Dual Display Mobile Terminal Active State Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in distinguishing between the first and second display surfaces of a mobile terminal device due to their identical shapes, leading to confusion about which surface they are operating on.
Innovation Solution
Incorporating a first and second display module, detecting modules, an executing module, and a control module that differentiate between active and inactive states of the display surfaces by displaying distinct visual cues such as bar images, brightness, or size differences, and controlling touch key illumination based on user input and processing states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two display surfaces have the same shape, then the device structure is simple and symmetric, but the user has difficulty telling which display surface they are operating on
Solution Approach 1:
The patent applies local quality by giving each display surface distinct visual characteristics in specific local areas. The first display surface has a first icon arranged in a predetermined area, while the second display surface has a second icon in a corresponding area. These localized differences allow users to easily distinguish between the two otherwise identical display surfaces, solving the identification problem without changing the overall symmetric structure.
Solution Approach 2:
The patent utilizes color changes by displaying icons with different colors or visual appearances on the two display surfaces. The first icon and second icon are displayed in colors that differ from each other, providing a clear visual cue for users to identify which surface they are operating on. This approach maintains structural simplicity while effectively solving the display surface differentiation issue.
2Volume of moving object
If display surfaces are made identical in shape and size, then manufacturing is easier and the device is more compact, but users cannot easily distinguish operation targets
Solution Approach 1:
The patent applies segmentation by dividing the display information into distinct segments - specifically, placing different icons in predetermined areas of each display surface. The first display surface shows a first icon while the second display surface shows a second icon, creating clear informational segmentation that helps users understand which surface is the active operation target, thus preventing loss of operational state information.
Solution Approach 2:
The patent uses icons as intermediary elements that mediate between the identical display surfaces and the user. These icons serve as visual mediators that convey operational state information without requiring the display surfaces themselves to be different in shape or size. The icons act as intermediaries that carry the distinguishing information needed for user identification.

AI summary
A cellular phone includes a first display; a second display; and a CPU which executes a first processing and a second processing according to an input with respect to a display detected by the panel sensors, and displays screens based on the first processing and the second processing on the display, respectively. The CPU executes a control for distinguishing the display displaying the screen in an active state from the display displaying the screen in an inactive state with respect to at least one of the display.
