Solution Overview
Problem
Current display devices face challenges in durability, convenience of assembly, and reliability of the light source, particularly in liquid crystal display devices.
Innovation Solution
The display device incorporates a backlight unit with a direct type light source configuration, including a reflective sheet with holes, a supporter for the diffusion plate, and an optical sheet for uniform light distribution, along with a frame that supports the components and protects internal parts, enhancing assembly convenience and light source reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a direct type light source configuration is used in the backlight unit, then assembly convenience is improved, but light source reliability may deteriorate
Solution Approach 1:
The reflective sheet is segmented by forming holes at positions corresponding to the light sources, creating distinct functional zones that separate the light emission areas from the reflective areas. This segmentation allows for easier assembly while maintaining reliability by preventing direct contact between the diffusion plate and light sources.
Solution Approach 2:
The supporter acts as an intermediary component between the diffusion plate and the light sources. It provides indirect support and positioning without creating direct contact, thereby maintaining light source reliability while enabling convenient assembly through the structured support system.
2Use of energy by moving object
If the diffusion plate is positioned close to the light sources, then illumination efficiency is improved, but durability deteriorates due to direct contact
Solution Approach 1:
The supporter provides beforehand cushioning by creating a protective barrier and maintaining an appropriate gap between the diffusion plate and light sources. This prevents direct contact and potential damage while still allowing efficient light transmission, thereby extending the durability of the light sources.
Solution Approach 2:
The reflective sheet exhibits local quality by having different structures in different areas: solid reflective regions for light redirection and holes at light source positions for heat dissipation and contact prevention. This localized structural variation optimizes both illumination efficiency and durability.
3Power
If the reflective sheet is made continuous without holes, then light reflection efficiency is improved, but light source reliability deteriorates due to direct contact
Solution Approach 1:
The reflective sheet is segmented by forming holes at positions corresponding to the light sources, creating distinct functional zones that separate the light emission areas from the reflective areas. This segmentation allows for easier assembly while maintaining reliability by preventing direct contact between the diffusion plate and light sources.
