Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses experience image quality degradation over time due to factors such as reduced light intensity, color changes, and performance deterioration from prolonged use.
Innovation Solution
A display apparatus and system that includes a communicator to transmit operation and environment information to a service apparatus, which provides image parameters for correcting image quality degradation based on total operating time, temperature, and geographic location, using a controller to process and display images accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display apparatus operates for a long time, then productivity increases, but image quality deteriorates due to light intensity reduction and color changes
Solution Approach 1:
The patent applies parameter changes by adjusting display parameters (brightness, contrast, color temperature) based on the accumulated operating time. The controller modifies these parameters dynamically to compensate for the degradation caused by prolonged operation, thereby maintaining image quality while allowing continuous productivity.
Solution Approach 2:
The system implements feedback by continuously monitoring the operating time and using this information to adjust display parameters. The controller receives feedback about the accumulated operation duration and automatically compensates for image quality degradation, creating a closed-loop system that maintains reliability over time.
2Illumination intensity
If the display apparatus operates at high brightness, then illumination intensity improves, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the brightness level adjustable and adaptive rather than fixed. The controller dynamically modifies the brightness parameter based on operating time and environmental conditions, allowing the system to optimize between illumination intensity and energy consumption depending on the specific operating context.
3Measurement precision
If the display apparatus operates at high contrast, then image sharpness improves, but color accuracy deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting multiple display parameters (contrast, color temperature, brightness) in a coordinated manner based on operating time. Rather than fixing contrast at a high level, the controller dynamically modifies these parameters to maintain both sharpness and color accuracy, compensating for degradation that occurs during prolonged operation.

AI summary
A display apparatus capable of correcting an image quality change caused by long-term use is provided. The display apparatus includes: a display panel; a communicator configured to communicate with a service apparatus; and a controller configured to control the communicator to transmit operation information including a total operating time of the display apparatus and an operating temperature of the display apparatus, to the service apparatus; receive an image parameter from the service apparatus through the communicator, and based on the received image parameter data; process image data; and transmit the processed image to the display panel. The image parameter may include at least one of a brightness level, a contrast, a sharpness level, and a color density of the display panel.
