Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic device displays experience reduced optical performance and user discomfort due to temperature-related changes in color presentation, as they generate heat, leading to potential damage and self-regulation that compromises image quality.
Innovation Solution
A method that identifies visual content and applies a color profile with temperature-dependent tristimulus values to adjust color output in real-time, compensating for thermal effects by modifying tristimulus values and adjusting gain or gamma settings to maintain accurate color representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display operates at high power levels to maintain optical performance, then image quality is improved, but heat generation increases causing color distortion and potential damage
Solution Approach 1:
The system applies color correction profiles in advance based on predicted temperature changes. The processor identifies upcoming thermal conditions and pre-adjusts color parameters before significant distortion occurs, counteracting the harmful thermal effect before it impacts image quality.
Solution Approach 2:
The system dynamically changes color parameters (tristimulus values, gamma, gain) based on temperature conditions. By adjusting these parameters in response to temperature variations, the system compensates for thermal-induced color distortion while maintaining optimal optical performance across different operating conditions.
2Temperature
If the display self-regulates drive power to mitigate heat effects, then temperature control is improved, but optical performance and user experience deteriorate
Solution Approach 1:
The system introduces color correction profiles as an intermediary mechanism between the display hardware and the visual output. These profiles act as a mediator that compensates for thermal effects without requiring reduction of drive power, thus maintaining optical performance while controlling temperature impacts.
Solution Approach 2:
Instead of reducing drive power to control temperature effects, the system changes color parameters (tristimulus values, gamma correction, gain) to compensate for thermal distortion. This allows the display to operate at optimal power levels while maintaining image quality through parameter adjustment.
3Productivity
If the display operates continuously without power regulation, then productivity is maintained, but heat accumulation causes color distortion and reduced reliability
Solution Approach 1:
The system continuously monitors display temperature and provides feedback to the processor, which then adjusts color parameters in real-time. This closed-loop feedback mechanism allows continuous operation while maintaining reliability through dynamic color correction based on actual thermal conditions.
Solution Approach 2:
The system maintains continuous operation by dynamically changing color parameters in response to temperature accumulation. As the display operates continuously, the processor adjusts tristimulus values, gamma, and gain parameters to compensate for heat-induced distortion, preserving both productivity and reliability.

AI summary
A method, a system, and a computer program product for managing image quality of an electronic display. The method includes identifying a visual content encoded in a first color space that is to be presented on an electronic display. The method further includes identifying, for the electronic display, a color profile that specifies color tristimulus values for the electronic display that are expressed as a function of temperature. The method further includes determining a current temperature of the electronic display and applying the color profile to the visual content to create a modified visual content for presentation on the electronic display. The method further includes rendering the modified visual content by the electronic display and adjusting, during rendering of the modified visual content, the color tristimulus values of the modified visual content in real-time based on the current temperature.
