Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face a trade-off between anti-peeping functionality and light-emitting efficiency, with light-blocking patterns reducing efficiency and affecting service life.
Innovation Solution
A display panel design incorporating conductor portions and light-blocking structures that switch between light-emitting and non-light-emitting areas, allowing for anti-peeping and large-viewing angle modes without affecting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If light-blocking patterns are used to achieve anti-peeping functionality, then privacy protection is improved, but light-emitting efficiency deteriorates
Solution Approach 1:
The light-blocking structures are designed to be movable between a first position (overlapping light-emitting areas for anti-peeping mode) and a second position (non-overlapping for large-viewing angle mode). This dynamic positioning allows the display panel to switch between different functional modes, resolving the contradiction by making the light-blocking capability adjustable rather than fixed.
Solution Approach 2:
The light-blocking structures are divided into multiple independent elements that can be individually controlled by conductor portions. This segmentation allows selective positioning of light-blocking elements, enabling the system to achieve anti-peeping functionality only when needed while maintaining light-emitting efficiency in other areas and modes.
2Object-affected harmful factors
If light-blocking patterns are used to achieve anti-peeping functionality, then privacy protection is improved, but service life deteriorates
Solution Approach 1:
The movable light-blocking structures allow the display panel to switch between anti-peeping mode and large-viewing angle mode. By making the light-blocking capability dynamic rather than permanent, the system can extend service life by operating in the more efficient large-viewing angle mode when privacy protection is not required, reducing cumulative stress on the light-emitting components.
3Object-affected harmful factors
If light-blocking structures are positioned over light-emitting areas, then anti-peeping effect is improved, but light-emitting efficiency deteriorates
Solution Approach 1:
The light-blocking structures can be dynamically positioned to overlap with light-emitting areas only when anti-peeping mode is activated. When in large-viewing angle mode, the light-blocking structures are positioned away from the light-emitting areas, allowing maximum light emission efficiency. This resolves the contradiction by making the light-blocking effect conditional and reversible.
Solution Approach 2:
The conductor portions are selectively positioned to control light-blocking structures only in specific regions. The first conductor portions are located in light-emitting areas to control anti-peeping functionality, while second conductor portions are located in non-light-emitting areas. This local differentiation allows anti-peeping effect to be achieved only where needed without compromising overall light-emitting efficiency.
