Projection Layer Pixel Adaptation for Power and Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic displays lack the ability to efficiently switch between dynamic and semi-static modes, resulting in high power consumption and limited flexibility in displaying content, as they often require separate configurations for emissive and non-emissive operations.
Innovation Solution
A system with a projection layer comprising electronically controllable pixels that can vary their appearance in coordination with projected images, allowing for dynamic and semi-static modes of operation without the need for separate configurations, by using a combination of display technologies such as LCD, OLED, and electrochromic displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate configurations are used for emissive and non-emissive operations, then display functionality is comprehensive, but device complexity increases
Solution Approach 1:
The patent combines emissive and non-emissive display configurations into a single integrated system. The projection layer with electronically controllable pixels merges the functionality of separate emissive (OLED) and non-emissive (LCD) displays, allowing both modes to operate within one unified device structure rather than requiring separate physical configurations.
Solution Approach 2:
The projection layer serves multiple functions simultaneously - it can operate in emissive mode to generate light for dark environments, switch to non-emissive mode for bright environments with ambient light, and dynamically adjust between these states. This multi-functional design eliminates the need for separate dedicated devices for different viewing conditions.
2Adaptability or versatility
If dynamic mode is used for continuous content updates, then content flexibility is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between emissive and non-emissive modes based on environmental conditions and content requirements. The projection layer can adapt its operational state in real-time, transitioning from power-intensive dynamic emission mode to energy-efficient reflective mode when ambient light is sufficient, thereby optimizing power consumption while maintaining content flexibility.
Solution Approach 2:
The patent changes the operational parameters of the display by switching between different modes (emissive vs. non-emissive). This parameter change allows the system to adjust power consumption levels according to viewing conditions - using high-power emissive mode only when necessary for dark environments or dynamic content, and low-power reflective mode for static content in bright environments.
3Use of energy by moving object
If non-emissive mode is used to reduce power consumption, then energy efficiency is improved, but display capability in dark environments deteriorates
Solution Approach 1:
The display system dynamically adapts its mode based on ambient light conditions. In dark environments, it automatically transitions from non-emissive reflective mode to emissive mode, where the OLED layer generates its own light to ensure adequate brightness. This dynamic adaptation resolves the contradiction by only using power-intensive emissive mode when actually needed for dark environment viewing.
Solution Approach 2:
The projection layer acts as an intermediary between the OLED and LCD layers, coordinating their operation based on environmental conditions. It manages the transition between modes and ensures that the appropriate layer is activated - using the OLED's self-emissive capability in dark conditions and the LCD's reflective capability in bright conditions - thereby optimizing both power consumption and display performance.
