Transparent display device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent display devices face challenges in achieving high transparency and thinness due to the need for light guiding plates, which affect the overall transparency and increase the volume and weight of the device.
Innovation Solution
A transparent display device design that incorporates a system light source, either mounted on a side edge of the display panel away from the base or on the base itself, which emits light that is reflected by an object to form spatial light, eliminating the need for a light guiding plate and maintaining the device's thinness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent light guiding plate is disposed at the light incident side of the display panel, then light can be guided to enter the display panel for display, but the overall transparency of the transparent display device is affected and the volume and weight increase
Solution Approach 1:
The patent extracts and removes the transparent light guiding plate from the system by utilizing the display panel's own front surface to guide light directly, eliminating the separate light guiding plate component and its associated negative effects on transparency, volume, and weight
2Illumination intensity
If a lamp box is used as the system light source, then light can be provided to the display panel, but the volume and weight of the transparent display device become relatively great
Solution Approach 1:
The patent merges the light source function directly with the display panel structure by mounting the light source on the front surface of the display panel, eliminating the need for a separate lamp box and thereby reducing the overall device weight and volume
3Illumination intensity
If a lamp box is used as the system light source, then light can be provided to the display panel, but the volume of the transparent display device becomes relatively great
Solution Approach 1:
The patent merges the light source function directly with the display panel structure by mounting the light source on the front surface of the display panel, eliminating the need for a separate lamp box and thereby reducing the overall device volume
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
This design enhances transparency while reducing the thickness and weight of the device, providing uniform illumination and facilitating a more attractive, lightweight, and thinner transparent display solution compared to traditional systems.
Implementation Method 1
light emitted from the first light source
Implementation Method 2
light emitted from the first light source is incident to the display panel reflected by an object placed at the light incident side of the display panel

AI summary
A transparent display device, comprising a display panel for transparency display, a base and a system light source; one side edge of the display panel being mounted to the base; the system light source comprising a first light source; wherein the first light source is mounted on a side edge of the display panel away from the base, and/or is mounted to the base and located at the light incident side of the display panel, light emitted from the first light source is irradiated onto the display panel after reflection by an object placed at the light incident side of the display panel to form a spatial light.
