Support Frame Protrusion for Narrow Bezel Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellphone designs with a separate rubber frame to support the backlight module hinder the narrowing of the frame, which limits the display area and makes large-screen cellphones cumbersome to hold and operate with one hand.
Innovation Solution
A support frame with a protrusion that accommodates the backlight module, eliminating the need for a separate rubber frame, allowing for a narrower frame design by integrating the backlight module under the protrusion and using light shielding adhesive for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate rubber frame is used to support the backlight module, then the backlight module can be securely supported, but the frame width increases and the display area decreases
Solution Approach 1:
The patent merges the support function into the middle frame itself by creating a protrusion that integrates both the structural support function and the backlight module accommodation. This eliminates the need for a separate rubber frame, thereby reducing frame width and increasing display area while maintaining support stability.
Solution Approach 2:
The patent utilizes the thickness dimension of the middle frame by creating a protrusion with specific thickness requirements (at least equal to backlight module thickness). This dimensional approach allows the middle frame to provide support in a compact manner without increasing the planar frame width, thus preserving display area.
2Reliability
If a separate rubber frame is used to support the backlight module, then the backlight module can be securely supported, but the overall device structure becomes more complex
Solution Approach 1:
The patent combines multiple functions (structural support, backlight module mounting, and frame integrity) into a single middle frame component with an integrated protrusion. This eliminates the need for a separate rubber frame, reducing the number of parts and simplifying the overall device structure while maintaining support reliability.
Solution Approach 2:
The middle frame with the protrusion serves multiple functions simultaneously: it provides the main structural support, accommodates the backlight module, and eliminates the need for additional support components. This multi-functionality reduces device complexity while maintaining support stability.
3Area of stationary object
If the frame width is reduced for narrow frame design, then the display area increases, but the structural integrity and support capability may be compromised
Solution Approach 1:
The patent applies local quality by creating a protrusion with specific thickness requirements (at least equal to backlight module thickness) at the precise location where support is needed. This localized thickening provides structural integrity and support capability exactly where required, while the rest of the frame can maintain a narrow profile to maximize display area.
