Curved Display Power Management via Segmented Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wraparound display devices consume more power due to their larger screen size compared to traditional display devices, necessitating a reduction in power consumption without compromising functionality.
Innovation Solution
The display panel is divided into different portions, with at least one portion operating in a power-saving mode by reducing brightness, updating frequency, or turning off the screen, while other portions remain in a normal display mode, allowing for efficient power management.

Engineering Contradiction Analysis
1Use of energy by moving object
If the display panel is divided into different portions with selective power-saving modes, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The display panel is divided into multiple independent display portions (first display portion, second display portion, side display portion) that can be controlled separately. Each portion can operate in different modes (normal display mode or power-saving mode) independently, allowing selective power management without affecting the entire display system.
Solution Approach 2:
The display portions can dynamically switch between normal display mode and power-saving mode based on operational requirements. The system adapts its power consumption characteristics by adjusting the operational state of different display portions in real-time, enabling flexible power management.
2Area of stationary object
If the wraparound display device uses a larger screen size, then display functionality is improved, but power consumption increases
Solution Approach 1:
The large wraparound display is segmented into multiple portions that can be independently controlled. By dividing the large screen into separate display areas, the system can activate only the necessary portions while keeping others in power-saving mode, thereby reducing overall power consumption despite maintaining large total display area.
Solution Approach 2:
Different portions of the display panel are assigned different operational qualities - some portions operate in normal display mode with full brightness and refresh rates, while other portions operate in power-saving mode with reduced brightness or lower update frequencies. This local differentiation allows the large screen to maintain functionality where needed while conserving energy in less critical areas.
