Transparent Display Anti-Reflection Structure with Blue Color Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display devices face degradation in transparency due to insulating films stacked on the transmitting area, which also cause color variation issues without effectively compensating for transmittance loss.
Innovation Solution
The implementation of an upper anti-reflection structure with a blue color-compensating layer on the upper substrate, which includes a blue dye or pigment, helps to improve transparency by adjusting the content of blue dye to maintain transmittance without deteriorating it, and a similar configuration on the lower substrate further enhances color correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating films are stacked on the transmitting area to ensure proper operation of the emitting area, then the insulating function is improved, but the transparency and transmittance of the transmitting area are degraded
Solution Approach 1:
The patent applies color compensation by forming a blue color-compensating layer in the transmitting area to counteract the yellowish coloration caused by insulating films. This layer adjusts the color balance to maintain visual transparency while allowing the insulating films to remain in place for proper device operation.
Solution Approach 2:
The patent uses a composite structure combining multiple layers including insulating films and color-compensating layers. The insulating films provide electrical isolation while the color-compensating layer optically compensates for the color shift, creating a multi-functional composite structure that addresses both electrical and optical requirements.
2Reliability
If insulating films are stacked on the transmitting area to ensure proper operation of the emitting area, then the insulating function is improved, but color variation occurs without effective compensation
Solution Approach 1:
The patent forms a blue color-compensating layer specifically designed to counteract the yellowish coloration induced by insulating films. This color compensation mechanism restores accurate color representation in the transmitting area while maintaining the necessary insulating function.
Solution Approach 2:
The color-compensating layer is selectively formed in the transmitting area where color variation occurs due to insulating films, while the emitting area maintains its original structure. This localized approach applies color compensation only where needed without affecting other functional areas of the display device.

AI summary
A transparent display device including an emitting area and a transmitting area is provided. An upper AR structure is disposed on an upper substrate. The upper AR structure includes an upper reflection-preventing layer and an upper color-compensating layer having a blue dye. As a result, the transparency of the transmitting area is increased.
