Touch Panel Soft Key Array Transparency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The viewability of screen regions overlapping with the keyboard is low for users when performing input on a keyboard display device, as the keyboard is displayed opaquely or at low transparency during use, impairing the visibility of content on the screen.
Innovation Solution
A display device comprising a display section, a detection section, and a controller that detects user touch regions, matches them against stored patterns, and displays a soft key array only when a match is determined, allowing for improved visibility by positioning and sizing the soft key array based on the touch region to enhance user interaction without obstructing the main content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the keyboard is displayed on the touch panel to enable input operations, then ease of operation is improved, but viewability of the screen content is deteriorated due to opaque or low transparency display
Solution Approach 1:
The keyboard transparency is dynamically adjusted based on user interaction state. When the user touches the keyboard area, the transparency increases to allow viewing of screen content through the keyboard, and when not touched, it returns to a more opaque state for better input visibility. This dynamic adjustment resolves the contradiction between input visibility and screen viewability.
Solution Approach 2:
The transparency parameter of the keyboard display is changed based on touch detection. The controller adjusts the transparency parameter in response to touch input, allowing the keyboard to transition between opaque and transparent states. This parameter change enables the system to adapt to different operational states and resolve the viewability contradiction.
2Ease of operation
If the soft key array is displayed to provide input functionality, then ease of operation is improved, but the display region is reduced, affecting productivity
Solution Approach 1:
The keyboard is positioned in the depth dimension by making it transparent, allowing it to overlap with the screen content without occupying the same visual space. This dimensional transition from opaque to transparent enables the keyboard to coexist with the display content, maintaining both input functionality and screen visibility simultaneously.
Solution Approach 2:
The transparency of the keyboard is changed based on touch input, allowing it to transition between opaque and transparent states. This visual property change enables the keyboard to adapt to different operational states, providing input functionality when needed while maintaining screen viewability during normal operation.

AI summary
A display device (1) includes a display section (20), a detection section (30), a storage (40), and a controller (10). The detection section (30) detects a touch region (210) of the display region in which a user touches. The storage (40) stores therein a pattern (400). The controller (10) includes a determination section (101) and a display controller (103). The determination section (101) determines whether or not the touch region (210) matches the pattern (400). The display controller (103) causes the display section (20) to display a soft key array (220) upon the determination section (101) determining match.
