Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection systems require high power illumination sources and are prone to pixel failures due to data line concentration, which can lead to reduced reliability and increased susceptibility to physical stress.
Innovation Solution
A projection system comprising a substrate with pixels that include sensors to receive information orthogonally and circuitry to process and emit signals, eliminating the need for data lines and allowing for robustness against physical stress, and a projector that encodes and modulates light to amplify projections.

Engineering Contradiction Analysis
1Ease of operation
If data lines are concentrated to route display information in the plane of the screen, then image display functionality is achieved, but pixel failure risk increases due to concentration of data lines
Solution Approach 1:
The patent transitions from planar data routing to three-dimensional signal transmission by receiving signals from a projector in a direction substantially orthogonal to the plane of the pixels. Each pixel independently receives modulated light signals containing image information, eliminating the need for concentrated data lines and reducing failure risk while maintaining image display functionality.
2Power
If high power illumination sources are used in the projector, then image projection capability is achieved, but energy consumption and susceptibility to physical stress increase
Solution Approach 1:
The patent replaces the conventional high-power illumination system with a low-power optical projection system. Instead of using high-power lights that generate heat and physical stress, the system uses a projector to modulate light at a lower power level, which is then received and amplified by each pixel independently, achieving the same projection capability with reduced physical stress.
3Device complexity
If data lines are concentrated in the plane of the screen, then routing is simplified, but robustness against physical stress decreases
Solution Approach 1:
The patent eliminates planar data line routing by receiving signals orthogonally from the projector. This three-dimensional approach distributes the signal reception across multiple pixels independently, removing the need for concentrated data lines and thereby increasing robustness against physical stress while maintaining manageable system complexity through direct optical signal reception.
