Display Device Side Surface Extension to Bottom Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require a top chassis, which increases thickness and weight, and limits the integration of a backlight unit within the device, while also consuming more power and generating heat.
Innovation Solution
A display device design where the side surface of the display panel extends to a bottom chassis to omit the top chassis, allowing the display panel and backlight unit to be accommodated within the device, with a structure that includes inclined surfaces and adhesive members to secure the components, enabling efficient light distribution and reduced thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a top chassis is used in conventional display devices, then structural support and component mounting are improved, but device thickness and weight increase
Solution Approach 1:
The patent removes the top chassis from the display device structure, extracting the unnecessary component that was causing increased weight and thickness. The display panel's side surface is extended to provide structural support without requiring a separate top chassis, thereby reducing device weight while maintaining structural integrity.
Solution Approach 2:
The display panel's side surface is designed to serve multiple functions: it provides the display function, structural support, and component mounting surface. By making the side surface extend to the bottom chassis, it replaces the structural support function previously provided by the top chassis, achieving multi-functionality and reducing overall device weight.
2Ease of manufacture
If a top chassis is used in conventional display devices, then component mounting is improved, but device thickness increases
Solution Approach 1:
The patent merges the display panel structure with the mounting structure by extending the side surface to the bottom chassis. This integration allows components to be mounted directly on the extended side surface, eliminating the need for a separate top chassis and reducing device thickness while maintaining ease of manufacture.
Solution Approach 2:
The side surface of the display panel is extended in the vertical dimension to reach the bottom chassis, creating a new mounting surface that provides component mounting capability without increasing device thickness. This dimensional extension allows components to be mounted on the side surface rather than requiring a separate top chassis.
3Adaptability or versatility
If conventional display device structure is used, then component integration is limited, but power consumption increases and heat generation increases
Solution Approach 1:
The patent implements a nested structure where the backlight unit is positioned within the space defined by the extended side surface and bottom chassis. This nested arrangement improves component integration and adaptability, allowing for more efficient space utilization and potentially reduced power consumption through optimized component placement and heat dissipation.

AI summary
A display device includes a display panel which displays an image with light, the display panel including a first substrate, a second substrate facing the first substrate, and an image display layer disposed between the first and second substrates; a backlight unit which generates and provides the light to the display panel; and a bottom chassis facing the first substrate to dispose the second substrate therebetween and to define an inner space with the first substrate. The image display layer, the second substrate, and the backlight unit are accommodated in the inner space defined by the first substrate and the bottom chassis.
