Solution Overview
Problem
Existing display devices face challenges in achieving a high aperture ratio and preventing short-circuits between data and reference voltages, while also maintaining high transparency, due to complex sub-pixel structures and increased signal wirings.
Innovation Solution
The design incorporates a display panel with integrated scan lines, light emission control lines, and sub-pixels featuring transistors and a storage capacitor, where common signal wirings are shared between adjacent sub-pixels, and signal wirings are strategically positioned to avoid boundaries, allowing for reduced wiring density and enhanced transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sub-pixel structure becomes complex and the types and number of signal wirings increase, then the functionality and control capability of the display device are improved, but the aperture ratio of the display panel decreases
Solution Approach 1:
The patent combines multiple signal wirings (scan lines, data lines, emission control lines) to share common pathways where possible, reducing the total number of separate wirings needed. Adjacent sub-pixels share common signal lines, merging functions to reduce wiring density and increase aperture ratio while maintaining control capability.
Solution Approach 2:
Signal wirings are designed to serve multiple functions and multiple sub-pixels simultaneously. A single scan line serves multiple sub-pixels, and emission control lines control multiple light emitting devices, making the wiring system universal rather than dedicated to individual elements.
2Measurement precision
If signal wirings are densely arranged to provide comprehensive control, then the control precision is improved, but the transparency of the display panel deteriorates
Solution Approach 1:
The patent utilizes multi-layer structures where signal wirings are arranged in different layers (first substrate, second substrate) to reduce interference and improve transparency. By distributing wirings across multiple dimensions and layers, the design maintains control precision while minimizing the visual impact on transparency.
Solution Approach 2:
Different regions of the display panel have different wiring densities optimized for their specific functions. Areas requiring high control precision have denser wirings, while transparent regions have reduced wiring density or use transparent conductive materials to maintain local transparency quality.
3Area of stationary object
If data lines and reference voltage lines are positioned close together to reduce space, then the area efficiency is improved, but the risk of short-circuit between data and reference voltages increases
Solution Approach 1:
The patent introduces intermediary structures such as insulating layers and protective films between data lines and reference voltage lines. These intermediary elements act as barriers that prevent direct contact between conductors at different potentials, eliminating the short-circuit risk while allowing close positioning for area efficiency.
Solution Approach 2:
Signal wirings are nested within multi-layer structures where conductors are embedded in insulating matrices. Data lines and reference voltage lines are nested in different layers with insulating material between them, allowing compact arrangement while maintaining electrical isolation through the nested protective structure.
