Display Panel Chassis Corner Recesses for Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses face damage and deterioration in appearance quality due to impacts, such as drops, caused by collisions between the display panel and the chassis member, which are mitigated by enlarging the gap between them, leading to an increased bezel width.
Innovation Solution
The chassis member incorporates recessed portions in the corner wall sections of the standing wall to minimize collisions and reduce bezel width, using arc-shaped recessed portions in the horizontal walls and potentially in vertical walls to distribute impact stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sufficient gap is left between the display panel and the standing wall to prevent collision, then damage from impact is avoided, but the bezel width increases and appearance quality deteriorates
Solution Approach 1:
The standing wall is designed with different local structures: corner wall sections with recessed portions at corners where collision risk is high, and flat wall sections in between maintaining normal distance. This localized structural differentiation allows minimal gap overall while providing protective recesses at critical corners, resolving the contradiction between narrow bezel and impact resistance.
2Shape
If the gap between the display panel and the standing wall is reduced to improve appearance, then bezel width decreases and appearance quality improves, but collision damage risk increases
Solution Approach 1:
Recessed portions are pre-formed in the corner wall sections of the standing wall before impact occurs. These recesses create buffer spaces that absorb collision energy and prevent direct contact between the display panel corner and the standing wall corner, providing beforehand cushioning that mitigates damage risk while allowing reduced gap dimensions.
3Reliability
If the recessed portion is made deeper to better protect the display panel, then impact protection improves, but the standing wall structure becomes more complex and manufacturing difficulty increases
Solution Approach 1:
The recessed portions are designed with moderate depth that provides sufficient protection for normal drop scenarios without excessive depth. This partial action approach achieves adequate protection level while keeping the standing wall structure relatively simple and manufacturable, avoiding the complexity and cost of deeply recessed or overly complex protective structures.

AI summary
An electronic apparatus includes: a chassis member having an inner face, and a standing wall at an edge; and a display panel having a display surface, a rear face opposite the display surface, and an outer side face that stands between the display surface and the rear face, the rear face being supported by the inner face of the chassis member, the outer side face facing the standing wall of the chassis member. The display panel has a corner section on the outer side face. The standing wall has an inner wall face facing the outer side face of the display panel, and has a corner wall section on the inner wall face to go around the corner section. The corner wall section has a recessed portion recessed in a direction away from the corner section.
