Solution Overview

Problem

Current display systems face a high processing load when presenting different images to multiple directions, leading to inefficiencies in image rendering for multiple viewers.

Innovation Solution

A multi-directional display system with N pixel sets and a processor that determines the direction of each viewer, allowing images to be displayed to less than N directions, reducing unnecessary rendering and processing load by using a lenticular sheet and image processing device to direct images accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different images are rendered for each of N directions to serve multiple viewers, then the display system can provide personalized images to viewers in different directions, but the image processing load becomes extremely large

Engineering Contradiction:
ImproveAbility to display different images to multiple directionsVSAvoidImage processing load
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies partial action by determining the actual number of directions M where viewers are present and rendering images only for those M directions instead of all N directions. This reduces the processing load from rendering N parallel images to rendering only M images where M ≤ N, while still providing personalized viewing experiences for all present viewers.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts the number of rendered images based on the real-time detection of viewer positions. The processor determines the direction of each person and dynamically selects which pixel sets should display images, changing the rendering workload from a static N-direction approach to a dynamic M-direction approach where M varies with the number and positions of present viewers.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If N pixel sets are used to display images in N different directions, then the display system achieves multi-directional viewing capability, but the device complexity increases

Engineering Contradiction:
ImproveMulti-directional display capabilityVSAvoidNumber of pixel sets and processing requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the pixel sets universal by enabling each pixel set to potentially display images in multiple directions depending on viewer presence. Instead of dedicating each pixel set to a single fixed direction, the system can dynamically assign different pixel sets to different directions based on where viewers are located, reducing the need for N dedicated pixel sets when fewer than N directions are actually needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system extracts and activates only the necessary subset of pixel sets required for the current viewing scenario. By determining which directions have viewers present, the processor extracts only the relevant pixel sets for image rendering, leaving other pixel sets inactive or repurposed, thereby reducing the effective device complexity for any given moment.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A display system includes N (N is a natural number) pixel sets, and a processor. The N pixel sets are capable of displaying different images in N directions. The processor is configured to determine a direction of a person, the person being a person able to view each of the N pixel sets, the direction being a direction in which the person is located. The processor is also configured to cause an image to be displayed by a pixel set, the image being an image directed to each of less than N directions including at least the determined direction, the pixel set being at least one of the N pixel sets corresponding to each of the less than N directions.
