Display Color Alignment via Server-Side Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays face inaccuracies in color representation when connected to a computer system with different color settings, due to universal color tuning parameters that fail to account for manufacturing variations across identical display panels.
Innovation Solution
A method involving a server and processing unit that determines a color information file based on display-specific information, downloads, and enables it according to a preset mode, such as sRGB or DCI-P3, to align color settings between the display and computer system, ensuring accurate color calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If universal color tuning parameters are used for all display panels from the same manufacturer, then the ease of manufacture is improved, but the manufacturing precision deteriorates because it cannot calibrate differences generated during the manufacturing process
Solution Approach 1:
The patent creates a one-to-one correspondence between display panels and color information files by using unique identification codes. Each display panel receives its own dedicated color information file that contains customized color tuning parameters specific to that panel's manufacturing characteristics, rather than using universal parameters for all panels from the same manufacturer.
Solution Approach 2:
The patent changes the color tuning parameters from universal fixed values to customized values specific to each display panel. The server determines and provides unique color information files with tailored parameters for each display panel based on its identification code, allowing precise calibration of color characteristics for individual panels.
2Ease of operation
If preset color modes are used in conventional displays, then the ease of operation is improved, but the reliability deteriorates because the displayed color is not accurate when the computer system color setting differs from the display preset mode
Solution Approach 1:
The system establishes a feedback mechanism where the server receives identification information from the display, determines the appropriate color information file, and provides it back to the display. This closed-loop process ensures that each display receives accurate color calibration data corresponding to its specific characteristics and the computer system's color settings.
Solution Approach 2:
The patent performs preliminary color calibration by having the server determine and provide the appropriate color information file to the display before the display is used. This advance preparation ensures that color accuracy is established beforehand, eliminating the need for manual color setting adjustments by users.
3Device complexity
If universal color tuning parameters are used for all display panels, then the device complexity is reduced, but the measurement precision deteriorates because color differences generated during manufacturing cannot be calibrated
Solution Approach 1:
The patent introduces a server as an intermediary between display manufacturers and end users. The server stores and manages individual color information files for each display panel, receiving identification information from displays and providing the corresponding customized color calibration data. This intermediary system enables precise color calibration without requiring complex calibration equipment at the manufacturer or user end.

AI summary
A color aligning method of display for a computer system having a processing unit, a display and a server includes determining, by the server, a color information file of the display according to a related information of the display; downloading, by the processing unit, the color information file of the display from the server; and enabling, by the processing unit, the color information file according to a preset mode of the display.
