Flexible Display Control with Bent Area Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible touch screen displays in electronic devices are disadvantaged as users cannot clearly see contents or easily make inputs at bent portions, leading to difficulties in usability and portability.
Innovation Solution
A method and apparatus for controlling flexible displays that determine the presence of bent areas, calculate coordinates and angles, and compensate displayed data using preset compensation to enhance visibility and input accuracy, allowing users to easily interact with the screen even when bent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is bent to improve portability, then the display can be folded and carried easily, but the user cannot clearly see contents or easily make inputs at the bent portion
Solution Approach 1:
The patent changes the display parameters (coordinates, angles, positioning) based on the detected bending state. The processor calculates compensation values according to the bent area and bent angle, then adjusts the display coordinates and positioning to maintain accurate touch input functionality regardless of the display's bending state
Solution Approach 2:
The patent implements a feedback mechanism where the display detects its own bending state through sensors, calculates the bent area and angle, and uses this information to dynamically adjust the display coordinates and positioning. This closed-loop feedback ensures that touch inputs remain accurate even when the display is bent
2Adaptability or versatility
If a flexible display is bent to improve portability, then the display can be folded and carried easily, but the user cannot clearly see contents at the bent portion
Solution Approach 1:
The patent adjusts display parameters including positioning and coordinates based on the detected bending state. By calculating compensation values according to the bent area and angle, the system repositions displayed content to account for the bending distortion, maintaining clear visibility of contents across the entire display surface
3Measurement precision
If compensation data is calculated and applied to bent areas, then display accuracy is improved, but device complexity increases
Solution Approach 1:
The patent pre-calculates and stores compensation data for various bending states in a lookup table. When a bending state is detected, the system simply retrieves the pre-computed compensation values based on the bent area and angle, avoiding complex real-time calculations and reducing processing complexity while maintaining high display accuracy

AI summary
A method and an apparatus for controlling a flexible display, and an electronic device adapted to the method are provided. The method includes determining, when a user input is made while screen display data is displayed on the flexible display, whether the flexible display includes a bent area, calculating, when the flexible display includes the bent area, coordinates from the bent area and a bent angle, and compensating data displayed on the bent area with preset compensation and displaying the data.
