Dual-Screen Calibration Using Touch Gesture Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of dual-screen devices is inefficient due to the need for cumbersome operations like plugging and unplugging a keyboard for screen calibration, which prolongs the time required for completing calibration in mass production.
Innovation Solution
A method is introduced to optimize the manufacturing setting process by defining a correspondence between a touch gesture and a confirmation signal in a dual-screen device, detecting the touch gesture during calibration, and outputting a confirmation signal when the gesture matches a predefined gesture, allowing the calibration of a second display without an external input device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyboard plugging and unplugging is used for screen calibration, then calibration can be completed, but manufacturing efficiency is reduced and the process becomes cumbersome
Solution Approach 1:
The patent extracts the confirmation signal input function from the external keyboard and relocates it to the touch screen itself. During calibration, users can directly perform confirmation operations on the touch screen without needing to plug and unplug an external keyboard, thereby eliminating the cumbersome external device connection while maintaining calibration functionality.
Solution Approach 2:
The touch screen is given multiple functions: it serves both as the display device and as the input confirmation device during calibration. By making the touch screen universal, the patent eliminates the need for separate external input devices like keyboards, simplifying the calibration process and improving manufacturing efficiency.
2Reliability
If external input devices are used during calibration, then confirmation signals can be input, but the manufacturing process becomes complicated
Solution Approach 1:
The patent merges the display function and input confirmation function into a single device - the touch screen. By combining these functions, the calibration process no longer requires separate external input devices, reducing manufacturing process complexity while ensuring reliable calibration completion through the integrated touch interface.
3Manufacturing precision
If separate screen calibration is performed for each display, then calibration accuracy is maintained, but calibration time increases
Solution Approach 1:
The patent implements preliminary action by performing the first display calibration completely before initiating the second display calibration. During the first display calibration, users can complete all calibration steps including confirmation operations directly on the touch screen without external devices. This preliminary completion of the first calibration establishes a foundation that streamlines the second calibration process, maintaining accuracy while reducing overall calibration time.

AI summary
A method for optimizing a manufacturing setting process of a dual-screen device includes defining a correspondence between a touch gesture and a confirmation signal in a dual-screen device; detecting the touch gesture during a calibration process for a first display of the dual-screen device; determining whether at least one operation gesture on the dual-screen device is the same as the defined touch gesture, and outputting the confirmation signal when the at least one operation gesture on the dual-screen device is the same as the defined touch gesture; and in response to the confirmation signal, continuing to calibrate a second display of the dual-screen device. When screen calibration is performed on a large number of dual-screen devices, there is no need to frequently plug and unplug a keyboard, thereby avoiding cumbersome manufacturing processes and improving production efficiency.
