Transparent Display Panel Routing for Uniform Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display devices face challenges in achieving uniform transmittance across their exposed regions, leading to non-uniform light transmission and reduced clarity.
Innovation Solution
The design of transparent display devices includes disposing driving elements, such as data and scan connection lines, in non-exposed regions, allowing for partial overlap to enhance transmittance uniformity by reducing opaque areas in the exposed region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving elements (data and scan connection lines) are disposed in the exposed region, then electrical connection is achieved, but transmittance uniformity deteriorates due to opaque areas
Solution Approach 1:
The patent extracts the driving elements (data connection line and scan connection line) from the exposed region and relocates them to the non-exposed region. This separation removes the opaque connection lines from the visible display area, thereby improving transmittance uniformity while maintaining electrical connection functionality through the non-exposed region routing.
2Reliability
If connection lines are separated and routed individually, then electrical connection is maintained, but device complexity increases
Solution Approach 1:
The patent merges the data connection line and scan connection line into a shared routing path within the non-exposed region. By overlapping these lines in the non-exposed area, the design reduces layout complexity compared to completely separate routing, while still achieving the goal of removing opaque elements from the exposed region.
Data Source
AI summary
The disclosure provides an electronic device including a display panel, a data signal driving circuit, and a scan signal driving circuit. The display panel has a display area and a non-display area adjacent to the display area. The display panel includes a pixel disposed in the display area; a data connection line disposed in the non-display area; and a scan connection line disposed in the non-display area. The data connection line is electrically connected between the pixel and the data signal driving circuit. The scan connection line is electrically connected between the pixel and the scan signal driving circuit. The data connection line and the scan connection line in the non-display area are at least partially overlapped.
