Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses, particularly those using LCD panels, face challenges in achieving a slim or thin design while maintaining or improving functionality and color reproducibility, as they require optimization of the structure and layout of backlight units and optical sheets.
Innovation Solution
The implementation of a display module that includes a quantum dot (QD) sheet between the light guide plate and the display panel, supported by guide members that align and fix the light guide plate and QD sheet within a chassis, enhancing color reproducibility and allowing for a narrow bezel design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a QD sheet is added to improve color reproducibility, then color reproduction is enhanced, but device complexity increases
Solution Approach 1:
The guide member integrates multiple functions: it guides the light guide plate, guides the QD sheet, and supports both components simultaneously. This merging of guidance and support functions into a single structure reduces the number of separate components needed, thereby improving color reproducibility through QD sheet integration while minimizing the increase in device complexity
Solution Approach 2:
The guide member is designed as a multi-functional component that performs guidance for both the light guide plate and QD sheet, as well as providing support for both components. This universal design approach allows the system to accommodate the additional QD sheet for improved color reproduction without proportionally increasing overall structural complexity
2Manufacturing precision
If multiple optical sheets including QD sheet are added, then color reproducibility is improved, but the thickness of the display module increases
Solution Approach 1:
The QD sheet is implemented as a thin film structure that can be integrated between the light guide plate and display panel. This thin-film approach allows the QD sheet to contribute to color reproducibility while minimizing the increase in overall module thickness, as the sheet itself adds minimal dimensional bulk
Solution Approach 2:
The guide member extends in the thickness direction to provide guidance and support functions, effectively utilizing the available vertical space. By designing the guide structure to extend vertically with guide portions and seating portions, the system accommodates multiple optical layers without requiring excessive horizontal expansion, thus managing thickness efficiently
3Manufacturing precision
If guide members are added to align light guide plate and QD sheet, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The guide member combines multiple guidance functions into a single integrated structure. Rather than adding separate guide components for the light guide plate and QD sheet, the design merges these functions into one guide member with multiple guide portions, achieving precise alignment while minimizing the increase in component quantity
Solution Approach 2:
The guide member is designed as a universal component that performs alignment and support functions for both the light guide plate and QD sheet simultaneously. This multi-functional design reduces the need for separate specialized components, thereby improving alignment precision without proportionally increasing device complexity

AI summary
A display module and a display apparatus having the display module are provided. The display module includes a light guide plate which turns a path of generated light and emits the light through an emitting surface, a quantum dot (QD) sheet provided to correspond to the emitting surface to improve color reproducibility of the light emitted from the light guide plate, and at least one guide member which is fixed inside of a chassis and supports the light guide plate and the QD sheet. Using such a configuration, the color reproducibility of the display module may be improved, and the light guide plate and the QD sheet may be fixed together.
