Display Screen Gap Sealing With Absorption Member Against Grease Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External grease or water easily erodes display screens through gaps between the screen and the housing, causing yellow spots and deteriorating the display effect.
Innovation Solution
An electronic device with a bonding member having openings and an absorption member, including parts that absorb grease or water, is used to seal and waterproof the gap between the display screen and the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to bond the display screen to the housing, then the display screen is fastened to the housing, but a gap is formed at the sound output hole location causing grease or water to erode the display screen
Solution Approach 1:
The bonding member is divided into a bonding portion that bonds to the housing and an extension portion that extends toward the sound output hole. This segmentation allows the bonding member to provide strong bonding while creating a protective structure at the gap location without compromising the overall bonding strength.
Solution Approach 2:
The extension portion of the bonding member acts as an intermediary element between the bonding portion and the sound output hole. It fills the gap and prevents grease or water from directly contacting the display screen, while still allowing the bonding member to fulfill its bonding function.
2Strength
If adhesive is used to bond the display screen to the housing, then the display screen is fastened to the housing, but long-term accumulation of grease or water causes yellow spots on the display screen
Solution Approach 1:
The extension portion of the bonding member is positioned in advance to prevent grease or water from reaching the display screen before they can cause damage. This preliminary protective action stops contamination at the source, preventing yellow spots from forming over time.
Solution Approach 2:
The extension portion serves as a long-term protective intermediary that blocks the accumulation path of grease or water. By maintaining this protective barrier continuously, the display screen remains reliable and free from yellow spots despite prolonged exposure to potential contaminants.
3Strength
If adhesive is used to bond the display screen to the housing, then the display screen is fastened to the housing, but the display effect is severely affected due to grease or water erosion
Solution Approach 1:
By segmenting the bonding member into bonding and extension portions, the patent maintains strong bonding while creating a protective barrier that prevents grease or water from reaching the display screen, thus preserving display quality.
Solution Approach 2:
The extension portion acts as a protective intermediary that blocks harmful substances from reaching the display screen. This intermediary structure ensures that even though the display screen is bonded to the housing, it remains protected from grease or water that would otherwise degrade its display effect.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents erosion and long-term accumulation of grease or water, thereby improving the display screen's effectiveness.
Implementation Method 1
an absorption member, the absorption member includes at least a first part, and the first part is at least partially located in the opening... the first part can absorb the external grease or water

AI summary
Embodiments of this application provide an electronic device, and the electronic device includes at least a display screen and a housing. The housing includes a first region and a second region connected to the first region. A gap is formed between at least one end of the display screen and the first region, and a bonding member is disposed between the second region and a surface that is of the display screen and that faces the second region. There is at least one opening on the bonding member, and the opening is in communication with the gap. The electronic device further includes an absorption member, the absorption member includes at least a first part, and the first part is at least partially located in the opening. In this way, external grease or water can be prevented from eroding the display screen through the gap between the display screen and the housing, and a case in which long-term accumulation of the grease or water in the gap causes yellow spots on the display screen can be avoided, so that a display effect of the display screen can be improved to a great extent.
