Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation display panels with incorporated thin layers on the front surface of display devices face challenges in improving visibility during light emission, leading to reduced display performance and increased manufacturing costs.
Innovation Solution
Incorporating a transparent conductive sheet with a two-dimensional light emitting element array and a thin layer, along with a transparent substrate forming a light guiding path between the conductive sheet and the light emitting device array, which reduces light loss and enhances light propagation, using micropores in a resin base material with lattice-like louvers or fine fibers to improve display performance and reduce manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thin layer is provided on the front surface of the display panel, then the display can harmonize with natural spaces and provide intuitive touch operation, but the visibility at the time of light emission is insufficient
Solution Approach 1:
A light guide plate is introduced as an intermediary component between the light emitting elements and the thin layer. The light guide plate receives light from the light emitting elements and guides it through its internal structure (with light guide portions and black matrix portions) to the front surface, enabling the light to pass through the thin layer effectively and improve visibility while maintaining aesthetic integration.
Solution Approach 2:
The invention transitions from a two-dimensional display surface to a three-dimensional light guiding structure. The light guide plate has specific thickness and internal architecture (light guide portions extending in the thickness direction, black matrix portions forming partitions), creating a volumetric light management system that enhances light transmission through the thin layer without compromising aesthetic integration.
2Reliability
If conventional light guiding structures are used with thin layers, then basic display function is achieved, but light loss occurs and display performance is reduced
Solution Approach 1:
The light guide plate is designed with spatially varying properties: light guide portions with specific refractive indices and geometries in certain regions to transmit and guide light, and black matrix portions in other regions to absorb stray light and prevent light leakage. This local differentiation optimizes light transmission efficiency and reduces energy loss while maintaining reliable display function.
Solution Approach 2:
The invention optimizes optical parameters including the refractive index of the light guide plate material, the geometry and dimensions of light guide portions, the thickness of the light guide plate, and the arrangement of black matrix portions. By adjusting these parameters, light transmission efficiency is maximized and light loss is minimized, improving display performance while maintaining basic display function.
