Touch Determination on Laminated Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with touch panels struggle to accurately determine which operation is given to multiple layered display panels, leading to confusion and inefficiency in user interactions.
Innovation Solution
A display device with multiple laminated display panels and a capacitive touch panel, where a controller determines the specific panel for touch operations based on display features and touch gesture patterns, allowing for precise processing of user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display panels are laminated to provide diverse information display, then display functionality and information provision are improved, but it becomes difficult to determine which panel the touch operation is intended for
Solution Approach 1:
The display system is segmented into multiple independently controllable display panels (first display unit and second display unit). Each panel can display different types of information and respond to touch operations independently. The controller identifies which specific panel the touch operation targets and processes the input accordingly, allowing diverse display functionality while maintaining precise touch operation recognition.
2Device complexity
If a single touch panel is used for multiple display panels, then device complexity is reduced, but touch operation accuracy decreases
Solution Approach 1:
The controller acts as an intermediary between the single touch panel and multiple display panels. When a touch operation is detected on the touch panel, the controller determines which display panel the operation is intended for based on the touch position and panel display states, then routes the operation to the appropriate panel. This mediator approach maintains simple hardware structure while achieving accurate touch operation identification.
3Speed
If both display panels are always on to ensure responsiveness, then user interaction speed is improved, but power consumption increases
Solution Approach 1:
The display system dynamically adjusts the operational state of each display panel based on current usage conditions. The controller can switch panels between active and inactive states, activating only the necessary panel when touch operations are detected or when specific display functions are needed. This dynamic state adjustment maintains fast response speed for user interactions while significantly reducing power consumption during idle periods.

AI summary
A display device includes a display, a touch panel and a controller. The display includes a plurality of display panels laminated on one another. The touch panel is provided on a screen of the display and accepts touch operation. The controller determines with respect to which display panel among the plurality of display panels the touch operation is carried out, and carries out a process corresponding to operation content of the touch operation on the determined display panel.
