Full-Window Touch Display Panel with Light Blocking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices limit touch input functionality to the display area and require separate components like FPC and IC for function keys in the non-display area, complicating the configuration and increasing thickness.
Innovation Solution
A display device with a touch screen panel covering the entire window, including a display area and non-display area, where a first light blocking member is used to define the non-display area, eliminating the need for separate FPC and IC for function keys and allowing decorative films to be omitted, thereby simplifying the configuration and reducing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate FPC and IC are used for function keys in the non-display area, then the function keys can be implemented, but the device configuration becomes complicated and thickness increases
Solution Approach 1:
The patent combines the function key capability directly into the touch screen panel by extending the touch sensing area into the non-display area. The touch screen panel now serves dual purposes: displaying images in the display area and providing touch input functionality in the non-display area where function keys are needed. This eliminates the need for separate FPC and IC components, simplifying the overall device configuration while maintaining full function key capability.
2Adaptability or versatility
If a separate FPC and IC are used for function keys in the non-display area, then the function keys can be implemented, but the device thickness increases
Solution Approach 1:
The patent merges the function key input functionality into the existing touch screen panel structure by extending the touch sensing area. This integration eliminates the need for additional separate components (FPC and IC) that would increase device thickness, thereby maintaining a thinner overall device profile while still providing full function key capability in the non-display area.
3Adaptability or versatility
If the touch screen panel is extended to cover the entire window including non-display area, then touch functionality is achieved across the entire window, but the structure becomes more complex
Solution Approach 1:
The patent makes the touch screen panel universal by enabling it to perform multiple functions: it serves as both the display interface in the display area and the touch input interface in the non-display area. This multi-functional design allows the single touch screen panel component to replace what would traditionally require separate components for display and touch input, thereby achieving full-window touch functionality without proportionally increasing structural complexity.
