Optical Deflector Temporal Scanning for Display Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display electronic devices are limited in achieving high-resolution images due to the constraints of pixel unit dimensions and existing processing technologies, which restrict further improvement in display panel resolution.
Innovation Solution
Incorporating an optical deflector that shifts the irradiation angle of light groups emitted by the display panel within the visual persistence duration of the human eye, forming multiple light groups that enhance image resolution without altering the pixel unit dimensions, thereby overcoming the 'screen-door effect' and improving image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pixel unit dimensions are reduced to improve display panel resolution, then the resolution cannot be further improved due to fabrication precision constraints
Solution Approach 1:
The patent introduces a temporal dimension to the display system by utilizing visual persistence. Instead of improving resolution through spatial dimension (smaller pixels), the system uses time-based light group manipulation within the visual persistence duration to achieve higher effective resolution. The optical deflector creates multiple light groups from a single pixel unit over time, effectively adding a temporal layer to the spatial display architecture.
Solution Approach 2:
The patent introduces an optical deflector as an intermediary component between the display panel and the observer's eye. This intermediary manipulates light paths to create multiple light groups from single pixel units, effectively mediating the resolution enhancement without requiring smaller pixels. The optical deflector acts as a bridge that transforms limited pixel output into enhanced visual resolution through temporal light manipulation.
2Measurement precision
If multiple light groups are formed within visual persistence duration to enhance resolution, then the device complexity increases
Solution Approach 1:
The optical deflector serves multiple functions: it directs light groups to different regions, controls the timing of light emission, and creates the temporal separation necessary for resolution enhancement. By making the optical deflector a multi-functional component that handles both spatial and temporal light manipulation, the patent reduces the need for additional separate components, thereby managing device complexity while achieving enhanced resolution.

AI summary
An electronic device includes a display panel and an optical deflector. The display panel irradiates an original light group corresponding to an original image displayed by the display panel and having a first resolution. The optical deflector receives the original light group and emits at least two output light groups having different transmission directions within a visual persistence duration. The at least two output light groups form an output image having a second resolution greater than the first resolution.
