Flexible Display Capacitance Detection for Partial Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flexible electronic devices, the entire display is often activated when only a portion is exposed, leading to unnecessary power consumption and a less pleasing user experience due to the inability to selectively control display regions based on the device's state.
Innovation Solution
An electronic device with a first and second housing, conductive regions, and a display that uses capacitance values to determine the externally exposed region, activating only that area and deactivating the rest, thereby reducing power consumption and enhancing user interface effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire display is activated in flexible electronic devices, then the display can show content in any state, but unnecessary power consumption occurs when only a portion is exposed
Solution Approach 1:
The display is divided into multiple independent regions that can be selectively activated. The processor identifies the exposed region and activates only that specific segment while keeping other segments inactive, enabling partial display activation to reduce power consumption.
Solution Approach 2:
Instead of activating the entire display, the system applies partial action by activating only the necessary exposed portion of the display. This partial activation matches the actual viewing area, eliminating energy waste on hidden regions.
2Adaptability or versatility
If the entire display is activated, then all regions can display content, but user experience deteriorates due to inability to selectively control display regions
Solution Approach 1:
The display activation is made dynamic by continuously monitoring the device state and adjusting which regions are active. As the flexible display extends or retracts, the processor dynamically identifies the new exposed region and updates the activation state accordingly, providing adaptability while conserving energy.
Solution Approach 2:
The system uses feedback from device state detection to control display activation. The processor receives information about the current state (exposed vs. retracted) and uses this feedback to determine which display regions should be active, creating a closed-loop control system that optimizes energy usage.
3Use of energy by stationary object
If capacitance values are used to determine exposed region, then selective display activation is achieved, but device complexity increases
Solution Approach 1:
The system uses self-service by leveraging the inherent capacitance properties of the flexible display structure itself. The display's own electrical characteristics are utilized to detect its state, eliminating the need for separate complex sensing mechanisms and keeping the added complexity minimal.

The at least one processor identifies a capacitance value, based on an overlapped region of the first conductive region and the second conductive region, and determines an externally exposed region of the display, based on the identified capacitance value, and controls the region determined to be exposed outside, to an activated state, and controls the remaining region except the region determined to be exposed outside, to an inactivated state. In addition to this, various embodiments identified through the specification are possible.
