Detachable Display Device With Release Layer For Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in disassembling and replacing touch and display modules in display devices with integrated touch functions, due to the need for removing front and rear housings and the bonding of these modules to glass with high-strength glue, complicates maintenance and repair processes.
Innovation Solution
A display device design featuring a frame with movable inner and outer components, anti-lock mechanisms, and strategically placed optical refractive strips, allowing for direct disassembly and replacement of glass and touch modules, while optimizing signal transmission paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the touch module and display module are bonded to glass with high-strength glue, then the bonding strength is improved, but the ease of repair deteriorates
Solution Approach 1:
The patent divides the bonding system into two parts: a permanent bonding layer (optical adhesive layer 40) that provides strong bonding, and a removable release layer (release layer 30) that enables easy separation. This segmentation allows the touch module and display module to be strongly bonded during normal use but easily separated when repair is needed, resolving the contradiction between bonding strength and ease of repair.
2Ease of operation
If the front and rear housings are removed to access touch and display modules, then the accessibility for repair is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the repair function from the housing removal process by introducing a release layer that enables direct access to the touch module and display module through the existing housing structure. This eliminates the need to remove front and rear housings for repair, maintaining accessibility while avoiding the complexity of housing disassembly and reassembly.
3Adaptability or versatility
If multiple components are disassembled for module replacement, then the replaceability is improved, but the time required for maintenance increases
Solution Approach 1:
The patent applies preliminary action by pre-applying the release layer to the glass substrate before assembling the touch module and display module. This preliminary preparation ensures that the release layer is already in position to facilitate easy separation, eliminating the need for time-consuming disassembly steps during maintenance and enabling quick replacement of modules.

AI summary
A display device includes an outer frame, an inner frame, and a glass. The inner frame is movably coupled to the outer frame, and the inner frame and the outer frame cooperatively define a glass receiving slot. One end of the glass is received in the glass receiving slot and clamped between the inner frame and the outer frame.
