Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Transparent OLED display panels suffer from interlacing and poor perspective effects due to the arrangement of sub-pixels and transparent pixels, affecting user visual experience.

Innovation Solution

The array substrate design alternates transparent sub-pixels with third color sub-pixels in the same row, spacing them apart to prevent visual interference and reduce diffraction intensity, while maintaining a simplified arrangement of first and second color sub-pixels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transparent sub-pixels are arranged alternately with color sub-pixels in different rows, then the display panel can achieve transparent display functionality, but an obvious interlacing effect and poor perspective effect occur

Engineering Contradiction:

Improvetransparent display functionalityVSAvoidinterlacing effect and poor perspective effect

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the pixel array into specific row groups where transparent sub-pixels are concentrated in odd-numbered rows (1st, 3rd, 5th rows) while even-numbered rows contain only color sub-pixels. This segmentation strategy separates transparent and colored pixel regions, preventing the interlacing effect that occurs when they are mixed throughout the display array.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by creating specific row patterns where odd-numbered rows have a different composition (transparent sub-pixels mixed with color sub-pixels) compared to even-numbered rows (only color sub-pixels). This localized differentiation optimizes the display characteristics in different regions, maintaining transparency where needed while preventing visual interference in other areas.

Inventive Principle:

Principle #3Local quality

2Area of stationary object

If transparent sub-pixels are placed adjacent to each other, then the transparent display area is maximized, but the diffraction intensity increases and visual interference occurs

Engineering Contradiction:

Improvetransparent display areaVSAvoiddiffraction intensity and visual interference

Core Design Contradiction:

Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent uses color sub-pixels as intermediary elements between transparent sub-pixels in the same row. Specifically, transparent sub-pixels are separated by color sub-pixels (e.g., transparent sub-pixel - color sub-pixel - transparent sub-pixel), which act as visual separators that prevent direct adjacency and reduce diffraction interference while still allowing transparent regions to be distributed throughout the display.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Disclosed is an array substrate and a transparent organic light emitting display panel. The array substrate (1) comprises a plurality of pixel units (10), a first row sub-pixel group (10A) and a third row sub-pixel group (10C) each comprise at a first color sub-pixel (11) and a second color sub-pixel (12), and a second row sub-pixel group (10B) and a fourth row sub-pixel group (10D) each comprise a third color sub-pixel (13) and a transparent sub-pixel (14). The transparent sub-pixel (14) and the third color sub-pixel (13) are in the same row, and a plurality of the transparent sub-pixels (14) are spaced apart by the third color sub-pixels (13), preventing a visual effect of a user from being affected.
