load to be distributed across multiple independent circuits rather than requiring one high-performance circuit to handle the entire panel at high refresh rates, reducing the peak processing resource requirements while maintaining display quality in focused regions
Solution Approach 2:
High refresh rates are applied only to the partial region that is currently in focus, rather than applying high refresh rates to the entire display panel. This partial action approach maintains high display quality where needed while significantly reducing the overall processing resources required
