Integrated Display Colorimeter Positioning Against Ambient Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays in color-critical applications face challenges with inaccurate color calibration due to ambient light interference and fixed positioning of colorimeters, leading to reduced display accuracy across multi-user environments.
Innovation Solution
An integrated colorimeter system within a display that deploys a colorimeter via a hinged door mechanism, allowing movement along two axes to position the sensor closer to the screen and block ambient light, enhancing measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a colorimeter is integrated into the display, then color calibration accuracy is improved, but ambient light interference worsens measurement precision
Solution Approach 1:
The colorimeter is extracted from the main display body and placed on a deployable tray that can be extended outward. This physical separation removes the colorimeter from the ambient light environment of the display workspace, allowing accurate measurements when deployed.
Solution Approach 2:
The system performs preliminary deployment of the colorimeter tray before measurement begins. The tray extends automatically to position the colorimeter in its measurement location, and the measurement process is initiated only after the tray is fully deployed, ensuring the colorimeter is already protected from ambient light interference.
2Measurement precision
If the colorimeter is positioned closer to the screen, then measurement accuracy is improved, but the risk of light-blocking material contact with screen increases
Solution Approach 1:
A flexible light-blocking material is used to surround the colorimeter sensor. This material can conform to the screen surface when the colorimeter is positioned close, creating a light seal without rigid contact that could damage the screen or interfere with measurements.
Solution Approach 2:
The colorimeter's positioning is dynamic rather than fixed. The tray can extend to various positions, and the light-blocking material can flex and adapt its shape based on the distance to the screen, allowing optimal measurement positioning while maintaining screen safety.
3Device complexity
If the colorimeter is fixed in position, then device complexity is reduced, but adaptability to different measurement conditions worsens
Solution Approach 1:
The colorimeter positioning system is made dynamic through the deployable tray mechanism. The tray can extend and retract automatically, allowing the colorimeter to transition between stored and measurement positions without manual intervention, maintaining simplicity while adding adaptability.
Solution Approach 2:
The deployable tray mechanism serves multiple functions: it positions the colorimeter for measurement, protects the colorimeter when retracted, and provides a platform for the light-blocking material. This multi-functionality reduces the need for separate mechanisms while increasing adaptability.

AI summary
An Information Handling System (IHS) display includes an integrated colorimeter that is stored within a front-facing bezel that borders one side of the display screen. The front-facing bezel includes hinged door that conceals a compartment housing a tray. The tray includes a colorimeter and is deployed from the front-facing bezel via the hinged door. With the tray deployed, the colorimeter is raised from the tray and positioned for measuring light emitted by the screen. The deployment of the tray from the front-facing bezel is along an axis perpendicular to the screen and the raising of the colorimeter from the deployed tray is along an axis parallel to the screen. The raised colorimeter may be positioned closer to the screen though movement of the tray along the axis perpendicular to the screen, thus reducing ambient light that reaches a colorimeter sensor of the colorimeter.
