Solution Overview
Problem
Existing display devices installed in transportation boarding spaces have small screens and are distracted by surrounding images, reducing passenger concentration and immersion.
Innovation Solution
A side light-emitting display device that includes a case with a front display panel and side light sources, which emit light through the side surface to enhance immersion and reduce distractions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a front display panel is used to display images, then image information can be provided to passengers, but surrounding images not related to the displayed content appear on the screen which reduces passenger concentration and immersion
Solution Approach 1:
The display device is segmented into two independent light emission paths: front display panel for content information and side light sources for ambient lighting. This segmentation allows the side light sources to provide relevant ambient images without interfering with the main display content, thereby reducing distraction while maintaining information delivery.
Solution Approach 2:
The patent introduces side light sources that emit light from the side surface of the case, adding a new spatial dimension for light emission. This dimensional change allows ambient lighting to be provided without competing with the front display panel for the viewer's attention, eliminating surrounding image distraction while preserving content delivery.
2Area of stationary object
If the screen size is kept small for transportation boarding space installation, then the device fits the limited space, but the screen appears small and reduces passenger concentration and immersion
Solution Approach 1:
By adding side light emission from the case surface, the display device creates a multi-dimensional lighting effect that enhances the perceived size and presence of the display without increasing the physical screen area. This dimensional enhancement improves passenger immersion while maintaining compact installation.
3Object-affected harmful factors
If side light sources are added to emit light through the side surface, then passenger concentration and immersion are improved, but the device structure becomes more complex
Solution Approach 1:
The side light sources are integrated with the case structure, merging the lighting function with the housing. This consolidation adds the immersion-enhancing side lighting capability while minimizing structural complexity by combining multiple functions into unified components.
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 side light-emitting display device improves passenger concentration and immersion by making the screen appear larger and eliminating distracting surrounding images, thereby enhancing work efficiency and leisure experience.
Implementation Method 1
one or more side light sources disposed to be spaced apart from the front display panel and configured to emit light to a side surface of the case
Implementation Method 2
a light diffusion plate configured to enable the light projected from the side light source to be projected from the side surface of the case to the outside while diffusing the light
Implementation Method 3
a heat dissipation panel configured to support the side light source circuit board
Implementation Method 4
a light reflector installed in the case-internal space and configured to reflect the light that is projected from the side light source and proceeds in a direction that becomes distant from the gap so that the light proceeds toward the gap
Data Source
AI summary
A side light-emitting display device includes a case, a front display panel configured to display an image to the front of the case and one or more side light sources disposed to be spaced apart from the front display panel and configured to emit light to a side surface of the case.
