Flat Display Panel Buffer Member Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel display devices face weak impact resistance due to step differences in substrates, which are unsupported and vulnerable to external impacts.
Innovation Solution
A flat display panel design incorporating a buffer member on the outer sides of the bonding unit and a planarizing member to address the step differences, enhancing impact resistance by interposing a buffer member between the support member and the step differences.

Engineering Contradiction Analysis
1Reliability
If a support member supports the substrate at the pad unit area, then the substrate is properly supported, but a predetermined space is created due to step difference, resulting in low impact resistance
Solution Approach 1:
A buffer member is introduced as an intermediary element between the support member and the substrate. This buffer member fills the predetermined space created by the step difference, providing continuous support and improving impact resistance without interfering with the pad unit's electrical connections or the substrate's structural integrity.
Solution Approach 2:
The solution addresses the step difference problem by adding a component in the vertical dimension (Z-axis) rather than trying to modify the horizontal dimensions. The buffer member extends into the space created by the step difference, effectively compensating for the height discrepancy and providing support at the previously vulnerable area.
2Ease of operation
If substrates of different sizes are used to accommodate the pad unit, then the pad unit can be exposed outwardly for connections, but step differences are created on other substrate portions, reducing impact resistance
Solution Approach 1:
The buffer member serves as a mediator that reconciles the size difference between the two substrates. By positioning the buffer member at the step difference location, it provides mechanical support and impact resistance without interfering with the pad unit's exposure and connectivity function on the larger substrate.
Solution Approach 2:
The buffer member is specifically positioned only at the location where the step difference exists, providing localized support exactly where needed. This localized approach improves impact resistance at the vulnerable area without affecting the overall design or the pad unit's accessibility on the exposed substrate area.

AI summary
A flat display panel is constructed in such a manner that weak impact resistance of a substrate, due to a step difference present on the flat display panel, is prevented. The flat display panel includes: a substrate; a facing member bonded to the substrate, and having a surface area smaller than that of the substrate; a display unit disposed between the substrate and the facing member; a bonding unit which bonds the substrate and the facing member, and which is interposed between the substrate and the facing member along outer sides of the display unit; and a buffer member included on outer sides of the bonding unit of the substrate.
