Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing devices with dual or foldable displays face temperature-induced variations in color and intensity, leading to perceived differences between display panels, which affect user experience and device performance.
Innovation Solution
The computing device determines temperature maps for each display panel based on hinge angle, temperature data, and other factors, and performs remedial actions such as adjusting power consumption, fan speed, and screen resolution to reduce temperature differences and maintain consistent color and intensity across displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display panel operates at high temperature, then the brightness and color intensity increase, but the color balance deteriorates and perceived differences between displays increase
Solution Approach 1:
The system dynamically adjusts display parameters (brightness, color temperature, gamma correction) based on detected temperature conditions to maintain consistent color appearance across displays operating at different temperatures
Solution Approach 2:
Temperature sensors provide feedback about the thermal state of each display panel, enabling the system to automatically compensate for temperature-induced color variations through real-time parameter adjustment
2Manufacturing precision
If cooling components are added to reduce temperature differences, then color consistency improves, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical cooling systems with software-based thermal compensation algorithms that adjust display parameters according to temperature sensor readings, achieving color consistency without additional cooling hardware
Solution Approach 2:
Each display panel incorporates temperature sensors and compensation algorithms that automatically adjust its own display characteristics based on its thermal state, eliminating the need for centralized cooling control
3Illumination intensity
If power consumption is increased to maintain display performance, then brightness and color intensity are maintained, but heat generation increases exacerbating temperature differences
Solution Approach 1:
The system adjusts display parameters such as gamma correction and color temperature to maintain perceived brightness and color quality at lower power consumption levels, reducing heat generation while preserving visual performance
Solution Approach 2:
The display system dynamically adjusts its power consumption and performance characteristics based on real-time temperature conditions, optimizing the balance between visual quality and heat generation

AI summary
In some examples, a computing device includes a first display in a first housing and a second display in a second housing. The computing device may determine an angle between the first display device and the second display device, determine a first temperature map of the first housing based on the angle and first temperature data received from a first set of temperature sensors in the first housing, and determine a second temperature map of the second housing based on the angle and second temperature data received from a second set of temperature sensors in the second housing. The computing device may determine a temperature difference between the first display device and the second display device, determine an action, and perform the action to reduce the temperature, color, and/or color intensity difference between the first display device and the second display device.
