Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with light guide plates and LEDs often experience uneven brightness due to hot spots when using fewer LEDs, leading to reduced display quality.
Innovation Solution
Incorporating a curved light guide plate and a holder that supports this curved portion to guide light uniformly, reducing hot spots and enhancing brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pitch of LEDs is increased to reduce the number of LEDs, then the device complexity is reduced, but hot spots occur causing uneven brightness
Solution Approach 1:
The light guide plate incorporates a curved portion that wraps around the holder, using curved geometry to redirect and distribute light uniformly across the display panel. This curvature enables effective light guidance with fewer LEDs, resolving the contradiction between reduced device complexity and maintained brightness uniformity.
Solution Approach 2:
The curved light guide plate acts as an intermediary between the light emitting diodes and the display panel. It receives light from the LEDs and redistributes it uniformly across the panel surface, enabling even brightness with lower LED density and preventing hot spots.
2Device complexity
If fewer LEDs are used, then the device complexity is reduced, but hot spots cause uneven brightness quality
Solution Approach 1:
The curved light guide plate uses its geometry to redistribute light from fewer LEDs uniformly across the display panel, maintaining display quality and preventing hot spots while reducing the number of LEDs required.
Solution Approach 2:
The curved light guide plate serves as a light redistributing intermediary that ensures uniform illumination across the panel even when fewer LEDs are used, thereby maintaining display quality and reliability.
3Illumination intensity
If a curved light guide plate is used to reduce hot spots, then brightness uniformity is improved, but the holder structure becomes more complex
Solution Approach 1:
The holder is designed with a curved surface that is nested within or integrated with the curved light guide plate. This nesting approach allows the holder to support the curved geometry without adding external structural complexity, while still enabling uniform light distribution.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces or eliminates uneven brightness by ensuring light is emitted uniformly from the light emitting portion, thereby improving the overall quality of the display apparatus.
Implementation Method 1
the curved portion can guide the light of the light emitting component and cause the light to exit uniformly from the light emitting portion after passing through the curved portion

AI summary
The holder is suitable for a display apparatus, where the display apparatus includes a light guide plate and a display panel. The light guide plate includes a light emitting portion and a curved portion connected to the light emitting portion, and the display panel has a bottom surface and a side surface connected to the bottom surface. At least one part of the holder is attached to the side surface of the display panel, and the holder is wrapped with the curved portion of the light guide plate.
