Notch Display Sub-Regions for Touch Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile terminals face challenges in efficiently managing diverse functions and screen real estate, particularly with the introduction of bezel-less designs and notch designs, where sensor placement and functionality integration are complex, requiring innovative control methods to optimize user interaction and function execution.
Innovation Solution
A mobile terminal design featuring a notch region recessed into the main display area, with sub-display regions on either side, allowing a controller to process touch inputs differently based on their origin, enabling distinct functions and information display across these regions, including the notch region, to enhance user interaction and functionality management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch design is implemented to place sensors in the upper end region of the display unit, then sensor integration is achieved, but the display area is reduced due to the recessed region
Solution Approach 1:
The sub-display regions are designed to serve multiple functions: they can display information, accept touch inputs for different operations, and compensate for the display area lost to the notch region. The controller enables these regions to dynamically adapt their function based on touch input location and type.
2Area of stationary object
If the display region extends to the upper end including the notch region, then screen utilization is maximized, but control complexity increases due to multiple touch input regions
Solution Approach 1:
Different regions of the display unit are assigned different functions and control behaviors. The first and second sub-display regions have distinct functions from each other and from the main display region. The controller identifies which region received the touch input and executes region-specific operations, allowing complex functionality to be managed through simple spatial differentiation.
3Adaptability or versatility
If sub-display regions are created on either side of the notch region, then function differentiation is enabled, but the overall display coherence is compromised
Solution Approach 1:
The first and second sub-display regions are merged with the main display region to form a unified display unit that accepts touch inputs across all regions. The controller integrates the functionality of all regions, allowing seamless operation where touch inputs from any region trigger appropriate responses. This merging maintains display coherence while enabling function differentiation through the controller's region identification and response logic.

AI summary
Provided is a mobile terminal including a display unit in which a portion of an upper end of a display region is recessed. The mobile terminal includes a main body having a front surface and a rear surface, at least one sensor disposed on the front surface of the main body, a display unit including a main display region disposed at the front surface of main body and first and second sub-display regions extending from the main display region and disposed with the at least one sensor interposed therebetween, and a controller controlling at least one function in response to a touch input applied to the display unit, wherein the controller controls different functions on the basis of which of the main display region, the first sub-display region, and the second sub-display region, the touch input starts from.
