Transparent Display Pixel Layout for Dark-Point Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display apparatuses face issues with reduced transmissivity due to repair wiring in transmissive areas when a dark point occurs in a sub-pixel, leading to perceptibility of the dark point, increased power consumption, and reduced visibility due to diffraction phenomena.
Innovation Solution
The apparatus is designed with a pixel configuration where sub-pixels are arranged in an X-shape, with transmissive portions between them, and wiring that partially overlaps sub-pixels without overlapping transmissive portions, allowing adjacent sub-pixels to emit the same color when a dark point occurs, minimizing visibility and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repair wiring is disposed in the transmissive area to connect divided sub-pixels, then the sub-pixels can be operated normally, but the transmissivity of the transmissive area is reduced
Solution Approach 1:
The patent moves the repair wiring from the transmissive area (2D plane) to the overlapping region between adjacent pixels, effectively utilizing the third dimension (depth layering) to resolve the conflict between wiring placement and light transmission. This dimensional shift allows wiring to remain functionally connected while being optically separated from the transmissive path.
Solution Approach 2:
The repair wiring is extracted from the transmissive area and relocated to the overlapping region between adjacent pixels. This extraction removes the harmful element (wiring blocking light) from the critical area (transmissive region) while maintaining the wiring's essential function of connecting sub-pixels through alternative routing paths.
2Reliability
If sub-pixels are divided and connected through repair wiring, then dark points can be compensated, but the wiring overlaps transmissive areas causing diffraction phenomena
Solution Approach 1:
The repair wiring is extracted from the transmissive area where it causes diffraction, and relocated to the overlapping region between adjacent pixels. This removes the source of diffraction phenomena while preserving the wiring's ability to compensate for dark points through alternative connection paths.
Solution Approach 2:
The wiring is relocated to a different spatial dimension (overlapping region between pixels) where it no longer interferes with the transmissive area's optical path, thereby eliminating diffraction effects while maintaining functional connectivity for dark point compensation.
3Reliability
If repair wiring is used to connect divided sub-pixels, then normal operation is maintained, but overall power consumption increases
Solution Approach 1:
The repair wiring is extracted from the transmissive area and relocated to the overlapping region, reducing optical interference and improving transmissivity. This spatial reorganization maintains sub-pixel connectivity while reducing the overall energy burden on the display system.

AI summary
A transparent display apparatus includes a first pixel disposed on a substrate and having a plurality of first sub-pixels and a plurality of transmissive portions, a second pixel disposed adjacent to the first pixel and having a plurality of second sub-pixels and a plurality of transmissive portions, and a third pixel disposed adjacent to the first pixel and the second pixel and having a plurality of third sub-pixels and a plurality of transmissive portions, wherein one first sub-pixel of the plurality of first sub-pixels, one second sub-pixel of the plurality of second sub-pixels, and one third sub-pixel of the plurality of third sub-pixels are disposed adjacent to each other. The present disclosure can improve the transmissivity of a transmissive portion, minimize the perceptibility of a sub-pixel in which a dark point has occurred, reduce overall power consumption, and prevent reduced visibility due to diffraction phenomenon.
