Display Device Disassembly System Using Cooling and Separation Stick
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disassembling display devices often result in damage to the display panel and window due to air bubbles, foreign materials, or misalignment during the separation process.
Innovation Solution
A system comprising a supporting part, window fixing part, display panel stopper, window pressurizing part, and separating stick, which cools the display device to reduce adhesive strength, applies pressure to fix and separate the window, and inserts a stick to completely separate the panel and window while minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disassembly methods are used to separate display panel and window, then separation can be achieved, but damage occurs to the display panel and window due to air bubbles, foreign materials, or misalignment
Solution Approach 1:
The system applies cooling to the adhesive film before separation to reduce its adhesive strength, and positions the separating stick in advance at the edge of the adhesive film. These preliminary actions prevent damage during separation by preparing the adhesive and separation tools in advance under controlled conditions.
Solution Approach 2:
The separating stick acts as an intermediary tool inserted between the display panel and window to gradually separate them. The system includes a separating stick insertion unit that precisely inserts and moves the separating stick along the adhesive film edge, preventing direct contact and damage between the panel and window.
Solution Approach 3:
The system changes the temperature parameter by cooling the adhesive film to reduce its adhesive strength. This parameter change allows for easier and damage-free separation of the display panel and window by modifying the physical properties of the adhesive under controlled temperature conditions.
2Productivity
If pressure is applied to separate the display panel and window, then separation is achieved, but misalignment and damage occur
Solution Approach 1:
The system uses a suction unit to automatically suck and hold the display panel, and a support unit to support the window, eliminating the need for manual positioning. The separating stick insertion unit automatically inserts and moves the separating stick along the adhesive film edge, achieving precise alignment and separation without manual intervention.
Solution Approach 2:
The system replaces manual mechanical manipulation with automated units: a suction unit uses vacuum pressure to hold the display panel, a support unit provides structured support for the window, and a separating stick insertion unit uses controlled mechanical motion to separate the components. This substitution ensures precise alignment and prevents misalignment damage.
3Strength
If adhesive strength is maintained during separation, then bonding is preserved, but damage occurs to components
Solution Approach 1:
The system applies cooling locally to the adhesive film rather than to the entire display device, reducing adhesive strength only where needed for separation. The separating stick is inserted locally at the edge of the adhesive film and moves along the edge, applying separation force only at the interface between the display panel and window, preserving component integrity while achieving separation.
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
Effectively separates the display panel and window while preventing damage by reducing adhesive strength through cooling and controlled pressure application, allowing for efficient disassembly without damaging either component.
Implementation Method 1
a cooling part positioned below the supporting part and configured to cool the supporting part
Implementation Method 2
A window pressurizing part is configured to apply pressure to the second region of the window along a first orthogonal to an upper surface of the supporting part
Implementation Method 3
An elastic member may be coupled to the contact plate. The contact plate may adsorb and fix the display panel

AI summary
A system for disassembling a display device includes a supporting part facing a window and supporting at least a portion of the window. A window fixing part is disposed on the supporting part and is configured to fix a position of the window with respect to the supporting part. A display panel stopper is positioned above the supporting part and is spaced apart from the supporting part by a predetermined distance. A window pressurizing part is configured to apply pressure to the second region of the window along a first orthogonal to an upper surface of the supporting part. A separating stick is movable along a second direction which intersects the first direction. The separating stick is configured to be inserted between the window and a display panel adhered to the window.
