Guide Frame Liquid Discharge for Display Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCDs and OLEDs, face corrosion issues due to liquid ingress, which can damage panel drivers and other metal elements during cleaning or moisture exposure.
Innovation Solution
Incorporating a guide frame with liquid discharging openings to direct any internal liquid to the outside, preventing corrosion by creating a circuit arrangement space that allows for the discharge of liquids and using a protrusion part to divert liquids away from sensitive areas, and optionally including a moisture-absorbing member to manage humidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the panel driver is disposed in the circuit arrangement space without liquid discharge structures, then the device structure is simple, but the panel driver is corroded by liquid that flows into the inside
Solution Approach 1:
The patent extracts the harmful liquid from the circuit arrangement space by introducing liquid discharge openings in the guide frame. These openings allow liquid to escape from the enclosed space where the panel driver is disposed, preventing corrosion while maintaining a relatively simple overall structure.
Solution Approach 2:
The guide frame acts as an intermediary structure between the external environment and the panel driver. By incorporating liquid discharge openings in the guide frame, it mediates the interaction with liquid, allowing controlled discharge while maintaining structural integrity and protecting the panel driver.
2Reliability
If liquid discharge openings are added to the guide frame, then liquid can be discharged from the circuit arrangement space, but the guide frame structure becomes more complex
Solution Approach 1:
The guide frame is segmented into functional regions: areas with liquid discharge openings for active liquid removal, and areas maintaining structural integrity for support. This segmentation allows the guide frame to perform multiple functions while managing complexity through organized functional distribution.
Solution Approach 2:
The guide frame serves multiple functions: structural support for the display panel, definition of the circuit arrangement space, and liquid discharge through integrated openings. This multi-functionality reduces the need for separate components, offsetting the added complexity of liquid discharge features.
3Reliability
If the circuit arrangement space is sealed to protect the panel driver, then corrosion is prevented, but liquid accumulation occurs inside the sealed space
Solution Approach 1:
Instead of completely sealing the circuit arrangement space, the patent converts the potential harm of liquid ingress into a beneficial discharge mechanism. The liquid discharge openings allow liquid to be actively removed from the space, transforming a sealed enclosure into a self-cleaning structure that prevents accumulation while maintaining protection.

AI summary
A display device capable of discharging liquid includes a display panel for displaying an image; a panel driver coupled to the display panel configured to drive the display panel; and a guide frame coupled to a rear surface of the display panel and supporting the display panel, wherein the guide frame defines a circuit arrangement space to accommodate the panel driver, and the guide frame has at least one liquid discharging opening through which liquid in the circuit arrangement space is discharged to an outside of the display device.
