Dynamic Touch Panel Frame Area Control for Multi-Device Display Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable information processing terminals with touch panels face issues of erroneous detection when held by users, as the frame around the display area narrows the screen size and makes it difficult to visually distinguish non-operable areas, leading to inefficient use and image discontinuity when multiple devices are used side by side.
Innovation Solution
An operation display apparatus with a control unit that switches specific areas on the display face between operable and non-operable states, using proximity sensors and load sensors to detect user interaction and device positioning, allowing the frame area to be set as non-operable when held by a user and operable when in contact with other devices, thereby preventing erroneous detection and maintaining image continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame is provided around the display area to prevent erroneous touch detection, then erroneous detection is prevented, but the display area is narrowed
Solution Approach 1:
The patent applies dynamics by making the frame area dynamically switchable between operable and non-operable states. The control unit changes the touch panel's responsiveness in the frame area based on detected usage scenarios (holding hand detection, proximity to other devices), allowing the same physical area to serve different functions under different conditions.
Solution Approach 2:
The patent changes the operational parameter of the frame area from fixed to variable. By detecting usage patterns and adjusting the touch sensitivity or responsiveness in the frame area accordingly, the system optimizes between preventing erroneous input and maximizing display area utilization.
2Reliability
If a part of the touch panel is set to an input non-operable area to prevent erroneous detection, then erroneous detection is prevented, but the area cannot be visually recognized as non-operable and is not efficiently utilized
Solution Approach 1:
The system dynamically adjusts the operational state of the frame area based on detected usage scenarios. When a holding hand is detected or when another device is nearby, the frame area becomes non-operable to prevent erroneous input. When no such conditions exist, the frame area becomes operable, allowing full utilization of the display area and improving efficiency.
Solution Approach 2:
The system uses sensors (proximity sensors, load sensors) to detect usage conditions and provides feedback to the control unit, which then adjusts the touch panel's operational state accordingly. This closed-loop feedback mechanism ensures the frame area's responsiveness matches the actual usage context.
3Area of stationary object
If multiple display apparatuses are disposed side by side to obtain a large display area, then display area is increased, but the frame at the joint causes image discontinuity
Solution Approach 1:
When multiple devices are disposed side by side and proximity is detected, the control unit dynamically changes the frame area adjacent to the other device into an operable state. This allows the display images to extend continuously across the frame boundary, eliminating visual discontinuity while maintaining the benefit of multiple devices being used together.
Solution Approach 2:
The frame area serves multiple functions: it acts as a protective border and erroneous input prevention zone when devices are used independently, but becomes an extended display area when devices are used together in proximity, enabling seamless multi-device display configurations.

Disclosed in an operation display apparatus including: a display unit; a touch panel to detect a touch position on which a display face of the display unit is touched; and a control unit to control display contents of the display unit and to switch a specific area provided in a part of the display face, between an operable state in which display of information and a detection of a touch action for the touch panel are operated and a non-operable state in which the display and the detection are not operated, wherein the control unit sets a part of the specific area, which is arranged in a boundary with another operation display apparatus disposed with the operation display apparatus side by side, to the operable state.
