Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels with laser sensing structures face challenges in balancing increasing read time and controlling costs, as the number of read lines needed to enhance accuracy leads to higher costs and reduced signal reading accuracy with larger panel sizes.
Innovation Solution
The display panel incorporates alternately arranged scan and read lines, with sensing modules positioned at intersections, reducing the number of sensing modules required and allowing for increased read time without the need for additional read lines and circuits, thereby saving costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the number of read lines is increased to increase read time of each sensing module, then the read time is improved, but the manufacturing cost increases
Solution Approach 1:
The patent transitions from a conventional row-column sensing module arrangement to a triangular distribution arrangement. This dimensional change in spatial organization allows sensing modules to be positioned at vertices of triangles formed by scan lines and read lines, effectively increasing read time without requiring additional read lines, thus resolving the contradiction between read time improvement and cost control.
2Area of stationary object
If the panel size is increased, then the display area is improved, but the signal reading accuracy deteriorates
Solution Approach 1:
The patent implements local optimization by positioning sensing modules at specific triangular vertex locations rather than uniform distribution. This localized strategic placement ensures that each sensing module operates within an optimal detection range, maintaining signal reading accuracy across the entire large panel area by ensuring at least one sensing module is always within effective detection distance of the light spot.
