Bezel Touch Sensor for Display Content Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Teachers using large display apparatuses face difficulties in distinguishing between writing on the screen and page manipulation, leading to unintentional selection or movement of lecture materials during presentations.
Innovation Solution
A display apparatus with a bezel touch sensor that detects touches and controls the display to create a folding area, allowing for intuitive movement and manipulation of content images based on touch location and duration, preventing accidental page transfers or selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large size display apparatus is used for lectures, then the display area and visibility are improved, but the distinction between writing on screen and page manipulation becomes unclear leading to unintentional operations
Solution Approach 1:
The patent divides the touch input area into two distinct zones: the display screen area for writing/annotation and the non-display bezel area for navigation control. This spatial segmentation allows teachers to clearly distinguish between writing operations (on screen) and page manipulation (on bezel), eliminating accidental operations while maintaining large display area for visibility.
2Ease of operation
If touch input is enabled on the display screen, then writing and annotation are convenient, but accidental page transfer or selection occurs during writing
Solution Approach 1:
The patent separates writing functionality (on display screen) from navigation functionality (on bezel area), so that writing operations cannot accidentally trigger page transfers. The spatial segmentation ensures that writing strokes remain confined to the screen area while navigation requires intentional touches on the distinct bezel area.
Solution Approach 2:
The bezel area acts as an intermediary zone that provides dedicated navigation control separate from the writing area. By placing page turn and selection controls on the bezel rather than the screen, the system creates a buffer zone that prevents writing operations from accidentally activating navigation functions.
3Reliability
If the bezel area is used for control input, then accidental screen operations are prevented, but the control interface complexity increases
Solution Approach 1:
The patent makes the bezel area multi-functional by enabling it to perform both touch-based navigation control and traditional button functions. The same bezel region can respond to different input types (touch, button press) and different gestures (tap, hold, drag), reducing the need for separate control mechanisms while maintaining operational reliability.
Solution Approach 2:
The patent merges the navigation control functions with the existing bezel structure, combining touch-sensitive controls with traditional button functionality in a single integrated area. This consolidation allows the system to provide reliable accident-free control without adding separate complex control interfaces.

AI summary
A display apparatus and a method of displaying an image by the display apparatus are provided. The display apparatus and the method include displaying a first content image on the display apparatus, detecting a first touch from a bezel of the display apparatus, displaying a folding area on a first edge of the first content image in response to a location of the first touch, and moving the first content image to the folding area from an adjacent folding area of the first content image, which contacts the folding area, in response to holding time of the first touch.
