Display Panel Region Power Control via Exposure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with folding axes between adjacent regions consume power even when the display surfaces are not exposed, leading to increased energy usage as users cannot view images.
Innovation Solution
A display panel with a driving circuit including pixel driving modules, gate driving modules, and control modules that connect or disconnect based on a control signal generated according to a setting parameter, such as ambient light intensity, to determine if the display surface is exposed, allowing regions to stop working when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display regions continue to operate when display surfaces are not exposed, then the display panel maintains readiness to display images, but power consumption increases unnecessarily
Solution Approach 1:
The patent implements dynamic control of display region operation states based on real-time exposure detection. Control modules dynamically switch between working and non-working states according to whether the display surface is exposed, making the system adaptive to changing conditions rather than static
Solution Approach 2:
The patent employs feedback mechanisms where detection modules continuously monitor whether display surfaces are exposed and feed this information back to control modules. The control modules then adjust the operation state of pixel driving modules accordingly, creating a closed-loop control system that responds to actual conditions
2Use of energy by moving object
If control modules are added to manage connection and disconnection of gate driving units, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent divides the display panel into multiple independent display regions, each equipped with its own control module. This segmentation allows independent control of each region's power state, enabling granular power management where only exposed regions remain active while non-exposed regions are disconnected
Solution Approach 2:
The control modules serve multiple functions: they detect exposure status, control connection/disconnection of gate driving units, and manage power distribution to pixel driving modules. This multi-functionality reduces the need for separate dedicated components for each function
