Engineering Contradiction Analysis
1Reliability
If conventional lenticular arrays with DDICs are used to achieve stereoscopic effects, then depth perception is enabled, but pixel utilization efficiency deteriorates and resolution is reduced
Solution Approach 1:
The patent applies dynamic pixel selection where the display driver circuit dynamically determines which pixels are visible to each eye based on real-time viewing position detection. This dynamic approach replaces the static pixel assignment in conventional lenticular arrays, allowing the system to adaptively optimize pixel utilization while maintaining stereoscopic effects across multiple viewing positions.
Solution Approach 2:
The system changes the parameter of pixel activation status from static to dynamic by using viewing position information. The display driver circuit modifies which pixels are activated based on detected viewing positions, thereby changing the effective pixel utilization parameter to maximize the number of usable pixels while preserving depth perception.
2Manufacturing precision
If all sub-pixels are driven to maintain full resolution, then image quality is preserved, but computational complexity and power consumption increase
Solution Approach 1:
The patent applies local quality by selectively activating only those pixels that are visible to each eye based on viewing position. Instead of uniformly driving all pixels, the display driver circuit applies different activation states to different local regions (pixels) depending on their visibility, thereby reducing overall power consumption while maintaining image quality in the visible regions.
Solution Approach 2:
The system performs partial action by activating only the necessary subset of pixels required for each viewing position rather than all pixels. This partial activation reduces computational complexity and power consumption while sufficient image quality is maintained for the visible pixels, avoiding the excessive energy expenditure of driving unnecessary pixels.
3Loss of information
If high-bandwidth transmission is used to deliver image data for all sub-pixels, then complete image information is transmitted, but GPU resource efficiency and power consumption deteriorate
Solution Approach 1:
The patent extracts only the necessary image data for visible pixels by using viewing position information to determine which pixels require data transmission. The display driver circuit extracts and processes only the relevant subset of pixel data needed for current viewing positions, eliminating the need to transmit and process data for all pixels, thereby improving GPU efficiency while maintaining complete image information for the visible regions.
4Device complexity
If static lenticular arrays are used to simplify processing, then device complexity is reduced, but adaptability to user position changes deteriorates
Solution Approach 1:
The patent introduces dynamics by implementing a viewing position detection mechanism that provides real-time feedback to the display driver circuit. This enables the system to adapt pixel selection and activation based on actual user position changes, significantly improving position adaptability compared to static lenticular arrays while maintaining manageable complexity through efficient detection and response mechanisms.

AI summary
Information indicative of a relative location of a first eye and a second eye of an individual one of user(s) with respect to a multiscopic optical element is obtained. A first image and a second image are generated or retrieved. For a given multiscopic cell and a given horizontal scanline, first photo-emitting cell(s) and second photo-emitting cell(s) are selected from amongst photo-emitting cells lying on the given horizontal scanline and on whose optical path the given multiscopic cell lies. Then, intensity values for the first photo-emitting cell(s) and the second photo-emitting cell(s) are retrieved. Information indicating the intensity values for the first photo-emitting cell(s) and the second photo-emitting cell(s), and metainformation indicating locations of such photo-emitting cells are included in an input signal being sent to a display driver. Drive signals are generated. Display is driven to present the first image and the second image.
