Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional light-emitting assemblies have a limited viewing angle, restricting the utilization and efficiency of display devices, particularly in applications requiring double-sided image display, which often necessitates mounting two screens back to back, increasing costs and resource wastage.
Innovation Solution
A light-emitting assembly with a lamp bead, mounting plate, and shading face mask, featuring light emergence holes on two sides, reflecting surfaces, and a transparent block made of light-transmitting glass for expanded viewing angles and flexible light direction, allowing light to be emitted from both sides and enhancing the display device's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-faced display device is used, then the structure is simple and cost is low, but the viewing angle is limited and utilization rate is reduced
Solution Approach 1:
The patent introduces light emergence holes on multiple side faces (front, rear, and lateral faces) of the lamp bead shading face mask, transforming the light emission from a single-direction (front-only) to multi-directional (three-dimensional) distribution. This enables viewers to observe the display from various angles including front, rear, and side views, effectively expanding the viewing angle without requiring multiple display devices.
2Adaptability or versatility
If two screens are mounted back to back for double-faced display, then double-sided image display demand is met, but input cost increases and resources are wasted
Solution Approach 1:
The patent enables a single display device to perform multiple functions by providing light emergence holes on both front and rear sides of the lamp bead shading face mask. This allows the same display device to serve as both a front-facing and back-facing display simultaneously, eliminating the need for two separate display devices and reducing resource consumption while meeting double-sided display requirements.
3Illumination intensity
If light is emitted only from the front face, then the structure is simple, but the viewing angle cannot exceed 160° and viewing quality is poor
Solution Approach 1:
The patent divides the light emission function into multiple independent channels by creating light emergence holes on different side faces (front, rear, and lateral faces) of the lamp bead shading face mask. Each face can independently emit light, allowing viewers from different positions to observe the display with optimal viewing quality. This segmentation of light emission paths resolves the limitation of single-directional viewing.
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 significantly expands the viewing angle and improves the utilization rate of display devices, enabling flexible light emission directions and reducing manufacturing costs by allowing single-sided display devices to meet double-sided display demands without the need for dual screens.
Implementation Method 1
one side, facing the lamp bead mounting plate, of the lamp bead shading face mask is provided with a first reflecting surface; one side, facing the lamp bead shading face mask, of the lamp bead mounting plate is provided with a second reflecting surface; and light emitted by the lamp bead is reflected by the first reflecting surface and the second reflecting surface and then emitted out of each of the light emergence holes
Implementation Method 2
the transparent block is made from a light-transmitting glass material
Implementation Method 3
the transparent block is provided with a light emergence face which is frosted so as to form diffuse reflection to emergent light
