Solution Overview
Problem
Conventional liquid crystal display panels with backlight sources obstruct transparent displays, limiting their application in transparent display technologies.
Innovation Solution
A transparent display panel design featuring a base substrate, light guide substrate, liquid crystal layer, bearing layer with concave structures, and reflecting structures that reflect incident light through the liquid crystal layer to emit light from light emitting regions, allowing for transparent image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional liquid crystal display panel with backlight source is used, then display function is achieved, but transparent display effect is obstructed
Solution Approach 1:
The invention extracts and removes the backlight source from the conventional LCD structure. By eliminating the backlight unit that causes obstruction, the display panel can achieve transparent display effect while maintaining light modulation capability through the liquid crystal layer alone.
Solution Approach 2:
Instead of using a backlight source to illuminate the display from behind (conventional approach), the invention inverts the approach by making the display panel itself transparent and using external light sources or reflected light to achieve display function, thereby enabling both display clarity and transparent display effect.
2Adaptability or versatility
If reflecting structures are added to enable transparent display, then transparent display effect is achieved, but device complexity increases
Solution Approach 1:
The reflecting structures serve multiple functions: they reflect incident light to enable transparent display effect, and simultaneously work with the liquid crystal layer to maintain display clarity. This multi-functionality reduces the need for separate components and minimizes overall device complexity.
Solution Approach 2:
The reflecting structures are selectively positioned only in specific regions where transparent display is needed, rather than uniformly across the entire panel. This localized approach maintains transparent display capability where required while minimizing added complexity in other areas.
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
Enables transparent display effects by reflecting incident light through the liquid crystal layer and light guide substrate, reducing obstruction and enhancing display clarity.
Implementation Method 1
one or more reflecting structures reflect incident light to obtain emitted light, so that the emitted light is emitted by penetrating through the light emitting region of the light guide substrate
