Solution Overview

Problem

Conventional photoelectric display devices experience shortened lifespan due to frequent collisions between photoelectric media and seal agents when subjected to external forces, particularly in flexible panels, leading to premature wear and leakage.

Innovation Solution

Incorporating a photoelectric display medium trapping buffer region between the display region and seal material, featuring a gradient arrangement of grooves and spacer posts, which mitigates impact on the seal material and ensures effective damping, thereby prolonging the lifespan of the seal material and the entire device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flexible photoelectric display device is used to improve adaptability, then the device can be flexed during use, but the photoelectric media flow more frequently and collide with seal agent, shortening device lifetime

Engineering Contradiction:

ImproveflexibilityVSAvoiddevice lifetime

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a buffer region between the display region and seal material that is designed to absorb and cushion the impact of photoelectric media during flexing. This beforehand cushioning structure prevents the media from directly colliding with the seal agent, thereby protecting the device while maintaining flexibility.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The buffer region acts as an intermediary element between the photoelectric media and the seal material. When the device is flexed, this intermediate structure absorbs the shock and prevents direct contact between the media and seal agent, resolving the contradiction between flexibility and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the photoelectric display device is subjected to external force, then the device responds to the force, but photoelectric media collide with seal agent multiple times, shortening seal agent lifetime

Engineering Contradiction:

Improveresponse to external forceVSAvoidseal agent lifetime

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The buffer region is pre-configured to provide cushioning before the photoelectric media can collide with the seal agent. When external force is applied, the buffer absorbs the impact energy, preventing repeated collisions that would otherwise shorten the seal agent's lifetime.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent converts the harmful impact of photoelectric media colliding with seal agent into a beneficial cushioning effect. The buffer region is designed to absorb the impact energy, transforming what would be damaging repeated collisions into a controlled damping effect that protects the seal agent.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If no buffer region is provided, then the device structure is simpler, but impact on seal material by photoelectric media cannot be reduced, causing leakage

Engineering Contradiction:

Improvestructure complexityVSAvoidleakage prevention

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent segments the device structure by introducing a buffer region between the display region and seal material. This segmentation creates a dedicated zone for impact absorption, separating the functions of display and sealing while preventing direct contact between photoelectric media and seal agent during flexing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The buffer region provides beforehand cushioning by being positioned between the photoelectric media and seal material before any impact can occur. This pre-positioned cushioning structure prevents leakage by absorbing impact energy before it reaches the seal agent.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A substrate and a photoelectric display device comprising the substrate are provided. The substrate comprises a display region (11) and seal material disposed in a periphery thereof. The substrate further comprises a trapping buffer region (13) which is disposed between the display region (11) and the seal material and receives photoelectric display media. By providing the trapping buffer region, impact on the seal material by the excessive photoelectric display media can be mitigated or eliminated when the photoelectric display device is subjected to an external force or is flexed. The life time of the seal material is prolonged. A leakage of the photoelectric display media is avoided.
