Solution Overview
Problem
Touch operations on devices with touch screens are often inaccurate due to small control icons and high content density, leading to frequent mistaken interactions.
Innovation Solution
An electronic device with a deformable display unit, a touch sensing unit, and an adjustment unit that deforms the display based on predetermined rules to highlight control buttons, allowing for easier identification and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large quantity of content is displayed on the touch screen, then the information density is improved, but the control icon size becomes small leading to inaccurate touch operations
Solution Approach 1:
The display unit transitions from a static flat state to a dynamic three-dimensional deformed state when control buttons are detected. The adjustment unit actively changes the display surface morphology to create raised or recessed regions at control button positions, transforming the interface from a uniform plane to a dynamically adaptable surface that enhances touch precision without reducing content quantity.
Solution Approach 2:
The display unit applies different local properties to different regions: control button regions are deformed to create distinct three-dimensional features (raised or recessed), while other display areas remain flat. This local differentiation allows users to easily identify and accurately touch control buttons amidst dense content display, resolving the contradiction between high information density and touch accuracy.
2Measurement precision
If control buttons are made larger to improve touch accuracy, then the touch operation accuracy is improved, but the display content quantity is reduced
Solution Approach 1:
Instead of increasing control button size in the two-dimensional display plane (which would reduce content quantity), the invention adds a third dimension by deforming the display surface to create raised or recessed regions. This vertical dimensionality change allows control buttons to be distinguished by tactile feedback and visual perspective without occupying more horizontal space, thus maintaining high display content quantity while improving touch accuracy.
3Ease of operation
If the display unit is deformed to highlight control buttons, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The adjustment unit serves as an intermediary component between the controller and the display unit. It receives control signals from the controller and translates them into physical deformations of the display surface. This intermediary structure simplifies the overall system architecture by separating the control logic from the deformation mechanism, making the system easier to manufacture and maintain despite the added functionality.

AI summary
An electronic device and a control method are provided. The electronic device includes a display unit, a touch sensing unit, an adjustment unit and a controller. At least a first portion of the display unit is deformable, and the first portion deformed has a deformation distance with respect to a first side or a second side of a plane where the display unit is located. The adjustment unit triggers deformation of the first portion of the display unit. The controller determines a control button in display content and a display position of the control button on the first portion of the display unit, and controls the display unit to be deformed at the display position according to a predetermined deformation rule by means of the adjustment unit. The touch sensing unit detects contact information generated by touching the control button by a user.
