Selective Pixel Illumination for Context-Aware Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle displays consume excessive energy due to all pixels being lit evenly, leading to high energy consumption and difficulty in achieving contrast, and are difficult to disassemble for recycling, with limited usability for rear seat passengers and external viewing.
Innovation Solution
A system that analyzes content to determine redundant and relevant portions, selectively activating only necessary pixels for optimized energy consumption, and adjusts display alignment and orientation based on occupant position and vehicle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If all pixels are lit evenly throughout the display, then the display provides uniform illumination, but energy consumption increases and contrast ratio deteriorates
Solution Approach 1:
The patent applies local quality by enabling different illumination levels for different regions of the display. The system selectively activates only the pixels necessary to display the current content, allowing illuminated regions where content is present and dark regions where content is absent, thereby reducing overall energy consumption while maintaining appropriate brightness where needed
Solution Approach 2:
The patent segments the display into individually controllable pixels that can be selectively activated. By analyzing the content to be displayed and identifying which specific pixels are necessary, the system divides the display operation into discrete pixel-level control, enabling precise energy management at the pixel level rather than uniform control of the entire display
2Illumination intensity
If all pixels are lit evenly throughout the display, then the display provides complete coverage, but contrast ratio deteriorates
Solution Approach 1:
The patent improves contrast ratio by applying local quality principles where pixels displaying dark or black content remain inactive or at minimal illumination levels, while pixels displaying light content are fully activated. This creates genuine black levels and high contrast without requiring uniform illumination across the entire display panel
3Productivity
If large displays are used to provide information to driver and front seat passenger, then information display capability improves, but energy consumption increases and driver distraction increases
Solution Approach 1:
The patent reduces energy consumption of large displays by applying local quality control - activating only the specific pixel regions necessary to display current information while leaving other regions dark. This maintains the large display's information capacity while dramatically reducing power usage by eliminating illumination of unused areas
4Ease of operation
If front row display placement is used, then driver and front seat passenger can view content, but rear seat passenger usability is limited
Solution Approach 1:
The patent applies dynamics by making the display content and active pixel regions adaptable to different viewing situations. The system can dynamically adjust which pixels are activated based on detected passenger positions, enabling the same physical display to serve different audiences appropriately - showing driver-relevant information to the driver and entertainment content to rear passengers when present

AI summary
A system is described. The system comprises: a display; a display control module; and a processor storing instructions that, when executed, causes the processor to: analyze one or more contents and determine one or more contexts of the one or more contents; determine one or more redundant portions and one or more relevant portions of the one or more contents based on the contexts of the one or more contents; identify one or more first pixels that correspond to the one or more redundant portions; identify one or more second pixels that correspond to the one or more relevant portions; and communicate a command to the display control module to control the one or more first pixels and the one or more second pixels to display the one or more contents with optimized energy consumption in response to the contexts.
