Display Panel Power Saving Effect Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying the power saving effect while exercising power saving control is challenging due to variations in brightness or panel shutdown, making it difficult to accurately present the power saving effect, especially when the panel is made darker or turned off.
Innovation Solution
A display method and apparatus that combine face detection using an imaging unit and moving body detection by a sensor to analyze the viewing state, allowing for effective power saving control and displaying the power saving effect on a portion of the display panel, while maintaining accurate representation of the power saving effect by calculating and displaying the actual power consumption reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power saving control is exercised by making the panel darker or turning it off based on face detection or moving body detection, then power consumption is reduced, but it becomes difficult to display the power saving effect on the display panel
Solution Approach 1:
The display panel is divided into a first display region and a second display region. The first display region displays the original image content, while the second display region specifically displays power saving effect information. This segmentation allows the power saving effect to be displayed without requiring the entire panel to remain at full brightness, thus maintaining power savings while providing visibility of the effect.
Solution Approach 2:
A third display device is introduced as an intermediary to display the power saving effect information. This third device receives power consumption data from the display apparatus and presents it in a form that is visible to users without requiring the main display panel to maintain high brightness levels, thus solving the contradiction between power saving and effect visibility.
2Productivity
If the power saving effect is displayed in the display panel during power saving control, then user appeal is enhanced, but the actual power saving effect is misrepresented due to brightness variations or panel shutdown
Solution Approach 1:
A third display device serves as an intermediary that accurately displays power saving effect information without being subject to the brightness variations or shutdown states of the main display panel. This separate display device provides an accurate representation of power consumption data and savings, ensuring measurement precision while still enhancing user appeal through clear information presentation.
Solution Approach 2:
The power saving effect information is copied and displayed on a separate third display device rather than being overlaid on the main display panel. This copying approach ensures that the power saving effect information is presented accurately without being affected by the display panel's brightness changes or shutdown states, thus maintaining measurement precision.
3Use of energy by stationary object
If the display panel brightness is reduced or panel is turned off for power saving, then energy consumption is reduced, but the ability to monitor and display power saving effect is compromised
Solution Approach 1:
The display system is segmented into multiple functional regions and devices. The main display panel is segmented into first and second display regions, with the second region dedicated to power saving effect information. Additionally, a separate third display device is used to ensure that power saving effect information is always visible and not lost, even when the main panel reduces brightness or shuts off for energy conservation.
Solution Approach 2:
The third display device acts as an intermediary that receives and displays power saving effect information independently of the main display panel's power saving operations. This intermediary ensures that information about power savings is preserved and made visible to users, preventing information loss while the main panel performs energy conservation functions.

AI summary
To provide a display method capable of displaying the original power saving effect if a monitoring display of the power saving effect is not made when the monitoring display of the power saving effect is made. Provided is a display method including capturing an image in front of an image display surface included in a display apparatus that displays the image and detecting presence of a moving body positioned in front of the image display surface, deciding a power saving amount of the display apparatus including the power saving amount of the image display surface by using an analysis result of the presence or absence of a human face and a detection result of the moving body in the captured image, and deriving and displaying the actual power saving amount when no display is made on the image display surface on the image display surface when information about the power saving amount is displayed on the image display surface. Accordingly, when a monitoring display of a power saving effect is made, an original power saving effect if no monitoring display of the power saving effect is made can be displayed.
