Touchscreen Segmentation Reduces Wiring Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized touchscreens experience input data delays due to wiring delays between detection regions and controllers, leading to malfunction.
Innovation Solution
A touchscreen is divided into multiple detection regions, each with its own controller, all connected to a central control device, reducing wiring delays and preventing malfunction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection region is divided into multiple regions with separate controllers, then wiring delay is reduced and malfunction is prevented, but device complexity increases
Solution Approach 1:
The detection region is divided into multiple independent detection regions, each with its own controller. This segmentation reduces wiring delay by localizing control functions closer to the detection elements, thereby preventing malfunction in large-sized touchscreens while maintaining manageable system complexity through modular architecture
2Loss of time
If thick wiring is used to reduce wiring delay, then signal transmission is improved, but manufacturing cost increases and transmittance decreases
Solution Approach 1:
By dividing the detection region into multiple segments with local controllers, the patent reduces wiring delay without requiring thick wiring. Each detection region is served by a nearby controller, shortening the wiring path and eliminating the need for costly thick wiring solutions while maintaining signal transmission quality
Solution Approach 2:
Local controllers act as intermediaries between the detection regions and the central control device. These intermediate controllers process signals locally, reducing the wiring distance and delay without requiring thick wiring, thereby avoiding increased manufacturing costs and maintaining transmittance

AI summary
Malfunction of a large-sized touchscreen is prevented. In particular, malfunction of a large-sized touchscreen is prevented by reduction of wiring delay between a detection region and a controller. In a touchscreen, in which a detection area is divided, including a plurality of detection regions and a plurality of sensors, controllers are provided for the respective divided detection regions, and all the controllers are electrically connected to one central control device. It is preferable that a wiring between each of the divided detection regions and the corresponding controller be shorter than a wiring between the controller and the central control device.
