Engineering Contradiction Analysis
1Measurement precision
If a position sensitive liquid crystal display (PSLCD) device is used for position sensing, then position detection capability is achieved, but the device becomes complex, thick, and heavy due to additional control circuitries and structural requirements
Solution Approach 1:
The patent extracts the light reflection amplification function from complex control circuitries and implements it through a simple optical structure consisting of a light reflective layer and a light reflecting amplification structure. This removes unnecessary complex components while retaining position sensing capability through optical code detection.
Solution Approach 2:
Instead of using complex active sensing components, the patent inverts the approach by using a passive optical structure that amplifies light reflection. The light reflecting amplification structure with protrusions creates enhanced reflection without requiring active control circuitries, thereby simplifying the device while maintaining sensing functionality.
2Measurement precision
If a position sensitive liquid crystal display (PSLCD) device is used for position sensing, then position detection capability is achieved, but the device becomes thick and heavy due to additional structural requirements
Solution Approach 1:
The patent removes thick structural components and control circuitries from the display device, replacing them with a thin light reflecting amplification structure that consists of a reflective layer and protrusions on the substrate surface. This extraction reduces device thickness while preserving position detection through optical code amplification.
3Measurement precision
If a position sensitive liquid crystal display (PSLCD) device is used for position sensing, then position detection capability is achieved, but the device becomes heavy due to additional structural requirements
Solution Approach 1:
The patent extracts heavy control circuitries and complex structural components from the display device, replacing them with a lightweight light reflecting amplification structure comprising a reflective layer and surface protrusions. This reduction in material quantity and structural complexity directly decreases device weight while maintaining sensing capability.
4Measurement precision
If a light reflecting amplification structure with protrusions and reflective layer is implemented, then light reflection intensity is amplified for improved code detection, but manufacturing complexity increases
Solution Approach 1:
The patent merges the light reflection amplification function with the existing display substrate by integrating the protrusions directly onto the substrate surface and depositing the reflective layer over them. This combination eliminates the need for separate amplification components and simplifies the manufacturing process while achieving enhanced light reflection for code detection.
