Portable Computer Display Structure With Borderless Edge Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computer displays face challenges in mounting fragile structures securely within the housing, leading to potential damage and an unsightly bulkiness when conventional methods are used, and eliminating certain structures results in an overly fragile display.
Innovation Solution
The display module is mounted with a color filter glass layer and a thin-film transistor substrate layer, where the peripheral edges of these layers extend laterally to form an overhanging structure that rests on housing edges without intervening chassis members, and an opaque border is formed using black ink to conceal unsightly portions, allowing for the elimination of cover glass layers and integration of electronic components like cameras and sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional mounting structures are used, then the display is protected from damage, but the housing becomes bulky and unsightly
Solution Approach 1:
The patent removes the traditional chassis members that provided structural support and mounting functions. By extracting these intermediate structural elements, the display module can mount directly to the housing, eliminating the bulky intermediate structures while maintaining protection through the display module's own reinforced edges.
Solution Approach 2:
The patent merges the mounting function with the display module itself by having the peripheral edges of the color filter glass layer and thin-film transistor substrate layer extend laterally to form an overhanging structure that directly rests on the housing edges. This integration eliminates the need for separate chassis members and reduces overall bulk.
2Shape
If certain structures are eliminated to reduce bulk, then the housing becomes sleeker, but the display becomes overly fragile
Solution Approach 1:
The patent applies preliminary reinforcement to the display module's peripheral edges before mounting. The color filter glass layer and thin-film transistor substrate layer are designed with extended peripheral edges that form an overhanging structure, providing built-in structural strength and protection before the module is installed in the housing.
Solution Approach 2:
The patent employs composite construction by combining the color filter glass layer with the thin-film transistor substrate layer, where both layers extend laterally beyond the active display area. This composite structure creates a reinforced perimeter that provides mechanical strength and protection while maintaining the sleek housing design.
3Shape
If cover glass layers are eliminated, then the display achieves a borderless appearance and reduced thickness, but structural support is reduced
Solution Approach 1:
The patent makes the peripheral edges of the color filter glass layer and thin-film transistor substrate layer serve multiple functions: they provide structural support, form the overhanging mounting structure, and create the borderless appearance. By making these edges multi-functional, the patent eliminates the need for separate cover glass layers while maintaining both structural integrity and aesthetic appeal.

AI summary
An electronic device housing may have upper and lower portions that are attached with a hinge. At least one portion of the housing may have a rear planar surface and peripheral sidewalls having edges. A display module may be mounted in the housing. The display module may have glass layers such as a color filter glass layer and a thin-film transistor substrate. The color filter glass layer may serve as the outermost glass layer in the display module. The edges of the display module may be aligned with the edges of the peripheral housing sidewalls to create the appearance of a borderless display for the electronic device. The display module may be provided with an opening that allows a camera or other electronic components to receive light. Traces may be provided on the underside of the thin-film transistor substrate to serve as signal paths for the electrical components.
