Reset Conflict Arbiter for Phased-Reset Spatial Light Modulators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Phased-reset techniques in spatial light modulator (SLM) systems often result in reset conflicts, which limit the number of intensity levels attainable and degrade image quality due to overlapping reset signals in different groups of pixels.
Innovation Solution
A reset conflict arbiter is introduced to receive and resolve conflicts by shifting the execution time of selected reset instructions, ensuring that reset signals do not overlap, thereby improving the image quality by allowing more precise control over pixel intensity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If phased-reset techniques are used to address SLM pixels in distinct groups, then the addressing efficiency is improved, but reset conflicts occur that limit intensity levels and degrade image quality
Solution Approach 1:
The patent applies preliminary action by detecting potential reset conflicts before they occur and preemptively adjusting the timing of reset signals. The system identifies groups that would experience overlapping reset signals and shifts their timing in advance, preventing the conflict from degrading image quality while maintaining the efficiency benefits of phased-reset addressing.
2Productivity
If phased-reset techniques are used to address SLM pixels in distinct groups, then the addressing efficiency is improved, but the number of attainable intensity levels is limited
Solution Approach 1:
The system performs preliminary detection of reset signal overlaps and adjusts timing before conflicts limit intensity levels. By proactively scheduling non-conflicting reset operations, the system enables higher intensity resolution that would otherwise be unavailable due to timing conflicts in phased-reset modes.

AI summary
A system for, and method of resolving reset conflicts in a phased-reset SLM system and a projection visual display system incorporating the system or the method. In one embodiment, the system includes a reset conflict arbiter configured to receive reset instructions containing conflicts from a sequence generator and resolve the conflicts by shifting an execution time of a selected one of the reset instructions according to a conflict resolution method.
