Transparent Display Panel with Wrinkle-Shaped Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display panels, such as LCDs, have a black matrix layer on the color filter substrate that obstructs the view of components behind the panel, making it difficult for users to see through.
Innovation Solution
A color filter substrate design featuring a substrate with both color-resistant and transparent sections, where the transparent section surrounds the color-resistant units and has a light transmittance range of 10% to 99.9%, along with a wrinkle-shaped surface to prevent light leakage and enhance visibility by reducing light interference between pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a black matrix layer is disposed on the color filter substrate to define pixel areas, then pixel definition and contrast are improved, but light transmittance and visibility of components behind the panel deteriorate
Solution Approach 1:
The invention extracts and removes the black matrix layer from the color filter substrate, replacing it with a transparent structure. The transparent substrate and transparent encapsulation layers define pixel boundaries without using light-absorbing black matrix material, thereby maintaining pixel definition while allowing light to pass through to components behind the display panel.
Solution Approach 2:
The invention changes the optical properties of the substrate and encapsulation layers from opaque/black to transparent. By using transparent materials for the substrate and encapsulation layers, the display maintains color functionality through the color filter layer while allowing users to see components behind the panel through the transparent regions.
2Illumination intensity
If a transparent substrate is used to see components behind the panel, then visibility of components behind the panel is improved, but pixel definition and light leakage control deteriorate
Solution Approach 1:
The invention segments the encapsulation structure into multiple transparent encapsulation layers (first, second, and third encapsulation layers) that define pixel boundaries. These segmented transparent layers create physical separation between pixels while maintaining overall transparency, allowing both pixel definition and visibility of components behind the panel.
Solution Approach 2:
The invention uses a composite structure combining transparent substrate material with transparent encapsulation materials. This composite transparent structure replaces the traditional opaque black matrix while maintaining pixel boundary definition through the encapsulation layer geometry rather than through light absorption.
3Illumination intensity
If transparent encapsulation layers are used to replace black matrix, then light transmittance is improved, but manufacturing complexity increases
Solution Approach 1:
The transparent encapsulation layers serve multiple functions simultaneously: they encapsulate and protect the pixel structures, define pixel boundaries, and enable light transmission to components behind the panel. This multi-functionality replaces the separate roles of black matrix (boundary definition) and encapsulation layers (protection), simplifying the overall structure despite using transparent materials.
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 users to clearly see components behind the transparent display panel by increasing light penetration and reducing light leakage, resulting in improved visibility and contrast.
Implementation Method 1
The transparent unit comprises a light transmittance, the light transmittance is the ratio of light shining on the transparent unit to light penetrating the transparent unit, and a value of the light transmittance ranges from 10% and 99.9%
Implementation Method 2
a first side of the transparent unit is wrinkle-shaped, and the first side of the transparent unit is perpendicular to a flat surface where the surface is located. the wrinkle-shaped surface is used for preventing light supplied to a first pixel from shining on a second pixel

AI summary
A transparent display panel and a color filter substrate are proposed. The color filter substrate includes a substrate, a color resistant layer disposed on a color resistant section of the substrate, a transparent material layer disposed on a transparent section of the substrate and comprising transparent units, a protective layer disposed on both of the color resistant layer and the transparent material layer, and an electrode layer disposed on the protective layer. Users can see components behind the transparent display panel easily and clearly.
