Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable flat panel display apparatuses have small input areas, leading to mistyping issues due to their compact design, which increases manufacturing costs when additional sensing elements are added to compensate for errors.
Innovation Solution
A switching complex with a first switch on the display part for generating a signal based on grip position and a second switch on the corner for generating a signal based on bending, allowing for input signal generation without the need for additional sensing elements, using a Look-Up-Table to correlate these signals into input data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensing elements are added to the display apparatus to improve input accuracy, then measurement precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The flexible display panel serves multiple functions: it acts as both the display surface and the sensing element for detecting grip position and bending state. The display panel itself becomes the input device, eliminating the need for separate sensing components while maintaining input accuracy.
Solution Approach 2:
The display apparatus uses its own structural properties (flexibility and position) to generate input signals. The grip position and bending state of the display panel itself provide the necessary sensing information without requiring external or additional sensing elements.
2Measurement precision
If additional sensing elements are added to the display apparatus to improve input accuracy, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The display panel serves multiple functions: it acts as both the display surface and the sensing element for detecting grip position and bending state. The display panel itself becomes the input device, eliminating the need for separate sensing components while maintaining input accuracy.
Solution Approach 2:
The sensing function is merged with the display panel structure. The grip position sensor and bending state detector are integrated into the display panel itself, combining multiple functions into a single component to reduce manufacturing complexity and cost.
3Ease of operation
If the input area is increased to reduce mistyping, then ease of operation is improved, but device size increases
Solution Approach 1:
The input interface extends beyond the traditional 2D surface into the 3D space by utilizing the bending dimension. The bending state of the flexible display panel adds a new dimension for input, allowing for more input possibilities without increasing the footprint of the device.
Solution Approach 2:
The input mechanism transitions from static button presses to dynamic bending actions. The flexible display panel's ability to bend and change shape provides a dynamic input method that is more intuitive and less error-prone while maintaining a compact form factor.

AI summary
A switching complex including first and second switches is disclosed. The first switch is formed on a display part of the overall display so as to generate a first switching signal based on a grip position. The second switch is formed on a corner of the display part to generate a second switching signal based on bending of the corner of the display part while the first switching signal is generated. Therefore, input is simplified, and switching errors are reduced.
