Dual-Display Touch Window Layout for Adaptive Key Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with input devices, such as keyboards, have fixed key markings that do not adapt to different modes, making it difficult to display input content effectively and can degrade the external appearance with multiple markings on a single keypad.
Innovation Solution
A mobile terminal design featuring a transmissive integrated window covering both display modules, a touch-sensing unit formed as a film, and a controller that outputs mark sets including numbers, characters, and symbols, allowing for touch input and adaptive key markings based on the device mode, with the touch-sensing unit located between the integrated window and the second display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a keyboard with fixed key markings is used, then the input device structure is simple, but it cannot adapt to different modes and degrades external appearance
Solution Approach 1:
The patent combines the display module and input device into an integrated structure where the display serves dual purposes. The display shows information while also functioning as the input interface, eliminating the need for separate physical keyboards with fixed markings. This merging allows the system to adapt to different modes by changing displayed content rather than changing physical hardware.
Solution Approach 2:
The display module is designed to serve multiple functions: displaying information and receiving user input. By making the display universal, it can adapt to different operating modes (camera, messaging, browsing, etc.) by presenting different virtual keyboards and input interfaces on the same physical surface, thereby achieving mode adaptability without increasing structural complexity.
2Adaptability or versatility
If multiple mark sets are placed on a single keypad, then adaptability to different modes is improved, but external appearance is degraded
Solution Approach 1:
Instead of having static multiple mark sets on physical keys, the patent uses dynamic virtual mark sets displayed on the screen. The mark sets can change, move, and adapt based on the current mode and user interaction. This dynamic approach maintains a clean external appearance while providing full adaptability to different modes through software-based interface changes.
Solution Approach 2:
The patent replaces the mechanical keyboard system with fixed physical keys and multiple mark sets with a digital display-based input system. The virtual keyboard and mark sets are rendered on the display module, allowing infinite adaptability without any physical changes to the device exterior. This substitution eliminates the compromise between appearance and adaptability.
3Shape
If a transmissive integrated window is used to cover display modules, then external appearance is improved, but touch sensing complexity increases
Solution Approach 1:
The patent merges the touch sensing function with the display module by integrating the touch sensing unit directly with the display structure. The transmissive integrated window serves as both the visual display surface and the touch input surface, with the touch sensing layer combined with the display layers. This integration maintains a clean external appearance while managing touch sensing complexity through unified design.

AI summary
A mobile terminal having an input device that performs an input operation in a touch manner is provided. The mobile terminal includes a first display module, a second display module located adjacent to the first display module, an integrated window located an outer portion of the first and second display modules, and a touch sensing unit located between the window and the second display module for sensing a touch applied to the window and applying an input signal. Marks for guiding input content can be varied and high capacity and high-density multimedia or communication information can be easily and quickly accessed or executed.
