Curved Display Bottom Sash Light Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses require a light guide plate to direct light from backlight units to the display panel, which adds complexity and bulk, whereas the described solution eliminates the need for such a plate by using a curved bottom sash to reflect light from backlight units to the display panel.
Innovation Solution
A curved display apparatus with a curved bottom sash disposed behind the display panel, where the backlight units are positioned on the inner sides of the sash, and light guides with parabolic reflectors or optical lenses direct light to the sash, which then reflects it to the display panel, along with a diffusion plate and sheet to ensure uniform illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide plate is used to direct light from backlight units to the display panel, then light distribution is improved, but device complexity and bulk increase
Solution Approach 1:
The patent removes the light guide plate from the conventional backlight structure. Instead of using a separate light guide plate to distribute light, the bottom sash itself is designed with light-guiding functionality through its curved shape, extracting the light guide function from a separate component and integrating it into the existing structural element.
Solution Approach 2:
The patent combines the structural support function of the bottom sash with the light guiding function that was previously performed by a separate light guide plate. The curved bottom sash serves dual purposes: providing mechanical support and directing light from the backlight units to the display panel, thereby merging multiple functions into a single component.
2Illumination intensity
If a light guide plate is used to direct light from backlight units to the display panel, then light distribution is improved, but the apparatus size increases
Solution Approach 1:
The patent merges the light guiding function with the bottom sash structure, eliminating the need for a separate light guide plate. This integration reduces the overall volume of the display apparatus by removing redundant components while maintaining the light distribution function through the curved geometry of the bottom sash.
Solution Approach 2:
The patent extracts the light guiding function from a separate light guide plate component and transfers it to the bottom sash. This extraction eliminates the need for additional space dedicated to a separate light guide plate, thereby reducing the overall apparatus size while preserving the light distribution capability.
3Illumination intensity
If the bottom sash is curved to reflect light, then the light path is optimized, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a curved bottom sash design where the curvature is specifically shaped to reflect light from the backlight units toward the display panel. This curvature optimizes the light path and reflection efficiency, demonstrating the application of spheroidality principle to improve illumination while the manufacturing precision is managed through appropriate curvature radius selection.

AI summary
A curved display apparatus includes a curved display panel, a curved bottom sash disposed at a rear of the display panel such that the curved bottom sash is spaced apart from the display panel, and a plurality of backlight units disposed at opposite inner sides of the bottom sash to irradiate light to the bottom sash. The inside of the bottom sash reflects the light irradiated from the backlight units to the display panel. Consequently, a light guide plate may be omitted from the display apparatus.
