Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in switching display modes without causing a sense of unnaturalness to the user, particularly when power consumption needs to be suppressed by adjusting frame rates.
Innovation Solution
A display device with a scanning circuit and a control circuit that allows for seamless switching between display modes by starting the operation unit from a specific scanning sequence, ensuring continuous and natural image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the frame rate is raised to improve image quality, then the image quality is improved, but the power consumption increases
Solution Approach 1:
The display device dynamically switches between different display modes (first display mode with higher frame rate and second display mode with lower frame rate) based on operational conditions. The control circuit adjusts the scanning sequence and frame rate in real-time, allowing the system to optimize between image quality and power consumption by adapting the display performance to current usage scenarios.
2Use of energy by moving object
If the display mode is switched to suppress power consumption, then the power consumption is suppressed, but the switching may give a sense of unnaturalness to the user
Solution Approach 1:
The control circuit is configured to start the operation unit from a specific scanning sequence (first scanning sequence) when switching to the first display mode. This preliminary positioning of the scanning sequence ensures that the image display continues seamlessly without interruption or visible artifacts during mode transitions, preventing the unnatural sensation that would otherwise occur when switching between different frame rates.
3Use of energy by moving object
If the scanning sequence is not properly managed during mode switching, then the power consumption can be reduced, but the image display may be interrupted
Solution Approach 1:
The control circuit maintains continuous image display during display mode switching by carefully managing the scanning sequence transitions. When switching between the first and second display modes, the system ensures that the scanning operation continues without interruption by starting from the appropriate scanning sequence point, thereby maintaining the reliability and continuity of the image display while still achieving power consumption reduction through mode switching.

AI summary
A display device comprising a scanning circuit configured to scan a pixel array in which a plurality of pixels are arranged in a matrix and a control circuit configured to control the scanning circuit to scan the pixel array in accordance with a display mode selected among a plurality of display modes is provided. The plurality of display modes include a first display mode for repeatedly performing an operation unit formed by a plurality of scanning sequences including a first scanning sequence by which the scanning circuit scans, in a predetermined order, a predetermined scanning line of the pixel array. When shifting to the first display mode from a display mode which is other than the first display mode among the plurality of display modes, the control circuit controls the scanning circuit to start the operation unit from the first scanning sequence.
