Flexible Display Visual Distortion Correction via Folding State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in electronic devices experience visual distortion when their state changes, such as during unfolding, folding, or intermediate positions, affecting the user's viewing experience.
Innovation Solution
An electronic device with a flexible display, a processor, a camera, a distance detection sensor, and a hinge structure that allows for unfolded, folded, and intermediate states. The device compensates for visual distortion by using user gaze information, folding information, and coordinate data to adjust the image display area accordingly.

Engineering Contradiction Analysis
1Volume of moving object
If the flexible display is folded to an intermediate state, then the device becomes more compact and portable, but visual distortion occurs on the display screen
Solution Approach 1:
The system performs preliminary actions by detecting the folding state before distortion becomes problematic. The folding detection sensor continuously monitors the angle between housing sides, and the processor pre-calculates the appropriate display area coordinates based on detected folding angles, preparing correction data in advance to prevent visual distortion before it affects the user experience.
Solution Approach 2:
The system implements feedback by using the folding detection sensor to continuously monitor the actual folding state and comparing it with stored reference data. The processor receives real-time folding angle information, retrieves corresponding corrected coordinate information from memory, and applies this feedback to dynamically adjust the display area, ensuring the display remains undistorted across all folding states.
2Manufacturing precision
If the display area is adjusted to compensate for distortion, then visual quality improves, but the effective display area may change
Solution Approach 1:
The system applies dynamics by making the display area adaptable and changeable based on the folding state. The processor dynamically adjusts the second coordinate information defining the display area boundaries according to the detected folding angle, allowing the display region to flex and transform with the device's physical state while maintaining visual quality through real-time coordinate recalculation.
3Measurement precision
If multiple sensors and processors are used to detect and correct distortion, then distortion compensation accuracy improves, but device complexity increases
Solution Approach 1:
The system implements universality by designing the processor to perform multiple functions: it processes images from cameras, analyzes data from distance detection sensors, detects folding states, calculates corrected coordinates, and controls display output. This multi-functional approach consolidates what could be separate specialized components into a single versatile processor, reducing overall device complexity while maintaining high measurement and compensation accuracy.
