Portable Terminal Dynamic Display Area Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminals with touch pads lack the ability to increase the number of display divisions beyond the initial two areas, limiting user convenience and flexibility in multitasking and image management.
Innovation Solution
A portable terminal with a display panel and touch pad that allows further division of the display surface by introducing a second boundary line based on touch operations, enabling the creation of additional display areas without requiring users to replace display objects, using an area management unit to determine and control these divisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display surface is divided into two display areas, then the user can view multiple images simultaneously, but the number of display divisions cannot be increased beyond two
Solution Approach 1:
The patent applies segmentation by allowing the display surface to be divided into multiple display areas (not limited to two). The area management unit dynamically creates and manages multiple display areas based on user touch operations, enabling flexible division into three or more areas when needed
Solution Approach 2:
The patent implements dynamics by making the number and configuration of display areas changeable through user interaction. The area management unit responds to touch operations to dynamically adjust the number of display areas, transitioning between two-area and multi-area configurations as needed
2Ease of operation
If more display areas are defined, then user convenience for multitasking is improved, but the control mechanism becomes more complex
Solution Approach 1:
The patent applies self-service by enabling users to directly control the division and configuration of display areas through intuitive touch operations on the display surface. Users can drag boundary lines and adjust display area configurations themselves without requiring complex control interfaces or additional input devices

AI summary
There is provided a portable terminal including a display panel having a display surface with a touch pad, an area management unit which defines a plurality of display areas formed by dividing the display surface, and a display control unit which performs control on an image display in each display area. In a state where two display areas are defined with a first boundary line, in response to a touch operation on the touch pad, the area management unit determines, based on a touch position of the touch operation, a second boundary line passing one point on the first boundary line and one point within a predetermined range from the touch position and defines two areas which are formed by dividing an object area of the two display areas with the second boundary line, as first and second display areas in place of the object area.
